really simple php function... I think

« on: November 16, 2011, 10:42:37 AM »

folks I want to knock up a page that users can visit to find out the status of something. It only really needs to return "yes" or "no". Users also need to be able to toggle the status by clicking a link so that other users can see it. I imagin the page markup would look like this:

Code:

<body>
<h1>No</h1>

<a href="?status=yes">set status to yes</a>
</body>

I guess the easiest way to do this would be to have a txt file on the server which php can update when a user clicks a link. The trouble is I have no idea how to do this. Any pointers would be greatly appreciated.

Code:

<?php
if (isset($_GET['status']) && ($_GET['status'] == 'yes' || $_GET['status'] == 'no')) {
    file_put_contents('./status', $_GET['status']);
    $status = $_GET['status'];
} else {
    $status = file_get_contents('./status');
}
if ($status == 'yes') {
?>
<h1>Yes</h1>
<a href="?status=no">set status to no</a>
<?php } else { ?>
<h1>No</h1>
<a href="?status=yes">set status to yes</a>
<?php } ?>

You'll have to create the ./status file (and maybe call it something else) and make it writable.
