[Resolved] hidden value not working locally

bike5

I am creating a form locally and to detect of someone has submitted the form I used a hidden field. When I do this locally my page acts like the variable is not set. I even went as much as doing <form name="join" method="post" action="join.php?sent=true "> and it still did not read "sent" as anything. But, when I upload and test of my web server the hidden feild works fine. Why is my local host not reading it? Any ideas on what I can do? Thanks a lot in advance.

Don't put form variables in the form submit URL. Use a hidden field instead:

[Edit]
On re-read it sounds like you tried that...
Could the difference be register_globals? Are you looking for $sent or $_POST['sent'] ? If you're doing the former, try the latter. More info here:
[man]register_globals[/man]

I was using the "$sent". The $_POST worked. Thanks a lot.

Also, the form submits to it self(same page) so should I use "if(isset($POST['sent'])=..." or just "if($POST['sent'])=..." because I don't want any warning says there is no $post because the form hassn;t been submitted yet when they first load the page.

Thanks again.

You will get no warnings by default, but if you set error_reporting(E_ALL) you will get warnings unless you check isset first. It's best to use error_reporting(E_ALL) though, because if you do something like this:

$thing = "foo";
echo $thign;

you'll get a warning about the typo on "$thign". With the default error reporting typos like that would quietly continue and leave you scratching your head wondering where your data went.

To use error_reporting(E_ALL) yet avoid the constant isset checks on form variables, try something like this:

function getvar($varname, $default = '') {
    if (isset($_REQUEST[$varname])) {
        return $_REQUEST[$varname];
    }
    else {
        return $default;
    }
}

Then you can just do
if (getvar('sent') != '') ...
without having to mess with isset.
