Add More Variable To Uri Of Error Page

Yii 1.1 General Discussion

I want to add more variables to the query string of error page when I throw new CHttpException, ex


http://localhost/site/error?variable1=xyz&variable2=abc

I have searched around, but there isn’t solution for this issue.

Well, have you tried to add arguments to SiteController’s actionError() method?


public function actionError($variable1 = null, $variable2 = null) {

	// ...

}

but how to pass argument from throw new exception to actionError?

Well, some ideas for you:

[list=1][*]Create your own exception class that extends CHttpException for example.

Declare a property for this new class, for example $variables:


class MyHttpException extends CHttpException {

	public $variables = array();

}

Now way you can either override the constructor, by redefining $message parameter to be used as array:


public function __construct($status,$message=null,$code=0)

{

	$this->statusCode=$status;

	if (null !== $message && is_array($message)) {

		$this->variables = $message;

		parent::__construct($this->variables['message'],$code);

	} else {

		parent::__construct($message,$code);

	}

}

or add a fifth construct parameter $variables:


public function __construct($status,$message=null,$code=0,$variables=null)

{

	$this->statusCode=$status;

	if (null !== $variables && is_array($variables)) {

		$this->variables = $variables;

	}

	parent::__construct($message,$code);

}

[*]You can also use session to store the variables.[/list]

Keep mind that I haven’t tested the above code.
