login script works for most - but some can't get in - HELP

[blind_sight]

The login script below works for a lot of people, but I am getting a good few who cannot access.  Funny thing is, they are on windows machines with IE browsers and nothing seems unusual about any of them.

 

Can anyone look at this and give me some clue as to why some people are getting a wrong ID / pass error when their details are correct?

 

THANKS

 

if ($action=="login" && $_POST) {

        $info=sql::select("id,siteID,admin","members","where id='".$_POST[id]."' and password='".$_POST[myPassword]."' and deactivated=0");

        if ($info[id][0]) {

                  $_SESSION[id]=$info[id][0];

                  $_SESSION[siteID]=$info[siteID][0];

                  if ($info[admin][0]==1) {

                          $_SESSION[admin]=1;

                  }

echo"<script>location.href='?action=main'</script>";

        } else {

                  $error='<br><br><center><font face="arial" color="red"><b>Wrong ID/Password</b></font></center>

well im pretty sure PHP has nothing to do with what browser you use.

so these people just must have forgotten their passwords

We double checked that   Couldn't it have something to do with sessions?  Or maybe some crazy security setting???

[quickstopman]

hmm that seems plausible

do you they have cookies enabled?

that a horrible guess because i don't know much about internet explorers horrible flaws

try putting quotes around your post values

 

$info=sql::select("id,siteID,admin","members","where id='".$_POST['id']."' and password='".$_POST['myPassword']."' and deactivated=0");
