function itweak_upload_comment in iTweak Upload 6.2

Implementation of hook_comment(). Add attachments to the comment on view or preview. Here we intercept attachments from comment_upload.module, and render them ourselves. It is critical to be before comment_upload.module in {system} (lower weight).

Parameters

$comment: Comment object

$op: Operation

File

./itweak_upload.module, line 1287

iTweakUpload - Tweak attachments display and file upload forms.
