[RESOLVED] Variable remains empty - why?

Jon12345

I have a form that submits to itself but I fail to transfer the variable txtkid. Why is that?

<?
session_start();
session_register("sess_kid");
?>

<?

?>
<form name="form1" method="post" action="<? $PHP_SELF; ?>">
  <table width="895" border="0" cellspacing="0" cellpadding="0">
    <tr> 
      <td width="299"><input name="txtkid" type="text" id="txtkid">
        Search Engine</td>
      <td width="199"><input name="txtdate" type="text" id="txtdate2">
        Date</td>
      <td width="198"><input name="txttime" type="text" id="txttime2">
        Time </td>
      <td width="199"><input type="submit" name="Submit" value="Submit"></td>
    </tr>
  </table>  

</form>

i would guess it's because of register_globals, so if it's off you need to use $POST, $GET, $SERVER, $SESSION instead of just $, and don't use session_register() with it off as well... just use $_SESSION['sess_kid'];

<? 
session_start(); 
$_SESSION['sess_kid']; 
?>

<? 
if (!isset($_POST['txtkid'])) { echo "txtkid is not set"; } 
?> 
<form name="form1" method="post" action="<? $_SERVER['PHP_SELF']; ?>"> 
  <table width="895" border="0" cellspacing="0" cellpadding="0"> 
    <tr> 
      <td width="299"><input name="txtkid" type="text" id="txtkid"> 
        Search Engine</td> 
      <td width="199"><input name="txtdate" type="text" id="txtdate2"> 
        Date</td> 
      <td width="198"><input name="txttime" type="text" id="txttime2"> 
        Time </td> 
      <td width="199"><input type="submit" name="Submit" value="Submit"></td> 
    </tr> 
  </table>   

</form>

U propably have register_globals set to off which is good. That means that you cannot access straight with $txtkid, but you need to use $POST['txtkid']. Also $PHP_SELF should be $SERVER['PHP_SELF'] (or actually $_SERVER['SCRIPT_NAME'] to be more secure).

Yes, that did the trick. Thank you!
