Access to the $data variable from buttons in cgridview - php

Question

Is the any way, to access model located in $data variable from CButtonColumn?
Below code is not working.
array(
'class' => 'CButtonColumn',
'template' => '{test}',
'buttons' => array(
'test' => array(
'label' => 'Select',
'click' => 'js:function() { <b>alert($data->_id);</b> return false;}',
),
),
),

Answer 1

It is possible to access visible attributes from jquery:
'click'=>'js:function(){alert("first element in cgridview is"+$(this).parent().parent().children(":nth-child(1)").text());}'

Answer 2

The only field where $data is allowed in CButtonColumn class is url, imageUrl and visible. To pass id to the javascript click event you may place such id in the url and grab it from the DOM. This is very rude hack but easy implementation.
array(
'class' => 'CButtonColumn',
'template' => '{test}',
'buttons' => array(
'test' => array(
'label' => 'Select',
/* set id */
'url' => $data->id,
/* retrieve id from this DOM element (jQuery) */
'click' => 'function() { alert( $(this).attr("href"); return false;}',
),
),
),
If you are looking for a more clear coding you could work in CDataColumn class

Answer 3

It looks like _id is a private variable (according to Yii's coding "standards"). You can not access private variables (and methods) outside of an object. Create a getter-method like this in your model:
public function getId() {
return $this->_id;
}
and then change your code to:
array(
'class' => 'CButtonColumn',
'template' => '{test}',
'buttons' => array(
'test' => array(
'label' => 'Select',
'click' => 'js:function() { alert($data->id); return false;}',
),
),
),

You need to customize the CButtonColumn class. Have a look this post:

Answer 5

You can do that by custom function, as we can derived a $data variable inside it so that we can utilize better php as well as yii itself.
Try like this :
'test' => array(
'label' => 'Select',
'click' => function($data) {
$id = $data->id;
return "js:function() { alert($id); return false;}";
},
),
