form processing within a function?

[Anon]

I am trying to process a form, but the way it is setup requires that the form be displayed in a function, and that the same function processes itself.

However I can't see any of the POST variables (within the function) after submission, even when I register $_POST as a global. Is there anyway i can embed the form via a function call, and have it submit to itself, and have it process itself/throw user errors all in the same function?

why not set the form up as one funtion and have the processes of the form as another...

You could then call the processing function with a hidden form field..

Because I want to try and avoid doing stuff like if ($_POST['process']) { return formProc(); }. The function is already there and doing it's stuff, so why should I tell it to do more stuff? I suppose you could say I am trying to get it self-aware...

But why when I register $POST as a global can I not access any of the $POST items within the function that has the POST registered??

This is a massive site, I'm making it as encapsulated as I can. And I am trying to avoid doing this like declaring each variable name as a global (and it does work that way) in order to get into the scope, but then you can spoof those kinds of variables...

Let me see if I understand you. You have a function that generates a form. You submit the form. You want the same function that generated the form to proccess it.

<?
function form () {
extract ($GLOBALS);
extract ($_POST);
if (!isset ($submit)) {
echo '
<form action="' . $PHP_SELF . '" method="post">
name: <input type="text" name="name"><br>
<input type="submit" name="submit">
</form>
';
}
if (isset ($submit)) {
echo 'Dear ' . $name . ', thank you for filling out my form.';
}
}

form ();
?>

$_POST['variable'] is already global and should not be specified using global in your function. Maybe that helps?
