How to pass URL in URL (as GET parameter) using PHP?

Question

I'm having some problems passing URL's as GET parameter. When I try to access:

http://www.linkebuy.com.br/linkebuy/parceiro?url=http%3A%2F%2Fwww.google.com

I get the following message:

Unexpected error.

However, if I go for:

http://www.linkebuy.com.br/linkebuy/parceiro?url=123

Everything works just fine (it redirects to an inexistent site - 123 -, of course, but it does the expected). By elimination I can say there's something wrong with the url parameter, but what is it?

OBS: I'm using rawurlencode() to encode the URL.

EDIT: Code you asked...

In the first view, where the link is (http://www.linkebuy.com.br/notebook/detalhe?id=5):

<!-- url() function just completes the right URL (production or development) -->
<a href="<?php echo url('linkebuy/parceiro/?url=' . rawurlencode($l->getUrl()), true) ?>" class="<?php echo $leadClass ?> oferta" target="_blank">
    <?php echo $l->getNomeFantasia() ?>
</a>

When clicked the link redirects to an action (/linkebuy/parceiro), where happens the following (basicly nothing, just keeping in the framework):

public function execute($request, $response) {
    $response->addParameter('url', rawurldecode($request->getParameter('url', ''))); //This creates $url in the view
    $response->setTemplate('site/linkebuy/lead-parceiro.php'); //Forwards to the view
}

It includes the view, lead-parceiro.php (above on the question, I link to this page), where the head contains:

<script type="text/javascript">
    setInterval(function(){ window.location = '<?php echo $url ?>'; },3000);
</script>

Use simple urlencode() and tell us if that makes any difference. — Tomasz Kowalczyk

The problem is in your redirect function....show us the code ;) — Hackerman

I think is probably an apache config restriction not allowing to have http:// on your querystring — Ateszki

If you can't get rid of the restriction you can pass the url in 2 parts like this

http://www.linkebuy.com.br/linkebuy/parceiro?protocol=http&url=www.google.com

And then parse it on your code to make the full url for the redirect.

YEAH! You're right! How can I get this fixed? I mean, fix the apache config.

I'm not sure, this is probably a rewrite rule cheking your querystring. Look at the .htaccess files and the apache conf files to find it.

Have a look at this answer, as your site is at hostgator, the accepted answer must be relevant stackoverflow.com/questions/10992219/…

For those who are searching for an alternative answer, you can base64_encode the URL and base64_decode it later.

You should use urlencode when you pass anything as URL parameter
