Yeah, you could do that, I wouldn’t say there is a real right or wrong way though. I’ve attached a couple of code fragments as to how I use it. Unfortunately though since I wrote this, I’ve done very little Cake based stuff (new jobs etc.) although I am doing some more soon so want to have another look at this all.

The code fragments are taken from the admin section of my CMS

Controller:

$contain = array(
			'UploadVariant'
		);
 
 
 
 
 
		$this->paginate = array(
							'Upload'=>array(
											'limit' => 20,
											'contain' => array('UploadVariant.variant = "small"'),
											'order' => array('Upload.id' => 'DESC')
							)
		); 
 
		$this->data = $this->paginate($conditions);

Helper:
This just takes creates a thumbnail and opens a full size version.


 
class UploadHelper extends AppHelper {
 
	var $helpers = array('Html', 'Form');
 
	var $uploadModel = 'Upload';
	var $uploadModelVariant = 'UploadVariant';
 
	public function showThumb(&$data, &$sub_data = null, $rel = null){
 
		$str = '';
 
		$dir = WWW_ROOT . $this->getRealDir($data['dir']);
		$web_dir = '/' . $this->getWebDir($data['dir']);
 
 
 
		if(file_exists($dir . DS . $data['filename'])) {
 
 
 
 
			if($data['quick_type'] == 'image'){
 
 
				if(!empty($sub_data['filename'])){
 
 
 
					if(file_exists($dir . DS . $sub_data['filename'])){
 
						$image = $this->Html->image($web_dir . '/' . $sub_data['filename'], array('alt' => '', 'height' => $sub_data['height'], 'height' => $sub_data['height']));
 
						$str .= $this->Html->link($image, $web_dir . '/' . $data['filename'],array('class' => 'thickbox', 'rel' => $rel), false, false);
 
					} else {
 
 
 
					}
				} else {
 
 
				}
 
			} else {
				$str .= $this->Html->link($data['filename'], $web_dir. DS . $data['filename'],array('target' => '_blank'), false, false);
			}
 
		} else {
 
			$str = 'Missing File';
 
		}
 
 
		return $this->output($str);
 
	}
 
	protected function getRealDir($dir){
		$dir = r('\\', DS, $dir);
		$dir = r('/', DS, $dir);
		return $dir;
	}
 
	protected function getWebDir($dir){
		$dir = r('\\', '/', $dir);
		return $dir;
	}
 
 
 
}
 
?>

View:

1	echo $upload->showThumb($var['Upload'], $var['UploadVariant'][0]);

Thinking about it, you would usually know exactly what variant you are after so between the containable behaviour to filter the data and then possibly some use of array_key_exists() in the view you should be able to end up with some very neat code.

Hope this helps.

Sorry, to further my query – do you even query the UploadVariants or just call the images by prepending the variant name to the Upload filename ie:

$html->image(‘thumb.’.$product['Upload'][0]['filename']);

hey there!
thanks for the great example! Could you give a brief example of how you retrieve the variant images for the product? I have managed it, but it seems very long winded and feel I may be missing a trick?
Cheers!

No worries. Slightly odd error though, must be to do with the public modifiers on the class methods or something like that.

It was my fault, my PHP was 4.4… upgrade to 5.2 fix it, thanks

Very weird. I just down loaded the zip file and and installed it and it runs without any problem once I set up the database of course…

Tried to run your demo code, but it fails with

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /app/models/behaviors/je_meio_upload.php on line 135

Can anyone helps me with this?
