Add support for IMCE as product image field

Hi,
I had the problem that no images would show up in the ubercart catalog view "mysite.com/catalog" & "mysite.com/catalog/[tid]" though showing up everywhere else.
I checked a lot of different solutions, which can be found on the net, but none of them worked. I always just saw "n/a", where the picture was supposed to be.

I finally tracked through the code to find the error in uc_product.module, within the function function uc_product_table().
The statement beginning on line 1323:
if (($field = variable_get('uc_image_'. $node->type, '')) && isset($node->$field) && file_exists($node->{$field}[0]['filepath']))
never validated until I changed
file_exists($node->{$field}[0]['filepath']) into file_exists($_SERVER['DOCUMENT_ROOT'].$node->{$field}[0]['filepath']).
That way, I got the full path of the file.

Afterwards I had the problem, that on line 1325, $image['filepath'] resolved to the full path (/sites/default/files/myfile.jpg), while Imagecache only wanted a filename. I solved this by using preg_split().

$my_filename = preg_split('/\//', $image[$filepath]);
$data['image'] = array('#value' => l(theme('imagecache', 'product_list',$my_filename[(count($my_filename))-1], $image[$alt], $image['title']), 'node/'. $node->nid, array('html' => TRUE)));

My final problem was not using the default Imagecache Field but my custom Imce Image Field.
Imce is not using the variable node->{$field}[0]['filepath'] but it's own node->{$field}[0]['imceimage_path']. My final solution looked as follows (all of the above solutions included):

  foreach ($args as $nid) {
    $data = array();
    $node = node_load($nid);
    if ($enabled['image']) {
      if (module_exists('imagecache')) {

	//Here comes IMCE_Image integration

	$field = variable_get('uc_image_'. $node->type, '');
	if (file_exists($_SERVER['DOCUMENT_ROOT'].$node->{$field}[0]['imceimage_path']))
	{
		$my_filepath = 'imceimage_path';
		$my_alt = 'imceimage_alt';
	}
	else
	{
		$my_filepath = 'filepath';
		$my_alt = 'alt';	
	}
        if (($field = variable_get('uc_image_'. $node->type, '')) && isset($node->$field) && file_exists($_SERVER['DOCUMENT_ROOT'].$node->{$field}[0][$my_filepath])) {
	  $image = $node->{$field}[0];
          $my_filename = preg_split('/\//', $image[$my_filepath]);
	  $data['image'] = array('#value' => l(theme('imagecache', 'product_list', $my_filename[(count($my_filename))-1], $image[$my_alt], $image['title']), 'node/'. $node->nid, array('html' => TRUE)));
        }

Hope I could help some people and thanks for the nice work.
