Hi again... There is another way
I've been looking around a bit in the code and found a way to make this possible. First I've installed the mod_login by markoehl wich you can find here:
http://www.phpwcms.de/forum/viewtopic.php?t=9696
Here is how it's done:
Add a new row in table _phpwcms_forum
forum_user varchar(100) NULL = Yes Standard=NULL
in /include/inc_front/content/cnt53.article.inc.php
Add the following to row 175
$sql_topic .= "forum_user = '" .$_SESSION["wcs_user_name"] . "'";
and change row 174 to
$sql_topic .= "forum_text = '".aporeplace($content['forum']['topic']['message'])."', ";
change row 297
$CNT_TMP .= html_specialchars($GLOBALS['FE_USER'][$row_t['forum_uid']]['login']).' </span></td>'."\n";
to
$CNT_TMP .= $row_t["forum_user"].' </span></td>'."\n";
Add the following to row 367
$sql_reply .= "forum_user = '".$_SESSION["wcs_user_name"]."'";
and change row 366 to
$sql_reply .= "forum_text = '".aporeplace($content['forum']['reply']['message'])."', ";
change row 485
$CNT_TMP .= html_specialchars($GLOBALS['FE_USER'][$row_t['forum_uid']]['login'])."</td>\n";
to
$CNT_TMP .= $row_f["forum_user"]."</td>\n";
change row 511
$CNT_TMP .= html_specialchars($GLOBALS['FE_USER'][$row_p['forum_uid']]['login'])."</td>\n";
to
$CNT_TMP .= $row_p["forum_user"]."</td>\n";
If you instead want the username (not the users name) use $_SESSION["wcs_user"] instead of $_SESSION["wcs_user_name"]
Good luck!
