Geoff,
The parameters you send with a request are name/value pairs. The
'parameters' option to Ajax.request can accept either a url-encoded
string, or any Hash-compatible object from which it can get the names
and values to send (see http://www.prototypejs.org/api/ajax/options).
>From the code you posted, unless 'counter' is a url-encoded string of
some kind, you're not giving any name to your counter value.
Perhaps this:
function send(){
var params = $H({ count: counter });
new Ajax.Updater(
'updateDiv',
'send.php',
{
asynchronous:true,
method:'get',
parameters: params
}
);
}
With this PHP:
<?php
echo "Hello <p>";
$cue = $_GET['count'];
echo $cue;
?>
In the send() method, I'm creating an object with one property (count)
set to the value of the counter variable, and then wrapping that in a
hash via $H (I'm not sure you really need to do that; you might try it
without the $H call and see if it works). (I could have done all that
within the call to Ajax.Updater, but I thought it would be clearer
doing it separately.) Then in the PHP, I'm retrieving the 'count'
parameter.
Hope this helps,
