    Hi, I want to use hook rwmb_frontend_insert_post_data and rwmb_frontend_update_post_data to modify custom field data in submitted post data. For example, an custom fields, called calorie, whose data type is hidden is stored in a custom table. I tried to use the following code to modify the data of calorie but failed.

    add_filter( 'rwmb_frontend_insert_post_data', function( $data, $config ) {
    // Make sure you work on the correct form.
    if ( 'diet_form' !== $config['id'] ) {
        return $data;
    }

    $data['calorie'] = '100';
    return $data;
}, 10, 2 );

    Is there a trick I'm not aware of?

    Thanks,
    pctsai

    Hi,

    You can use the hook rwmb_frontend_after_process to trigger a function update the data in the custom table. Like this:

    add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    $data = [
        'calorie' => '200',
    ];
    \MetaBox\CustomTable\API::update( $post_id, 'my_custom_table', $data );
}, 10, 2 );

    Remember to activate the new version of MB Custom Table 2.0.0-rc.2 to use the public API. Please get more details here
