php sessions help

[a1amattyj]

hi,

 

very new with sessions here.

 

currently on a "install" code which will install my script. the the pages are all install.php?step=1  ..2..3 etc etc

 

The first page asks for you details then the second grabs them :

 

$database_name = ($_POST['database_name']);

$database_password = ($_POST['database_password']);

$database_user = ($_POST['database_user'])

 

then checks for errors and trys to connect..

 

now, how can i pass this information from install.php?step=1 all the way to step=.. lets say 6

 

i guess session is the best? can someone please advise on how i pass this by a session for the variable $database_name.

 

Thanks

Sessions is the easiest way. You can also dynamically generate hidden form fields to achieve this as well

It would probably be helpful to read the manual on sessions, but as a start...

 

One page 1...

<?php
session_start() // will initiate if it hasn't already and will do nothing if it has
$_SESSION["username"] = $_POST["username"];
?>

 

On page 6...

<?php
session_start()
echo "Welcome to the last page " . $_SESSION["username"];
?>

be sure to have :

session_start()

 

as the very first line of every page, becuase if not, the session will be lost.

And don't forget the ; after them.

 

And it won't be lost, it just won't be available for that page you dont start it on.
