$var = $var unexpected result

[MarkFL]

Rather than use a db query to get the browsing user's reputation, I would simply use:

PHP Code:

$vbulletin->userinfo['reputation'] 


Thus, your code becomes:

PHP Code:

$RUserMinus = $vbulletin->userinfo['reputation'] - 1; 

$vbulletin->db->query_write("UPDATE user SET reputation=" . $RUserMinus . " WHERE userid=".$vbulletin->userinfo['userid']) or die (mysql_error());
