算沒有排在電子郵件ID蛋糕PHP基礎

Question

當我在php算沒有行的我做這樣的

$sql=mysql_query("select * from users where username='$email'") or die("select error".mysql_query()); 

    $no_rows=mysql_num_rows($sql); 

但我不知道如何做到這一點的蛋糕PHP和我的數據即將在今年從

[User] => Array 
    (
     [first_name] => arjun 
     [last_name] => tyagi 
     [username] => arjun@gmail.com 
     [phone_no] => 9569908024 
     [mobile_no] => 9569908024 
     [state_id] => 2 
     [location_id] => 15 
     [password] => cffa41a028807034b54b5849d5f4d3ca7532e701 
     [confirm_password] => 12345 
    ) 

Answer 1

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

但實際上是相當有據可查： http://book.cakephp.org/2.0/en/models/retrieving-your-data.html

Answer 2

要獲取的行數（附帶條件），你應該尋找的find('count') function
