分页(一)

下面介绍一下 Activedataprovider 类分页的使用

use yiidataActiveDataProvider;  这是必须的步骤，因为我们要使用 ActiveDataProvider 类
use commonmodelsUser;

public function actionList()
{
     $model = new User();
     $dataProvider = new ActiveDataProvider([
        "query" => $model->find();
        "pagination => [
                "pagesize" => "10",
         ]
       ]);

      return $this->render("list", ["model" => $model, "dataProvider" => $dataProvider]);
}

view代码
list.php

use yiigridGridView;  这是必须的；


GridView::widget([
         "dataProvider" => $dataProvider,
         "columns" => [
         "attribute"，(attribute为字段的名称，开发时候根据自己的需要进行修改)
         [
               "attribute" => "create_time",
               "format" => ["data", "Y-m-d H:i:s"],
               "options" => ["width" => "200"]
         ]]，
         ["class" => "yiigridActionColumn", "header" => "操作", "headerOptions" => ["width" => "80"]],
]);

分页(二) 

控制器 CommentController 里面的任意一个方法，在这里我的方法是 actionComment();

<?php

use yiidataPagination;
use appmodelsComment;

  public function actionComment(){
       $data = Comment::find()->andWhere(["id" => "10"]);
       $pages = new Pagination(["totalCount" =>＄data->count(), "pageSize" => "2"]);
       $model = $data->offset($pages->offset)->limit($pages->limit)->all();
       
       return $this->render("comment",[
             "model" => $model,
             "pages" => $pages,
       ]);
  }
?>

好的，到这里，控制器部分基本就结束了。我们接续看 view 里面的代码：

Comment.php 文件代码如下所示

<?php

use yiiwidgetsLinkPager;
?>

      foreach($model as $key=>$val)
      {
           遍历数据，省略......
      }

      <?= LinkPager::widget(["pagination" => $pages]); ?>
