Replacing old query strings

[castus]

Hi,

I have a form which posts back onto the current url including the query strings, using the get method. I used the get method due to my pagination being outside of the form, therefore I needed to always have the form results in the url. Now when I post back to this url if a query string like ?page=1 is present nad I want page2, then the url querystring becomes ?page=1&page=2.

This works just fine as the last query is taken, but if you search for a little while the query strings can make the url infinitely long - and it just looks a mess.

There must be a solution to this - just one that I'm not aware of 🙁

Thanks,

Gary

function removeQueryKey($key, $querystring){
parse_str($querystring,$a);
unset($a[$key]);
return http_build_query($a);
}

That can be called like so:

echo removeQueryKey('page', 'page=1&login=true&value=cheese');

And will return "login=true&value=cheese" which you can use in the url for the form thing...

I can't seem to get this to work. Do I have to do anything else with the values to get the syntax right?

$url="http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

function removeQueryKey($key, $querystring){
parse_str($querystring,$a);
unset($a[$key]);
return http_build_query($a);
}

echo removeQueryKey('page', $url);

Lol, I don't know, I was just messing with query strings, what do your pagination links look like?

unset($_GET['page']);
$url = $_SERVER['PHP_SELF'] . '?' . http_build_query($_GET);
?>
<a href="<?php echo $url; ?>&page=3">Page 3</a><a href="<?php echo $url; ?>&page=4">Page 4</a>
