It would be desirable to use possibilities of moduls of a forum. If to use SQL - there is a necessity of creation of all authentications...
in editpost.php unit there is a section

PHP Code:

if ($HTTP_POST_VARS['action']=="updatepost") {
....

    if (trim($attachmentaction)=="delete") {
      $attachmentsql=",attachmentid=0";
      $DB_site->query("DELETE FROM attachment WHERE attachmentid=$postinfo[attachmentid]");
      updatethreadcount($threadinfo[threadid]);
    }
... 


How to use the given possibility?
