How to extend CButtonColumn

Hi,

I need to extend CButtonColumn to show a dropdown list. While changing the option with this dropdown, I want to call a specific controller action and update the grid via ajax.

I had a look at the CButtonColumn class, and I think it should not be to difficult to write a function, saying "renderDropdown", like "renderButton" in CButtonColumn class.

My questions:

1/ where to put this ? in components, in extensions ?

2/ should this extend directly from CButtonColumn or from parent CGridColumn ?

Any guidance will be highly appreciate.

btw: I’m at the bottom of the php learning curve

My question is very similar to that one

Good to know that it is possible(same thread)

But I’m a bit like sonam in the fourth post

Ok,

I’m trying to extend CGridColumn, as seen in some extensions: example

My code:

<?php


Yii::import('zii.widgets.grid.CGridColumn');


class LTestColumn extends CGridColumn

{


  protected function renderDataCellContent($row,$data)

  {

	echo "toto";

  }


}

Quiet simple

In my view:

<?php  Yii::import('ext.LTestColumn'); ?>

<?php $this->widget('zii.widgets.grid.CGridView', array(

	'id'=>'vol-grid',

	'dataProvider'=>$model->search(),

	'htmlOptions'=>array('class'=>'table table-striped table-condensed'),

	'pagerCssClass'=>'pagination',

	'pager'=>array('htmlOptions'=>array('class'=>'')),

	'filter'=>$model,

	'summaryText'=>'',

	'columns'=>array(

//some colums


		array(

			'class'=>'LTestColumn',


		),

//etc

I’ve got a blank page with no errors … (I’ve tried also to call parent::init() before, but same result.

Commenting the array with my customized (!) class render the grid correctly …

Note that EImageColumn gives me a blank page too

I’ve just installed php-console:

unexpected T_STRING, expecting T_FUNCTION [/www/planches/protected/extensions/EImageColumn.php:20]

Same kind of error with my simple LTestColumn class.

I’ve changed my editor’s settings and it goes better.

An afternoon long for solving this stupid problem
