使用表单提交 CGridView Checked 值

2022-01-04 00:00:00 forms php yii

我有一个带有 CCheckBoxColumn 的 CGridView wigdet，如下所示:

I have a CGridView wigdet with CCheckBoxColumn like this:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'class'=>'CCheckBoxColumn',
        ),
        'title',
        ....
    ),
));

问题:如何将选中的值提交给控制器操作?我知道我需要一个表单、提交按钮，但我需要一个明确的说明来放置东西，以便顶部的搜索框出现.

Question: how to submit to controller action the checked values? I understand that I need a form, submit button, but I need a clear explanation where to put things, so that search boxes on the top appear.

提前致谢.

推荐答案

您并不是绝对需要另一种形式.您可以使用附加了附加 javascript 的链接.

You do not absolutely need another form. You can just use a link with additional javascript attached to it.

要获取选中的值，可以调用javascript函数$.fn.yiiGridView.getChecked(containerID,columnID)，参见这里，它返回一个包含 id 的数组.

To get the checked values, you can call the javascript function $.fn.yiiGridView.getChecked(containerID,columnID), see here, it returns an array containing the ids.

在您看来:

<?php
$this->widget('zii.widgets.grid.CGridView', array(
   'id'=>'example-grid-view-id', // the containerID for getChecked
   'dataProvider'=>$dataProvider,
   'columns'=>array(
       array(
           'class'=>'CCheckBoxColumn',
           'id'=>'example-check-boxes' // the columnID for getChecked
       ),
       'title',
       ....
   ),
));
?>
<div id="for-link">
<?php
   echo CHtml::ajaxLink('SomeLink',Yii::app->createUrl('somecontroller/someaction'),
        array(
           'type'=>'POST',
           'data'=>'js:{theIds : $.fn.yiiGridView.getChecked("example-grid-view-id","example-check-boxes").toString()}'
           // pay special attention to how the data is passed here
        )
   );
?>
<div>

在您的控制器中:

...
public function actionSomeaction(){
    if(isset($_POST['theIds'])){
          $arra=explode(',', $_POST['theIds']);
          // now do something with the ids in $arra
          ...
    }
    ...
}
...

你也可以使用 json 字符串，而不是简单的字符串，在我们通过 ajax 传递的数据中(从视图)，但是你会使用 json_decode 而不是 explode()()(在控制器中).此外，最好在使用前验证/清理 ID.

You could also use json string, instead of simple string, in the data we pass by ajax (from the view), but then instead of explode(), you would use json_decode() (in the controller). Also it would be better to validate/sanitize the ids before use.

查看文档 CHtml::ajaxLink 以了解有关 ajax 链接的更多信息.

Check out the documentation for CHtml::ajaxLink to know more about ajax links.

请注意，该示例有点粗糙，因为我还没有检查空数组的已检查 ID.

Note that the example is a little crude, since i haven't put in checks for empty array of checked ids.
