    Hi,

    This is likely a really simple solution but I haven't been able to spot it in the forum posts - I'd appreciate some advice.

    I have a "Tramp Log" CPT which records a history of past tramping trips (hiking trips).

    One of the custom fields when creating a new "Tramp Log" post is the post_title of a tramp listed in the Tramps CPT.

    I want admin users to have the ability to create a new Tramp Log post that pre-populates the name of the Tramp in the new post being created:

    https://example.com/wp-admin/post-new.php?post_type=tramp-log&tramp_name=Example Tramp Name

    Question:

    How can I retrieve the value of the tramp_name URL variable and preapply it to the tramp_name custom field before the create new post page is displayed?

    Thanks in advance!

    Hello Phill,

    You can use the filter hook rwmb_{$field_id}_field_meta to pre-populate value of the field from the URL. For example:

    add_filter( 'rwmb_tramp_name_field_meta', function ( $value, $field, $saved ) {
    $value = isset( $_GET['tramp_name'] ) ? $_GET['tramp_name'] : $value;
    return $value;
}, 10, 3);

    Read more about the filter in the documentation https://docs.metabox.io/filters/rwmb-field-meta/
