form -> model > array

Hi developers

I have dynamic form

and I want show values in form

$sql = $connection->createCommand('select candidad, ...');

		

$result = $sql -> queryAll();

$count = 1;


foreach($result as $row ) {


   $model['candidad_array[' .$count . ']'] = $row["candidad"];

   <?= $form->field($model, 'candidad_array[' .$count . ']'])->textInput() ?>

   ...

   $count = $count + 1;

}

in models I declare

class FormX extends \yii\db\ActiveRecord

{

    /**

     * @inheritdoc

     */

    

    public $candidad_array = array();

    ...

I have error

Setting unknown property: app\models\FormX::candidad_array[1]

Please post full error message along with file name and trace.

I changed code to:

    foreach($result as $i=>$item) {

        echo $form->field($item,"[$i]candidad"); 

    }

and I have error

Call to a member function formName() on array

problem is in this line -> $formName = $model->formName();

I think $result = $sql -> queryAll(); not give all params like $result = app\models\FormX::find()->all(); because for $result = app\models\FormX::find()->all(); work perfect.

Yes, query builder isn’t creating models for you.
