Question

wondering how it is possible to have an anchor which adds a variable to the end of an URL?

So something like /?filter=1 would turn into /?filter=1&p=1

Cheers

EDIT:

If anyone’s interested, I found my own solution in the following format, it’s dynamic and requires no editing! 🙂

//CREATE LINKS BASED ON CURRENT VARIABLES
//REMOVE PARAMETERS WHICH WON'T APPEAR TWICE
    $v = array("p");
    foreach($v as $i) {unset($_GET[$i]);}
    $uri = http_build_query($_GET);
    #if there is a current variable, add & to link
    $uri .= count($_GET)>0 ? "&" : NULL;

and your links would be formatted as such:

echo "<a href='?".$uri."p=$x'>$x</a>";

You can keep adding parameters to the end of your URLS as you suggest:

www.example.com/?one=1&two=2&three=3

These will then be available as $_GET["one"], $_GET["two"] and $_GET["three"] respectively.
