Session variables between functions

[Anon]

I have an include file.

In this include file there is a function that attempts to create a session variable.

The code this function uses to create a session variable is:
$TestData = 69;
if(session_register('TestData'))
echo "<p>Done</p>";
else
echo "<p>Error</p>";
$TestData = 69;

Then there is another function within the include file:

function checkObject()
{
session_register('TestData');
echo "<p>Test data out: " . $TestData . "</p>";
}

The include file is included in another php file. at the head of this php file there is a session_start() when I call the function to create the session variable from this page it prints out "Done". Then I call checkObject and the testdata is not printed out.

Am I doing this correctly how do you set a session variable and access from any point of code???

I know this kind of question has been asked before and I read in the archives but there wasnt a kind of fool proof explanation...

Thanks

you can register the variable with a "error code" value (like -1) and then set it to the value based on your criteria later. That makes the checking that you are doing a little easier, no?

But how?

Can anyone give any demo code of how to just setup a variable in a session object in one function.

and from another function read that value out again

I have been able to get nothing to work in terms of storing variables in the session.

(I have a php version > 4)

Thanks

if you do:
//----begining of you code:
session_start();
$myVar = "thisValue";
session_register("myVar");

/then my var is accessible from every pages that will begin its code with session_start()./

if you call your function and declare inside globale $myVar; then should be ok all is OK.

It that was it;-)
