Hi,

I have some problems rendering an image in CGridView. I have the following code:

$this->widget('zii.widgets.grid.CGridView', array(
	'dataProvider'=>$dataProvider,
	'columns'=>array(

		array(
                  'name'=>'Flag',
                    'type'=>'image',
                    'value'=>'CHtml::image("images/flags/".$data->country.".gif", "country")',
                ),

	),
));

$data->country contains the name of a country from my DB. So I have added the path and the extension of the image. However, the above code renders the following html:

<img alt="" src="<img src="images/flags/England.gif" alt="country" />"/>

I have found a solution to the problem by either declaring

'type'=>'raw',

or

'type'=>'html',

...but would like to know how to use the image type as I would like to use the proper settings of the framework.

Is there a bug in the code that is supposed to render an image or is there a bug in my head that has missed something in the above code making it not work?

Cheers,
b

Edit: The code is supposed to render the flag of the respective country.

What about this?

$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
  'columns'=>array(
    array(
      'name'=>'Flag',
      'type'=>'image',
      'value'=>'images/flags/'.$data->country.'.gif',
    ),
  ),
));

Edit: this should work too

      ...
      'value'=>array('images/flags/'.$data->country.'.gif', 'country'),
      ...

(not tested)

Hi Tommy,

your first code renders an empty <td/>

Your second suggestion returns:

include(images/flags/.gif.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory
Source File

/home/yourownb/framework/YiiBase.php(338)

00326: * @param string class name
00327: * @return boolean whether the class has been loaded successfully
......
00338: include($className.'.php');

Then I don't know right now.

thanks for attempting to help anyway.

It can be done with 'type'=>'image', but CFormatter::formatImage() will only pass one parameter to CHtml::image(), i.e. only url can be specified since CHtml::image doesn't decode an array (which I wrongly assumed).

This should work (url only):

...
'value'=>'"images/flags/'.$data->country.'.gif"',
...

Note the double quotes.

I think it should be:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'name'=>'Flag',
             'type'=>'html',
             'value'=>'CHtml::image("images/flags/".$data->country.".gif", "country")',
        ),
    ),
));

or:

$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        array(
            'name'=>'Flag',
             'type'=>'image',
             'value'=>'"images/flags/" . $data->country . ".gif"',
        ),
    ),
));

When "type" is "image", "value" must be link to the image.

This is not working either. It returns:

<img alt="" src="images/flags/.gif"/>

This has worked excellent:

'value'=>'"images/flags/" . $data->country . ".gif"',

thanks. Looks like the issue was with the formatting as Tommy suggested same strategy but I guess his formatting was incorrect such as mine.

Cheers guys,

Yeah, I should have mentioned that the $data->country was untested. Late hours

You can't with the current implementation. Use type "raw" instead and use 'CHtml::image(...)' as value to create your custom image tag.
