Hi David,

I’m currently extending the membership section of my site with a training course. The add-on I’m using for this is provided by MemberPress. During the configuration of the plugin I realized that styles for headlines, buttons etc. are not being pulled from the GPP child theme.

The support team from MemberPress admitted that they are using a separate stylesheet for their MP courses add-on. At my request they offered a custom footer.php file for the plugin with the following content…
```
<?php
/**
 * This template can be overidden in the theme
 */
if ( ! defined( 'ABSPATH' ) ) {
  exit; // Exit if accessed directly.
}
use memberpress\courses as base; ?>
  <footer class="site-footer section is-clearfix">
    <?php do_action(base\SLUG_KEY . '_courses_footer'); ?>
  </footer>
</body>

</html>
```
…and asked me to inject the following code snipped into the function.php of my GPP child theme:

add_action('mpcs_courses_footer', function() { wp_footer(); });

Unfortunately the “overwrite” is not working.

Can you spot an obvious flaw in the suggested procedure which I can play back to the MP support team/ fix myself?

Many thanks in advance.

Beste regards,
Jan

Hi Jan,

Can you try and see what happens if you change opening and closing <footer> element with <div>?

Let us know how it goes.

Hi Elvin,

many thanks. I changed the elements as follows…
```
<?php
/**
 * This template can be overidden in the theme
 */
if ( ! defined( 'ABSPATH' ) ) {
  exit; // Exit if accessed directly.
}
use memberpress\courses as base; ?>
  <div class="site-footer section is-clearfix">
    <?php do_action(base\SLUG_KEY . '_courses_footer'); ?>
  </div>
</body>

</html>
```
…in the respective footer.php file of the course plugin (folder: wp-content/plugins/memberpress-courses/app/views/classroom/ –> suggested by MP support).

Then I cleared the server cache and opened the course page in a private browser tab. The outcome did not change, as far as I can tell. When debugging the button with the developer tool (see screenshot) styles still seem to be pulled from a “user agent stylesheet”.

Any thoughts?

Best regards,

Still trying to wrap my head around this.

To clarify: The goal is to apply a custom footer from MemberPress or is it to add it to GeneratePress’ default footer?

As for the stylings, I’m not sure if this is the fix for this. Normally stylesheets are loaded on the <head> side of the site (unless the style comes from a script hooked to the footer).

The php code basically does “create a hook named ____” inside the <footer>. And then the add_action code basically says to output wp_footer() function here.

But it’s quite hard to know what to do as I’m not exactly sure what’s the expected behavior. Can you explain a bit more on what’s supposed to show on the footer? Is it supposed to load a script from MemberPress?

If so, I don’t see it at all – https://share.getcloudapp.com/lluNpvlm

We don’t know the plugin well enough to confirm if this is a default styling, unfortunately. It seems like it is though because if you go up 1 ancestor on the DOM, you can see that it’s parent (chained-quiz-action) is actually being styled by classroom.css which is MemberPress’ stylesheet file.

Many thanks for explaining the logic behind the styling.

Expected behavior: deactivate or overwrite the classroom.css with the default styles of my GP theme (as per Customizer settings – colors, fonts etc).

I have create a test page and copied the container from the course page (see A – Quizzes) over to a regular page. This will give you a clue on how the course page needs to look like after the desired override works.

Based on what you are saying I sense that we need to move the “override” php-code snipped from the footer of the classroom into it’s header. Rather than manipulating the footer file manually, we could use an Element Hook (wp-head, display rule = classroom pages) to achieve the same.

Any thoughts?

Hi there,

The issue I’m seeing is that none of the theme CSS files are being added to that page. That means you won’t get any of the theme styling for things like buttons.

Is that intentional on the part of the plugin? If so, I would simply ask how to disable that part of the plugin so the theme CSS files are able to load where they’re supposed to.

The function/template they provided doesn’t seem to have anything to do with the styling issue you’re seeing.

Let us know 🙂

Hi Tom,

thanks for sharing your view. I‘ll pass that on and ask for guidance on how to enable the loading of the theme‘s CSS files.

Beat regards,

Hi Tom,

I’m really sorry for the back and forth on this. The feedback I received from the plugin author states as follows:

MemberPress Courses in Classroom mode has custom header and footer. It doesn’t enqueue styles from theme or plugins that are enqueued in the footer. However, most of the time, styles are being enqueued in the header, and the wp-content/plugins/memberpress-courses/app/views/classroom/courses_header.php file contains wp_head() function call. That means, if your theme author enqueues styles in the header, they should be loaded. If that doesn’t work, you can override this file and insert the link to your styles in your custom template.

My take is they are not blocking our theme CSS files from being loaded.

To speed things up I have added a copy of the courses_header.php below:
```
<?php
/**
 * This template can be overidden in the theme
 */
if ( ! defined( 'ABSPATH' ) ) {
  exit; // Exit if accessed directly.
}
use memberpress\courses\helpers as helpers;
use memberpress\courses as base;
$options = \get_option('mpcs-options');
$logo = wp_get_attachment_url(helpers\Options::val($options,'classroom-logo'));

I hope this helps in understanding why the theme CSS files are not being loaded / tells us how to modify the header file?

Any advice is much appreciated.

Kind regards,

Hi there,

All of our CSS uses the wp_enqueue_scripts hook as per WordPress standards. This means that it should be working fine as long as wp_head() exists in the template as you’ve shown.

I wonder if there’s something else removing the GP styles? Have you tried deactivating your other plugins one by one to see if there’s a conflict somewhere else?

Let me know 🙂

Hi Tom,

many thanks for sharing your view. I have gone through the exercise of deactivating all plugins / non-standard themes in a staging environment about a week ago. Back then this was suggested by the MemberPress team also. Last time with no success. I’m more than happy to give this another try. Prior to do so I’ll reset the courses-footer.php file and remove the filter from the function.php of the GP child theme.

Please apologize for this silly question, but how do I recognize (in developer tool) a css file of my GP theme? When debugging the home page there are three css files listed (see screenshot). Unfortunately non of which carries a “GP” in the file name ;-(

Any advise is much appreciated.

Best regards,
Jan

Hi Jan,

You can inspect the page. (make sure all caching is disabled before inspecting)

You can see on the page source which stylesheets are being loaded on the network tab. Here’s an example screenshot – https://share.getcloudapp.com/7KuoKnLp

You hover the mouse pointer on the filename and it’ll show the file path/URL.

On the URL, if you see themes/generatepress or /plugins/gp-premium. That’s from either GP (theme) or GP Premium(plugin).

As for enqueuing/dequeuing. You can ask the handles of the stylesheets you want to dequeue/enqueue.

This is very helpful, Elvin.

I’ll let you know how it goes.

More about this here –

I remember listing the handles on the forums before but I can’t seem to find it. I’ll try to go back to this topic if if/when I find it.

No problem. 😀

Hi Tom,

hopefully this reply from the MemberPress support will help in getting the styles of the child theme activated for on the MP course pages:
If you need to enqueue some css file instead of custom CSS you’d need to add this code to new Snippet:
```
add_action( 'wp_enqueue_scripts', 'mepr_courses_enqueues', 110 );
function mepr_courses_enqueues() {
// Only enqueue style on lesson and course pages
if( is_singular( array( 'mpcs-lesson', 'mpcs-course' ) ) ) {
wp_enqueue_style( 'astra-theme-css', get_template_directory_uri() . '/assets/css/minified/frontend.min.css' );
}
}
```
and replace the 5th line with your style label and path to your CSS file.
How do you amend line 5 of the PHP in order to point to the stylesheet of my GP child theme?

Thanks,
Jan
