Failed to use tinyMCE within a metabox

I read somewhere tinyMCE instances don’t get along with metaboxes and so far I could find no fix for my issue

Yes I have had that happen to me. Although I do have an instance where is seems to work OK, although I’m not exactly sure why. I’ll look at the code later and try and see what makes it play nicely.

OK The solution is not to use a meta box. It is quite well documented in wp_editor() https://developer.www.ads-software.com/reference/functions/wp_editor/

Unless you just use quicktags ( text ) the tinyMCE does not like being moved. It normally works OK until it is moved, then it goes haywire.

So the solution is to fix the output in the DOM.

For a CPT to fix the output position, don’t use metaboxes (moveable) but the action 'edit_form_advanced'

You can then position initially the other metaboxes above or below with context below set to advanced above set to normal

So example

add_action('edit_form_advanced', array( $this, 'inner_custom_editor' ) );
public function inner_custom_editor( $post ) {
               if ( 'myCPT' !== $post->post_type) {
		    return;
                }
		echo '<p>some markup</p>;
		wp_editor( $mymeta, 'my_id', $settings );
                echo '<p>some markup</p>;
	}

I did appreciate your hint, thanks!

Though I didn’t properly get the way you added the edit_form_advanced action.

I eventually used something like what follows.

add_action('edit_form_after_title', 'custom_tinymce_editor');
function custom_tinymce_editor () {

   global $post;
   if ( 'my_custom_post_type' !== $post->post_type) {
    return;
   }
   $custom = get_post_custom( $post->id );
   $desc = $custom[ "_desc" ][ 0 ];

   $textarea_id = 'desc';
   echo '<p>something to display</p>';
   $wp_editor_settings = array(
                                'tinymce' => true,
                                'textarea_name' => '_desc',
                                'quicktags' => false,
                                'media_buttons' => true
   );
   wp_editor($desc, $textarea_id, $wp_editor_settings);
   echo '<p>still something to display</p>';
}

This way I avoided having the TinyMCE code mixed with the code of a meta box (it could still work, but it gave me an unpleasant idea of disorder).

I’m still puzzled, though, because I’m still using a code that mentions meta…

update_post_meta( $post->ID, "_desc", $_POST[ "_desc" ]);

But desc is no more handled by a meta box… should I mind that?

Thanks!

Your code is fine, my code was just part of a class thats why the array($this wa s there.

I would have done it slightly differntly. You don’t need the global $post as the hook passes post as a parameter
i.e. function custom_tinymce_editor ($post) {

And I would have used get_post_meta rather than get_post_custom
i.e. $desc = get_post_meta($post->id,'_desc',true);

Also you need to sanitize $_POST[ “_desc” ]

e.g. update_post_meta( $post->ID, '_desc', wp_kses_post($_POST[ '_desc' ]));

There is no relationship between meta-boxes ( a display element ) and post-meta ( a custom field) as such, so nothing to be concerned about

Many thanks, Alan!
