Support » Plugin: Co-Authors Plus » Undefined property: stdClass::$edit_published_posts

  • Resolved Phil


    When I have a custom post type without the ‘edit_published_posts’ capability defined, I get a php notice (in debug mode) when viewing the edit posts admin page for that post type: “Notice: Undefined property: stdClass::$edit_published_posts.” Not a huge issue. I’m just reporting it, and happy to have feedback for a better resolution than below. Here’s my setup.

    • WP debug mode
    • Co-Authors Plus 3.0.2
    • Twenty Eleven 1.4
    • WP 3.4.2
    • no other plugins

    Some code to replicate the problem:

    // in wp-config.php: define('WP_DEBUG', true);
    add_action( 'init', 'sample_cpt' );
    function sample_cpt() {
    	// Register New Post Type
    	$args = array(
    		'public' => true,
    		'label' => 'Events',
    		'supports' => array('title', 'editor', 'page-attributes'),
    		'capabilities' => array(
    			'edit_post' => 'edit_event',
    			'read_post' => 'read_event',
    			'delete_post' => 'delete_event',
    			// etc.
    			//'edit_published_posts' => 'edit_published_events'
    	register_post_type( 'events', $args );
    	// normally might add_cap() to roles here
    	// Create example post
    	$example_post_exists = get_page_by_title('example post', 'object', 'events');
    	if ( !$example_post_exists ) {
    		$example_post = array(
    			'post_content' => 'example post content',
    			'post_status' => 'publish',
    			'post_title' => 'example post',
    			'post_type' => 'events'
    // Go view php notice on admin edit posts page for new Events cpt

    As expected, the notice does not display if you uncomment the 'edit_published_posts' => 'edit_published_events' in the ‘capabilities’ code above. I think the capability 'edit_published_posts' would normally be set by default, unless omitted in an explicit declaration of the capabilities, like my example above. I’ve come across a plugin for which this was the case.

    To get rid of the notice, I’ve altered the file co-authors-plus.php on line 1075

    if ( 'publish' == get_post_status( $post_id ) /*&& ! empty( $obj->cap->edit_published_posts)*/ && ! empty( $current_user->allcaps[$obj->cap->edit_published_posts] ) )

    I added the conditional inside the commented section (/*conditional*/). Uncomment it and the notice no longer displays. The same thing could probably be done on line 1077.

    Feedback welcome. Thanks for a great plugin!
