User Model

//...

public $validate = array(
    "username" => array(
        "alpha-numeric" => array(
            'rule'     => 'alphaNumeric',
            'required' => true,
            'message'  => 'Username must contain only numbers and letters.'                 
        ),
        "between" => array(
            "rule" => array("between", 4, 25),
            "message" => "Username must contain between 4 to 25 characters."
        )
    ),

//...

User Controller

public function index() {
    debug($this->data); // displays values as expected
    debug($this->User->validates()); // always false, unless I remove alphanumeric rule
}

On submit, my form will always validate the username field as false (triggering its corresponding message), no matter what is in the text. The remaining fields are also not validated. If I remove the username validation rules all together, the remaining fields are still not validated. (Form is submitted as though validated)

What am I missing here?

Before manually calling $this->User->validates() , you must call the model's set method and provide the form's data.

public function index() {
    $this->User->set($this->request->data); // Only way the next method will work.
    debug($this->User->validates());
}
