Re: [PHP] Problem about Reading input from a Form

[Stewart G.]

Its not a register_globals issue. You must wrap $user and $address in php 
print statements rather than just in the html.

Your name is .
Your address is .

That will work with either GET or POST.

Re: [PHP] Re: form submission error trapping

[Stewart G.]

You do not need to use javascript.

Simple create a form that submits to itself. And check the values, then 
reprint the form or redirect.

Example:
\n";
}
  }

  if (!empty($err_msg)) print $err_msg;
}
?>







Hope that helps,
