Zend框架Access數據庫表對象

Question

我無法訪問我的數組是從fetchRow（）返回

控制器：

$user = $this->getUserId(); 
print_r($user->id); // This is where I am not getting the correct value 
public function getUserId() { 
      $auth = Zend_Auth::getInstance(); 
       if ($auth->hasIdentity()) 
        $username = $auth->getIdentity()->username; 

      $users = new Application_Model_DbTable_Users(); 
      $users->getUserId($username); 

      return $users; 

     } 

DB型號：

public function getUserId($username) { 
    $dbAdapter = Zend_Db_Table::getDefaultAdapter(); 
    $username = $dbAdapter->quote($username); 
    $row = $this->fetchAll('username = ' . $username); 
    if($row == NULL){ 
     throw new Exception("Result is null for $username"); 
    } 
    if (!$row) { 
     throw new Exception("Could not find user $username"); 
    }   
    return $row->toArray();  
} 

當我做的print_r （$用戶> ID）;我沒有得到用戶的用戶ID。這些是我在控制器中打印$ user對象時的結果。

Answer 1

首先，在您的控制器中，您返回模型實例而不是getUser執行結果。應該是這樣的：

public function getUserId() { 
     $auth = Zend_Auth::getInstance(); 
      if ($auth->hasIdentity()) 
       $username = $auth->getIdentity()->username; 

     $users = new Application_Model_DbTable_Users(); 

     return $users->getUserId($username); 

} 

然後，在你的模型 - 的getUser返回行而不是行的陣列（有使用fetchall在你的例子）。試試這個方法：

public function getUserId($username) { 
    $dbAdapter = Zend_Db_Table::getDefaultAdapter(); 
    $username = $dbAdapter->quote($username); 
    $row = $this->fetchRow('username = ' . $username); 
    if(!$row){ 
    throw new Exception("Result is null for $username"); 
    } 

    return $row;  
} 

順便說一句，你的函數被調用getUserId，但似乎你正在試圖獲得用戶的結果。所以，函數名應該是getUser。
