[PHP-DB] Session
Hi, I have a problem with my session variables. I set them using for e.g., $_SESSION[user]=$name; However, because of weak network links, somehow my $_SESSION variables get unset. Is there a way to still keep the session variables even though the network is unstable?? i.e. as long as my browser is open, is there a way to still store my session variables? by the way, i'm not referring to the session ids, I'm referring to the variables that i wanted to session_register(). Thank you. Regards, Hwee
Re: [PHP-DB] login script
Here you go:
Table:
ID Login PW Admin
1 admin abc123 1
2 normal bcd234 0
3 normal2 cde345 0
PHP:
[BOF]
?php
if($_POST['login']) {
$result = mysql_query(select * from users where login = ' .
$_POST['login'] . ') or die(mysql_error());
if (mysql_num_rows($result)) {
$data = mysql_fetch_array($result);
if ($data[2] == $_POST['pw']) {
$_SESSION['login'] = $data[1];
if ($data[3]) {
$_SESSION['admin'] = true;
}
header(Location: logged_in.php);
exit;
} else {
$error = Wrong password;
}
} else {
$error = No such user!;
}
}
if ($error) {
echo span class=\loginError\$error/spanbr /;
}
?
html
head
titleLogin Script by [EMAIL PROTECTED]/title
style
!--
.error {
color: #ff;
}
--
/style
head
body bgcolor=#FF
form action=login.php method=post
Login name: input type=text name=login value=?php echo
$_POST['login'] ? /br /
Password: input type=password name=pw /br /
input type=submit value=Login /br /
/form
/body
/html
[EOF]
In your admin system, just check for the variable $_SESSION['admin'].
If true, the user is admin and can do cool stuff.. ;)
I don't care about just having given you a lot of script, since I write
at least 3 of these per week.
And, make sure there is nothing echoed either by PHP or HTML before the
login script (or else the redirecting upon successful login won't work)

Re: [PHP-DB] login script
Err...
As usual I forgot the most important part...
Add
session_start()
just above the
if($_POST['login']) {
row, or it won't work at all.. ;)
Or rather, it'll work, but no sessions will be saved.

Re: [PHP-DB] Session
Session objects has nothing to do with weak network connections. If your sessions gets un-set, it's most probably because you forgot the session_start(); command in the beginning of some file that is using sessions. Without that line, no sessions will be neither stored nor read. Mike On Apr 27, 2004, at 07:46, Ng Hwee Hwee wrote: Hi, I have a problem with my session variables.

Take alook at this option:
ini_set('session.gc_maxlifetime', 3600); // 3600 seconds
If you don't set it the standard value is 1440 seconds, then your session
data is deleted based on the garbage probablility. Take a look here:
http://de3.php.net/session
Look out for session.gc_maxlifetime and session.gc_probability.

Re: [PHP-DB] Session
Hi Torsten,
That is a wonderful insight!!! :o) thanxxx!
okie, my 'session.gc_maxlifetime' = 1440 and session.gc_probability = 1.
so, should I change it to something like 43,200 (12hours*60mins*60sec)?? for example,
one person works a maximun of 12 hours a day. But does it mean that by lengthening
this value, the session will still be kept even if the user closes his browser??
Please advice!
looking forward to solving this!!
many thanks,

Re: [PHP-DB] Session
Hi Hwee,
of course you could set it to 43200 seonds if you want. The
session.gc_probability value should stay 1 which means that the session data
is deleted with a probability of 1 percent.
The session life time itself is not critical - the life time of the session
DATA is. Which means you should unset all session data after the desired
period of time. Maybe it's easier for you to use a ready-made package like
PEAR::Auth or PEAR::LiveUser:
http://pear.php.net/package/Auth
http://pear.php.net/package/LiveUser
Hope this helps,

just would like to clarify what do you mean by

DATA is. Which means you should unset all session data after the desired
period of time.
does it mean that if I set 'session.gc_maxlifetime' = 43200 and then make
sure my user logoff, where my logoff script unset all the sessions, then I'm
on a safe track? I'm designing an intranet, so I can instruct my staff to
logoff and not just close the browser. Will this be okay? I'm not familar
with PEAR yet, but surely would like to learn more about it in future!!
look forward to your reply!

If you unset all session data you should be safe, but it's better to REALLY
destroy all session data with session_destroy() - take a look at the manual:
http://de.php.net/session_destroy
This should be called when your users logout. The is the preferred way to
end the session. Your users should not just close the browser window - the
session will still be active then and all session data would still be
available if someone gets hold of the session id. After the logout you
should redirect to the login screen WITHOUT forwarding the session id so
that a new session is started.
I'm not familiar with PEAR::Auth nor PEAR::LiveUser - take a look at it and
decide if it's what you want. I'm using the PEAR::HTTP_Session package to
control the session data and have my own Auth class to check if a user is
logged in, the session is expired and so on.

But does it mean that by lengthening this value, the session will still be kept even if the user closes his browser?? Setting your gc_maxlifetime to that means that the server will not delete the users session data files until they are over 43200 seconds old, meaning the user hasn't requested a page in over 12 hours.

Re: [PHP-DB] Session
Hi - John W. Holmes wrote: The session does not exist past the point of closing the browser unless you increase the lifetime of the session cookie itself. I would recommend you just leave it at zero, though, meaning it only persists for as long as the browser window is open. The longer you make the sessions last, the easier it is for someone to hijack them. One point of clarification here. The *cookie* doesn't exist past the point of closing the browser, but the session file (assuming using files) will continue to exist until it has been garbage collected or until session_destroy() is called. Also, if you weren't using cookies (were passing session id in URL) you could open your browser again and navigate back using your history you'd still be logged in. That's why it's a good idea to always call session_destroy() when a user logs out. That will effectively delete all session data on the server. Of course, as John mentions, once the user closes the browser the in-memory cookie will be deleted and (if you're using only cookies) there's no longer any connection between that client computer and the session stored on the server. In that respect the session exists no longer, but as mentioned the data will still be there on the server. If someone knows (e.g. hijacker) the session ID, they can revive the session by just adding it to the URL. On that note, here are a few things you might want to consider if you want to make sessions more secure: - use only cookies for sessions. (session.use_only_cookies = 1) This prevents the session ID from *ever* being added to the URL. URLs get logged -- by apache, by proxy servers, by user bookmarks :) -- and if a URL contains a session ID then you have that mentioned problem where a session can be easily revived after the user closes the browser (effectively session hijacking, intentional or not). - regenerate the session id when a user logs in. simply run session_regenerate_id() after the username/password has been verified. This goes a long way to prevent session fixation, another type of session attack in which an attacker makes a user log in using a fixed session id (e.g. by clicking on a link that includes something like PHPSESSID=1234); once the user logs in using this fake session id, the attacker can use that session id in order to have access to the system as whichever user logged in. (Do a search on session fixation for more information on that.) - keep your gc_maxlifetime as small as possible; that way if a user does close their browser their session won't remain active for 12+ hours. You might want to consider ways of periodically refreshing the page using an iframe or even just a meta refresh... solution. That will address the need to stay logged-in while the browser is open, while also allowing you to have a very brief session lifetime.

Re: [PHP-DB] Session
From: Hans Lellelid [EMAIL PROTECTED] - keep your gc_maxlifetime as small as possible; that way if a user does close their browser their session won't remain active for 12+ hours. You might want to consider ways of periodically refreshing the page using an iframe or even just a meta refresh... solution. That will address the need to stay logged-in while the browser is open, while also allowing you to have a very brief session lifetime. Excellent points, Hans. One other thing to add. When a user requests a page and you determine that their session is not valid (probably because they've been inactive too long and the garbage collection deleted their session file), start a new session and store the filename and query string of the request before you redirect back to the login page. Then, after you validate any login, check for the existance of a saved page and query string and redirect there instead of your page page. The end result is a lot cleaner for the user. Sure, they'll have to log in again, but they'll be redirected right back to the page they requested, anyhow. You end up with shorter session files making hijacking harder and less frustration from the user having to navigate back to wherever they were. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This might be the way to go for an intranet application, like Hwee is going to do, but not for a website with a wide audience because you are reliant on the user's client (browser) accepting cookies. One could log the user's user agent ident string or his ip address and check those with every page request for further security. Anyway, very good pieces of advice. Thanks, Hans!

Re: [PHP-DB] Request for help on (My)SQL Statement
Well then there's no reason to copy the value. Just select from the BB table.
Just:
$l = mysql_fetch_array(mysql_query(SELECT max(post_time) as latest_post FROM
nuke_phpbb_posts));
$s = mysql_fetch_array(mysql_query(SELECT max(script_run_date) as
latest_script from script_data)
if ($l['latest_post'] $s['latest_script']) {
echo NEW POSTS!;
}
Or something of that nature. I've done this in the past by setting a cookie on
the user's system when they log in so I know the last time they logged in,
and then you can count how many posts have been made since they were there
last.. that works pretty good.

UPDATE ngc_polling SET lastrundate = (SELECT max(post_time) FROM
nuke_phpbb_posts);

Subject: [PHP-DB] Request for help on (My)SQL Statement
:::Novice Alert:::
I've done simple select and insert statements, so I suppose this is the
most complicated thing I've tried to do. but seems to me it should be
pretty easy. But I'm a designer by background, not a developer or
programmer. I've got everything else I'm trying to do working.
I'm trying to take the largest value out of one table and update
another table. The former is a PHPBB table and the latter is a table I
created just to store the value of the date of the most recent post for
use in something else.
UPDATE ngc_polling SET lastrundate = max(nuke_phpbb_posts.post_time)
It returns Invalid use of group function.
I've been looking at the documentation on MySQL.com to no avail. I'm
testing my query in phpMyAdmin before I try to implement it elsewhere.
This is what I'm trying to do, any help besides RTFM (been doing
that) would be greatly appreciated.
Thanks!
John

What PHP function returns just the first letter of a string?
echo substr($str,0,1);
or
echo $str{0};

Re: [PHP-DB] Session
Depends on the browser. IE and Netscsape handle opening another window differently. Hi, I have a problem in handling session... so I just reply in this topic.

Re: [PHP-DB] Session
Do you mean a new browser window or a new browser? Like using IE first and then netscape? If it's the latter, it wont be saved. It generates a new session ID and wont use the same session as the first browser. -- Marcjon -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] MySQL - counting number of instances of a word in a field
Hi guys, I'm trying to find a MySQL function(s) that will allow me to count the number of words in a field. For eg: [table: pages] id - title - keywords - body 1 - Home - home, page - This is my home page. p Enjoy your stay. 2 - Feedback - feedback, form, contact - Please enter any feedback or comments in the form below.brYour feedback will be used to improve our service. How do I, for example, count the number of instances of a word such as feedback in say the BODY field? I'm putting together a search engine I'd like to 'rank' the results based on the number of instances of each word found in a few fields. In this example, if they search for the words feedback and improve, the count would result in the row id, word searched and the number of instances of that word: (formatting doesn't matter, it's just to give you an idea) id 2: feedback count = 2 id 2: improve count = 1 I can play with the weightings later, just need to figure out the counting... Thanks guys, Gav
[PHP-DB] Re: Session
Hi, Regarding the recent thread on sessions. If you want cookies to expire after the user leaves the sie or closes the browser do not leave the expiry date emty. 9 times out of 10 the cookie will remain. All you need to do is set a date that has passed. Like 1st Jan 2000. Most set it way back to 1980 because some people reset their dates and what not for Program hijacking etc. So 1980 is a good limit. You can use any date passed and it will expire, any future date it won't expire until the date has been reached/passed. Regarding using $ variables. I have seen on some servers you can easily use $the vairable but some servers don't like the user of $ . I have never seen an explaination to why this occours, so thought I'd mention it. If the session is unset 9 out of 10 times the $ may be a problem on your server and you will need to look at alternative methods. J Find local movie times and trailers on Yahoo!
