delayed redirect

trung

Hi, I'm a newb.

How do I do a redirect after a short delay? I know this can be done in javascript, but how about PHP?

You can't do it in PHP per se.

You could create a PHP conditional that then displays an HTML construct with a time-delayed META REFRESH construct (10 second delay shown)...

You would insert a real condition where {condition} is

<?php
if (({condition} == {we're staying on this page})) {
?>

<html>
<head><title>Elvis's Homepage</title></head>
<body>

</body>
</html>

<?
} else {
?>

<html>
<head><title>Redirecting you...</title>
<meta http-equiv="refresh" content="10;URL=http://www.elvis.com/elvispage2.php">
</head>
<body>

<b>You are now being redirected to elvispage2.php...</b>

</body>
</html>

<?
}
?>

you could use the [man]sleep[/man] function...


sleep(5); // 5 seconds delay
header("Location: index.php");
exit;

But then you just see a blank page for 5 seconds. I think he wants a "We are now redirecting you..." message to appear for a few seconds, no?

then do like this:


<html>
<head>
<title>Redirecting You...</title>
<meta http-equiv="Refresh" content="5; url=page.php">
</head>

<body>
You are now being redirected...
</body>
</html>

thx!

another quick question:

is there a way to specify a 'target' frame when redirecting using either the meta header http-equiv="refresh" method or the PHP header("Location: index.php") method?

sadly, I'm using frames...

if you run the script in the page thats in the iframe it will redirect within the iframe 🙂

actually, the opposite is true. I'm running the script in a content frame, and I would like the redirect to target the "_top" frame, so that the whole window changes, not just the frame.

Duey

o hmm i dunno target="_top" ? in the meta

i just had spark in my brain ^_ u can use a frame killer its a javascript thing search @ hotscripts.

You can use the header() function to refresh/redirect the page and the sleep() function to delay the script or you could use the refresh timer in the header() function itself.

Method one

<?php ob_start(); ?>

<?php 
// your page, script, or code here
sleep( '5' );
echo 'You will be re-directed in 5 seconds';
header("Location: http://$SERVER_NAME/page.php"); ?>

<?php ob_end_flush(); ?>

Method two

<?php ob_start(); ?>

<?php 
// your page, script, or code here
header("refresh: 5; url=http://$SERVER_NAME/page.php"); 
echo 'You will be re-directed in 5 seconds'; 
?>

<?php ob_end_flush(); ?>

To be sure that you aren't sending anything to the browser prior to the header() command use output buffering with ob_start() and ob_end_flush() -- although ob_end_flush() isn't needed in MOST cases because it is called automatically at the end of script execution by PHP itself when output buffering is turned on either in the php.ini or by calling ob_start()
