Question

I am trying this code to check if there is any account with the same e-mail that is send in a new registration.

Why var_dump($arr_user_db); output one result if the value of $email is new in the database?

public function checkUserDatabase($email=null, $id_fb=null) {
        if(!is_null($email) && is_null($id_fb)){
            unset($arr_user_db);
            $arr_user_db = $this->User->find('first', array('conditions' => array('User.email' == $email)));
            var_dump($email); //string '[e-mail]' (length=28)
            var_dump($arr_user_db);//output an account.

        }
 }

Answer 1

            $arr_user_db = $this->User->find('first', array('conditions' => array('User.email' == $email)));

should be:

            $arr_user_db = $this->User->find('first', array('conditions' => array('User.email' => $email)));
