Problem:
How to automatically generate the options in a user custom field select dropdown from a custom post type

Solution:
You can use the wpt_field_options filter to dynamically fill a select field's options.

It is not documented. Below is some sample code which populates a field called "Choices" with the posts of the custom type "thing".

/**
 * Auto-populate custom User Field
 */
add_filter( 'wpt_field_options', 'tssupp_populate_user_field', 10, 2 );
 
function tssupp_populate_user_field( $current_options, $title_of_field ){
 
    if ( 'Choices' == $title_of_field ) {
 
        $current_options = array();
 
        $args = array(
            'post_type'     =>   'thing',
            'numberposts'   =>   -1
        );
        $posts = get_posts( $args );
 
        foreach ($posts as $key => $post) {
 
            $current_options[] = array(
                '#title'    =>   $post->post_title,
                '#value'    =>   $post->ID
            );
        }
    }
 
    return $current_options;
}

Problem:
How to validate the field with CRED form and check if custom field value already exists.

Solution:
You can use CRED API hook cred_form_validate to validate the field value and check if field value already exists in database.

You can find proposed solution, in this case, with the following reply:
