Hide featured image under some conditions

Hi there,

In some specific cases I want to remove the featured image.

Can you let me know what those cases are?

It depend on whether a custom field is filled out the the backend. I offer the bloggers an opportunity to insert a YouTube video instead of the featured image. If they do, I need to remove the featured image from single.

Would the disable element metabox help?

You can also create a layout element for it:

We are on the right track with the disable elements option. But is it possible to do it from the PHP code?

Your function names need to match:

And the syntax for is_single need to be corrected as well:

Wauw.. How could I miss that.

However, it did not help. I have tried to clean up and keep it simple:

add_action('wp','generate_remove_featured');
function generate_remove_featured () {
	remove_action('generate_before_content','generate_featured_page_header_inside_single', 10);
}

That does not work either.

Is the Blog module activated?

If so try this filter instead:
https://docs.generatepress.com/article/option_generate_blog_settings/#options-%E2%80%98single_post_image%E2%80%99

Example:

add_filter( 'option_generate_blog_settings', function( $options ) {
    if ( is_single( '17' )  ) {
        $options['single_post_image'] = false;
    }

    return $options;
} );

Thanks ! That helped :-)

No problem :)
