spstiengI had it working, but now it's not working any more.
I've added some custom metaboxes to my edit post page and I have the following problems:
1. Meta data not stored (was working)
2. Medta not deleted when empty (was not working wen 1. was working).
Is there something wrong with my code?
I got the following code in my functions.php file:
add_action( 'admin_menu', 'create_custom_meta_box' );
add_action( 'save_post', 'save_custom_post_meta_box', 10, 2 );
function create_custom_meta_box() {
add_meta_box( 'Intro', __('Intro'), 'post_intro_meta_box', 'post', 'normal', 'high' );
}
function save_custom_post_meta_box( $post_id, $post ) {
if ( !current_user_can( 'edit_post', $post_id ) )
return $post_id;
// Custom intro text box (Ingress)
// If custom field does not exists, it is created.
// Then add, update and delete handles are added
/*--------------------------------------------------------------------------- */
if ( !wp_verify_nonce( $_POST['post_intro_meta_box_nonce'], plugin_basename( __FILE__ ) ) )
return $post_id;
// Mini intro
$meta_value = get_post_meta( $post_id, '_post_mini_intro', true );
$new_meta_value = stripslashes( $_POST['post_mini_intro'] );
if ( $new_meta_value && '' == $meta_value )
add_post_meta( $post_id, '_post_mini_intro', $new_meta_value, true );
elseif ( $new_meta_value != $meta_value )
update_post_meta( $post_id, '_post_mini_intro', $new_meta_value );
elseif ( '' == $new_meta_value && $meta_value )
delete_post_meta( $post_id, '_post_mini_intro', $meta_value );
}
