Get User email info in Custom post meta

You can get the email using this code:

$user = wp_get_current_user();
$email = $user->user_email;

Hi Adrien,

I'm afraid the plugin only supports static value. There's no way to make it understand the dynamic value at the moment.

Run into it and ended up using something like following to be able to have users update their email address in the frontend:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes[] = [
        'title'  => '',
        'id'     => 'edit_user_profile',
        'type'   => 'user',
        'fields' => [
            [
                'id'   => 'first_name',
                'name' => 'First Name',
                'type' => 'text',
            ],
            [
                'id'   => 'last_name',
                'name' => 'Last Name',
                'type' => 'text',
            ],
            [
                'id'   => 'twt_user_email',
                'name' => 'Email',
                'type' => 'email',
                'save_field' => false
            ],
        ],
    ];
    return $meta_boxes;
} );
//hide user profile metabox in backend (otherwise duplicate)
add_filter( 'rwmb_show_edit_user_profile', '__return_false' );
//populate twt_user_email
add_filter('rwmb_twt_user_email_field_meta', function($meta, $field, $saved) {
    $user = wp_get_current_user();
    return $user->user_email;
}, 10, 3);
//update users email upon profile update
add_filter('rwmb_profile_update_user_data', function($data, $config ) {
    $data['user_email'] = sanitize_email($_POST['twt_user_email']);
    return $data;
}, 10, 2);
