Add Member Plugin (Custom Fields)

If you are using PMPro Register Helper and PMPro Add Member Admin, then you can have your custom fields added to the add member form by setting an option “addmember”=>true. e.g.

$fields[] = new PMProRH_Field(
        "referral",                     // input name, will also be used as meta key
        "text",                         // type of field
        array(
            "addmember"=>true,
        ));
