Re: [PHP] UNSETing Session Variables
I tried to enter the comand as such
unset ($_SESSION[choice]);
I thought everything in php was double quotes. but even with single quotes
it still isn't quite working. If I do it on the first page then it won't
let a later command assign anything to the variable, but if I do it on a
seperate third page, it doesn't reset anything.
I have been trying to avoid unregistering variables and then reseting
them. Seems a little too messy for my programming tastes.

Re: [PHP] UNSETing Session Variables
I more or less figured that. below is the code for the two pages in
question.
Page 1:
?
require(connect.inc);
unset ($_SESSION['currentbid']);
?
HEAD
TITLE/TITLE
/HEAD
BODY
Borrowers
TABLE BORDER=1
TR
?
/* Get all users select call */
$users = mysql_query(SELECT bname, bphone, address, admin, bid FROM
Borrowers ORDER BY bname);
echo TH; echo Name; echo /TH;
echo TH; echo Phone; echo /TH;
echo TH; echo Address; echo /TH;
echo TH; echo Admin; echo /TH;
echo TR;
if($users)
while($row=mysql_fetch_row($users))
{
echo TR;
echo TD $row[0] /TD;
echo TD $row[1] /TD;
echo TD $row[2] /TD;
if($row[3])
echo TD Yes /TD;
else
echo TD No /TD;
print TD FORM METHOD=\post\ action=\uupdate.php\
input type=\hidden\ name=\ubid\ value=\$row[4]\
INPUT TYPE=\SUBMIT\ VALUE=\Change User.\

/FORM /TD;
echo /TR\n;
}
?
/TR
/TABLE
? require(tail.inc) ?
page2:
?
require(connect.inc);
?

?
print $currentbid-current, $ubid-change, $bid-current;
?
?
if($admin)
$currentbid = $ubid;
else
$currentbid = $bid;
$result = mysql_query(SELECT bname, bphone, address FROM Borrowers
Where bid=$currentbid);
if($result)
{
$row = mysql_fetch_row($result);
$oname = $row[0];
$ophone = $row[1];
$oaddress = $row[2];
}
?
Please enter the new information into the fields below.
TABLE BORDER
TRTH Current Information /TH/TR
TRTHFORM method=post action=ucupdate.php
INPUT TYPE=text NAME=uname value=?print '$oname'?
SIZE=30/TH

if($admin)
{
print THINPUT TYPE=\text\ NAME=\upassword\ value=;
$cpass = mysql_query(SELECT admin_pass FROM Borrowers WHERE
bid=$currentbid);
$cpassr = mysql_fetch_row($cpass);
print \$cpassr[0]\ ;
print SIZE=\30\/TH/TR;
}
?
/TABLE
INPUT TYPE=SUBMIT VALUE=Submit your information.
INPUT TYPE=RESET VALUE=Clear
/FORM
? require(tail.inc); ?
The first page gives the admin user a list of users, and three options
(change their information, delete them, or make them and Admin). The
option we are choosing is to change information. If I select user number
1 the only way to edit another user is to log out and log back in.
If any of the code is unclear please let me know. I haven't gotten to
commenting it all yet.

$_SESSION['currentbid'] isn't available until you do session_start();
session_start();
unset($_SESSION['currentbid']);
Or is this what does connect.inc contains?

Re: [PHP] UNSETing Session Variables
I fear you're missing something fundemental here. The active session needs to be
requested for each script. So session_start() needs to be called at the top of each
script (or at least before any output). Example..
page 1
--
?
session_start();
$myvar = foo bar;
session_register('myvar');
// or //
$_SESSION['myvar'] = $myvar;
?
page 2
-
?
session_start();
unset($_SESSION['myvar'];
// or //
session_unregister('myvar');
?

Re: [PHP] UNSETing Session Variables
You only have to register the session variables once. If you need to register the
same variables again (such as for a different user), then you should use
session_destroy() before registering the variables again.
The variables should be available throughout your pages as long as session_start() is
done before ANY output goes to the HTML. It's usually best to have it as the FIRST
thing on your pages.

/me feels kinda dumb now.
Well even after adding session_start to my connect.inc, it doesn't work. I
only need to do session_register() once correct? Or do I need to do that
everytime I do session start? If I have to do it everytime then what is
the point of sessions?
