Save Form Data

[NZ_Kiwis]

I've got a page where i have someone enter some data, such as car type

When i submit this form it goes from entercar.php to carprocess.php on car proccess it enters the data into a database and returns the user to index.php but if there are fields missing it goes back to entercar.php via

header("Location: entercar.php");

when i'm back on this page i want to display all entered data, i thought okay do this

echo isset($_POST['CarType']);

But it does not work, what can i do?

http is stateless, it does not store the headers from a previous request, so you will have to use something like sessions.

Or instead of telling the user's browser to send a GET request for entercar.php (which really should be 'Location: http://example.com/entercar.php' since the location header should always take a parameter with protocol and absolute URI iirc), you could instead use

require ('/path/to/entercar.php');

You will also need to change echo isset(...) into

echo isset($_POST['var']) ? $_POST['var'] : '';
