PHP Rewrite page Clinkpager sample code sharing

PHP Rewrite Clinkpager instance of the paging device

1. Where are the custom pager classes placed?

There are two places to put,

The first kind is put in the protected/extensions, in the use is import come in, or in config file import come in;

The second is placed in the protected/components, as components exist, do not need import

2, the best way to derive

Class Mypager extends Clinkpager

The entry function is: public functions run (), and when the pager is displayed, run () is called, and the output is displayed in the corresponding position;

Other fully customizable, if you do not know the previous page, next page, home, last, total pages, current page numbers and other information, you can refer to Clinkpager source code, yii/frameworks/web/widgets/pagers/clinkpager.php

3. Call mode

In the corresponding widget in view, define pager's class as a custom pager class name, and refer to:

$this->widget (' Zii.widgets.CListView ', Array (  ' dataprovider ' and ' = ' $dataProvider,  ' itemview ' = ') _ view_t ',  ' pager ' =>array (  ' class ' = ' Mypager ',));
