Rich Custom Field for Custom Post type not saving
The second parameter on wp_editor is the “metabox” field id/default name and you need to put this in the “update_post_meta” for wordpress to know what to save or specify the correct textarea_name. In display_educadme_related_resources() use: $educadme_resources = get_post_meta($post->ID, ‘related-editor’, true); And in save_educadme_related_resources() use: update_post_meta($post->ID, “related-editor”, $_POST[“related-editor”]);
