Cactiveform - Can You Disallow Edits Of Certain Ar Fields?

Yii 1.1 General Discussion

Hi folks,

I have had a thorough dig about and I can’t seem to find a way to do this…

It’s pretty simple - I have a system where an XML parser create AR classes based on parsed attributes and saves the class to the DB (providing it passes validation). So, I do not need to be able to create in the CRUD - it will be entered automatically.

Aside from the PK, there are 3 fields, two of which should not be edited manually, and a third that does require editting, and will be populated from CActiveForm::dropDownList. So, in essence, I will not have any of the fields accepting free-hand input.

The dropDownList is easy enough and is already in place (it is fed from an DB reference table). However, I want to know if there is any way to display the other 2 fields as just uneditable text i.e. like a label simply stating the DB value.

Is there any way to do this?

I tried this…




<div class="row">

<?php echo $form->labelEx($model,'field_id'); ?>

<?php echo $model->field_id; ?>

<?php echo $form->error($model,'field_id'); ?>

</div>

… and this seems to work, including AR validation. Is this an appropriate solution?

Dear Friend

We can do something like this on client side.




<?php echo $form->textField($model,'attribute',array('disabled'=>'disabled'));?>

On server side we can do some thing like this.




public function actionUpdate($id)

	{

		$model=$this->loadModel($id);

                $unchagedField1=$model->unchagedField1;

                $unchagedField2=$model->unchagedField2;

		if(isset($_POST['Model']))

		{

			$model->attributes=$_POST['Model'];

                        $model->unchagedField1=$unchagedField1;

                        $model->unchagedField2=$unchagedField2;


			if($model->save())

				$this->redirect(array('view','id'=>$model->id));

		}


		$this->render('update',array(

			'model'=>$model,

		));

	}

I think this will provide dual protection.

I hope I helped a bit.

Regards.

Agree with reply posted by seenivasan.but will add one more solution for it.Make a field as a hidden field on the form.In this way you dont want to write any code inside a controller. :)
