Pass additional parameters to pagination url - yii

Im using CArrayDataProvider for pagination. Now only page numbers are passed in url. I want to pass some more additional attributes. How do I do that? Here is my dataprovider.
$dataProvider = new CArrayDataProvider($arrayData, array(
'keyField'=>'entity_id',
'sort'=>array(
'attributes'=>array('entity_id'),
'defaultOrder'=>array('entity_id' => false),
),
'pagination'=>array(
'pageSize'=>20,
),
));

CPagination takes params. Try adding 'params' => array('foo' => 'bar') in pagination.

The question was how to pass "additional" parameters.
The code of the accepted answer will override your existing $_GET parameters:
'params' => array('foo' => 'bar')
To add "additional" parameters, first add them to existing $_GET parameters:
$pagerparams = $_GET;
$pagerparams['foo'] = 'bar';
$dataProvider = new CActiveDataProvider($this, array(
'pagination'=>array(
'params' => $pagerparams,
),
...
));

Displaying value from join table in Yii CgridView

I have this very simple table in my view and I'm trying to display value from joined table:
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'skills-grid',
'dataProvider'=>$model->searchWithStudentSuccessRate($id),
'template' => '{items}{pager}',
'cssFile'=>Yii::app()->request->baseUrl. '/themes/'. Yii::app()->theme->name.'/css/table.css',
'htmlOptions'=>array('class'=>'datagrid', 'style'=>'width:550px;'),
'columns'=>array(
array(
'name'=>'name',
),
array(
'name' => 'value',
'header' => Yii::t('MainTrans', 'Value'),
'value' => '$data->student_skills->value',
),
array(
'name' => 'successRate',
'header' => Yii::t('MainTrans', 'Success Rate'),
'value' => '$data->successRate."%"',
),
),
));
And this is the search function:
public function searchWithStudentSuccessRate($id)
{
// Warning: Please modify the following code to remove attributes that
// should not be searched.
$criteria=new CDbCriteria;
$criteria->compare('id',$this->id);
$criteria->compare('name',$this->name,true);
$criteria->compare('t.threshold',$this->threshold);
$criteria->with = array('student_skills');
$criteria->together = true;
$criteria->select = array('IFNULL(CASE WHEN ROUND((student_skills.value/t.threshold)*100,0) > 100 THEN 100 ELSE ROUND((student_skills.value/t.threshold)*100,0) END,0) as successRate','*');
$criteria->group = "t.name";
$criteria->condition = 'student_skills.student_id = '.$id;
$criteria->compare('successRate',$this->successRate);
$criteria->compare('student_skills.value',$this->value);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
'pagination'=>array(
'pageSize'=>25,
),
'sort'=>array(
'defaultOrder'=>array(
'successRate'=>CSort::SORT_DESC,
),
'attributes'=>array(
'successRate'=>array(
'asc'=>'successRate',
'desc'=>'successRate DESC',
),
'*',
),
),
));
}
But I get error: "Trying to get property of non-object" when I added value column to my CGridView.
Everything works fine without column value (columns successRate and name are fine). Relation should be fine as well. The error I get means that the value doesn't exist but it should since I did something similar in my other views and there it works.
Can anyone tell what's wrong? I'm sure it's something minor but I'm struggling with this embarrasing problem for a while.
Thanks
It means that in some conditions $data->student_skills is NULL. Try change this:
'value' => '$data->student_skills->value',
to this
'value' => 'empty($data->student_skills) ? null : $data->student_skills->value',

Get images by custom field

I'm trying to display all images that have a certain custom field from the types plugin set to true. It would also work to filter them by post_content or post_excerpt but none of my attempts have worked so far.
<?
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'post_content' => 'foo',
'numberposts' => -1
);
?>
<? print_r(get_posts($args)); ?>
This get's all images allthough only one has the post_content foo. My attempt to use WP_Query failed miserably as well.
Any help is appreciated!
WP_Query method :
$args = array(
'post_type' => 'attachment',
'post_status' => 'inherit',
'meta_query' => array(
array(
'key' => 'color',
'value' => 'blue',
'compare' => 'LIKE',
),
),
);
$query = new WP_Query( $args );
I am presuming that the reason why you failed with WP_Query is due to the following condition.
Codex states : The default WP_Query sets 'post_status'=>'publish', but attachments default to 'post_status'=>'inherit' so you'll need to explicitly set post_status to 'inherit' or 'any' as well.
http://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters
get_posts method :
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'meta_key' => 'custom-field',
'meta_value' => 'custom value',
'numberposts' => -1
);
print_r(get_posts($args));
The only draw back with this method is that the meta_value needs to exactly match what was entered in the custom field. If you still like to use get_posts then use the meta_query as shown in WP_Query example above.

yii CGridView dataprovider and filter

I know we can show a gridview with a model and it's search method and filter the results, but can we make a gridview with another dataprovider and another model like this and filter its results? Does filter needs to be a part of dataprovider?
$attr = Yii::app()->request->getParam($name);
$model = new User('search');
$model->unsetAttributes();
$model->setAttributes($attr);
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $myDataProvider,
'filter' => $model,
'columns' => array(
array(
'name' => 'username',
'type' => 'raw',
'value' => 'CHtml::encode($data->username)'
),
array(
'name' => 'email',
'type' => 'raw',
),
),
));
The above code doesn't work and I need to add a filter on a previously made data provider.
Btw $attr has a valid data, but grid is not filtered.
$model doesn't affect $myDataProvider since the data provider is not obtained using this model.
$model->search() returns a CActiveDataProvider which contains a CDbCriteria instance. Different CDbCriteria can be combined using mergeWith(). So if you would like the data to be filtered using the values from the $model
...
$model->setAttributes($attr);
$newDataProvider=$model->search();
$myDataProvider->criteria->mergeWith($newDataProvider->criteria);
$this->widget('zii.widgets.grid.CGridView', array(
...
Filter does not need to be a part of dataprovider, but data provider needs to take the model into account, if you want to use it for filtering.
The way this is done by default is to create the data provider using search method on your model, which sets conditions of your data provider based on model values, like so:
'dataProvider' => $model->search()
There is nothing preventing you from creating different data provider, for example:
'dataProvider' => $model->createAnotherDataProvider()
And in your User model:
public function createAnotherDataProvider() {
{
// create your second data provider here
// with filtering based on model's attributes, e.g.:
$criteria = new CDbCriteria;
$criteria->compare('someAttribute', $this->someAttribute);
return new CActiveDataProvider('User', array(
'criteria' => $criteria,
));
}

Yii data provider with clist view

i want to search multiple models in Yii application. The search result are displayed in CList view. Need to use dataprovider in list view. So how can i use multiple dataprovider in Clist view?
You cannot make use of multiple dataproviders rather you combine the result in a single dataprovider
Something like this to get you started:
public function actionSearch($q) {
// Sanitize input
$q = strtolower(strip_tags($q));
$q = preg_replace('/[^a-z 0-9 _ \- \']/', '', $q);
$model1 = Model1::model()->findAll('title LIKE "%'.$q.'%"');
$model2 = Model2::model()->findAll('title LIKE "%'.$q.'%"');
$rawData = array_merge($model1, $model2);
$dataProvider = new CArrayDataProvider($rawData, array(
'sort'=>array(
'attributes'=>array(
'datePublished DESC', 'title',
),
),
'pagination'=>array(
'pageSize'=>10,
),
));
$this->render('search', array(
'dataProvider' => $dataProvider,
'query' => $q,
));
}

How to sort the fields from relation table in Yii?

I am trying to implement sorting with Yii list view. I have joined 2 tables named provider_favourite and service_request in list view. And the fields and contents from both tables are listing in the list view. But sorting is working only in provider_favourite table, not from service_request table.How can I sort the fields from service_request table? Iam using csort for sorting. I also tried CGrid view. But the same problem is happening in grid view also ..
Iam using the following code to join
$criteria = new CDbCriteria;
$criteria->select = 'favourite_notes,favourite, favourite_added_date,max_budget,preferred_location,service_name';
$criteria->join = 'LEFT JOIN service_request AS s ON service_request_id = favourite';
$criteria->condition = 'favourite_type = 1';
$sort=new CSort('ProviderFavourite');
// $sort->defaultOrder='s.max_budget ';
$sort->applyOrder($criteria);
$sort->attributes = array(
'max_budget' => 'service_request.max_budget',
'service_name' => 'service_request.service_name',
'favourite_added_date'
);
$type = 2;
$data = new CActiveDataProvider('ProviderFavourite', array('criteria' => $criteria, 'pagination' => array('pageSize' => 4),'sort'=>$sort
));
$this->renderPartial('favourites', array(
'ModelInstance' => ProviderFavourite::model()->findAll($criteria),
'dataProvider' => $data, 'type' => $type, 'sort'=>$sort,
));
and also Iam providing sortable attributes in list view
$this->widget('zii.widgets.CListView', array('dataProvider'=>$dataProvider,'itemView'=>'index_1',
'id'=>'request',
'template' => ' {items}{pager}',
'sortableAttributes'=>array('favourite_notes','max_budget','service_name')
));
If more details needed, I will provide. Thanks in advance
You have to specify attributes property of your $sort instance. By default only fields of $modelClass (ProviderFavourite in your case) are sortable.
I think it could look like this (not tested):
$sort->attributes = array(
'service_name' => array(
'asc' => 's.service_name ASC',
'desc' => 's.service_name DESC'
),
// ...another sortable virtual attributes from service_request table
"*"
);
You should not create a CSort object in $sort. The CActiveDataProvider will already provide you with the right sort object. The way you do it, you apply the sort criteria to $criteria before you configure the sort attributes. That can not work.
You should try a simple setup like this instead:
$data = new CActiveDataProvider('ProviderFavourite', array(
'criteria' => $criteria,
'pagination' => array('pageSize' => 4),
'sort'=> array(
'attributes' => array(
'service_name' => array(
'asc' => 's.service_name ASC',
'desc' => 's.service_name DESC'
),
// ...
),
));
If you need to access the related CSort object (which you usually don't if you use a CGridView or CListView, because they deal with that for you), then you get it via $data->sort.
