hi all i’m a noob of this framework and i want to lean how to pass value from a form to another

in the start_1 form i have this code

 <?= Html::label('Color', 'modl', ['class' => 'control-label']) ?>
  <?= Html::textInput("Color", $value, ['id' => 'color', 'class' => 'form-control']) ?>
 <?= Html::submitButton('Go',['Start_2'], ['class' => 'btn btn-success']) ?>

in the controller i have created this action

public function actionStart_2( ){
 $cl=$_POST["color"];
return $this->render('start_2',"cl" => $cl]);

when i render start_2 $cl is always empty?
any solution or simple idea?
tks all

Hi @marcoc,

Your textInput here has a name of Color and a value of $value. So you have to write your controller accordingly.

   $cl = $_POST["Color"];
   return $this->render('start_2', "value" => $cl]);

But usually we don’t do it like this. We use a Model to pass values between the view and the controller.

Please check the following section of the guide.

Sorry, the code has an error.

return $this->render('start_2', ["value" => $cl]);

But, what error do you get?

Can you show us the whole code of your actionStart_2() method?
Probably you are trying to access $_POST when it is not available.

But, IMO, you should read the guide before you try to write on your own.

here the code

 function actionStart_2($bc,$md,$cl,$ts,$mg ){
    if(isset($bc) and  strlen($bc)>1){
    $rmd='';
    $rcl='';
    $rts='';
    $query=new \yii\db\Query(); 
    $query->select(['Modello','Colore','Tessuto'])
      ->from('articoli')  
      ->where(['IDArticolo'=>$bc]);
    $rows=$query->all();
    $command=$query->createCommand();
     $rows= $command->queryAll();
return $this->render('dett', ["mg"=>$mg,"rows"=>$rows]);
 }
else
{    
        $rmd='';
    $rcl='';
    $rts='';
    $query=new \yii\db\Query(); 
    $query->select(['Modello','Colore','Tessuto'])
      ->from('articoli')
            ->distinct()
         ->andFilterWhere(['like','Modello',$md])
            ->andFilterWhere(['like','Colore',$cl]);
            //->orFilterWhere(['like','Tessuto',$ts]);
    $rows=$query->all();
    $command=$query->createCommand();
     $rows= $command->queryAll();
            
     return $this->render('start_2', ["rows"=>$rows,"mg"=>$mg]);
}

if i use java to read the value of the fields i can passing the value but if i use post the data is always empty

Tks for your time
