I want to create a widget, here is the steps I made:
- created folder
widgets
in folderprotected
. - created folder
views
in folderwidgets
. - added this in
config/main.php
:'application.widgets.*'
- this is the code of
widgets/Alert.php
:
class AlertWidget extends CWidget
{
public $alert = null;
private $_data = null;
public function init()
{
$s = Yii::app()->session['userId'];
$r = Requests::model()->findAll('idUser='.$s.' and confirm =0 and unconfirm=0 and cancel=0');
$i=0;
foreach($r as $x)
$i++;
if($i<=0)
$alert=null;
else
$alert="(".$i.")";
$this->_data = new CActiveDataProvider($alert);
}
public function run()
{
$this->render('alert', ['data' => $this->_data]);
}
}
- this is the code of
widgets/views/alert.php
:
echo $data;
- this is the code to how I use the widget in a view:
$this->widget('application.widgets.Alert');
finally I got these errors:
( ! ) SCREAM: Error suppression ignored for
( ! ) Fatal error: Cannot redeclare class AlertWidget in C:\wamp\www\mediastore\protected\widgets\Alert.php on line 27
Answer
if you're going to access the widget using $this->widget('application.widgets.Alert');
then, the widget class name should be Alert
(like: public class Alert extends CWidget...
) and the filename should remain Alert.php
