I'm new to Yii and this is not my code
When i search something, the results are duplicated, Like
Results:
product1
product1
product2
product2
And I'm sure that the problem is coming from the Controller because i checked the view.
The Controller:
public function actionIndex($q){
$criteria=new CDbCriteria;
$criteria->with=array('cat','postDesc');
$criteria->together=true;
// $criteria->compare('post.pack_type',2);
$criteria->compare('cat.zone','Group',true);
$criteria->compare('postDesc.name',$q,true);
// $criteria->compare('category_id',$id);
$this->pageTitle = "The search resluts for:".$q;
Yii::app()->clientScript->registerMetaTag(Helpers::config('meta_keyword'), 'keywords');
Yii::app()->clientScript->registerMetaTag(Helpers::config('meta_description'), 'description');
$provider=new CActiveDataProvider('PostCategory', array(
'pagination'=>array(
'pageSize'=> Yii::app()->user->getState('pageSize',Yii::app()->params['defaultPageSize']),
),
'criteria'=>$criteria,
'sort' => array(
'defaultOrder' => 't.post_id desc',
),
));
$this->render('index',array(
'dataProvider'=>$provider,
'cat'=>$cat
));
}
public function actionItem($id){
$model=Post::model()->findByPK((int)$id);
$this->pageTitle = $model->desc->name;
Yii::app()->clientScript->registerMetaTag(Helpers::config('meta_keyword'), 'keywords');
Yii::app()->clientScript->registerMetaTag(Helpers::config('meta_description'), 'description');
$images=PostImage::model()->findAll(array('condition'=>'post_id='.$id));
$attrs=PostAttr::model()->findAll(array('condition'=>'post_id='.$id,'order'=>'post_attr_id'));
$media=PostMedia::model()->findAll(array('condition'=>'post_id='.$id));
$this->render('item',array(
//'dataProvider'=>$provider,
'model'=>$model,
'images'=>$images,
'attrs'=>$attrs,
'media'=>$media,
));
}
So I want it to send not two, but one result of every product.
It may happen if your model contains multiple postDesc or cat related records. Solution may differ depending on what result you want to achieve in this situation, but the simplest one is probably group by PostCategory private key field:
$criteria->group = 't.id';

In my Yii web application, having student table for saving student details. I want to student name in alphabetical order when retrieve data from student table.
public function defaultScope() {
return array("order" => "student_firstname");
}
I tried this function, but not working properly.
Please help me.
Thanks in advance.
you can use the defaultOrder property of CSort. For example...
$dataProvider=new CActiveDataProvider('Example', array(
'sort'=>array(
'defaultOrder'=>array(
'student_firstname'=>false
)
)
));
In model's search method for data provider try to set default order, like this:
$dataProvider=new CActiveDataProvider($this, array(
'sort'=>array(
'defaultOrder'=> 'student_firstname ASC'
)
));
In model's search method for data provider try to set default order, like this:
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>Yii::app()->params['defaultPageSize'],
),
'sort'=>array(
'defaultOrder'=>array(
'student_firstname'=>CSort::SORT_ASC
),
),
));
I'm having problem to show data on cgridview using foreign keys.
This is my case, i have table employee(id, username), client(id, username), and transaction(id, employeeId, clientId). employeeId foreign key to employee.id, and clientId is foreign key to client.id. Now, I want to show employee's name and client's name instead of their id on transaction admin.php.
This is my code:
class Transaction extends CActiveRecord
{
public $client_search;
public $employee_search;
public function rules()
{
return array(
.
.
.
array('id, employeeId, clientId, balance, status, date, client_search, employee_search', 'safe', 'on'=>'search'),
);
}
public function relations()
{
return array(
'employee' => array(self::BELONGS_TO, 'Employee', 'employeeId'),
'client' => array(self::BELONGS_TO, 'Client', 'clientId'),
);
}
public function search()
{
$criteria=new CDbCriteria;
$criteria->with = array( 'client', 'employee' );
$criteria->together = true;
$criteria->compare('t.id',$this->id,true);
$criteria->compare('employee.username', $this->employee_search, true );
$criteria->compare('client.username', $this->client_search, true );
$criteria->compare('t.balance',$this->balance,true);
$criteria->compare('t.status',$this->status);
$criteria->compare('t.date',$this->date,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
//the other functions are there, i don't edit it.
}
that is my model/Transaction.php
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'transaction-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
'id',
array(
'header' => 'Employee',
'name' => 'employee_search',
'value' => '$data->employee->username',
),
array(
'header' => 'Client',
'name' => 'client_search',
'value' => '$data->client->username',
),
array(
'class'=>'CButtonColumn',
),
),
));
that is my views/transaction/admin.php.
and this code gave me error Trying to get property of non-object ($data->employee->id marked).
Actually I have succed to show the employee's name instead of employee's id, but, after that I use the same method for the client, and the error appear.
anyone can help me? My method is making public employee_search, add the rules, add the relation, adding $creiteria->with, then change the admin.php. Anyone please help me.
//UPDATE
SOLVED. Its actually my fault. There is an error in the database about the relation (foreign key). My coding is fine.
It's hard to guess without being able to debug your code but here are some things that could help (I'll add more as I can think of them).
It might be because both the default joinType for relations is LEFT OUTER JOIN and maybe you have a Transaction where one of them is null? If you try to access attributes on null object (as opposed to an actual ActiveRecord object), that's precisely the error message you would be seeing.
You could change it by doing:
public function relations()
{
return array(
'employee' => array(self::BELONGS_TO, 'Employee', 'employeeId',array('joinType'=>'INNER JOIN')),
'client' => array(self::BELONGS_TO, 'Client', 'clientId',array('joinType'=>'INNER JOIN')),
);
}
P.S.: INNER JOIN is the same as just JOIN
Not sure if it will help you, but it's worth trying.

is there a parameter that I can use with ClistView to get the commments of a given post_id
<?php $this->widget('zii.widgets.CListView', array(
'dataProvider'=>$dataProvider,
'itemView'=>'_comment',
'template'=>"{items}\n{pager}",
)); ?>
I'd like to add post_id = value in order to only list the comment with the given post_id
I put a search function in my comment model
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('post_id',$this->post_id,true);
return new CActiveDataProvider('Comment', array(
'criteria'=>$criteria,
'sort'=>array(
'defaultOrder'=>'status, create_time DESC',
),
));
}
Thank in advance for your help. I cannot find in the documentation.
I am a newbei in yii, when a person clicks on a category display him all products under that particular category in a gridview
view
productcategory
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'admin-grid',
'dataProvider'=>$model->SelectedCategoryProducts,
'filter'=>$model,
'columns'=>array(
'Name',
'Model',
'Brand',
'Price',
array(
'class'=>'CButtonColumn',
),
),
)); ?>
controller
product
public function actionProductcategory($id)
{
$model= Product::model()->SelectedCategoryProducts($id);
var_dump($model);
$this->render('productcategory',array(
'model'=>$model,'id'=>$id,
));
}
model
product
public function SelectedCategoryProducts($id)
{
$dataProvider=new CActiveDataProvider('Product', array(
'criteria'=>array(
'select'=>'name,model,price,brand',
'condition'=>'category=:category',
'params'=>array(':category'=>$id),
)));
var_dump($dataProvider);
return $dataProvider;
}
CException
Property "CActiveDataProvider.sellerSelectedCategoryProducts" is not defined.
PLEASE HELP! I am losing my mind on this ... not able to display in gridview.
Pass $id to your view file.
$this->render('productcategory',array('model'=>$model,'id'=>$id));
Then pass id to model function in ccgridview function.
'dataProvider'=>$model->SelectedCategoryProducts($id),
Hope this might help
Controller file
public function actionProductcategory($id)
{
$model=new Product;
$this->render('productcategory',array('model'=>$model,
'id'=>$id));
}
In View file
'dataProvider'=>$model->SelectedCategoryProducts($id),
UPDATE 1
'columns'=>array(
'name',
'model',
'brand',
'price',
change them to lowercase which are your original column names
$dataProvider=new CActiveDataProvider('Product', array(
'criteria'=>array(
'select'=>'name,model,price,brand',
'condition'=>'category=:category',
'params'=>array(':category'=>$id),
)));
this can retrieve needed data.... first check that data is perfect ... is it right after that take second step....
I am slowly advancing yii
Not how to apply this:
I have a CGridView which shows me data from 3 related tables
I do it this way (modify the default generated by the crud:
model tabla1
public function search()
{
...
...
...
$criteria=new CDbCriteria;
$criteria->with = array('tabla2','tabla3');
$criteria->together = true;
$criteria->addInCondition('t.idtb1',1,3,5,6,7);
$criteria->compare('idtb2',$this->idtb2);
$criteria->compare('date',$this->date,true);
$criteria->compare('tabla2.codigo',$this->codigo,true);
$criteria->compare('tabla3.description',$this->descrip,true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
The view
...
...
...
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'redeemed-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
array(
'name'=>'codigo',
'value'=>'$data->tabla2->codigo',
),
array(
'name'=>'description',
'value'=>'$data->tabla3->descrip',
),
This shows me everything works perfect.
The problem is that I want to use two more tables that are not related, they are tabla4 and tabla5 and aggregate data from both tables to Cgridview.
as can be done for linking data to table1 to be unrelated to tabla4 and tabla5?
Greetings and thanks
