how to get user selected from multiselect checkbox input in yii2? - php

Question

Recently I installed the multiSelect check box extension.
my _form.php looks like this:
<? = $ Form-> field ($ model_detail, 'product_id') ->
widget (MultiSelect :: className (),
['id' => "multiXX",
"options" => ['multiple' => "multiple"],
'data' => $ rows,
'attribute' => 'product_id',
'model' => $ models ,
"clientOptions" =>
[
"includeSelectAllOption" => true, 'numberDisplayed' => 2,
],
]);
How can I extract the data chosen by the user in actionCreate of anther model?
how can I get the options that the user selected?
(I tried the $_post[] and it didn't worked.)

Answer 1

this is the whole form:
div class="customer-order2-form">
<?php $form = ActiveForm::begin(['action' => ['create']]); ?>
<?= $form->field($model, 'customer_name')->textInput(['maxlength' => 255]) ?>
<?= $form->field($model, 'customer_phone')->widget(\yii\widgets\MaskedInput::className(),
[
'mask' => '999-9999999',
'clientOptions' => ['alias' => '972']
]) ?>
<?php /* $form->field($model, 'customer_phone')->textInput(['maxlength' => 255]) **/?>
<?= $form->field($model, 'order_date')->widget(
DatePicker::className(), [
'inline' => false,
// 'template' => '<div class="well well-sm" style="background-color: #fff; width:250px">{input}</div>',
'clientOptions' => [
'autoclose' => true,
'format' => 'yyyy-m-d'
]
]);?>
<?php $model_detail = new OrderDetails2(); /* -------- כאן הוספתי נתונים ממודל
$rows=ArrayHelper::map(ProductFamily::find()->all(), 'id', 'name'); //--- אין צורך בשאילתא, עכשיו גם מציג את מה שנבחר למעלה
?>
<?= $form->field($model_detail, 'product_id')->widget(
MultiSelect::className(), [
'id'=>"multiXX",
"options" => ['multiple'=>"multiple"], // for the actual multiselect
'name' =>'multicheck',
'data' =>$rows,
'attribute' => 'product_id', // if preselected
'model' => $models,
"clientOptions" =>
[
"includeSelectAllOption" => true,
'numberDisplayed' => 2,
],
]);
?>
<?php
echo $form->field($model, 'description')->textarea(['rows' => 6]);
echo /*$form->field($model, 'totalprice')->textInput();*/
$form->field($model, 'totalprice')->widget(MaskMoney::classname(), [
'pluginOptions' => [
'prefix' => '₪ ',
'allowNegative' => false
]
]);
echo $form->field($model, 'status_id')->dropDownList(ArrayHelper::map(Status::find()->select('*')->all(), 'id', 'name'));
?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'יצירה' : 'עדכון', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
what i tried is saving to different table in DB with a default Array,
and it worked.
it looks like this:
public function actionCreate()
{
$model = new CustomerOrder2();
$model_details= new OrderDetails2();
if ($model->load(Yii::$app->request->post()) && $model->save())
{
if (isset($_POST['product_id'])){
$model_details->attributes = $_POST['product_id'];
$model_details->attributes=array();
echo
$model_details->attributes;
}
echo $_POST['description'];
$values = Array('1'=>'1','2'=>'2');
$model_details->attributes = $_POST['product_id'];
$array=$model_details->attributes;
//$data=OrderDetails2::->request->post();
//$values= Array(Yii::$app->request->post()['multiXX']);
//$values=Array($model_details->attributes);
foreach($values as $value)
{
$command = Yii::$app->db->createCommand();
$command->insert('order_details',array('Order_id'=>$model->id,
'product_id'=> $value,
'quantityOrdered'=> '1',
));
$command->execute();
}
return $this->redirect(['view', 'id' => $model->id]);
}
else {
return $this->render('create', [
'model' => $model,
]);
}
}
