Yii2 **省市区三级联动(https://github.com/prodcd/yii2-region)
添加到你的composer.json文件
"prodcd/yii2-region": "dev-master"
1、在地区的Model中添加以下方法
public static function getRegion($parentId=0)
{
$result = static::find()->where(['parent_id'=>$parentId])->asArray()->all();
return ArrayHelper::map($result, 'id', 'name');
}
2、在controller中添加以下action
public function actions()
{
$actions=parent::actions();
$actions['get-region']=[
'class'=>\prodcd\region\RegionAction::className(),
'model'=>\app\models\Region::className()
];
return $actions;
}
3、启用urlManager的enablePrettyUrl的,即隐藏index.php
$url=\yii\helpers\Url::toRoute(['get-region']);
echo $form->field($model, 'province')->widget(\prodcd\region\Region::className(),[
'model'=>$model,
'url'=>$url,
'province'=>[
'attribute'=>'province',
'items'=>Region::getRegion(),
'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择省份']
],
'city'=>[
'attribute'=>'city',
'items'=>Region::getRegion($model['province']),
'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择城市']
],
'district'=>[
'attribute'=>'district',
'items'=>Region::getRegion($model['city']),
'options'=>['class'=>'form-control form-control-inline','prompt'=>'选择县/区']
]
]);
province为省份配置,可用的选项可以查看Html::dropdownList。如果不需要县/区,可以把district删除。
