This method works well in FF 3.5, but FF 3.0.12 doesn't like it... I
really would like to keep the from coming in a separate variable, but
realize I may have to change that.
3.0.12's POST (truncated) just for info:
%7Bstartdate%3A%202009-04-23%2C%20
3.5's POST (truncated):
%7B%22startdate%22%3A%20%222009-04-23%22%2C%
As you can see 3.5 has extra characters...
I'm sending this to PHP, and my processing script receives the JSON
variable as such
$json_string = (isset($_POST['json']) ? rawurldecode($_POST['json']) :
"");
$json = json_decode($json_string, true);
if (($json == '') || empty($json) || ($json == null)) {
$result['valid_result'] = 2;
$result['reason'] = rawurlencode("Unknown error, Administrator has
been notified. Please try again later");
$result = json_encode($result);
header("Content-Type: application/json");
print $result;
exit(0);
}
so when users are using 3.0.xx they always receive this error message,
because the PHP script doesn't see it as valid JSON.
but 3.5 users (myself only) can perform the saves/deletes, etc
This is for an internal application, we only allow FF to be used.
Thanks for the help!
