Topic: Remove container with no “Updated Date”

I have a container, inside is a label (Headline) and another headline field that contains dynamic data (Post date – updated).

I want to hide this container if there is no “updated date”. But in order to use the REMOVE CONTAINER CONDITION in the block settings, I need to know the META FIELD NAME.

Does anyone know the meta field name for the updated date? Or if there is a document that lists all the meta field names so i dont need to ask again in the future.

Thanks
Chris

Hi there,

the dates are not saved in Post Meta, so there is no field to check for.
Instead you could use a PHP Snippet with the render_block hook to remove a Container Block with a specific class if there is a) no modified date or b) the modified date is the same as the published date.

Here is the PHP Snippet:


add_filter( 'render_block_generateblocks/container', function( $block_content, $block ) {
    if ( 
        ! is_admin() && 
        ! empty( $block['attrs']['className'] ) && 
        strpos( $block['attrs']['className'], 'post-updated' ) !== false 
    ) {
        $post_modified_date = get_the_modified_date();
        $post_published_date = get_the_date();
        if ( ! ( $post_modified_date && $post_modified_date !== $post_published_date ) ) {
            $block_content = '';
        }
    }

    return $block_content;
}, 10, 2 );

Then select the Container Block, in Advanced > Additional CSS Classes add: updated-date-container

Could be me but it seems to be doing the opposite. Removing the block if it DOES have a date. Keeping it if it doesnt.

We all have those days lol.

Page doesnt seem to want to load using the new one. Just get a blank screen until I remove the Additional CSS Class.

I tried clearing my browser cache and also purged my hosting cache.

EDIT: Managed to sort it. It was the is_empty


add_filter( 'render_block_generateblocks/container', function( $block_content, $block ) {
    global $post;
    
    if ( 
        ! is_admin() && 
        ! empty( $block['attrs']['className'] ) && 
        strpos( $block['attrs']['className'], 'updated-date-container' ) !== false 
    ) {
        $post_modified_date = get_the_modified_date( '', $post->ID );
        $post_published_date = get_the_date( '', $post->ID );
        
        if ( empty( $post_modified_date ) || $post_modified_date === $post_published_date ) {
            $block_content = '';
        }
    }

    return $block_content;
}, 10, 2 );
