Flash Message in YII Framework - yii

Question

After I send the request, I will announce the result to the user via SET FLASH. What is the way to show a message when the user sends a request?
For example when sending a message form : Display -> form is being send and then a flash message is displayed

Answer 1

Check the wiki on the Yii framework website:
http://www.yiiframework.com/wiki/21/how-to-work-with-flash-messages/
In your controller you can put:
Yii::app()->user->setFlash('success', "Form posted!");
In your view you can echo the flash message by:
<?php echo Yii::app()->user->getFlash('success'); ?>
Optionally you can check if a flash message exists by using the hasFlash method, so the code in your view would look like this:
<?php if(Yii::app()->user->hasFlash('success')):?>
<?php echo Yii::app()->user->getFlash('success'); ?>
<?php endif; ?>

Add setFlash in your controller. Something like this:
if($comment->save())
{
Yii::app()->user->setFlash('commentSubmitted','Thank you for your comment.');
$this->refresh();
}
And in your views, display flash message something like this:
<?php if(Yii::app()->user->hasFlash('commentSubmitted')): ?>
<div class="flash-success">
<?php echo Yii::app()->user->getFlash('commentSubmitted'); ?>
</div>
<?php endif; ?>

In your controller you can put:
if(conditions)
Yii::app()->user->setFlash('success', "Success text");
else
Yii::app()->user->setFlash('error', "Error text");
In your view you can echo the flash message by:
<?php
if(Yii::app()->user->hasFlash('success'))
Yii::app()->user->setFlash('success', '<strong>Well done!</strong> '.Yii::app()->user->getFlash('success').'.');
else
Yii::app()->user->setFlash('error', '<strong>Error!</strong> '.Yii::app()->user->getFlash('error').'.');
$this->widget('bootstrap.widgets.TbAlert', array(
'block'=>true, // display a larger alert block?
'fade'=>true, // use transitions?
'closeText'=>'×', // close link text - if set to false, no close link is displayed
'alerts'=>array( // configurations per alert type
'success'=>array('block'=>true, 'fade'=>true, 'closeText'=>'×'), // success, info, warning, error or danger
),
)); ?>
