Widget render output implement dynamic include file

Under lib/widget/, create a new file named TestWidget.class.php file:
code
<?php
class Testwidget extends widget{

    public function Render ($data) {return
          $this->renderfile ("Test_page", $data);
    }
Create a new file under lib/widget/test/test_page.html put the code you read from the database into test_page.html.
and then call {: W (' Test ', Array ())} In other templates
this is just a basic example. In a specific project you can dynamically save the code you read from the database into the lib/widget/test/test_page.html. In the call return $this->renderfile ("Test_page", $data);

The W Method of the W (' Test ', Array ())} is defined in the common class function.php
