【特别推荐】Yii2 GridView的使用方法

 酷酷的超  Yii2  2020-03-27  56  发表评论

Yii2 GridView是实现yii网格视图的小部件,一般用于报表视图的展示。今天,结合DataProvider(ArrayDataProvider以及SqlDataProvider)说一下GridView中的几个Columns(SerialColumn,DataColumn,ActionColumn)。

1. SerialColumn

SerialColumn就是连续的列,主要用于网格的行号,属于自增式的列。用法很简单:

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'], // 连续编号
        // 其他数据列和操作列
    ]
]);

展示结果:

#
1
2

2. DataColumn

DataColumn主要展示数据的,所有跟数据有关的展示基本都在这个Column中实现。因此用法也很多,但是有一条,如果对数据不做处理,那么字段必须是ArrayDataProvider对象的allModels的二维数组的key或者是SqlDataProvider对象sql查询结果二维数组的key。

用法一:表头即字段名,首字母大写

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        'orderNo',   //订单编号
        'username'   // 用户名
    ]
]);

展示结果:

OrderNoUsername
123345698763Test用户
236479547829Joyven

用法二:定义表头并格式化数据

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        'time:date:日期',
        'pv:raw:PV',
        'uv:raw:UV',
    ]
]);

展示结果:

日期PVUV
2016年9月10日85006384
2016年9月9日83786523

用法三:数据过滤,classattributelabelformat均不是必须要的。class默认是yii\grid\DataColumnattribute是指定排序的字段key,一定是dataProvider中提供的数据的key,如果不指定,对于过滤的数据,不能点击表头排序。

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        [
        'value' => function($data) {
            if (isset($data['time'])) {
                return date('Y-m-d', $data['time']);
            }
        },
        'attribute' => 'time', //用于排序,如果不写,不能点击表头排序,非必须
        'label' => '日期', // 自定义表头,非必须
        'format' => 'raw', // 格式方式,非必须
        ],
        'pv:raw:PV',
        [
        'class' => 'yii\grid\DataColumn',
        'value' => function ($data) {
            if (isset($data['orderCr'])) {
                return ($data['orderCr'] * 100) . '%';
            }
        },
        'attribute' => 'orderCr',
        'label' => '下单转化率',
        'format' => 'raw',
    ],
    ]
]);

关于format支持的格式:

format说明参数返回备注
rawFormats the value as is without any formatting. This method simply returns back the parameter without any format.The only exception is a null value which will be formatted using [[nullDisplay]].@param mixed $value the value to be formatted.@return string the formatted result.-

This can be "short", "medium", "long", or "full", which represents a preset format of different lengths.It can also be a custom format as specified in the ICU manual.Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.@return string the formatted result.@throws InvalidParamException if the input value can not be evaluated as a date value. @throws InvalidConfigException if the date format is invalid.

relativetimeFormats the value as the time interval between a date and now in human readable form.This method can be used in three different ways:1. Using a timestamp that is relative to now.2. Using a timestamp that is relative to the $referenceTime.3. Using a DateInterval object.@param integer or string or DateTime or DateInterval $value the value to be formatted.

3. ActionColumn

ActionColumn是对一行数据进行操作的句柄。class指定处理的类,必须。 header指定表头显示,如果不写,默认为空。非必须。 template中默认有三个:{view} {update} {delete},如果需要其他的,自行添加,比如下面添加了{onshelf} {offshelf} {robot}这三个。buttons除了默认的三个可以不写,其他都必须写。

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        [
            'class' => 'yii\grid\ActionColumn',
            'header' => '操作’,
            'template' => '{view} {update} {delete} {onshelf} {offshelf} {robot}',
            'buttons' => [
                'onshelf' => function ($url, $model, $key){
                    return    $model['status'] ? '' : Html::a('<span class="glyphicon glyphicon-ok"></span>',
                        ['item/shelf'],
                        ['title' => '上架商品', 'data' => ['method' => 'post', 'id' => $key, 'type' => 'on'], 'class'=> 'shelf']);
                },
                'offshelf' => function ($url, $model, $key){
                    return    $model['status'] ? Html::a('<span class="glyphicon glyphicon-remove"></span>',
                        ['item/shelf'],
                        ['title' => '下架商品', 'data' => ['method' => 'post', 'id' => $key, 'type' => 'off'], 'class'=> 'shelf']) : '';
                },
                
                'robot' => function ($url, $model, $key){
                    return     Html::a('<span class="glyphicon glyphicon-knight"></span>',
                        ['robot/like', 'id' => $model['pid'] ],
                        ['title' => '自动点赞', 'class' => 'post-autolike', 'data' => ['method' => 'post']]) ;
                },
            ]
        ],
    ],
]);
