Changing a variable onclick

[pmatos]

Hi all,

How can I in php have a link that reloads the exact same page but
before reloading, changes some variables?

Cheers,

echo '<a href="', $_SERVER['PHP_SELF'],
'?foo=1&bar=2"> Click here to change variables</a>';

When the script reloads, you can access the values of
foo and bar as $_GET['foo'] and $_GET['bar'], respectively.

Or, you could just save them as session variables...

Ah, nice... Didn't know keywords sent in the URL would be sent as GET
variables.

Code to generate a link:

<a href="<?=$_SERV ER['PHP_SELF']?>">Self page</a>


Code to change a variable:

$foo=33;

Of course. That's how the GET method works...

Link to a PHP file that sets the variable, then do a header("HTTP/1.0 204 No
Contents"), so the browser just stays at the current page.
