yiiframe怎么算

Question

我创建了一个名为screen表中的席位。我有booked seats和seats作为列。我想通过一个递增booked seats一个当booked seats和seats相等我想呼应"tickets fulled"。

public function actionfulltickets($id) 
{ 
    $screen1=screen::model()->findByPk($id); 
    $booked+=screen1.booked_seats; 
    if(screen1.seats==screen1.booked_seats) 
    { 
    $info="tickets fulled"; 
    echo cjson::encode($info); 
} 

Answer 1

public function actionfulltickets($id) 
{ 
    $screen1=screen::model()->findByPk($id); 
    // check have avaiable ticket or not. 
    if(screen1->seats==screen1->booked_seats) 
    { 
     $info="tickets fulled"; 
     echo cjson::encode($info); 
    } else { 
     screen1->booked_seats++; 
     screen1->save(); 
     $info="booked successful"; 
     echo cjson::encode($info); 
    } 
} 

希望它可以帮助你。
