Title of post is removed after updating the post

Hi netalys,

You probably need to set attribute disabled or readonly for the title field. Please see this blog post to know how to create custom settings for post fields.

Hi Cedric,

To be able to set a custom attribute for title, you need to create a text field and put it in the meta box (which has ID in the shortcode), like this:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title' => 'Your title',
        'id'    => 'your-id',
        'fields' => [
            [
                'title' => 'Post title',
                'id' => 'post_title',
                'disabled' => true,
            ],
            // Other fields here
        ],
    ];
} );

And in your shortcode, don't include the post_fields parameter:

[mb_frontend_form id="your-id"]
