Yii 1.1 General Discussion

I want to set new session for storing error notification.

I have trying to sett session using


Yii::app()->sesssion->add('error',CHtml::errorSummary($model));

this way is work, but I don’t sure are this is the correct way for creating session?

so I wanna to get this session to displaying in form action

how to get session back?

and after error session displayed, I want to unset this session, where I can unset this session?

I wanna to using method = "post" in form without a duplicating possible entry if I refresh page after inserted.

thank you for your attention…

For error notifications you can use CWebUser::setFlash().

For example you could do:


Yii::app()->user->setFlash('error', CHtml::errorSummary($model));

and then on the next user request you can test if the flash is set:


if (Yii::app()->user->hasFlash('error'))

{

   echo Yii::app()->user->getFlash('error');

}

A flash message is only available in the current and next user request (means you don’t have to delete the flash after you displayed it).

Regarding sessions, should read this.
