Question

a page directs users back to a page automatically

<meta http-equiv="refresh" content="1; URL=http://localhost/mywebsite/Untitled9.php">

when it reaches ‘Untitled9.php’ i want it to display an alert box saying ‘Message sucessfully posted’
I only want it to display when it id directed back to the page and not when first load
e.g Home – Message page = No alert
Home – message page – submit – redirect to message page = alert ‘post sucessfully posted’

Answer 1

Can’t control the DOM of a page externally.

What you could do however is pass a variable in the query string to the page you’re redirecting to like this

Untitled9.php?message=success

Then on your new page have

<?php 
session_start();
if ($_GET['message'] == "success" && $_SESSION['revisit'] == "0")
{
    $_SESSION['revisit'] = "1";
    ?>
    <script type="text/javascript">window.alert('Message successfully posted.');</script>
    <?php
}
?>

In your first page change your code to look like this

<?php
session_start();
$_SESSION['revisit'] = "0";
?>
<meta http-equiv="refresh" content="1; URL=http://localhost/mywebsite/Untitled9.php">
