Question

Im trying to create some links depending on the GET parametre currently set.

My URL looks like this:

http://mysite.com/index.php?bar=test&page=page

In my code I do the following:

$bar = $_REQUEST['bar'];
<a href="index.php?bar=<?php echo $bar?>&page=anotherpage"

But every time I click the link, it adds the whole string to the URL again.

Like first click would give me this URL:

http://mysite.com/index.php?bar=test&page=anotherpagepage=anotherpage

And next click creates:

http://mysite.com/index.php?bar=test&page=anotherpagepage=anotherpagepage=anotherpage

And so on.

Is there any way to only get the request once so that the URL always looks like this:

http://mysite.com/index.php?bar=test&page=anotherpage

No matter how many times I click the link?

Thanks a lot!

You missed an ampersand in your first example. (&). Give this a try:

$bar = $_REQUEST['bar'];
<a href="index.php?bar=<?php echo $bar?>&amp;page=anotherpage"

Or even better, escape your variables before use to prevent XSS, Cross Site Scripting security vulnerability. Use urlencode() for URLs.
http://nl.php.net/manual/en/function.urlencode.php:

$bar = $_REQUEST['bar'];
<a href="index.php?bar=<?=urlencode($bar)?>&amp;page=anotherpage"
