[RESOLVED] Dynamic form Attribute name must contain word characters only

Yii 2.0 General Discussions
1

Hello,
i tried to use yii2 dynamic form (https://github.com/wbraganca/yii2-dynamicform)

but i allways end with this error :

Attribute name must contain word characters only.

looks the problem come from here ($i) inside form

<?= $form->field($modelVmproductvariation, "[{$i}]vmp_regtarif")->textInput(['maxlength' => true]) ?>

or maybe on the model line ? in the widget ?

'model' => $modelsVmproductvariation[0],

If someone has an idea… 2 days i’m stuck with this, looks like i don’t look where i shoud…

How do you load and validate multiple models in controller?

Thank’s for your interest!
so in my controller :

i have those :

use Yii;
use yii\helpers\Url;  
use yii\helpers\ArrayHelper;
use common\models\Vmproducts;
use common\models\Vmproductvariation;
use common\models\VmproductsSearch;
use common\models\files; 
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\web\UploadedFile;  
use yii\filters\VerbFilter;
use yii\filters\AccessControl;

and for now, without work on the saving part , my actionCreate is :

public function actionCreate()
{
    $model = new Vmproducts();
    $modelsVmproductvariation  = [new Vmproductvariation];
    $upload = new Files();
   
    $model->date_creation = date("Y-m-d H:i:s");
    $model->vmproduct_state = 'todo';

   if ($model->load(Yii::$app->request->post())  ) {

        $upload->file_url = UploadedFile::getInstances($upload, 'file_url');
        $title = str_replace(' ', '_', $model->vmproduct_titre);


    if( $model->validate() && $model->save()){ 
        
        if($upload->file_url){
               $upload->saveMyFile($model,'vmproducts',$upload->file_url,$title);        
            }
            
        }
        Yii::$app->getSession()->setFlash('success', Yii::t('app', 'Produit enregistrée'));
        return $this->redirect(['index']);
    }
    else{
 return $this->render('create', [
        'model' => $model,
        'upload'=> $upload,
        'modelsVmproductvariation' => (empty($modelsVmproductvariation)) ? [new Vmproductvariation] : $modelsVmproductvariation
    ]);
        
    }
    
}

Problem resolved… DON’T let any space in the formFIeld array, and everything works

 'formFields' => [
                    'vmp_regtarif',
                    'vmp_promotarif',
                    'vmp_stock',
                    'vmp_poids',
                    'vmp_profondeur',
                    'vmp_largeur',
                    'vmp_hauteur',
                    'vmp_materiau',
                    'vmp_taille',
                    'vmp_type'
                ],
