YII框架实现排序

YII框架实现排序

用YII2实现批量修改排序功能，如下图

控制器：

/**
     * Lists all CollectionAlbum models.
     * @return mixed
     */
    public function actionIndex($collectionId=0)
    {
        $collection = Collection::findOne($collectionId);
        if(!$collection){
            throw new NotFoundHttpException('The requested page does not exist.');
        }

        $dataProvider = new ActiveDataProvider([
            'query' => $collection->getAlbums(),
            'sort' => [
                'defaultOrder' => [
                    'sort'=>SORT_DESC,
                    'id' => SORT_DESC
                ]
            ],
        ]);

        if (Yii::$app->request->isPost) {
            CollectionAlbum::saveSort(Yii::$app->request->post('ids'),Yii::$app->request->post('sorts'));
        }

        return $this->render('index', [
            'dataProvider' => $dataProvider,
            'collection'=>$collection,
        ]);
    }

模型

    /**
     *保存排序结果
     * @param array $ids 图片ID组成的数组
     * @param array $sorts 排序结果组成的数组
     * */
    public static  function saveSort($ids,$sorts){
        foreach($ids as $k=>$v){
            $album=CollectionAlbum::findOne(intval($v));
            $album->sort = $sorts[intval($k)];
            $album->save(false);
        }
    }

视图

<?php

use yii\helpers\Html;
use yii\grid\GridView;

/* @var $this yii\web\View */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = '藏品图集：'.$collection->title;
$this->params['breadcrumbs'][] = ['label' => '藏品', 'url' => ['collection/index']];
$this->params['breadcrumbs'][] = '藏品图集';

?>
<div class="collection-album-index">

    <p>
        <?= Html::a('添加图片', ['create','collectionId'=>$collection->id], ['class' => 'btn btn-success']) ?>
    </p>
    <?= Html::beginForm(Yii::$app->request->hostInfo.Yii::$app->request->getUrl(),'post')?>
    <?= GridView::widget([
        'dataProvider' => $dataProvider,

        'columns' => [
            [
                'header'=>'排序',
                'class' => yii\grid\Column::className(),
                'content'=>function ($model){
                    return Html::hiddenInput('ids[]',$model->id).Html::textInput('sorts[]',$model->sort,['style'=>'width:45px;','class'=>'form-control']);
                }
            ],
            [
                'header'=>'图片',
                'class' => yii\grid\Column::className(),
                'content'=>function($model){
                    return Html::img($model->img_url.'?imageView2/1/w/100/h/100');
                },
            ],
            'summary',
            'created_at:datetime',
            [
                'attribute'=>'status',
                'value'=>function($model){
                    return $model->getStatusName();
                },
            ],
            ['class' => 'yii\grid\ActionColumn','template'=>'{update} {delete}']
        ],
        'tableOptions'=>['class' => 'table table-striped']
    ]); ?>
    <?= Html::submitButton('更改排序',['class'=>'btn btn-primary'])?>
    <?= Html::endForm()?>
</div>
