gridView在view页面中的一些代码详细模板

<?php

use yii\helpers\Html;
use yii\grid\GridView;
use yii\widgets\Pjax;
use frontend\models\Item;
/* @var $this yii\web\View */
/* @var $searchModel frontend\models\ItemSearch */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = 'Items';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="item-index">

    <h1><?= Html::encode($this->title) ?></h1>
    <?php Pjax::begin(); ?>
    <?php // echo $this->render('_search', ['model' => $searchModel]); ?>

    <p>
        <?= Html::a('Create Item', ['create'], ['class' => 'btn btn-success']) ?>
    </p>

    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            [
                'attribute' =>'cate_id',
                'value' => function($model){

                    return Item::get_type_text($model->cate_id);
                },
                //'filter' =>是下拉列表过滤器
                'filter' => Item::get_type(),
            ],
            'name',
            'buy_price',
            'sell_price',
            [
                'attribute' => 'created_at',
                'format'=>['date','php:Y-m-d H:m:s'],
            ],
            [
                'attribute' => 'updated_at',
                'format'=>['date','php:Y-m-d H:m:s'],
            ],
            [
                'attribute' => 'status',
                'value' => function($model){
                    return $model->status == 1?'在售':'停售';
                },
                'filter' => ['停售','在售'],
            ],
            // 'img_url:url',

            [
            'class' => 'yii\grid\ActionColumn',
            ],
        ],
    ]); ?>
    <?php Pjax::end(); ?>
</div>

其中在model中的代码

    public static  function  get_type_text($id){

        $datas = Category::find()->all();

        $datas = ArrayHelper::map($datas, 'cate_id', 'cate_name');

        return  $datas[$id];
    }

    public static  function  get_type(){

        $cat = Category::find()->all();

        $cat = ArrayHelper::map($cat, 'cate_id', 'cate_name');

        return $cat;
    }

在view页面，集合两个数据的column

[
        'label'=>'省市',
        'attribute'=>'province',
        'value'=>function($data){
            return $data->province."-".$data->city;
        }
   ]
