list variables in associative array

theWalrus

i'm making a very simple redirect script, because a forum i frequent does not allow active links. they don't like the fact that people can see the referring URL, so this will bounce the links off of my server. however, i have a problem.

here's what i have so far:

<?php

if(isset($_GET['url']))
{
	header("Location: " . $_GET['url']);
}
else
{
	echo "<html>\n<head>\n\t<title>active link redirect</title>
		\n\t<link rel=\"stylesheet\" type=\"text/css\" href=\"dev/index.css\">\n";
	echo "</head>\n";
	echo "please supply a URL to forward to via the get variable 'url'.</html>";
}

?>

some of you can probably already tell what the problem is. when i put in a link with a '&' in it, my script will see it as part of my script's variables, and not as part of the url being passed to $_GET['url'].

what i would like to know is a way to make this work. one way i was thinking was to simply add all the other variables that get assigned into another variable along with the url variable, then use that as the header instead of just calling the $_GET variable. any input is appreciated.

Hmm, would urlencode() be of any assistance to you?

 

if(isset($_GET['url']))
{
    $myurl=urlencode($_GET['url']);
    header("Location: " . $myurl);

}
else
{
    echo "<html>\n<head>\n\t<title>active link redirect</title>
        \n\t<link rel=\"stylesheet\" type=\"text/css\" href=\"dev/index.css\">\n";
    echo "</head>\n";
    echo "please supply a URL to forward to via the get variable 'url'.</html>";
}

Dunno for sure, you might check it out....

nope, that still only works for the first variable in the url to be redirected to.

this is what i use

<?
$rdr = $_GET['url'];
if ($rdr = ""){
echo "please use a url...";
}
else{
header("Location: $rdr");
exit;
}
?>

if u get that error where u have to have .$rdr.
use this:

<?
$rdr = $_GET['url'];
if ($rdr = ""){
echo "please use a url...";
}
else{
header("Location: ".$rdr."");
exit;
}
?>

i'm not quite clear on how that's different from what i have...

Well, then, you might try and code it that way and let us know if it works.....

$var1="$_GET['somevar']" . "$_GET['anothervar']";
$url="$_GET['url'];

if (blah) {
     header("location: $url&$var1");
   }

I'm curious to know if it works (not my scrawl, but if you get it to happen with that technique....)
