我已經使用來自Kartik的擴展,用於創建依賴下拉菜單,稱爲DepDrop。Yii2 - 如何在操作中顯示選定的值更新?
我的依賴模式Regencies->區 - >村
當創建行動,一切都還好吧,運行水井,但是當更新行動,在兒童下拉不顯示選定值。
這裏我查看代碼:
<?= $form->field($model, 'fk_regencies_id')->dropDownList(ArrayHelper::map(Regencies::find()->all(),'id','name'), ['id'=>'regency_id']);?>
<?= Html::hiddenInput($model->fk_districs_id, $model->fk_districs_id, ['id'=>$model->fk_districs_id]) ?>
<?= $form->field($model, 'fk_districs_id')->widget(DepDrop::classname(), [
'options'=>['id'=>'district-id'],
'pluginOptions'=>[
'depends'=>['regency_id'],
'placeholder'=>'Select...',
'url'=>Url::to(['/calonpegawai/district']),
'params'=>[$model->fk_districs_id]
]
]) ?>
,在這裏我的控制器:
public function actionDistrict() {
$out = [];
if (isset($_POST['depdrop_parents'])) {
$parents = $_POST['depdrop_parents'];
if ($parents != null) {
$regency_id = $parents[0];
$param1 = null;
if (!empty($_POST['depdrop_params'])) {
$params = $_POST['depdrop_params'];
$param1 = $params[0]; // get the value of input-type-1
}
$out = Districts::getDistrictList($regency_id);
//$out[1] = ['id'=>$regency_id, 'name'=>$param1];
$selected = Districts::getDefaultDistrict($param1);
//$selected[1] = ['id'=>$regency_id, 'name'=>$param1];
// the getDefaultSubCat function will query the database
// and return the default sub cat for the cat_id
echo Json::encode(['output'=>$out, 'selected'=>$selected]);
return;
}
}
echo Json::encode(['output'=>'', 'selected'=>'']);
}
我的模型:
public function getDistrictList($regency_id)
{
$data=\backend\models\Districts::find()
->where(['regency_id'=>$regency_id])
->select(['id','name' ])->asArray()->all();
return $data;
}
public function getDefaultDistrict($param1)
{
$data=\backend\models\Districts::find()
->where(['id'=>$param1])
->select(['id','name' ])->asArray()->all();
return $data;
}
你可以發佈檢查員的瀏覽器請求日誌嗎? – meysam
@meysam我已添加圖片,請回復ajax –
這是Yii2調試面板,請發送瀏覽器控制檯的日誌。在Firefox中按Ctrl + Shift + K,在Chrome中按F12顯示控制檯。 – meysam
