How to use $_GET in multiple page

**devil_vin** · 09-26-2007, 03:30 PM

Hi..guys!I have a 3 different pages here.Ihave submitted some data in the first page and display them in second page by echoing $_GET['x'].However why I can't use back $_GET['x'] to display the same thing in third page?
What might be changed in order value can be displayed in third page?Thanks..

You would need to pass those variables along to the next page in order for it to work. On the second page; where you echo the $_GET['x'], you would need to pass that to the next page in the url like so:

Code:

page.php?x=<?php echo $_GET['x'];?>&amp;next=another_var

Hope this helps.

Thanks.So how can I coded it at here?

Code:

<td>
<?php echo $_GET['selected_date'];?>&amp;next=another_var;?>
</td>

Let said I still have 3 values in second page need to be sent to third page,how can join up with the previous one which passed from first to second page?

**thetestingsite** · 09-26-2007, 04:26 PM

Well; if you are using forms in those pages, you could simply make a hidden field with that name/value pair. Something like so:

Code:

<input type="hidden" name="x" value="<?php echo $_GET['x'];?>">

Hope this helps.

Sorry.It is quite complex for my form because several values need to pass to third page from first and second page?Can you help me to find out where to insert the right code?

reservation.php(first page)

Code:

<?php
include ('dbconn.cfg'); // database configuration file
$connection = @mysql_connect("localhost", "root", "") or die("Cannot connect to server!");
session_start();
//if (isset($_POST['continue'])) {
    //include_once ('reservation2.php');
//}

//$_SESSION['n'] = @$_SESSION['n']+2;
//include('reservation'.$_SESSION['n'].'.php');
?>

<?php
if(!(isset($_SESSION['gmemberid']))){
  $redirectUrl = "http://localhost/www2/loginReq.html";
  print "<script type=\"text/javascript\">";
  print "window.location.href = '$redirectUrl'";
  print "</script>";	
}
?>
