问题描述
我已经使列表框依赖于dropDownList，当从dropDownList中选择一个选项为我带来了添加到列表框中的数据列表时，它可以保存单个选项，但是在尝试保存多个选择时会出现问题，我无法保存多个选项，我试图在控制器中添加一个foreach，但是会引发错误。
DropDownList
<?PHP echo $form->field($model,'group_id')->widget(Select2::classname(),[
'data' => $seccion->lgrupo,//I get the group list
'size' => Select2::MEDIUM,'theme' => Select2::THEME_BOOTSTRAP,'options' => [
'placeholder' => '-- '.Yii::t('backend','Select').' --','onchange'=>'
$.post( "lists?id="+$(this).val(),function( data ) {//I get the list of people registered in the group and send it to the listBox
$( "select#assignment-user_id" ).html( data );
});',],'pluginoptions' => [
'allowClear' => true,'addon' => [
'prepend' => [
'content' => Html::icon('building')
],]
]); ?>
列表框
<?PHP echo $form->field($model2,'users_id')->listBox([],['multiple'=>true,'size'=>17]
); ?>
组控制器
public function actionCreate()
{
$model = new Groups();
$model2 = new Assignment();
$seccion = new Group();
if ($model->load(Yii::$app->request->post()) && $model2->load(Yii::$app->request->post())) {
if ($model->save(false)) {
foreach ($model2->users_id as $i => $as) {
$as->assign_group_id = $model->id_group_list;
if ($model2->save()) {
} else {
// error in saving model
}
}
return $this->redirect(['view','id' => $model->id_group]);
}
}
return $this->render('create',[
'model' => $model,'model2' => $model2,'seccion' => $seccion,]);
}

希望您能告诉我我做错了什么。
解决方法
public function actionCreate()
{
$model = new Groups();
$model2 = new Assignment();
$seccion = new Group();
if ($model->load(Yii::$app->request->post()) && $model2->load(Yii::$app->request->post())) {
if ($model->save(false)) {
foreach ($model2->users_id as $user_id) {
$assignmentModel = new Assignment();
$assignmentModel->user_id= $user_id;
$assignmentModel->assign_group_id = $model->id_group_list;
//$assignmentModel->area= ''; //if you want to set some value to these fields
//$assignmentModel->assignment= '';
if ($assignmentModel->save()) {
} else {
// error in saving model
}
}
return $this->redirect(['view','id' => $model->id_group]);
}
}
return $this->render('create',[
'model' => $model,'model2' => $model2,'seccion' => $seccion,]);
}
