Session Problems

pilyad

Hi,
I am a newbie for PHP and using PHP-4.0.6 compiled with Apache and MySql.
Trying to code seessions in PHP.

session_start();
.......
if(PASSWORD CORRECT){
global $unumber;
$unumber = $row["unumber"];
session_register("unumber");
}
do_left_menu();
print "Unumber = .$unumber."<br>";

Unumber = XXX line prints correct value but inside do_left_menu() I can not.

do_left_menu()
{
if((session_registered("unumber")){
print "Unumber = $unumber";
}
}

prints NOTHING........though it is EXECUTING the print statement.
If I use $GLOBALS["unumber"] I get the correct value.

Where is the problem? Why can't I refer to the registered variable using $unumber? Why do I have to use GLOBALS array to refer to the registered variable?

PHP is compiled with -enable-track-vars option.

Thanks for all the HELP

Make sure register globals is on.

Although idealy you should probably just use $HTTP_SESSION_VARS['unumber'] or $_SESSION['unumber'] (php 4.1+)

Yes, register_globals = On is in /usr/local/lib/php.ini

And I could use $HTTP_SESSION_VARS or $_SESSION arrays but I am using PHP-4.0.6 I did read that little note on session_start() function page which tell to use 'em in 4.1+
I have tried this before and it used to work with same PHP Version.

What could be wrong?

Thanks for the help

this section:
do_left_menu()
{
if((session_registered("unumber")){
print "Unumber = $unumber";
}
}

you need to add this:
gdo_left_menu()
{
global $HTTP_SESSION_VARS;
if((session_registered("unumber")){
print "Unumber = $unumber";
}
}

although that could not be the only problem (i only glanced over the partial script) .. i have ran into problems before within functions, trying to access session vars..

cheers,

Oh, and here might be some more reading for you to do (since it fits your php version, I believe):

excerpt from: http://www.php.net/manual/en/function.session-register.php

"Caution
This registers a global variable. If you want to register a session variable inside a function, you need to make sure to make it global using global() or use the session arrays as noted below.

"Caution
If you are using $HTTP_SESSION_VARS/$_SESSION, do not use session_register(), session_is_registered() and session_unregister().

"If $SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, assign variable to $SESSION. i.e. $_SESSION['var'] = 'ABC';

so you might want to do global $_SESSION; instead of global $HTTP_SESSION_VARS (depending on what you use).

cheers,
