Connecting Child Posts to a Parent Post Automatically.

Hi,

For example: you have a post Project A and a frontend submission form on that post page, then you want to create a post Entry B when submitting the frontend form and connected to the post Project A automatically.

If yes, you can use this custom code

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    MB_Relationships_API::add( get_queried_object_id(), $post_id, 'your-relationship-ID', $order_from = 1, $order_to = 1 );
}, 10, 2 );

Refer to this topic https://support.metabox.io/topic/auto-relationship-on-form-submission/#post-31334

Hi,

You can create a button with a link to the page that has the frontend form, and pass the Project A post ID to the URL via a custom parameter. Like this

http://your-site.com/frontend-submission-page/?current_post_id=get_queried_object_id()

Then retrieve the project ID via the variable $_GET

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    $project_id = $_GET['current_post_id'];
    if( !empty( $project_id ) ) MB_Relationships_API::add( $project_id, $post_id, 'your-relationship-ID', $order_from = 1, $order_to = 1 );
}, 10, 2 );

Hope that makes sense.

Hi,

You can add the custom PHP code to the file functions.php in the theme/child theme folder or in a custom plugin or use Code Snippets plugin https://wordpress.org/plugins/code-snippets/
