浅析Yii2 GridView实现下拉搜索教程,yii2gridview

废话不多说了,先给大家展示下效果图,如果大家还很满意请继续往下阅读:

具体怎么实现喃?考虑到一张数据表要下拉效果的字段可能有很多个,我们先在其model中实现一个方法方便后续操作

/**
* 下拉筛选
* @column string 字段
* @value mix 字段对应的值,不指定则返回字段数组
* @return mix 返回某个值或者数组
*/
public static function dropDown ($column, $value = null)
{
$dropDownList = [
'is_delete'=> [
'0'=>'显示',
'1'=>'删除',
],
'is_hot'=> [
'0'=>'否',
'1'=>'是',
],
//有新的字段要实现下拉规则,可像上面这样进行添加
// ......
];
//根据具体值显示对应的值
if ($value !== null) 
return array_key_exists($column, $dropDownList) ? $dropDownList[$column][$value] : false;
//返回关联数组,用户下拉的filter实现
else
return array_key_exists($column, $dropDownList) ? $dropDownList[$column] : false;
}

然后我们上代码看看具体怎么实现的下拉搜索

<&#63;= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
// ......
[
'attribute' => 'is_hot',
'value' => function ($model) {
return Article::dropDown('is_hot', $model->is_hot);
},
'filter' => Article::dropDown('is_hot'),
],
[
'attribute' => 'is_delete',
'value' => function ($model) {
return Article::dropDown('is_delete', $model->is_delete);
},
'filter' => Article::dropDown('is_delete'),
],
// ......
],
]); &#63;>

像这样,我们就简单地实现了两个下拉效果,要实现筛选功能,在你的dataProvider自定添加该字段的搜索条件即可。
