How to reload the role specific registration form on validation errors?

2 Views

I test a solution for separate registration for different roles and it works very well. But the validation part/function (see bellow) on errors reloads/reuses the generic registration link and not the role specific link, e.g. http://example.com/wp-login.php?action=register instead of http://example.com/wp-login.php?action=register&role=seller. How to avoid this?

The validation function:

add_action('register_post','my_user_fields_validation',10,3);

function my_user_fields_validation($login, $email, $errors) {
    global $firstname, $lastname;
    //get the role to check
    if (isset($_POST['role'])){
        $user_type = $_POST['role'];
    }
    //check the fields according to the role
    if (isset($user_type) && $user_type == "seller"){
    //check sellers fields
        if ($_POST['business_name'] == '') {
            $errors->add('empty_business_name', "<strong>ERROR</strong>: Please Enter in a Business name");
        }
        if ($_POST['business_address'] == '') {
            $errors->add('empty_business_address', "<strong>ERROR</strong>: Please Enter in Business address");
        } 
    }
    if (isset($user_type) && $user_type == "buyer"){
        //check buyers fields
        if ($_POST['buyer_name'] == '') {
            $errors->add('empty_buyer_name', "<strong>ERROR</strong>: Please Enter in a Buyer name");
        }
    }
}

  1. You can either user session or cookies to setup the user for the desired role e.g:

    /**
* register_roles_with_cookies
*/
class register_roles_with_cookies
{

    function __construct($args = array()){
        //create a hidden field for role and extra fields needed
        add_action('register_form',array($this,'add_hidden_role_field'));
        //validate
        add_action('register_post',array($this,'my_user_fields_validation'),10,3);
        //save the role
        add_action('user_register', array($this,'update_role'));
    }

    public function setCookie($name,$val,$time = false){
        if(false === $time)
            $time = time() + (86400 * 7)); // 86400 = 1 day
        setcookie($name,$val,$time);
    }

    public function getCookie($name){
        if (isset($_COOKIE[$name]))
            return $_COOKIE[$name];
        return false;
    }

    public function add_hidden_role_field(){
        $user_type = isset($_GET['role'])? $_GET['role'] : (($this->getCookie('user_role'))? $this->getCookie('user_role'): false);
        if($user_type){
            $this->setCookie('user_role',$user_type);
            echo '<input id="user_role" type="hidden" tabindex="20" size="25" value="'.$user_type.'" name="role"/>';
        }
