DROPDOWN list input values not fetched - php

Question

I get repeatedly the same error. dropdown data is not fetched from the form. I have my code here
this is my controller:ProductController
{<?php
class ProductController extends Controller
{
public function actionCreate()
{
$model=new CreateForm;
// collect user input data
if(isset($_POST['CreateForm']))
{
$model->attributes=$_POST['CreateForm'];
$model->setAttributes($_POST['CreateForm']);
// validate user input and redirect to the previous page if valid
if($model->validate())
{
$product=new Product;
$product->save();
}
else {
echo "Hi";
}
}
// display the login form
$this->render('create',array('model'=>$model));
}
}
?>}
My model:CreateForm
{<?php
class CreateForm extends CFormModel
{
public $product_name;
public $category_name;
public $description;
public function rules()
{
return array(
array('product_name, category_name, description', 'required'),
array('product_name', 'unique', 'className' => 'Product', 'attributeName' => 'product_name', 'message'=>'This product name is already in use'),
);
}
public function attributeLabels()
{
return array(
'product_name'=>'PRODUCT NAME',
'category_name'=>'CATEGORY',
'description'=>'DESCRIPTION'
);
}
}
?>
}
Category
{
<?php
class Category extends CActiveRecord
{
public static function model($className=__CLASS__)
{
return parent::model($className);
}
public function tableName()
{
return 'category';
}
public function attributeLabels()
{
return array(
'category_id'=>'CATEGORY ID',
'category_name'=>'CATEGORY NAME',
);
}
}
?>}
MY view:create.php
{<?php
$this->pageTitle=Yii::app()->name . ' - Create';
$this->breadcrumbs=array(
'Create',
);
?>
<h1>CREATE</h1>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'create-form',
'enableAjaxValidation'=>true,
'enableClientValidation'=>true,
));
?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<div class="row">
<?php echo $form->labelEx($model,'product_name'); ?>
<?php echo $form->textField($model,'product_name'); ?>
<?php echo $form->error($model,'product_name'); ?>
</div>
<div class="row">
<?php
echo $form->labelEx($model,'category_name');
$records = Category::model()->findAll();
$list = CHtml::listData($records, 'category_id', 'category_name');
echo CHtml::DropDownList('category_name', null, $list, array('prompt'=>'select '));
echo $form->error($model,'category_name');
?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'description'); ?></br>
<?php echo $form->textArea($model,'description',array('style' => 'height:100px;width:500px;','maxlength'=>500)); ?>
<?php echo $form->error($model,'description'); ?>
</div>
<div class="row submit">
<?php echo CHtml::submitButton('CREATE'); ?>
</div>
<?php $this->endWidget(); ?>
</div><!-- form -->
}
if I enter all the fields, again it gives an error stating "PLS enter the category"

Answer 1

What you have done is called massive assignment
$model->attributes=$_POST['CreateForm'];
this would not assign all the values and is not safe in handling datas also
the datas would be saved only if they are in safe in the model
you will redeclare the posted data as
$model->attributes=$_POST['CreateForm'];
$model->dropdownname=$_POST['CreateForm']['dropdownname'];
Hope this will help you

Answer 2

I think you change your code of dropdown.
<?php
echo $form->labelEx($model,'category_name');
$records = Category::model()->findAll();
$list = CHtml::listData($records, 'category_id', 'category_name');
echo CHtml::DropDownList('category_name', null, $list, array('prompt'=>'select '));
echo $form->error($model,'category_name');
?>
To
<?php
echo $form->labelEx($model,'category_name');
$records = Category::model()->findAll();
$result = array();
foreach($records as $p) {
$result[p->category_id] = p->category_name ;
}
echo CHtml::activeDropDownList($model, 'category_name', $result);
echo $form->error($model,'category_name');
?>
Now you need to check, either your category id or name is coming or not.
Then you debug your controller file, as in given below.
public function actionCreate()
{
$model=new CreateForm;
// collect user input data
if(isset($_POST['CreateForm']))
{
$model->attributes=$_POST['CreateForm'];
echo $model->category_id ;
exit ; // Finish program here, and drop down will be printed.
$model->setAttributes($_POST['CreateForm']);
// validate user input and redirect to the previous page if valid
if($model->validate())
{
$product=new Product;
$product->save();
}
else {
echo "Hi";
}
} // display the login form
$this->render('create',array('model'=>$model));
}
Hope it help you.
Thanks
