This example describes the usage of widgets in yii. Share it with you for your reference. The specific analysis is as follows:

The WIDGET definition is simple. If you create a widget named "testWidget. php" under/protected/widget/test.

To call a view, you need to write the following code:

The Code is as follows:

<? Php
$ This-> beginWidget ('application. widget. test. testWidget ');
?>
//... The main content of the widget may need to be used...
<? Php
$ This-> endWidget ();
?>


TestWidget. php file definition method:

The Code is as follows:

/**
* Test widget
*/
Class testWidget extends CWidget
{
Public function init ()
{
// This method is executed when $ this-> beginWidget () is executed in the view.
// You can query data here
}

Public function run ()
{
// This method is executed when $ this-> endWidget () is executed in the view.
// The rendering attempt can be performed here. Note that the view mentioned here is the widget view.
// Note that the widget view is placed under the views directory at the same level as the widget. For example, the following view will be placed in
/// Protected/widget/test/views/test. php
$ This-> render ('test', array (
'Str' => 'widget view variable ',
));
}
}

I hope this article will help you design PHP programs based on the Yii framework.
