YII2-搜索帶分頁，分頁的兩種方式

1.文章表關聯

<?php //...other code //關聯 public function getCate(){ return $this->hasOne(ArticleCate::className(),['id' => 'cid']); } ?> 

2.搜索模型
common/models/search/創建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 $cname;//文章類別名 /** * @inheritdoc */ public function rules() { return [ [['cid','created_at', 'updated_at'], 'integer'], [['id', 'desc','title','cover','content'], 'safe'], ]; } /** * @inheritdoc */ public function scenarios() { // bypass scenarios() implementation in the parent class return Model::scenarios(); } //搜索 public function search($params) { $query = Article::find(); // $query->joinWith(['cate']);//關聯文章類別表 // $query->joinWith(['author' => function($query) { $query->from(['author' => 'users']); }]); $dataProvider = new ActiveDataProvider([ 'query' => $query, 'pagination' => [ 'pageSize' => 2, ], ]); // 從參數的數據中加載過濾條件，並驗證 $this->load($params); if (!$this->validate()) { // uncomment the following line if you do not want to any records when validation fails // $query->where('0=1'); return $dataProvider; } // 增加過濾條件來調整查詢對象 $query->andFilterWhere([ // 'cname' => $this->cate.cname, 'title' => $this->title, ]); $query->andFilterWhere(['like', 'title', $this->title]); //$query->andFilterWhere(['like', 'cate.cname', $this->cname]) ; return $dataProvider; } } 

二、分頁使用
方式一

首先在控制器的動作中，創建分頁對象並且為其填充數據：

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

其次在視圖中我們輸出的模板為當前頁並通過分頁對象鏈接到該頁：

<?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 echo LinkPager::widget([ 'pagination' => $pagination, 'firstPageLabel'=>"First", 'prevPageLabel'=>'Prev', 'nextPageLabel'=>'Next', 'lastPageLabel'=>'Last', ]); ?> 

方式二

控制器：

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

視圖：

<?php
use yii\grid\GridView;
echo GridView::widget([
    'dataProvider' => $dataProvider, //每列都有搜索框 控制器傳過來$searchModel = new ArticleSearch(); //'filterModel' => $searchModel, 'layout'=> '{items}<div class="text-right tooltip-demo">{pager}</div>', 'pager'=>[ //'options'=>['class'=>'hidden']//關閉自帶分頁 'firstPageLabel'=>"First", 'prevPageLabel'=>'Prev', 'nextPageLabel'=>'Next', 'lastPageLabel'=>'Last', ], 'columns' => [ //['class' => 'yii\grid\SerialColumn'],//序列號從1開始 // 數據提供者中所含數據所定義的簡單的列 // 使用的是模型的列的數據 'id', 'username', ['label'=>'文章類別', /*'attribute' => 'cid',產生一個a標簽,點擊可排序*/ 'value' => 'cate.cname' ], ['label'=>'發布日期','format' => ['date', 'php:Y-m-d'],'value' => 'created_at'], // 更復雜的列數據 ['label'=>'封面圖','format'=>'raw','value'=>function($m){ return Html::img($m->cover,['class' => 'img-circle','width' => 30]); }], [ 'class' => 'yii\grid\DataColumn', //由於是默認類型，可以省略 'value' => function ($data) { return $data->name; // 如果是數組數據則為 $data['name'] ，例如，使用 SqlDataProvider 的情形。 }, ], [ 'class' => 'yii\grid\ActionColumn', 'header' => '操作', 'template' => '{delete} {update}',//只需要展示刪除和更新 /*'headerOptions' => ['width' => '80'],*/ 'buttons' => [ 'delete' => function($url, $model, $key){ return Html::a('<i class="glyphicon glyphicon-trash"></i> 刪除', ['artdel', 'id' => $key], ['class' => 'btn btn-default btn-xs', 'data' => ['confirm' => '你確定要刪除文章嗎？',] ]); }, 'update' => function($url, $model, $key){ return Html::a('<i class="fa fa-file"></i> 更新', ['artedit', 'id' => $key], ['class' => 'btn btn-default btn-xs']); }, ], ], ], ]); ?> 

三、搜索帶分頁功能

創建搜索模型（前面己做）

控制傳入數據

視圖顯示
控制器代碼：

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

視圖：

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