yii2实现分页和带搜索的分页功能

一、模型配置

事例会用到三个models。文章类别表和文章表用gii生成下即可，最后一个是搜索验证模型。其中，只讲下一个联表和搜索验证。其他不用操作。

1.文章表关联

 ?php//...other codehtml' target='_blank'>public function getCate(){ return $this- hasOne(ArticleCate::className(),[ id = cid ? 

2.搜索模型

common/models/search/创建ArticleSearch.php

 ?phpnamespace common/models/search;use Yii;use yii/base/Model;use yii/data/ActiveDataProvider;use common/models/Article;class ArticleSearch extends Article //public $cname;//文章类别名 * @inheritdoc public function rules() return [ [[ cid , created_at , updated_at ], integer ], [[ id , desc , title , cover , content ], safe ], * @inheritdoc public function scenarios() // bypass scenarios() implementation in the parent class return Model::scenarios(); //搜索 public function search($params) $query = Article::find(); // $query- joinWith([ cate //关联文章类别表 // $query- joinWith([ author = function($query) { $query- from([ author = users }]); $dataProvider = new ActiveDataProvider([ query = $query, pagination = [ pageSize = 2, // 从参数的数据中加载过滤条件，并验证 $this- load($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; // 增加过滤条件来调整查询对象 $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、分页使用

方式一

首先在控制器的动作中，创建分页对象并且为其填充数据：

 ?php//other codeuse yii/data/Pagination;public function actionArticlelist() //分页读取类别数据 $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,? 

其次在视图中我们输出的模板为当前页并通过分页对象链接到该页：

 ?phpuse yii/widgets/LinkPager;use yii/helpers/Html;use yii/helpers/Url;//other codeforeach ($models as $model) { // 在这里显示 $model// 显示分页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? 

视图：

 ?phpuse yii/grid/GridView;echo GridView::widget([ dataProvider = $dataProvider, //每列都有搜索框 控制器传过来$searchModel = new ArticleSearch();  // filterModel = $searchModel, layout = {items} p >
三、搜索带分页功能
创建搜索模型（前面己做）
控制传入数据
视图显示控制器代码：
 ?phppublic function actionIndex() $searchModel = new ArticleSearch(); $dataProvider = $searchModel- search(Yii::$app- request- queryParams); return $this- render( index , [ searchModel = $searchModel, dataProvider = $dataProvider,? 
视图：
 ?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) ?  ?= Html::submitButton( Go! , [ class = btn btn-sm btn-primary ]) ?  ?php ActiveForm::end(); ?  ?= GridView::widget([ dataProvider = $dataProvider, layout = {items} p >
