Hope this helps I have searched the web far and wide for a solution to this problem. I already know the Yii2 dropdown way is this: , You can also use Html::dropDownList() <?= Html::dropDownList('s_id', null,
ArrayHelper::map(Standard::find()->all(), 's_id', 'name')) ?>

may help you . Finally solved with an unbelievable change. Just changed the first letter of selected to capital ('selected' should be 'Selected'). Here is the code: <?= $form->field($model, 'cat_id')->dropDownList(
ArrayHelper::map(DeviceCats::find()
->where(['is_deleted' => 'no'])->all(),'id','title')
,['options' => [$_GET['cat_id'] => ['Selected'=>'selected']]
, 'prompt' => ' -- Select Category --']) ?>

Get same values in DropDownList yii2
Date : March 29 2020, 07:55 AM
To fix the issue you can do The problem lies in your code. In your actionCreate() you have created three model objects of the same type DevisReduction. $modelDevisReduction1 = new DevisReduction();
$modelDevisReduction2 = new DevisReduction();
$modelDevisReduction3 = new DevisReduction();
<?= $form->field($modelDevisReduction1, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-1'] )->label(false); ?>
<?= $form->field($modelDevisReduction2, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-2'] )->label(false); ?>
<?= $form->field($modelDevisReduction3, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-3'] )->label(false); ?>
<?php
class DevisReductionForm extends yii\base\Model {
public $idReduction1;
public $idReduction2;
public $idReduction3;
public $taux1;
public $taux2;
public $taux3;
/**
* @inheritdoc
*/
public function rules() {
$rules = [
[['idReduction1', 'idReduction1', 'idReduction1', 'taux1', 'taux2', 'taux3'], 'required'],
];
return array_merge($rules, parent::rules());
}
}
public function actionCreate()
{
//create object of custom form model DevisReductionForm given above
$modelDeviceReduction = new DevisReductionForm ();
if ($modelDeviceReduction->load(Yii::$app->request->post())
{
$modelDevisReduction1 = new DevisReduction();
$modelDevisReduction2 = new DevisReduction();
$modelDevisReduction3 = new DevisReduction();
$modelDevisReduction1->idReduction = $modelDeviceReduction->idReduction1
$modelDevisReduction2->idReduction = $modelDeviceReduction->idReduction2
$modelDevisReduction3->idReduction = $modelDeviceReduction->idReduction3
$modelDevisReduction1->taux = $modelDeviceReduction->taux1
$modelDevisReduction2->taux = $modelDeviceReduction->taux2
$modelDevisReduction3->taux = $modelDeviceReduction->taux3
//write other codes
}
else
{
return $this->render('create', [
'modelDeviceReduction ' => $modelDeviceReduction ,
]);
}
}
/* Reduction 1 */
<?= $form->field($modelDeviceReduction, 'idReduction1')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-1'] )->label(false); ?>
<?= $form->field($modelDeviceReduction,'taux1')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-1'])->label(false); ?>
/* Reduction 2 */
<?= $form->field($modelDeviceReduction, 'idReduction2')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-2'] )->label(false); ?>
<?= $form->field($modelDeviceReduction,'taux2')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-2'])->label(false); ?>
/* Reduction 3 */
<?= $form->field($modelDeviceReduction, 'idReduction3')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-3'] )->label(false); ?>
<?= $form->field($modelDeviceReduction,'taux3')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-3'])->label(false); ?>

Capture a value from a dropdownlist where the display dropdownlist is not default

hope this fix your issue You're repopulating the DropDownList for every postback and reloading the page, hence the SelectedValue property value may be different from the posted value. Just put a check against IsPostBack to prevent repopulating DropDownList data on postback: protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
List<ListItem> items = new List<ListItem>();
for (int i = 0; i < 5; i++)
{
items.Add(new ListItem(DateTime.Now.AddDays(i).ToShortDateString(), DateTime.Now.AddDays(i).ToShortDateString()));
}
ddldate.DataSource = items;
ddldate.DataBind();
ddldate.Items[0].Selected = true;
}
}
