I would like to remove the empty or first option of list data value. I have FruitList
model and it has a list, so I need to prevent from users to select all.
But now the problem is the empty option that can let user to select all Fruits, so how can I remove.
This is my code
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'header' => 'Buyer',
'name' => 'Buyer',
'value' => 'customer_name',
'filter' => $fruits
),
array(
'header' => 'Fruits',
'name' => 'fruit_id',
'value' => '$data->Buyers->FruitList->Name',
'filter' => $fruits
),
array(
'class'=>'CButtonColumn',
),
),
));
By default filters for CGridView
renders dropdown with empty option to allow disabling filtering. But you can overwriting this behavior by providing your own dropdown as a filter:
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'columns'=>array(
array(
'header' => 'Buyer',
'name' => 'Buyer',
'value' => 'customer_name',
'filter' => CHtml::activeDropDownList($model, 'customer_name', $fruits),
),
array(
'header' => 'Fruits',
'name' => 'fruit_id',
'value' => '$data->Buyers->FruitList->Name',
'filter' => CHtml::activeDropDownList($model, 'fruit_id', $fruits)
),
array(
'class'=>'CButtonColumn',
),
),
));
Make sure that you set default value for these filters in your model - something like this in your controller:
// ...
$model->fruit_id = FruitList::DEFAULT_ID;
$model->customer_name = FruitList::DEFAULT_ID;
if (isset($_GET['FruitList'])) {
$model->setAttributes($_GET['FruitList']);
}
$dataProvider = $model->search();
// ...
