Yii，在不使用隐藏字段的情况下设置模型值

Question

I want to set the value of field in my model. The field (source) is in the database but it doesn't have a field on the form to capture the data. I want to set the value the field without creating a hidden form field. Is that possible?

Thanks!

//in controller
public function actionTest()
                {
        $model=new TestForm();
        $src = 'hello';  
        $model->source($src);
        echo $model->source; // hello
        $this->render('_form',array('model'=>$model));    
                }  

The form is then submitted and of course $source is not in the _POST because there is no field to capture $source

However I have set the value of $model->source but this value doesn't seem to persist because it is not saved in the database.

The only way to solve this i have found is to use a hidden field and pass in the value of $source to the form.

Is there a way to set $model->source and for this value to go in the database without going via the form?

Answer 1

If you need to set the value of $source when displaying the form (because e.g. that's when you have the required data in hand) then create a hidden input control. There's nothing wrong about it; you want to persist a non-default value in your model, and a hidden input element is the way to do that.
