simple post redirect get code example


simple post redirect get code example  using -'php'

I have found many sites that describes PRG, but no simple PHP code example.



Here's what I implemented:


The form.php has an action: validate.php.
The validate.php is never seen by the user; if validates all $_GET and, if valid writes it to database and generates the HTML of a confirmation page / if not valid, it generates the HTML of an error page explaining what is wrong.
Whichever HTML is generated get stored in a $_SESSION variable and then validate.php calls header('Location: <as appropriate>);.
The submitted.php of invalid_input.php (in case the user reads the URL) consists only of echo $_SESSION['form_html'];.


That seems to me like protection against both page reload and back button problems.

Did I goof by trying to reinvent the wheel?
