将表单提交到php页面，并保留POST数据以重定向页面

Question

I have found some general info on this question but nothing seems to answer my exact question.

I have a form on a .php page, that when submitted POST's the inputs to another php page, which sends the form inputs to my email and then redirects to another php page using (Location: page.php)

so: form.php --> email.php (hidden) --redirect--> submitted.php

I would like to have an input from form.php be carried over to a hidden input box on submitted.php

I hope this makes sense, thanks in advance for your help!

edit:

on submitted.php I will have a single hidden form input. I need the value of that input to be equal to one of the inputs from form.php. I will then POST that input to another php page (not seen above) that will send it to my email.

Answer 1

Simply, put your sending email code in your submitted.php code and using sessions prevent user from duplicating his input by pressing F5 or refreshing submitted.php as follows:

in form.php

session_start();
$_SESSION['submit'] = true;

in submited.php

session_start();
if (isset($_SESSION['submit']) && $_SESSION['submit']){

/*
* do your code
*/
  $_SESSION['submit'] = false;
}
else{
  echo 'some error';
}
