yii2实现分页，带搜索的分页功能示例

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 code//关联public function getCate（）{return $this->hasOne（ArticleCate::className（）,["id" => "cid"]）;}?>

2.搜索模型
common/models/search/创建ArticleSearch.php

<?phpnamespace commonmodelssearch;use Yii;use yiiaseModel;use yiidataActiveDataProvider;use commonmodelsArticle;class ArticleSearch extends Article{//public $cname;//文章类别名/** * @inheritdoc */public function rules（）{return [[["cid","created_at", "updated_at"], "integer"],[["id", "desc","title","cover","content"], "safe"],];}/** * @inheritdoc */public function scenarios（）{// bypass scenarios（） implementation in the parent classreturn Model::scenarios（）;}//搜索public function search（$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 yiidataPagination;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 yiiwidgetsLinkPager;use yiihelpersHtml;use yiihelpersUrl;//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 yiigridGridView;echo GridView::widget（["dataProvider" => $dataProvider,//每列都有搜索框 控制器传过来$searchModel = new ArticleSearch（）; //"filterModel" => $searchModel,"layout"=> "{items}<div class="text-right tooltip-demo">{pager}</div>", "pager"=>[//"options"=>["class"=>"hidden"]//关闭自带分页"firstPageLabel"=>"First","prevPageLabel"=>"Prev","nextPageLabel"=>"Next", "lastPageLabel"=>"Last", ],"columns" => [//["class" => "yiigridSerialColumn"],//序列号从1开始// 数据提供者中所含数据所定义的简单的列// 使用的是模型的列的数据"id","username",["label"=>"文章类别", /*"attribute" => "cid",产生一个a标签,点击可排序*/ "value" => "cate.cname" ],["label"=>"发布日期","format" => ["date", "php:Y-m-d"],"value" => "created_at"],// 更复杂的列数据["label"=>"封面图","format"=>"raw","value"=>function（$m）{ return Html::img（$m->cover,["class" => "img-circle","width" => 30]）;}],["class" => "yiigridDataColumn", //由于是默认类型，可以省略 "value" => function （$data） {return $data->name; // 如果是数组数据则为 $data["name"] ，例如，使用 SqlDataProvider 的情形。},],[ "class" => "yiigridActionColumn", "header" => "操作","template" => "{delete} {update}",//只需要展示删除和更新 /*"headerOptions" => ["width" => "80"],*/ "buttons" => [ "delete" => function（$url, $model, $key）{ return Html::a（"<i class="glyphicon glyphicon-trash"></i> 删除", ["artdel", "id" => $key],["class" => "btn btn-default btn-xs", "data" => ["confirm" => "你确定要删除文章吗？",] ]）; },"update" => function（$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}<div class="text-right tooltip-demo">{pager}</div>","pager"=>[//"options"=>["class"=>"hidden"]//关闭自带分页"firstPageLabel"=>"First","prevPageLabel"=>"Prev","nextPageLabel"=>"Next","lastPageLabel"=>"Last",], //这部分和上面的分页是一样的
