[RESOLVED] form data lost in the redirect page

pn00b

Hi guys,

How to retain the form data via redirect page? on the example below when i submit, no form data is passed to either add.php or subtract.php.

How do i solve this problem?

index.html

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="redirect.php" method = "post">
 Number 1: <input type="text" name = "number1"><br>
 Number 2: <input type="text" name="number2"><br>
<input type="submit" name = "sel" value="add">
<input type="submit" name="sel" value="subtract">
</form>
</body>
</html>

redirect.php

<?php
	switch ($_POST['sel']){
		//if we add
		case 'add':
			header("Location: add.php");
			break;
		//if we subtract	
		case 'subtract':
			header("Location: subtract.php");
			break;
	}
	//exit;
?>

add.php

<?php

echo $_POST['number1']
." + ". $_POST['number2']." = "
. ($_POST['number1']+$_POST['number2']);

?>

subtract.php

<?php

echo $_POST['number1']
." + ". $_POST['number2']." = "
. ($_POST['number1']-$_POST['number2']);

?>

while you could put the form data in a session, i would just drop the switch and redirect, and process the form on the page it is submitted to.

hi,
how can i use the session to retain my data?

dagon

the simplest approach

$_SESSION['form_post']=$_POST;

i added these on my redirect.php

session_start();
$_SESSION['number1'] = $_POST['number1];
$_SESSION['number2'] = $_POST['number2'];

but still can't get the values of sessions in my add and subtract pages.

dagon

on add\subtract page add

session_start();
print_r($_SESSION);

oh. its working now. thanks

I was using

[COLOR="Red"]$_session[/COLOR]

instead of

 [COLOR="Red"]$_SESSION[/COLOR]

in add/subtract page.
