Getting url string of clicked link in php sript

[glavca]

Hi,

 

I have url's on my page like this '<a href="activate.php?url=http://www.site.com/something-dynamic-changing-link'>Linkname</a>

 

When user clicks on link, the script activate.php is executing. The problem is that I can't get the url string http://www.site.com/something-dynamic-changing-link in a variable $link in the activate.php script. The url's are dynamic, but they all begin with "activate.php?url="

 

How can I put the url string into variable $link, that is used in activate.php script?

 

Is this possible?

 

Please help.

You should be able to retrieve the url string, since it's being passed as part of a url query, using $_GET(). Something like...

 

if ( isset($_GET['url']) ) {
    $link = $_GET['url'];
} else {
// Default url <OR> Error message.
};

 

Note that you should also perform some kind of validation of the url string to make sure it is something that it's supposed to be, to protect against XSS attacks and the like. A quick google should help, or see http://php.robm.me.uk/

When you build the URLs, you should run the external URLs through urlencode(), and then urldecode() in activate.php.

Thanks for your code, but there is a little problem. I try your code, but didn't get the whole link.

 

link on my page: http://www.mypage.com/calculator.php?id=1196642&arb_uid=|AH%202,1|EH%20X,-1|EH%201,-1|&arb_type=TARB00X2&stakes[]=100&odds[]=1.3&odds[]=4.333&odds[]=7

 

the result in variable $link in activate.php http://www.mypage.com/calculator.php?id=1196642

 

I'm missing a part of a link.

Look at what thebadbad has suggested.

<?php
if(isset($_GET['url'])) {
$link = urldecode($_GET['url']);
echo $link;
}
?>
<a href="?url=<?php echo urlencode("http://www.site.com/something-dynamic-changing-link") ?>" />Linkname</a>
