mm_forum

When editing a post and attaching a file, the attachment is not correctly connected to the post.

One will only get an "This attachment does not exist" error.

Background (forum version 0.1.7):
Table tx_mmforum_attachments will contain a valid entry for the new attachment that has been generated in method "performAttachmentUpload". Unfortunately, it will contain the invalid "post_id" of 0 and can thus not be found if you later click on the attachment to download it.

It works well during the initial post creation since the "tx_mmforum_postfactory" updates the according row in line 311.

Solution:
tx_mmforum_pi1->post_edit() function has to be extended.

Lines 2738 following contain the "else" statement that is meant to update or insert file attachments to the existing edited post.
Simply adding the following lines at the end of that "else" (after line 2750) will solve the problem:

$updateArray = array(
    'post_id' => $row['uid']
);
$mergedIds = array_merge($attachments,$attachment_ids);                            
if (count($mergedIds) > 1) $where = 'uid='. implode (' OR uid=', $mergedIds);
else $where = 'uid='.$mergedIds[0];
$GLOBALS['TYPO3_DB']->exec_UPDATEquery(
    'tx_mmforum_attachments',
    $where,
    $updateArray
);
