CGridView filter by year of date - search

Question

Sorry for long text but my problem is long :-) I made grid like this
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
array(
'name'=>'title',
'type'=>'raw',
'value'=>'CHtml::link(CHtml::encode($data->title), $data->url)'
),
array(
'name'=>'create_time',
'type'=>'raw',
'value' => 'Yii::app()->dateFormatter->format("yyyy", $data->create_time)',
),
),
));
and then i want to filtering by date like title filtering, by textfield.
I made controller with code
$model=new Post('search');
if(isset($_GET['Post']))
$model->attributes=$_GET['Post'];
$this->render('admin',array(
'model'=>$model,
));
and search methode in model
public function search()
{
$criteria=new CDbCriteria;
$criteria->compare('title',$this->title,$partialMatch=true);
$criteria->compare('create_time',$this->create_time,$partialMatch=true);
return new CActiveDataProvider('Post', array(
'criteria'=>$criteria,
'sort'=>array(
'defaultOrder'=>'status, update_time DESC',
),
));
}
i don't forget abount rules()
array('title, create_time', 'safe', 'on'=>'search')
I have got two records wiht today's date. Title filtering works fine but when i type '2015' in 'create_time' column filter textfield and press enter i get "no results found".
I tried this:
array(
'name'=>'create_time',
'type'=>'raw',
'value' => 'Yii::app()->dateFormatter->format("dd MMMM yyyy", $data->create_time)',
'filter' => CHtml::listData(Post::model()->findAll(array('order'=>'create_time')), 'create_time', 'create_time'),
),
and it's seems to work but in my database, create_time is integer(11) (required) and listdata values is number not date and represents full date, not only year.
I controller i made array with unique year values from create_time record's values. Outputs array like $rok['2015'] => '2015'
$model_post = new Post;
$wyniki = $model_post::model() -> findAllBySql('SELECT create_time FROM tbl_post');
for($i=0;$i<count($wyniki);$i++)
{
$rok_temp[$i] = Yii::app()->dateFormatter->format("yyyy", $wyniki[$i]->create_time);
$rok[$rok_temp[$i]] = $rok_temp[$i];
}
$rok = array_unique($rok);
I send $rok to view and
array(
'name'=>'create_time',
'type'=>'raw',
'value' => 'Yii::app()->dateFormatter->format("dd MMMM yyyy", $data->create_time)',
'filter' => $rok,
),
and
$criteria->compare('create_time',Yii::app()->dateFormatter->format("yyyy", $this->create_time));
but then i get "no results found" when filtering.
What i made wrong?

Answer 1

Your time is stored as a UNIX timestamp. You therefore have to do some conversion on the input from the filter to change it to UNIX also. First, create a variable to hold the year in your model
class MyModel extends ... {
public $create_year;
}
Then add this variable to your rules:
array('create_year', 'safe', 'on' => 'search')
array('create_year', 'numerical', 'integerOnly' => true)
Next add the conversion rules for the year to your search() i.e
public function search() {
...
if ($this->create_year) {
$criteria->addBetweenCondition('create_time',
strtotime($this->create_year.'-01-01 00:00:00'),
strtotime($this->create_year.'-12-31 23:59:59')
);
}
...
}
Lastly change your filter to a dropdown to reduce invalid entries:
'filter' => CHtml::activeDropDownList(
$model,
'create_year',
array_combine(range(1900, 2099), range(1900, 2099),
array('prompt' => 'Any year')
)
