passing data accross multiple pages

[nate2099]

Hi, Im currently building a directory type site. I have a registration procedure covering about 3 pages. What is the best way to pass data to the final page to be written to the database?

ideas currently are:

A cookie, although peolple may not trust cookies from an unknown site,

Write to the database at the start of each page, problems may occur if multiple people are registering at the same time,

or to create a temp file on the server for each new registration, no idea how to do this as yet..

Or I can pass the data through the pages in hidden text inputs..

I'm a bit out of my depth on this, but am doing it both as a commercial site, and to learn more about database driven websites.. any help, ideas or info on potential traps appreciated!

Nate.

If you're using PHP then using a session is your best bet.

It's quite easy to use a session: At the top of each page that needs to access the data call the session_start function and use the following syntax to create and access variables in the session:

first page:

PHP: Select all

session_start();
$_SESSION['bla']=2;
$_SESSION['blub']="hello"; 

second page:

PHP: Select all

session_start();
$bla_value=$_SESSION['bla'];
$blub_value=$_SESSION['blub']; 

Now, if you write 'echo($bla_value); echo(" - "); echo($blub_value);' you would get the following output: "2 - hello".

Hope that works and hope you can understand that...
Check out this page on php.net for more info on using sessions.
