将GET变量保持在分页中

Question

I have around 10 GET variables in an HTML form.

These are passes onto search.php, which returns 20 results per page via pagination. However, when I click the "next" page button, it rewrites the url as "?pageno=2". It forgets all the GET variables in the first place.

What's the simplest way I can keep these variables into the next page? I can NOT use Session because I need the user to be open as many instances of the search system as possible, and I cant edit the URL manually because the URL may have 2 variables or 14 variables, depending on what the user selects.

You could use the $_GET array, and http_build_query() function. E.g.

$params = $_GET;
$params['page'] = $page;  // Set previous/next page

$uri = $_SERVER['REQUEST_URI'];
$query = http_build_query($params);

$url = "{$uri}?{$query}";
