[Resolved] generate_featured_image_output not working

[Zarar]

This filter doesn’t seem to be kicking in:

This should result in no featured images being displayed anywhere, but they’re all still showing up.

add_filter( 'generate_featured_image_output', function( $output ) {
	return "";
}, 11, 1 );

What could I be doing wrong?

Hi there,

You can disable the featured image at customizer > layout > blog > featured image.

I don’t see the point to use this filter.

Let me know if there’s a specific reason.

[Zarar]

The point is that I don’t want to display the featured image in very specific cases. For example when the post is tagged with a particular item and a YouTube video exists in the post. Only in those cases do I not want to display a featured image on the page.

[Ying]

So you are going to add some condition to the filter so it only removes the featured image for those cases?

Can you show me an example?

In this case I don’t want a featured image displayed since it is redundant as there’s already a YouTube thumbnail with the same image on the screen.

[Ying]

Is the only difference between this post and other posts the Youtube video?

If so, try this snippet:

add_action('wp',function() {
	 $post_content = get_the_content(get_the_id());
         if ( strpos( $post_content, 'wp-block-embed-youtube' ) && is_single() ) {
             remove_action( 'generate_after_entry_header', 'generate_blog_single_featured_image' );
         }
}, 100 );

Thank you for that solution. I am OK using it but it seems a bit of a hack. Is there a reason why generate_featured_image_output doesn’t work as advertised here? https://docs.generatepress.com/article/generate_featured_image_output/

Hi Zarar,

generate_featured_image_output is for archive page featured images.

The solution provided by Ying is viable.

[Zarar]

Thank you. I suggest updating the documentation to reflect that explicitly.

[Zarar]

Marking this as resolved. Thank you.

[Ying]

Glad it works 🙂

Thank you. I suggest updating the documentation to reflect that explicitly.

In the documentation of generate_featured_image_output, we indicated that it alter the HTML of the featured image on the posts/blog page, this doesn’t include the featured image on single post page.

Hope that’s clear 🙂

[Zarar]

It is not. As Fernando said, saying “archive pages” is more clear.

When I read that I thought “posts” page meant pages where a post is displayed.

[Ying]

If you go to settings > reading, you will see the Posts page option under Your homepage displays section.

In WP, posts page is the same as the blogpage officially, but I agree we should’ve added archives too as it also applies the change to archives 🙂
