Script auto redirects?

[maximeke2]

Hi everybody,

 

i'm working on a event page, and registered users can comment on the events. If they posted a comment before, they can edit that comment by clicking a link.

Once you're in that link, you can edit the title & the content. So when they press submit, the scripts checks your information and updates the database.

Now comes the strange part... my scripts redirects automatically back to the previous page, shows the $_SESSION['msg'] var and doesn't update my database.. I should normally stay on that page and not go back..

 

<?php
session_start();
if(!session_is_registered(username))
{
echo "<script>history.back()</script>";
}
if($_GET['id'] == '')
{
echo "<script>history.back()</script>";
}
?>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<script src="scripts/jquery-1.2.6.min.js"></script>
<link href="styleff.css" rel="stylesheet" type="text/css">

<title>Events</title>
<?php
include 'begin.php';
?>

<div id="contentpage">
<center><h1>Events</h1></center>
<?php
$id=$_GET['id'];
list($rightname) = mysql_fetch_row(mysql_query("select username from eventsresponse where id='$id'"));
if($rightname != $_SESSION['username'] && $_SESSION['rank'] < '5')
{
$_SESSION['msg']='You don\'t have the permission to do that';
echo "<script>history.back()</script>";
}
$discr=$_POST['discr'];
$discr = stripslashes($discr);
$discr = str_replace(' ',' ',$discr);
$title = $_POST['title'];
$title = stripslashes($title);
$title = str_replace(' ',' ',$title);
mysql_query("UPDATE eventsresponse SET title = '$title' WHERE id='$id'");

$_SESSION['msg']='Saved!';
?>

 

any help would be welcome  :-\

The function session_is_registered() is deprecated

Try instead.

if($_SESSION['username']

Edited but it still redirects

[fugix]

if($rightname != $_SESSION['username'] && $_SESSION['rank'] < '5')
{
$_SESSION['msg']='You don\'t have the permission to do that';
echo "<script>history.back()</script>";
}

seems that upon loading this page, one of these conditions is being met to store the session and direct back

I'll try that tomorrow,now i'm going to bed

yes, $_SESION['msg'] is used to display a message, in the main file there is a script:

<?php
if($_SESSION['msg'] != '')
{
echo '<div id="message">'.$_SESSION['msg'].'</div><br>';
/* jquery part: */
?>
<script>
$("#message").hide();
$("#message").show("slow");
$("#message").delay(3500).hide("slow");
</script>
<?
$_SESSION['msg']='';
}
?>

 

But.. i deleted all the

echo "<script>history.back()</script>";

and i placed them back one by one, and there's something wrong with this one:

if($_GET['id'] == '')
{
echo "<script>history.back()</script>";
}

if i place this one back, he redirects, even if the statement is false.

 

 

EDIT: I figured it out! On the previous page there was a form, on wich i forgot to add the ?id=<? echo $id; ?>.. So it works now

Thanx!

I would advise to always use long tags. <?php instead of short tags. <? 

To avoid php.ini setting issues on your server. Just a quick tip
