A brief analysis of Yii2 GridView implementation of drop-down search tutorial, yii2gridview
No more nonsense, let me show you the renderings first. If you are still satisfied, please continue reading:
How to implement it specifically? Considering that a data table may have many fields that require drop-down effects, we first implement a method in its model to facilitate subsequent operations
/**
* 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;
}
Then let’s go to the code to see how to implement the drop-down search
<?= 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'),
],
// ......
],
]); ?>
Like this, we have simply implemented two drop-down effects. To implement the filtering function, just add the search conditions for this field in your dataProvider.
