Getting duplicate text values while updating in yii2-dynamic form - yii2

Question

I am using wbraganca
/
yii2-dynamicform. I have created a dynamic form, able to view the data. Now when I try to update it the value of my 1st text box is always the same for each record. Below is my view
Here Slab Names are S-1 to S-4. Now when I try to update them
Above all the slab names are S-1 but the other fields' data is correct.
public function actionUpdate($id)
{
$model = $this->findModel($id);
$modelsTariffSlabs = $this->findModelSlabs($model->id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
$oldIDs = ArrayHelper::map((array)$modelsTariffSlabs, 'id', 'id');
$modelsTariffSlabs = CustomtariffModel::createMultiple(MdcTariffSlabs::classname(), $modelsTariffSlabs);
CustomtariffModel::loadMultiple($modelsTariffSlabs, Yii::$app->request->post());
$deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsTariffSlabs, 'id', 'id')));
// validate all models
$valid = $model->validate();
$valid = CustomtariffModel::validateMultiple($modelsTariffSlabs) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
if (! empty($deletedIDs)) {
MdcTariffSlabs::deleteAll(['id' => $deletedIDs]);
}
foreach ($modelsTariffSlabs as $modelTariffSlabs) {
$modelTariffSlabs->t_id = $model->id;
if (! ($flag = $modelTariffSlabs->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $model->id]);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('update', [
'model' => $model,
'modelsTariffSlabs' => (empty($modelsTariffSlabs)) ? [new MdcTariffSlabs()] : $modelsTariffSlabs
]);
}
protected function findModelSlabs($id)
{
if (($model = MdcTariffSlabs::find()->where(['t_id'=>$id])->all()) !== null) {
return $model;
}
throw new NotFoundHttpException(Yii::t('app', 'The requested page does not exist.'));
}
_form
<div class="container-items"><!-- widgetContainer -->
<?php foreach ($modelsTariffSlabs as $i => $modelTariffSlabs): ?>

</div>
</div><!-- .row -->
</div>
</div>
<?php endforeach; ?>
</div>
How can I show the actual slabs name?

Answer 1

You have to place a check for slab_name. Here is the snip
<div class="col-sm-3">
<?php if ($modelTariffSlabs->isNewRecord) { ?>
<?= $form->field($modelTariffSlabs, "[{$i}]slab_name")->textInput(['readonly'=>true,'value'=>'S-1','maxlength' => 10,"class"=>"form-control js-slab-name"]) ?>
<?php } elseif (!$modelTariffSlabs->isNewRecord) {?>
<?=$form->field($modelTariffSlabs, "[{$i}]slab_name")->textInput(['readonly' => true, 'value' => $modelTariffSlabs->slab_name, 'maxlength' => 10, "class" => "form-control js-slab-name"])?>
<?php }?>
</div>
