[英]Batch update using CGridView
I want to perform a batch update on some records displayed in a CGridView and using CCheckBoxColumn, but it's not working! 我想对CGridView中显示的某些记录和使用CCheckBoxColumn的记录执行批处理更新,但是它不起作用!
Here is an example scenario: 这是一个示例方案:
Consider the table (MySQL): 考虑表(MySQL):
CREATE TABLE IF NOT EXISTS `tb_test` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`description` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
`active` tinyint(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`)
)
Add some rows: 添加一些行:
INSERT INTO `tb_test` (`id`, `description`, `active`) VALUES
(1, 'Test #1', 0),
(2, 'Test #2', 1),
(3, 'Test #3', 0);
Then use Gii to generate defaults Model, Controller and CRUD, ok? 然后使用Gii生成默认的模型,控制器和CRUD,好吗?
Well, after that, I made some changes in the Controller: 好吧,之后,我对Controller进行了一些更改:
// unlock "active" and "ajaxupdate"
public function accessRules()
{
...
array('allow',
'actions'=>array('active','ajaxupdate'),
'users'=>array('*'),
),
...
}
// ...other stuff
// action Active
public function actionActive()
{
$model=new Test('search');
$model->unsetAttributes(); // clear any default values
if(isset($_GET['Test']))
$model->attributes=$_GET['Test'];
$this->render('active',array(
'model'=>$model,
));
}
// action AjaxUpdate
public function actionAjaxUpdate()
{
$check_column = $_POST['check_column'];
print_r($check_column);
}
And, finally, here is the test View: 最后,这是测试视图:
<?php
$form=$this->beginWidget('CActiveForm', array(
'enableAjaxValidation'=>true,
));
$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'test-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'enablePagination'=>false,
'selectableRows'=>2,
'columns'=>array(
array(
'id'=>'check_column',
'class'=>'CCheckBoxColumn',
'value'=>'$data->active',
'checked'=>'$data->active',
),
'id',
'description',
array(
'class'=>'CButtonColumn',
),
),
));
?>
<script>
function reloadGrid(data) {
$.fn.yiiGridView.update('test-grid');
}
</script>
<?php
echo CHtml::ajaxSubmitButton('Update All',array('test/ajaxupdate'), array('success'=>'reloadGrid'));
$this->endWidget();
?>
My objective is to get the values os ALL the check-boxes and perform a batch update on the table, setting the column ACTIVE to true or false. 我的目标是获取所有复选框的值并在表上执行批更新,将ACTIVE列设置为true或false。
But the Yii framework just send to Ajax the marked checks . 但是Yii框架只是将标记的支票发送给Ajax。 Through the Firebug I can see the result like: 通过Firebug,我可以看到如下结果:
Array
(
[0] => 1
[1] => 0
)
Even if I mark all 3 records! 即使我标记了所有3条记录!
Is there a way of getting the values of ALL the check-boxes? 有没有一种方法来获取所有复选框的值?
Thank you! 谢谢!
1st. 1。 Selectable rows should look like this: 可选行应如下所示:
array(
'class' => 'CCheckBoxColumn',
'selectableRows' => '2',
'id'=>'check_column',
'value'=>'$data->active',
'checked'=>'$data->active',
),
2nd. 第2位。 You can pass them by your own, so ajaxButton will look like: 您可以自己传递它们,因此ajaxButton如下所示:
<?php echo CHtml::ajaxButton(Yii::t("app","grid_update"), 'test/ajaxupdate', array(
'type'=>'POST',
'data'=>'js:{ids : $.fn.yiiGridView.getChecked("grid-id-here","check_columns").toString()}',
'success' =>
'js:function (data) {
//do what you need here
}',
), array(
'id' => 'update_btn_'.rand(0,255),
'class' => 'update_btn'
));?>
With this method you will get string, separated with comma with your selected rows. 使用此方法,您将获得字符串,并用逗号分隔所选行。
