Trouble Passing Variables

loureiro

Hi,

Im having some troubles passing variables through to other frames. I have layed out my page with frames for further security however when i try to pass a variable through I cannot because it sends it through to the frameset page not the actual pages with information. what should i do?

Try registering your variables as session variables and let's see what happens

I have never really been able to do that before. can you help me out? I have always just grabbed my variables using $_POST["name..."]

Rahmon

Use this idea; On your first page register a session variable as array of all submitted (posted) variables in your apps. E.g

at the begining of your logon page for instance you do:

<?
session_start();
session_register("mysession");

// register the submitted username and password
$mysession[username] = $username;
$mysession[password] = $password;

// at this point, both $mysession[username] and $mysession[password] can then be used in your apps as long as the browser in still up.

you could use GET posting to pass on variables from the frameset page to your frame pages

whether you will want to adopt this approach over sessions will depend on the sensitivity on the information being passed

i only write information such as primary keys from tables and information that is used regulary throughout the site

transient information i like to pass to the next page using GET,POST

kind regards

i think im gonna try using session variables. i always wanted to use them tried once didnt get it and then just never tried again

loureiro

so for

mysession[username] = $username;

this will take whatever is in the username field and throw it into the my session variable?

do i put this code right at the very beggining of my login page even though there is no data submitted yet?

loureiro

can anyone please help me out here?

i've created a redirect page where it takes the $_POST values and enters them into the session variables but it doesnt seem to be working

Rahmon suggested an older method of registering session variables; the modern method for assigning a value to a session variable is to use

$_SESSION['sessionvariable'] = $_POST['postedvariable'];

And reading a session variable should be obvious.

Aside from that, the only other thing that's needed is the statement

session_start();

to load up the $_SESSION[] array on each page that uses it.

More details are in the manual's section on [man]session[/man] handling functions.
