任何例外

Question

問題自定義錯誤處理程序是，我都按照這個話題http://www.yiiframework.com/doc/guide/1.1/en/topics.error，但是當我在控制器I引發異常（拋出新的異常（「錯誤」）;），警予不路由到我的自定義錯誤控制器並使用系統默認值。如何處理這種例外情況？

Answer 1

您必須使用Yii自己的異常類之一：CException，CDbException或CHttpException。從鏈接你給：http://www.yiiframework.com/doc/guide/1.1/en/topics.error#raising-exceptions

// if post ID is invalid 
throw new CHttpException(404,'The specified post cannot be found.'); 

Answer 2

在從MySQL異常的情況下運行查詢，

$insertCommand = $model->getCommandBuilder()->createSqlCommand($sql,$baseParams+$relParams); 
try { 
     $insertCommand->execute(); 
} catch(CDbException $e) { 
     // Here's a way to get to the error code for the statement in question. 
     // These codes are standardized ANSI SQL "SQLSTATE" error codes. 
     $sqlErrorCode = $insertCommand->pdoStatement->errorCode(); 
     // And to get to the class part of it, simple grab the two first characters. 
     // The class should be the same regardless of DB vendor, while the rest of the code can differ. 
     // For example one particular error was reported by PostgreSQL as 23505 but MySQL only said 23000. 
     $sqlErrorCodeClass = substr($sqlErrorCode, 0, 2); 
}
