Wrong query??

I have added the following to userinfo.php:

if(isset($HTTP_GET_VARS['usr'])){
  //get UID from database
  $uid_get_query = 'SELECT uid FROM '.$xoopsDB->prefix('users').' WHERE uname='.$HTTP_GET_VARS['usr'];
  $uid_get_result = $xoopsDB->query($uid_get_query);
  while($uid_get = $xoopsDB->fetchArray($uid_get_result))
  {
    $uid = $uid_get[0];
  }
}


It should be possible to goto http://www.yoursite.tld/userinfo.php?usr=uname
to get the profile...

But $uid stays empty (also when the user exists)
What is wrong with this query or what is wrong with the code??

I can't seem to find out why this doesn't work...

Re: Wrong query??

Either use $xoopsDB->fetchArray() and $uid_get['uid']
or $xoopsDB->fetchRow() and $uid_get[0]

Some other things:

$_GET should be used instead of $HTTP_GET_VARS.
The username should be sanitized prior to using it in a query.
The username needs to be in quotes.

$uid = 0;
if (isset($_GET['usr'])){
   $uname_q = MyTextSanitizer::addSlashes($_GET['usr']);
   $result = $xoopsDB->query(
      'SELECT uid FROM ' .$xoopsDB->prefix('users'). " WHERE uname='$uname_q'"
   );
   $row = $xoopsDB->fetchArray($result);
   $xoopsDB->freeRecordSet($result);
   $uid = ($row !== false) ? $row['uid'] : 0;
}
