How to retain checkbox value when the screen reload?

Yii 1.1 General Discussion

I have been following this example




<div>

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

<?php echo $form->dropDownList($model, 'categories', CHtml::listData(

Categories::model()->findAll(), 'id', 'category'), array('multiple'=>'multiple', 'size'=>5)

); ?>

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

</div>

But when the form is submitted with validation error, all my checkboxes ticks are gone. The rest of the input values persist.

What did I do wrong?

thanks!

Im confused are we talking about checkbox? or dropdownlist?

Can you show me whats the output of print_r($model->categories) before and after the validation please?

I followed the example by Larry exactly except that I use checkBoxList and not dropdownlist.

if the form has no errors, I have no problem getting the values with :




     foreach ($_POST['Posts']['categories'] as $categoryId) {

                $postCategory = new PostsCategories;

                $postCategory->postId = $model->id;

                $postCategory->categoryId = $categoryId;

                if (!$postCategory->save()) print_r($postCategory->errors);

            }

The problem is how to retain the user checkboxes before reached the db.

print_r($model->categories) will give an empty array when the form is reloaded upon validation error.

Thanks

Company Controller




    public function actionCreate()

    {

        $model=new Company;

        $modelPort=Port::model()->findAll();


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

        {

            $model->setAttributes($_POST['Company']);

            if($model->save())

            {

                foreach ($_POST['Company']['ports'] as $portId) {

                    $companyPort = new CompanyPort;

                    $companyPort->companyId = $model->id;

                    $companyPort->portId = $portId;

                    if (!$companyPort->save()) print_r($companyPort->errors);

                }

                $this->redirect(array('list'));

            }

        }

        

        $this->render('create',

                compact('model', 'modelPort'));

    }
