1. Model configuration

The example will use three models. The article category table and article table can be generated with gii, and the last one is the search verification model. Among them, we only talk about the next joint table and search verification. No other operations are required.

1. Article table association

<?php
//...other code
//關(guān)聯(lián)
public function getCate(){
    return $this->hasOne(ArticleCate::className(),[&#39;id&#39; => &#39;cid&#39;]);
  }
?>

2. Search model

common/models/search/Create ArticleSearch.php

<?php
 
namespace common\models\search;
 
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use common\models\Article;
 
class ArticleSearch extends Article
{
  //public $cname;//文章類別名
   
  /**
   * @inheritdoc
   */
  public function rules()
  {
    return [
      [[&#39;cid&#39;,&#39;created_at&#39;, &#39;updated_at&#39;], &#39;integer&#39;],
      [[&#39;id&#39;, &#39;desc&#39;,&#39;title&#39;,&#39;cover&#39;,&#39;content&#39;], &#39;safe&#39;],
    ];
  }
 
  /**
   * @inheritdoc
   */
  public function scenarios()
  {
    // bypass scenarios() implementation in the parent class
    return Model::scenarios();
  }
 
  //搜索
  public function search($params)
  {
    $query = Article::find();
    // $query->joinWith([&#39;cate&#39;]);//關(guān)聯(lián)文章類別表
    // $query->joinWith([&#39;author&#39; => function($query) { $query->from([&#39;author&#39; => &#39;users&#39;]); }]);
 
    $dataProvider = new ActiveDataProvider([
      &#39;query&#39; => $query,
      &#39;pagination&#39; => [
        &#39;pageSize&#39; => 2,
      ],
    ]);
    // 從參數(shù)的數(shù)據(jù)中加載過(guò)濾條件，并驗(yàn)證
    $this->load($params);
 
    if (!$this->validate()) {
      // uncomment the following line if you do not want to any records when validation fails
      // $query->where(&#39;0=1&#39;);
      return $dataProvider;
    }
 
    // 增加過(guò)濾條件來(lái)調(diào)整查詢對(duì)象
    $query->andFilterWhere([
      // &#39;cname&#39; => $this->cate.cname,
      &#39;title&#39; => $this->title,
    ]);
 
    $query->andFilterWhere([&#39;like&#39;, &#39;title&#39;, $this->title]);
    //$query->andFilterWhere([&#39;like&#39;, &#39;cate.cname&#39;, $this->cname]) ;
 
    return $dataProvider;
  }
}

2. Paging use

Method 1

First, in the action of the controller, create the paging object and fill it with data :

<?php
//other code
use yii\data\Pagination;
public function actionArticlelist()
  {
    //分頁(yè)讀取類別數(shù)據(jù)
    $model = Article::find()->with(&#39;cate&#39;);
    $pagination = new Pagination([
      &#39;defaultPageSize&#39; => 3,
      &#39;totalCount&#39; => $model->count(),
    ]);
 
    $model = $model->orderBy(&#39;id ASC&#39;)
      ->offset($pagination->offset)
      ->limit($pagination->limit)
      ->all();
 
    return $this->render(&#39;index&#39;, [
      &#39;model&#39; => $model,
      &#39;pagination&#39; => $pagination,
    ]);
  }
?>

Secondly, in the view, the template we output is the current page and is linked to the page through the paging object:

<?php
use yii\widgets\LinkPager;
use yii\helpers\Html;
use yii\helpers\Url;
//other code
foreach ($models as $model) {
  // 在這里顯示 $model
}
 
// 顯示分頁(yè)
echo LinkPager::widget([
  &#39;pagination&#39; => $pagination,
  &#39;firstPageLabel&#39;=>"First",
  &#39;prevPageLabel&#39;=>&#39;Prev&#39;,
  &#39;nextPageLabel&#39;=>&#39;Next&#39;,
  &#39;lastPageLabel&#39;=>&#39;Last&#39;,
]);
?>

Method Two

Controller:

<?php
    $query = Article::find()->with(&#39;cate&#39;);
 
    $provider = new ActiveDataProvider([
      &#39;query&#39; => $query,
      &#39;pagination&#39; => [
        &#39;pageSize&#39; => 3,
      ],
      &#39;sort&#39; => [
        &#39;defaultOrder&#39; => [
          //&#39;created_at&#39; => SORT_DESC,
          //&#39;title&#39; => SORT_ASC,
        ]
      ],
    ]);
    return $this->render(&#39;index&#39;, [
      &#39;model&#39; => $query,
      &#39;dataProvider&#39; => $provider
    ]);
?>

##View:

<?php
use yii\grid\GridView;
echo GridView::widget([
  &#39;dataProvider&#39; => $dataProvider,
  //每列都有搜索框 控制器傳過(guò)來(lái)$searchModel = new ArticleSearch();
  //&#39;filterModel&#39; => $searchModel,
  &#39;layout&#39;=> &#39;{items}<div class="text-right tooltip-demo">{pager}</div>&#39;,
   &#39;pager&#39;=>[
        //&#39;options&#39;=>[&#39;class&#39;=>&#39;hidden&#39;]//關(guān)閉自帶分頁(yè)
        &#39;firstPageLabel&#39;=>"First",
        &#39;prevPageLabel&#39;=>&#39;Prev&#39;,
        &#39;nextPageLabel&#39;=>&#39;Next&#39;,
         &#39;lastPageLabel&#39;=>&#39;Last&#39;,
   ],
  &#39;columns&#39; => [
    //[&#39;class&#39; => &#39;yii\grid\SerialColumn&#39;],//序列號(hào)從1開(kāi)始
    // 數(shù)據(jù)提供者中所含數(shù)據(jù)所定義的簡(jiǎn)單的列
    // 使用的是模型的列的數(shù)據(jù)
    &#39;id&#39;,
    &#39;username&#39;,
    [&#39;label&#39;=>&#39;文章類別&#39;, /*&#39;attribute&#39; => &#39;cid&#39;,產(chǎn)生一個(gè)a標(biāo)簽,點(diǎn)擊可排序*/ &#39;value&#39; => &#39;cate.cname&#39; ],
    [&#39;label&#39;=>&#39;發(fā)布日期&#39;,&#39;format&#39; => [&#39;date&#39;, &#39;php:Y-m-d&#39;],&#39;value&#39; => &#39;created_at&#39;],
    // 更復(fù)雜的列數(shù)據(jù)
    [&#39;label&#39;=>&#39;封面圖&#39;,&#39;format&#39;=>&#39;raw&#39;,&#39;value&#39;=>function($m){
     return Html::img($m->cover,[&#39;class&#39; => &#39;img-circle&#39;,&#39;width&#39; => 30]);
    }],
    [
      &#39;class&#39; => &#39;yii\grid\DataColumn&#39;, //由于是默認(rèn)類型，可以省略
      &#39;value&#39; => function ($data) {
        return $data->name;
        // 如果是數(shù)組數(shù)據(jù)則為 $data[&#39;name&#39;] ，例如，使用
 
SqlDataProvider 的情形。
      },
    ],
    [
     &#39;class&#39; => &#39;yii\grid\ActionColumn&#39;,
     &#39;header&#39; => &#39;操作&#39;,
     &#39;template&#39; => &#39;{delete} {update}&#39;,//只需要展示刪除和更新
     /*&#39;headerOptions&#39; => [&#39;width&#39; => &#39;80&#39;],*/
     &#39;buttons&#39; => [
       &#39;delete&#39; => function($url, $model, $key){
           return Html::a(&#39;<i class="glyphicon glyphicon-trash"></i> 刪除&#39;,
               [&#39;artdel&#39;, &#39;id&#39; => $key],
               [&#39;class&#39; => &#39;btn btn-default btn-xs&#39;,
               &#39;data&#39; => [&#39;confirm&#39; => &#39;你確定要?jiǎng)h除文章嗎？&#39;,]
               ]);
       },
      &#39;update&#39; => function($url, $model, $key){
           return Html::a(&#39;<i class="fa fa-file"></i> 更新&#39;,
              [&#39;artedit&#39;, &#39;id&#39; => $key],
              [&#39;class&#39; => &#39;btn btn-default btn-xs&#39;]);
       },
      ],
     ],
  ],
]);
?>

3. Search with paging function

Create search model (already done before)

Control incoming data

View display controller code:

<?php
public function actionIndex()
{
 $searchModel = new ArticleSearch();
 $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
 
  return $this->render(&#39;index&#39;, [
    &#39;searchModel&#39; => $searchModel,
    &#39;dataProvider&#39; => $dataProvider,
  ]);
 }
?>

View:

<?php $form = ActiveForm::begin([
  &#39;action&#39; => [&#39;index&#39;],
   &#39;method&#39; => &#39;get&#39;,
   &#39;id&#39; => &#39;cateadd-form&#39;,
   &#39;options&#39; => [&#39;class&#39; => &#39;form-horizontal&#39;],
]); ?>
           
<?= $form->field($searchModel, &#39;title&#39;,[
   &#39;options&#39;=>[&#39;class&#39;=>&#39;&#39;],
   &#39;inputOptions&#39; => [&#39;placeholder&#39; => &#39;文章搜索&#39;,&#39;class&#39; => &#39;input-sm form-control&#39;],
])->label(false) ?>
  <?= Html::submitButton(&#39;Go!&#39;, [&#39;class&#39; => &#39;btn btn-sm btn-primary&#39;]) ?>
<?php ActiveForm::end(); ?>
<?= GridView::widget([
          &#39;dataProvider&#39; => $dataProvider,
          &#39;layout&#39;=> &#39;{items}<div class="text-right tooltip-demo">{pager}</div>&#39;,
          &#39;pager&#39;=>[
            //&#39;options&#39;=>[&#39;class&#39;=>&#39;hidden&#39;]//關(guān)閉自帶分頁(yè)
            &#39;firstPageLabel&#39;=>"First",
            &#39;prevPageLabel&#39;=>&#39;Prev&#39;,
            &#39;nextPageLabel&#39;=>&#39;Next&#39;,
            &#39;lastPageLabel&#39;=>&#39;Last&#39;,
          ],
       //這部分和上面的分頁(yè)是一樣的

The above is the entire content of this article. I hope it will be helpful to everyone’s learning. I also hope that everyone will support PHP Chinese. net.
