A simple redirect script

northpark

I am writing a simple redirect script that will do the following job.

eg.

http://www.mysite.com/redirect.php?link={any url} will simply go to any url address follow by the ?link=

<?PHP
if ($link == "$link") {$url = "$link";}
header("Location: $url");
exit();
?>

I have test w/ some simply address, like
http://www.google.com
http://www.yahoo.com
etc, the program works; however, for a more complicate web address, eg,
http://www.bestbuy.com/site/olspage.jsp?id=pcat17005&type=page&_requestid=16101

it won't work anymore,

&skuId=6853988&type=product

is being cut off after redirection. Why I have a problem like this? How can i fix it? thanks

you have to [man]urlencode[/man] the information before putting it in a get variable and then [man]urldecode[/man] the information before redirecting to the page.

try this

  if (isset($_GET['link'] ))
	{
	$link=reset(explode('?', $_GET['link'],2));
	$querystring='';
	if(strpos($_SERVER['QUERY_STRING'],'?')!=0)
	$querystring='?'.end(explode('?',$_SERVER['QUERY_STRING'],2));
	header("Location: $link$querystring"); 
	exit();
	}

Sidney. I tried it again and it works. 🙂 thank you

I am still interesting in the urlencode and urldecode method. Anybody?

 $link='http://www.bestbuy.com/site/olspage.jsp?j=1&id=pcat17005&type=page&_requestid=16101';
//$link='HTTP://WWW.GOOGLE.COM';
if(isset($_GET['link']))
header("Location: ".urldecode($_GET['link'])); 
echo '<a href="'.$_SERVER['PHP_SELF'].'?link='.urlencode($link).'">press</a>';
