I think I really don't understand what do you want... hehehe :)
which is fine!
but take that code I sent ya... now I'll explain the functions... then tell
me if I'm right:
function ShowHeader
{
?>
<html>
<title>Something</title>
<body>
<?
}
function ShowFooter()
{
?>
</body>
</html>
<?
}
function ShowForm()
{
global $SCRIPT_NAME:
?>
<form ... bla bla bla action="<?=$SCRIPT_NAME?>">
<input type=hidden name=action value="process-form">
<?
}
function ProcessForm()
{
if( !ValidateFormFields() )
return false;
else
{
if( !ExecuteDBInsert() )
return false;
else
return true;
}
}
wouldn't that work?
there's no $done variable here... the return of the function is all you
need... if it's true redirect, if not display error...
