registering session variables from within a function

F_AssMonkey

.< doh im a n00b

i've made a function that pulls a loads of variables out of a database and then tries to register them with the session.

but it don't work 🙁 by the end of the script when php comes to register all the variables they're not set anymore because it's outside of the function

I know this is n00b3h problem... but dammit i cant fix it :mad: lol

any suggestions r greatly apprieciated 🙂

and while im here... you can probably pick all sorts of holes in my code... im learning and my code isn't particularly effiecient yet

this is the function...

function logemin($db_memtable,$auth,$nickname){
if($auth=="yes" || $auth=="isadmin" || $auth=="chatowner"){
$querystr=("SELECT * FROM $db_memtable WHERE nickname='$nickname'");
$result=dbretrieve($querystr);
while ($row = mysql_fetch_array($result)) {
$ID=$row[ID];

		if($row[admin]==5) { $admin=5; }
		elseif($auth=="chatowner" || $row[admin]==4) { $admin=4; }
		elseif($auth=="isadmin" || $row[admin]==3) { $admin=3; }
		elseif($auth=="yes") { $admin=2; }
		else { $admin=$row[admin]; }

		$lastlogin=$row[lastlogin];
		$email=$row[email];
		$homepage=$row[homepage];
		$preferences=$row[preferences];
		if($preferences=="set")			{
			$M_fontcol1=$row[M_fontcol1];
			$M_fontcol2=$row[M_fontcol2];
			$M_fontcol3=$row[M_fontcol3];
			$M_hlcol=$row[M_hlcol];
			$M_linkcol=$row[M_linkcol];
			$M_vlinkcol=$row[M_vlinkcol];
			$M_alinkcol=$row[M_alinkcol];
			$M_fonts=$row[M_fonts];
			$M_textsize=$row[M_textsize];

		}
	}

	$auth="logged";
	session_register("auth","ID","nickname","admin","lastlogin","email","homepage","preferences","M_fontcol1","M_fontcol2","M_fontcol3","M_hlcol","M_linkcol","M_vlinkcol","M_alinkcol","M_fonts","M_textsize");
	return($auth);

}
elseif($auth=="passlock")	{
	$ID="Guest";
	$admin=1;
	$preferences="unset";
	$auth="logged";
	session_register("auth","ID","nickname","admin","preferences");
	return($auth);
}

}

Short answer would be to point you to the section in the manual on variable scope (particularly the global keyword).

Better answer would be to recommend forgetting about using session_register() to register variables anyway.

Instead, just use session_start() as usual, and all your session variables will already be available for reading and altering in the $_SESSION[] array with no further effort required.

session_start();
echo $SESSION['varname'];
$SESSION['another_var']="Something to be sessioned";

would i have to call session_start() from inside the function to do that?
I tried using $_SESSION[] in my attempts to get it working but to no avail

i also tried putting all the variables into an array and returning the array, but unfortunately i cant work out how to turn the array back into varables at the other end without specifing exactly which variables i want i.e $lastlogin=$var_array['lastlogin'];
i want something like variablename=$var_array[key] & variablevalue=$var_array[value]
if you can solve that little conundrum for me i'd be most grateful

but thanks alot anyway... i'll work it out in the end 🙂

Well, I did say that you'd still be using session_start().

If $_SESSION[] is not working, and you do have session_start() before you start using the array (session_start() fills out the array), then perhaps you're using a version of PHP older than 4.1? If that's the case then you'd be needing to use $HTTP_SESSION_VARS[], and you'll need to declare it global in the functions that use it. Much nicer in the long run to go with a newer version of PHP.
