How to access the conversation variable from bbcode_attachment_list

[ziggyfish]

Hi,

I am trying to do add certain conditions to view attachments on articles. One of the conditions is whether the visitor has liked the post or not.

I've narrowed where I need to make the change down to the "bbcode_attachment_list", however, I can't seem to access the $conversation variable from this template. After doing some searching the code I need to change is:

includes/vb5/template/bbcode.php

4468                         // Show image attachments first, then nonImage
4469                         $attachments = array_merge($imgAttachments, $nonImgAttachments);
4470                         $attach_url = "filedata/fetch?id=";
4471                         if ($this->renderImmediate)
4472                         {
4473                                 $text .=  vB5_Template::staticRender(
4474                                         'bbcode_attachment_list',
4475                                         array(
4476                                                 'attachments' => $attachments,
4477                                                 'attachurl' => $attach_url,
4478                                         ), false);
4479                         }
4480                         else
4481                         {
4482                                 $text .= vB5_Template_Runtime::includeTemplate(
4483                                         'bbcode_attachment_list',
4484                                         array(
4485                                                 'attachments' => $attachments,
4486                                                 'attachurl' => $attach_url,
4487                                         )
4488                                 );
4489                         }

However, if I upgrade, then I will need to remake the changes. Is there a way to do this properly without having to redo changes each time I upgrade?
