  • Mike

    Is there a way to customize the results page? I do an mental health quiz. I don’t think “congratulations! You passed.” is the best response to having a problem. I would also like to add a hyperlink the results page too. Thanks for the great plugin.

    • Hello Mike and thank you for using HD Quiz!

      You can customize the results text by editing the quiz options. You can get to the quiz options by going to HD Quiz -> Quizzes, then selecting the quiz you would like to edit. From there you will be able to customize almost every aspect of the quiz including the text for passing or failing the quiz.

      As for adding a link, you should be able to add a link via HTML in the Quiz pass text area. So for example,

      <a href = "####">link text</a>

      where #### would be the URL you want the link to send to, and link text would be what you you wish the clickable text to be.

      I think that the ability to add a link to the quiz results is a great idea though, so I’ll add in a dedicated way to do this is the next update.

  • Wendy Mayes

    Hello. I am a real newbie as you will see from my question. I have made a quiz but when I paste the code into a page all I see is a “Finish’ button. What am I doing wrong?

    • Hello Wendy, it sounds like you created the quiz, and created some questions, but never attached those questions to a quiz.

      When editing or creating a new question, the right sidebar will contain a list of all of the quizzes you’ve created – you’ll need to select the quiz the question belongs to here.

  • Chartreuse

    Hello, your quiz maker looks excellent. how can I use my quizz to collect email addresses or Facebook followers?

    • Hello Chartreuse,
      there is currently no direct option in HD Quiz to collect personal information from any quiz takers, but there may be a viable solution for you coming out soon!

      The next version of HD Quiz (will probably be released early next week) contains some considerable upgrades to the text that appears when a quiz is completed. This new update would allow you to easily add links to the quiz results allowing you to do something along the lines of “If you enjoyed this quiz, then please follow us on facebook or sign up to our newletter.”

      This way whenever someone completes a quiz, they would get a call to action to follow you on Facebook or subscribe to your list.

  • joao lucas

    Hello, i’m trying to add a image as an answer but I just can’t. I just click at the image saying 400×400 and it just doesn’t open any window for me to select the image. Please, help.

    • Hello Joao,

      it sounds like your site has a jQuery confliction in the admin area.

      Are you using the latest version of WordPress?
      Try upgrading if there is a version available to you.
      HD Quiz is only officially tested with WP 4.3+

      What theme are you using?
      Try temporarily changing your theme to the default Twenty Fifteen
      It’s possible that a poorly coded theme could have errant functions and scripts that are interfering. Changing to Twenty Fifteen will help you narrow down the possibilities.

      Just to test, try disabling all other plugins and see if you are now able to add images to HD Quiz
      If disabling all other plugins allows HD Quiz to work, then we know that the cause of your problem is one of your other plugins. Now you can enable your plugins one by one until you find the one causing the problem.

      Please let me know if you need further help.

  • Julie May

    Do you know when this feature might be available?

    • Add ability to add a small writeup for each question that would be displayed underneath the question on quiz completion.

    • Hello Julie,
      this feature is actually done, just not released yet as it has not been fully tested. I have sent you an email with the next version of the plugin – just remember that it IS unofficial and may contain bugs.

      Please let me know if it works for you, or if you come across any problems.

  • Yes Agency

    Hi, I would like users to be able to answer with a text answer rather than multiple choice. Is this possible?

    • Hello Yes Agency,
      This functionality is not currently in HD Quiz – HD Quiz uses multiple choice only.

      Unfortunately, there are also no plans to bring this functionality in the near future, but if enough people request it I will bump it up on my feature to do list.

  • Gea Suarez Bing

    Hola, gurda los resultados? no pude encontrarlos

  • Karin Persons

    Hi, I wonder if I can use HD quiz for a personality-type of quiz. In that case there will be no right or wrong answers, just ”mostly A=…” etc.
    thank you for your reply
    Karin The Netherlands

    • Hello Karen,
      greetings from Canada!

      HD Quiz is NOT compatible with personality type quizzes at this time. It is something actively being worked on, but will not be ready for another few months.

  • Your plugin rocks …..maybe just add a hook to mycred to award points to taking the quiz

    • Thanks for your support m4dgaming!

      I’ve never heard of the mycred plugin before but I’ll look into it and add support if possible.

  • Sarah Schauerte

    I installed this Plugin, which looks great, but the answers to the quizzes are so light they’re barely readable (even when I scroll over them). Is there a way to change the font/background/etc? I don’t see that option anywhere. Also, the name of the quiz isn’t appearing on my site (it start immediately with question #1). I’m running WordPress 4.4.1. Thank you!

    • Hi Sarah,
      this is probably an issue with your theme overriding HD Quiz’s style. If it’s OK with you, please send an email to dylan AT harmonicdesign.ca (replacing AT with the @ symbol) with a link to the page with HD Quiz on it.

      I’ll take a look at it and send you some minor code that you can add to your theme’s stylesheet to force better font colours and contrast.

      • Sarah Schauerte

        Thanks, that’s really nice of you! Really appreciated.

  • Egitimilk Kaliteli Egitim

    Hello. Thks for great plugin. My problem is when ı finish exam there is a featured ımage. how can ı change that.

    • Hello Egitimilk,
      you actually found a bug with the old way the shortcode handled featured images. I am sorry that this happened to you!

      I have updated the plugin to remove the featured image in the results. Please deactivate HD Quiz, delete, then reinstall from the WordPress repository to re-download latest files.

      The next feature version of HD Quiz (to be released later this week) will allow you to upload a different featured image for Quiz Pass and Quiz Fail results.

      Thank you for bringing this bug to my attention.

  • Sammie

    Hallo i have added the a few questions but when i want to preview the questions, it doesn’t show anything, please assist

  • Sammie

    Hallo i have added a few questions but when i want to preview, there is nothing showing, please assist

    • Hello Sammie,
      It’s not possible to preview a question but it is possible to preview a Quiz.

      You need to preview whatever page or post you placed the Quiz shortcode on, not the individual questions.

      • Sammie

        i have tried but nothing can i give you my wp details u see what could be the issue?

  • shoppaholic2016

    Hi, great plugin! Just wondering if it’s possible to find out how many people took your quiz or what their answers/total score were. Thanks in advance!

    • Hello shoppaholic2016,
      HD Quiz does not currently store any of that information to the database, but I do plan to add something similar in the future.

  • 239u4-8

    hi i really need you help. i was wondering why i cant see the quiz on a mobile? i tried it using the apple stimulator and the only thing that didnt work was the quiz. i extremely like your plugin and would love to use it but can you please help me with this problem.

    • The quizzes are definitely mobile friendly, so there is likely something in your theme that is stopping them from appearing on your site on mobile devices.

      Can you please send me a link to a quiz on your site? I’ll take a look and let you know.

      • 239u4-8

        actually my site isn’t live yet. do you know any other way you could possibly help me?

        thank you for replying

        • Hello 239u4-8,
          unfortunately, the only way would be to look at your CSS and find the attribute that is hiding the content. The easiest way to do this is to make your browser window as small as possible (which will force it to show the mobile/responsive styling), then use your browsers inspect feature to track down your errant code.

  • Austine

    Hello iam unable to access more options on the quize settings like how to set the timer etc i didn’t get to see the option there. also ther is no fill in the blank question. am i looking at the wrong places?

    • Hello Austine,

      to edit individual quiz settings, go to HD Quiz -> Quizzes, then select the quiz you wish to edit. This will take you to all of the advanced settings and options for the quiz. HD Quiz does not have a ‘fill in the blank’ question type; only multiple choice.

  • John D

    I am getting two start buttons when I use wordpress pagination. How do I get rid of the one? Here is a link to the problem page. http://b4therapture.com/blog/quizes/

    • Hello John D,
      I took a look at the link you sent and the problem is that you are using both WP Pagination and jQuery Pagination. Please edit your first question “Where was the book of Revelation written” and uncheck ‘pagination’.

      If you would like to know what the difference between WP Pagination and jQuery Pagination, then please take a look at this link. https://harmonicdesign.ca/hd-quiz-pagination/

  • Ksistof Jusel

    Hello, Dylan, I like Your plugin HD Quiz very much and I would like to ask how to count , sum results from multiple quizes? Thank You


    I love this plugin so much and I would actually love to have an import and export questions into quizzes feature. This will make it perfect and recommend it for schools in my local area. I will really appreciate your response

      thank you for your kind words!

      HD Quiz uses a custom post type to manage all of the questions – this means that you can use WordPress’ built in export and import tool to import/export quizzes.

      Goto tools -> export, then select Questions. This will allow you to export all of the questions. You can then use this file to upload to another installation with HD Quiz installed to import all of your questions again.

  • nikos583

    Great plugin guys, love it! I need help with Tips. How can I add tip/hint to each question?

    • Hello nikos583,
      thank you for your support!

      You can add a tip/hint to any question by entering content into the “Tool tip text” section of the question edit page. Just please note that tips are text only, meaning that you cannot add links or images to it.

      • nikos583

        Thank you very much for the quick reply!

  • Rachel Kaisler

    Hi! I’m looking to use a quiz to quickly capture information from a potential customer. This would include their specific answers to the quiz questions itself. Is it possible to receive all of the information inputted into our webpage through this application? Thank you!

    • Hello Rachel,
      HD Quiz does not store any user inputted information, so it would not be possible in it’s current state.

      Perhaps the popular Contact Form 7 plugin can do what you want. It’s not a quiz or anything, but you could have ‘questions’ and ‘answers’ and email yourself the results. The downside would be that it would not be able to mark right or wrong answers or give or score.

  • Teena Barnett

    How do I change the background color of the quiz passed text and the quiz failed test? It’s randomly two different colors within the same box.

    • Hello Teena,
      I am not sure what you mean by “randomly two different colors within the same box” unless you are referring to the two tone color for the results section itself and the share section within it. Please see the attached image for reference.

      If yours looks different, it is because your theme is overriding it.

      You can always add CSS to your theme to set the colors to anthing you want.

      To change the ‘color one’ of my reference image, add the following:

      #hdQuestionnaireContent #results {background:#FFFFFF !important}

      That would change the background to white. Replace #FFFFFF with whatever color you want. The ‘color two’ of my reference image can be modified with the follow:

      #hdQuestionnaireContent #hdQuShare {background:#FFFFFF !important}

      Once again, the above line would force the background to be white.

      I hope this helps!

      • Teena Barnett

        Thank you!

  • Gavin Watts

    Great plugin…how does one change the font size for the questions?

    • Hello Gavin,
      I’m glad that you are enjoying HD Quiz!

      HD Quiz automatically types to your theme, so if your theme headings are large and blue, then HD Quiz will make it’s headings large and blue as well.

      Luckily, it’s very easy to override this yourself using CSS.

      Edit your themes CSS and add the following line, replacing font-size: 22px with your desired size.

      #hdQuestionnaireContent h3 {font-size: 22px !important;}

      • Gavin Watts

        Thanks Dylan this will solve a headache for me…If ever you find yourself in Cape Town contact me and we will have a beer….

  • svasil

    Hi sir, you have a great plugin! Just wondering if it’s possible to change the range of the questions? And put the questions in groups? (Geography, History etc…)

    • Hello svasil,
      I’m glad you’re enjoying HD Quiz!

      The best way is to use a combination of the new Title type of question, mixed in with the Pagination feature.

      So you’d add a new question called “Geography”, but do not add any answers. Instead check off “Question as Title” and “Paginate”.

  • svasil

    Did I can drag and drop the questions to change our range?

    • Hello svasil,
      for re-ordering questions, I’d recommend using the Intuitive Custom Post Order plugin. This will allow you to drag and drop.

      • svasil

        Thanks! It works!!!

  • Hase

    Thank you for that nice plugin, great job. It is really easy to learn and running smoothly! I have got a question concerning the logic of the question and answers. As far as I can see, it is not possible to insert a photo into the correct answer, is it? Say, I would have a multiple choice text question with 4 possible answers (and no photos at all). If the user clicks the right one I would love to say something like “Great”, together with a nice picture of the answer item – nearly as you have already inserted it for the wrong answerI Is there any possibility to insert that into further updates?

    Thanks for your answer in advance.

    • Hello Haze,
      thank you for using HD Quiz!
      That’s a pretty interesting and unique use case there; I like it!

      Currently, there is now way to show a per-question result when the user gets the question correct. I only added in if they get it wrong because I figured if they got the right answer, then they shouldn’t need an explanation.

      To be honest, I’m not sure if this is something I’ll add into a future update as it would add a whole new level of complexity to the result checking, and I’m not sure if it’s a feature enough people would use to make it worth while (if anyone is reading this and would like this feature, please let me know!). I’ll have to think about the best way of adding it in, so don’t count it out yet.

      As for adding an image to that section? Great idea! I’ll add it into the next release.

      • Hase

        Hi Dylan,

        thank your for your superquick and kind reply! Actually i have already guessed that this would be a lot of work for you – but was hoping for lots of fans to having you asked the same before and you considering to implement this … 😉

        Sorry for my not understanding but I don’t really get your idea of what you mean by “image to that section”? Where would that image appear?

        Just to explain what I had in mind with my question: Given that questions with images are always nicer than ones without … If I have a text question (“Which animal is the biggest?”) with text answers (Elephant, Mouse, Dog, Whale), I wouldn’t take one of those answers as the one and only picture for the post because whichever of the four possible I would take – it would influence the user’s answer. If I choose the “Image Answers” option instead I need at least four images which I have to find, to edit, to name with source etc. and to load up. Having an image together with the right answer seems to be a nice compromise to me: I only have to have one image and the user will get a nice “gratification” for his efforts.

        May I ask you another question? To completely localize your quiz for other languages it would be very useful to have the possibility to translate the score response “You Scored … or …%”, too. That may be a wish of almost everbody who uses HD quiz outside the English-speaking market.:-)

        Sorry for my long reply, dear Dylan, and best wishes

        • Hello Hase,

          thank you for your in-depth response. You bring up a great point about the “You scored…” section. I will add it to the HD Quiz options page next update.

          For the “image to that section”, I am referring to the individual quiz options page – the Quiz pass text and Quiz fail text. These two options are utilizing the WordPress visual editor tinyMCE. It’s possible for me to add in an ‘add media’ button that will allow you to upload an image and ‘insert into post’, just like you would for a normal WordPress page.

          • Hase

            Hi again, Dylan,
            ah, okay. That function has already come to me with my theme, obviously. I had no difficulties to insert an image for each question right from the beginning. 🙂

          • Hi Haze,
            just to be clear, I am talking about the individual questions page (my previous reply was not very well made. edited for clarity). Your theme would have absolutely no control over this section unless it is overriding all tinyMCE instances – which would be a very very bad thing for your theme to hijack!

            I am talking about adding the ability to upload an image and insert it into the text area, just like you can do with any normal WordPress page. Please see attached screenshot to see the section I am referring too. So, not the featured image that appears before each question, but an image that can be inserted into the “Text that appears if answer was wrong” section.

            Hope this makes sense!

          • Hase

            Dear Dylan,
            Thank you for replying again and get this clear. Yes, I had already found that section and tried to insert an image – that was running perfectly. It’s very nice and very near to the opportunity I would love to have for the text that appears if the answer was right. 😉

  • Sandra Koryszewska

    Hi, awesome plugin! But I got a huge problem with the result page – it opens up in a new browser window, without CSS, it just looks dirty. I’d like it to look just like your demo quiz (results appearing on the top of the quiz).
    How can I do it?
    Here is a link to the problem page:

    • Hello Sandra,
      I have taken a look at the link provided, and unfortunately, the problem is a with your theme.

      All of your pages seem to abruptly stop without displaying the footer, any footer scripts, or even the enclosing and tags. This is a pretty serious issue and should be looked at as soon as possible as it essentially breaks the vast majority of any WordPress plugin.

  • kir1akos

    hello and thank you for the great plugin. Very usefull! But i have a question. how can i collect the results from the users? for example i want to know who scored perfect and know his/hers time and some personal info (email or facebook/twitter acount). thank you!

    • Hello kir1akos,
      I am glad you are enjoying HD Quiz. Unfortunalty, HD Quiz does not store any user information, so there is no way for you to retrieve previous results or personal information from a quiz taker.

  • Peter Feldman

    Hey Harmonic – good work, your plug in offers just what we need. Question about customizing results page – any options on the correct answer indicator – some were confused with just a green line below the answer because the incorrect answer still shows the radio button selected and in green. Can this be augmented, enlarged or maybe add an X or check-mark next to correct answer? Is this something you can customize for us? Thanks.

    • Hi Peter,
      I’m glad you are liking HD Quiz so much!

      If you can send me the link to one of your quizzes, I can write some custom CSS for you to enter into your theme that will make the ‘correctly answered question’ more apparent. I’m personally a fan of subtle indicators but understand that it isn’t for everyone!

      • Peter Feldman

        Hi Dylan, we’re just in testing right now and won’t be rolling out the quizzes for a few weeks – also updating theme, so css will change.
        Now that I know it is possible I’ll get approval to use your plug-in from my client and also ask them to make a contribution for the custom work. Thanks!

        • Peter Feldman

          Hi Dylan, we are now working on building our new site and would like your help with some custom CSS – are you available this week? Is this the best place to provide direction on what we want do change or do you have an email I should send to? Please contact me at peter@etainia.com – I hope to have instructions ready tomorrow and styling on the new site ready by Wednesday.

  • Hey, great plugin.

    Can i make to show the result on the same page? Now it redirect to a page. I want people to stay on the same page

    • Hello Cristian,
      HD Quiz loads on the same page. If it is not for you, then that means there is a problem with your theme not loading footer scripts.
      If you can send me a link to your site, I can confrim this for you and send you an easy way to fix your site. This fix would not only get HD Quiz working perfectly for you, but would fix a myriad of other problems on your site as well!

      • Hi Dylan, This is the page http://managersacademy.ro/membri/m1/quiz/

        Thank you for looking into this

        • Hi Cristian,
          I have taken a look and I have to admit, I’m scratching my head here.

          I was half right that there is something in your theme conflicting with the loading of footer scripts, but I am unfortunaly unable to know why without admin access to your site.

          Please try each the following and see if it works.

          OPTION 1: The problem is that you site is not writing the quiz settings. Things like if there is a timer on the quiz or if the quiz should mark right/wrong answers.

          Please go to HD Quiz -> Quizzes -> click on your quiz. This will take you to the quiz option page. Set any settings you want here then save.

          Now you can check the quiz again and see if everything is working.

          OPTION 2:

          If option 1 fails, then we can try incerting the settings directly.

          Please edit footer.php in your theme folder (‘managersacademy.ro/wp-content/themes/roots/footer.php’), and copy/paste the following code at the top.

          var pluginURL = “http://managersacademy.ro/wp-content/plugins/hd-quiz/”;
          var jPagination = “no”;
          var hdQuizTimer = “no”;
          var quizTimerS = “270”;
          var hdQuizShowResultsCorrect = “yes”;
          var jPagination = “yes”;
          var jPaged = “1”;
          var jPagination = “no”;
          var hdQuizTimer = “yes”;
          var quizTimerS = “270”;
          var hdQuizShowResultsCorrect = “yes”;
          var jPagination = “yes”;
          var jPaged = “1”;

          • Thank you Dylan!

            Option 2 worked. Iuhuu! 😀

          • That’s great!

            You can edit individual quiz options. such as the quiz pass / fail text by going to HD Quiz -> Quizzes -> click on your quiz. This will take you to the quiz option page. Set any settings you want here then save.

            There are also general global options located at HD Quiz -> About / Options.

  • Glenn Rowe

    Hi, great plugin in but for some reason the images for the sharing buttons (twitter and facebook) are not showing. any ideas ? I’ve switched to twenty Fourteen theme and no change and also deactivated all plugins, again no change ….https://www.theallseeingeye.com/music-quiz/

    • Hi Glen,
      Thank you for using HD Quiz!

      I have taken a look at your site. What’s interesting is that you site is able to load the images on my phone, but not my desktop. This is particularly interesting as there is no code difference in HD Quiz between the two.

      Because of this, I’m thinking that this might be a caching issue on your site (I see you are using WP-Super-Cache).

      Please first try and clear your site cache in WP-Super-Cache and see if it works now. If not, try clearing then disabling WP-Super-Cache (temporarily) to see if that fixes it for you.

      If neither of these works, then I can send you a custom fix that will load the image source directly instead of through jQuery.

      • Glenn Rowe

        Dylan, Thanks for your reply, much appreciated.

        I have worked it out, the problem was with ‘Rocket Loader’ in Cloudflare, with this switched off, it now works. Thanks.

  • Dead Skunk

    Congrats on a great plugin. I was really surprised someone had done a multiple choice plugin with so much configuration. One issue I am seeing is I am not able to use multiple quizzes on the same page. The first one always works, subsequent ones don’t, and when I select an answer in any quiz other than the first it actually triggers a selection in the first quiz (i.e., I select option #3 in the second quiz and the radio button for option #3 in the first quiz is selected). If I submit any quiz other than the first I am sent to a new page with the answer, etc., so I believe the JavaScript is binding to only that first one and catches the submit, while the others are not bound. Maybe this could be solved by added an id selector to each quiz and binding to it, or adding a check for multiple quizzes in the JS and if multiples are found iterating over each one?

    Just for insight into why I have this: I have a client who is going to post one-question quizzes on blog posts. So if she has two or more blog posts with a quiz the second one (and any others) will not work.


    • Hello Dead Skunk,
      thank you for your support of HD Quiz.

      When I first developed HD Quiz, I never even considered the possibility that people would want to use more than one quiz on a page, but you are now the third person to bring it up!

      You are correct that it is because the quizzes do not use unique IDs (why would they need unique IDs? People will only be using one quiz per page!). I’ll try and spend some time this weekend to push out an update that will wrap each quiz in it’s unique ID so that the jQuery will only target the correct quiz. Stat tuned!

        Wow, thanks for the quick answer and even more for the willingness to consider a change. I’ve been a developer for 20 years and can’t count the number of times this exact thing has happened to me. But it’s far better to add a feature enhancement people ask for than to build in a lot of stuff they never need. Cheers.

    Hi for some reason when a Quiz is completed all I get at the bottom of the page is a grey box with no customised text in which I have put in on the options, picture attached. I have tried loads of the other options but no joy in showing the outcome to a visitor. Any help much appreciated and apart from that the plugin looks great so really want to get this running. https://uploads.disquscdn.com/images/67b083f98217fc1de3a06610a83869119fba1e848ee8dead0bd48273a2d987f8.png

      I should have mentioned I am using the woocommerce store front theme and all default settings on that

      • Hi Steve,
        This is the first time I’ve seen this problem. Are you able to show me a live link?

        • Steve Clews

          Hi and thank you for getting back to me, just answer everything yes and or no on the quiz as get the same outcome link https://bos.witchcraft.uk.net/?p=568

          • Hi Steve,
            thanks for sending!

            I just took a look and found the problem, but I do not know why the problem exists.

            The problem is that your server is blocking the results file from loading. “Failed to load resource: the server responded with a status of 403 (Forbidden)”. This is most likely because the file does not have permission to load. The file is plugins/hd-quiz/result.php

            Are you using a security plugin by chance? Try white labelling HD Quiz, or change the folder/file permissions for results.php

            Fantastic and thank you so much. I did a security scan on my host CP the other day and it was recommending a folder update which I did, fortunately I was able to roll that update back and that has worked 100%. Thank you for a great plugin and fast response and as you said it was a folder permission. 5 out of 5 stars from me.
