Trouble with Sessions

[Anon]

I have been trying to use the new session stuff in php4. The homepage will set the session_id and every link and form in the page automatically has a variable called PHPSESSID set to the current session_id. When the user clicks on the cart code that passes values for several fields including the PHPSESSID to the next page. The next page only contains a link back to the home page with the ?PHPSESSID=$PHPSESSID attached. The session_id passes back just fine and even shows in the code the correct session_id value. The problem is that as soon as the form is submitted again, the session_id changes. The cart page does not have any calls to setting session_id anywhere. I can't figure out why. Any ideas?

Hi
i Think the problem is that knew session ids are getting generated each time you submit the form.Just try my code.

Register this in the home page
<?
session_register("name");
$name=saravanan;?>

in the above code name is my session name
and saravanan is the value assigned to it

Then tp retrive the value of this session use

session_start();
session_name($name);
$myname=session_name();

Note:This code shuld be before ur Html codes
Good Luck
Saravanan

Headers already sent just means you have printed some text before the session_start() was done.
Check your code for stray spaces and newlines.

1) quote your strings when you assign them
$a=saravan; is extremely bad PHP, and only works because PHP has failsafe mechanisms.

2) Session names are not required.

3) Andrew: make sure (and I do mean absolutely sure) that you are passing the session ID along as PHPSESSID.
Preferably you should use session_id() to get the ID, not the var that you are passing along.
PHP will take the session id from the PHPSESSID var, but that doesn not mean you should use it :-)

the better way to avoid that error is to buffer yr output

ob_start() //put before all code and after includes

ob_end_flush() // put as last line on page

this basically buffers all the page output to ram on the server and sends after all processing has been done, as opposed to sending output line by line as is the default.

i'm using wint 4 + apache + mysql+php4.01

Not good because this slows your script down quite a bit. nothing is sent untill the script has completed, making the look at a blank screen.

Clean code rules, workarounds suck.
