Preguntas frecuentes

Can I show votes after voting?

You can. Simply use {pro} and {contra} in your texts to show the vote number.

Can I use my own CSS files?

You can. Choose theme as theme in the helpful options. Then create an helpful folder and an theme.css file in it. Fill the theme.css file with your CSS and you’re done.

Are there any shortcodes I can use?

You can. Just use the shortcode [helpful] to output Helpful.

Do I need to consider anything when reporting problems?

Important are the PHP version and the plugin version. You can check the settings of the plugin. In the sidebar you will find what you are looking for.

Is AMP supported by the plugin?

I’m afraid not. I have not dealt with it and only know that there are problems with Javascript. If you have a solution, you are welcome to share it in the forum.

I’m a programmer, can I help?

Sure. Helpful is now also available on Github. I will always update the code first and fix issues with Codacy. You are always welcome to help. Forke Helpful and start bullying!

Can I output the author of the post?

You can. Use {author} for it in your texts. The display_name of the author will then be used.

How can I change the Helpful theme?

Go to Design in the Helpful settings, or visit your WordPress Customizer. There you will find a Helpful menu item.

How can I reset a single post?

First you have to activate the Metabox in the Helpful settings. Once you have done this, a box will appear below the posts (in the admin area) where you can reset the post.

My feedback is not displayed, what can I do?

Switch to the Helpful settings and click on the System tab. There you will find the item Maintenance. Perform the maintenance once. Helpful will do the rest for you.

Hello! Was the post helpful? - that can be answered with YES or NO. You can also send us your feedback. Meanwhile a bit more. For example CSS template for the same adjustment. A plug-in with input and output in performance! --- Hallo! War der Beitrag hilfreich? – das ist mit JA oder NEIN zu beantworteten. Dazu ein Feedback mitsenden ist auch dabei. Indes noch etwas mehr. Bspw. CSS Vorlage für selbige Anpassung. Ein Plug-in mit In- und Output in Performanz! Feedback Ditmar

UI is clean and the plugin is working perfectly. I must also commemorate the author for such a fast response and fix, overall 5/5.

I'm extremely happy to have found this plugin! It's lightweight and the developer behind it has offered top notch support. For more context, I use Helpful on the documentation articles for a commercial product and within just a couple of weeks after installing it I already had enough feedback to see what articles are helpful and which are not. This in turn helped me double down on the articles that were not performing and update them based on the received customer feedback. All in all, Helpful helped me build a better documentation and offer better services to my customers. I highly recommend Helpful!
