hmmm, almost...
I'm actually using a wysiwyg field instead of a textarea field, so I tried to adapt your sample code to incorporate the wysiwyg field replacing the Post Content example. But I'm missing something, it's not workingSo to simplify, I tried to conform to your example by adding a textarea field to the CPT called "Snippet Excerpt", snippet-excerpt
- The CPT singular is called Code Snippet code-snippet
- the field group is "Code Snippet before" code-snippet-before
- The wysiwyg field is called "Reason for snippet" reason-for-snippet
- The textarea field is called "Snippet Excerpt" snippet-excerpt
The code below does indeed remove the excerpt field from the Code Snippet CPT, but does leave it for standard posts which is what I want.
But text entered in the textarea custom field does not display as the post_excerpt in the loop even though text that was entered in the standard Excerpt field in older posts still shows even though the excerpt metabox is no longer displayed when editing those posts.
It's probably something simple, but I can't find it. Here's the code that's not working:
/** * using custom field for Code Snippet CPT excerpt **/ add_filter( 'rwmb_meta_boxes', function ( $meta_boxes ) { $meta_boxes[] = [ 'title' => 'Code Snippet Before', 'post_types' => 'code-snippet', 'fields' => [ [ 'type' => 'textarea', 'id' => 'excerpt', // This is the must! 'name' => 'Snippet Excerpt', ], ], ]; return $meta_boxes; } ); add_filter( 'rwmb_excerpt_field_meta', function() { $post_id = filter_input( INPUT_GET, 'post', FILTER_SANITIZE_NUMBER_INT ); return get_post_field( 'post_excerpt', $post_id ); } ); add_filter( 'rwmb_excerpt_value', '__return_empty_string' );What am I missing?
It would be terrific if you could also show how to modify the code so that we could use a wysiwyg field instead of a textarea field -- since we would want html-formatted text displaying as the excerpt. In my particular case the wysiwyg custom field would be "Reason for snippet" reason-for-snippet in the Code Snippet Before field group.
another example that doesn't work:
add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) { $meta_boxes[] = [ 'title' => 'Story Field Group', 'fields' => [ [ 'type' => 'textarea', 'id' => 'textarea_6dgymvsrfq5', 'name' => 'Full code snippet', 'sanitize_callback' => 'none', ] ], ]; return $meta_boxes; } );
