[Resolved] Removing featured image action does not work

[Jeffrey]

Hi there!

I created a child theme of GeneratePress and trying to do the following.

1. Remove featured image on a single post
2. Add my own featured image to the single post

Adding my own featured image does work quite well.

add_action( 'generate_after_entry_header', function() {
	if ( ! is_single() || ! has_post_thumbnail() ) {
		return;
	}

	$attrs = array();

	if ( 'microdata' === generate_get_schema_type() ) {
		$attrs = array(
			'itemprop' => 'image',
		);
	}
	?>
	<div class="featured-image youtube-link grid-container grid-parent">
		<?php
			the_post_thumbnail(
				apply_filters( 'generate_page_header_default_size', 'full' ),
				$attrs
			);
		?>
	</div>
	<?php
} );

But removing the GeneratePress featured image does not seem to work. I checked with var_dump() if the remove_action() functions returns true, and it does. Yet when I load my page see two featured images. First one is my custom image, second is the GeneratePress image.

add_action( 'wp', function() {
	if ( is_single() ) {
		var_dump( remove_action( 'generate_after_entry_header', 'generate_post_image' ) );
		var_dump( remove_action( 'generate_after_header', 'generate_featured_page_header' ) );
		var_dump( remove_action( 'generate_before_content', 'generate_featured_page_header_inside_single' ) );
	}
} );

This outputs the following at the top of the page:

bool(true) bool(true) bool(true)

Hope you can help me out.

Hi there,

Have you tried removing the default featured image through the customizer settings?

Try unchecking “display featured image” on post tab.
https://docs.generatepress.com/article/adjusting-the-featured-images/

You may also want to consider filtering the default featured image output to your preference instead of adding a new one and removing the default.

Hi Elvin,

Thank you for your reply. I did check the settings at the customizer tab. If I incheck it, it does not show any image — as expected. If I check it, it shows the two featured images at the single post because of my script.

Now, I did try to use the filter first. I didn’t want to use the add_action method. But when I use the filter you redirected me to, it does not change the featured image at the single post. It only changes the featured image at the archive list, which seems a bit odd to me.

add_filter( 'generate_featured_image_output', function( $output ) {
	return 'FILTERED';
} );

Also, I did not add any specific pages to my child time like single.php or archive.php. It just contains

– admin/
– functions.php
– style.css
– screenshot.png

I got this from your forum of one of your colleagues who made a starterpack for using a child theme with GeneratePress. I’d love to use a filter to change the featured image of my single post, if possible.

Thank you for your help!

Hi there,

Have you tried the generate_single_featured_image_output filter?

add_filter( 'generate_single_featured_image_output', function( $output, $image_html ) {
    return sprintf(
        '<div class="your-custom-classes">%s</div>',
        $image_html
    );
}, 10, 2 );

Using the Customizer option to disable the default featured image should work as well – it’s not aware of your custom function adding another image in, so it shouldn’t be able to prevent it from working.

Tom, this works just great. I was looking for this filter but I guess I wasn’t looking good enough in the docs. Thank you for your time!

Glad I could help! 🙂
