Yii alert widget

In view I have widget:

if ($content):
        echo Alert::widget([
            'options' => [
                'class' => 'alert-info',
            ],
            'body' => $content,
        ]);
endif;

That widget I want render not always, for example after save and atc. Now Now I have placed that widget between if condition, maybe exists some more clear way to render widget only in some cases.

Solution

  • I think Flash-Messages is what you want:

    For Example:
    In the controller you can do something like that:

    <?php
Yii::app()->user->setFlash('success', "Data saved!");
$this->redirect(array('thing/view', 'id' => 1));

    And in the view:

    <?php if(Yii::app()->user->hasFlash('success')):?>
<div class="info">
    <?php echo Yii::app()->user->getFlash('success'); ?>
</div>
<?php endif; ?>

    And of course you can combine it with the alert-widget or with a custom-widget.
