Hi =)
Is it possible to track a user session across multiple domains? We have
several related web sites and want to enable a user to login through one
site and end up logged in to them all. I tested and it didn't work and I'm
guessing it's a limitation of cookies. As in, a cookie created under one
domain isn't available to another. Is this right or is there a way to
accomplish what I'm talking about?
Thanks =)

I'm planning to write a simple user login module. I want it to be a
stand-alone class, and not rely on cookies (I'm passing all variables
via GET method anyways, so I just want to pass a session ID in the
URL).
Before I go ahead and do some mistake, could somebody have a look at
the outline of the algorithm I've come up with? Any opinions greately
appreciated.

The algorithm is presented as a flowchart.
p.s. I'd like to "roll my own", even though I know that there is
authentication code available.

maybe faulty memory on my part, but i think I've seen something similar (i.e. "<a name>" is flakey inside tables).
play with putting <a name ..></a> within your <tr> or <h3> tags.

I fricken hate IE. They extend Microsofts lack of case sensitivity where it shouldn't- when I use IE to log into Basilix or other stuff where my login name is michael, it Capitalizes my name and I have to go back and change it. I'm sure there's a way to turn that off somehow- but I'm literally starting to get sick of IE for all its crap assumptions at what it thinks the user really wants to do, and situations where support issues cost companies money because IE capitalized the first letter of the persons login name and the customer wasn't therefore authenticated.
"I didn't capitalize it. Your server capitalized it when I tried to log on. You should fix your server if its case sensitive"
I've hears that more than once.
*sigh*
Sorry for the rant...
Generally, I don't think a login prompt when a user clicks logout is such bad thing.
It lets the user know they are logged out, and the software is waiting for another login.
If they choose to go elsewhere, that's fine.
I personally in your situation would use php to determine the browser. If its IE 5.5 state "Due to a bug in IE 5.5 that browser is not supported for use with this page."
You could give them the choice to continue anyway, or possibly do session authentication only with IE 5.5 if you really wanted to go out of your way to cover up for Microsofts bug.
Don't lessen security because of a browser bug, though- instead, refuse to support the browser.
Just my opinion.

My script does something very similar, but it's more advanced than that, because it handles these various scenarios:
- Someone clicks "logout", then closes browser, then starts new browser and logs in as same of different user - Someone clicks "logout", then tries to log in again as same or different user - Someone just closes browser, without clicking "logout"
This would all work perfectly if it weren't for IE5.5 completely refusing to behave like it has closed when it has closed. So I have to require IE5.5 users to click logout, which is really no good.
Your script suffers the same problem: An IE5.5 user in the 3rd scenario would just get logged right back on without being prompted.

Why it's bad is that, if the user clicks "cancel", they are not logged out. They have to manually clear the field, THEN OK, then they get prompted AGAIN, THEN they hit cancel. That's nuts, and my users aren't going to understand that.

Well, I guess nothing is going to solve my problem of making people hit "logout" instead of just closing the browsers, if they're using IE5.5, since both the user/password are still remembered by the browser, and the session is kept active. I would love to not support IE5.5, but my client uses this version primarily. I will ask them to downgrade...but I wouldn't be surprised if IE doesn't let you install an older version!
Anyway, can someone please test to see if this doesn't happen in IE5.0?
I really hate this situation, yessir.

Why do they need to be able to log out?
If the user doesn't want their password saved (e.g. they're on a public PC) then they just uncheck the "Save password" box when logging in, and then they can close the browser and be "logged out".
If they want their password saved then they can check the "Save password" box and not worry.
It sounds to me like you're trying to implement something that no users are actually going to need or want...
However, if you want more control over the authentication process I suggest making your own login form and using cookies, instead of HTTP authentication. Then you can log users out just by unsetting the cookie(s).

Because they are on a shared computer.

Nope - with IE5.5, even with that box NOT checked, the user remains logged in until either a) the computer is restarted, or b) a new user-authentication header is sent, AND the user clears out the password field and hits OK. Otherwise the user stays logged in, in spite of the HTTP spec.
>It sounds to me like you're trying to implement something that no users are >actually going to need or want...
Nope, I'm working with a real client, who has multiple users on the same machine, and IE5.5 is installed on it, and, lo and behold, though the rest of the browsers work fine, IE5.5 has this awful bug.
>However, if you want more control over the authentication process I suggest >making your own login form and using cookies, instead of HTTP >authentication. Then you can log users out just by unsetting the cookie(s).
This is how I will wind up going, EXCEPT the users will be required to click "logout", since merely closing the browser, in IE5.5, does not seem to clear the user/password from the browser's memory, NOR does it clear any session cookie. Again, works fine in other browsers, per spec.

Ken

Admittedly I'm running IE5.01, but if I close and reopen the browser it will pop up the authentication dialogue again (with values filled out, if I did Save Password).
Does this really not happen in 5.5?

You mean it doesn't clear per-session cookies (expiry=0) either? Cripes...

I don't have this session-terminating problem with IE 5.5 when using Apache and PHP locally on my Win95 computer. I'm also pretty sure it works fine when connected to a Linux/Apache/PHP server where I have some webspace.
Question: Do you have the latest bunch of fixes and security updates for IE 5.5? I remember after I first installed 5.5 a couple of months ago, there were many megabytes of fixes, patches, security updates, etc. (There are probably many more since then.) Perhaps there's already a fix for the bug.
Assuming you have an internet connection from each PC, go into IE 5.5, then select Tools-Windows Update. The MS website should auto-detect the fixes etc that you need and prompt you to install them.

Yes. Someone else on the list wrote, "I didn't believe you until I tried it for myself." At least, it happens in 5.5 on the PC and Mac that my client has. Someone proposed I download any patches MS has, so I'll ask my client to do that, and we'll see if it's fixed. Some members of the list have verified that this happens in IE 5.5, and some members indicate that it is not happening in their IE 5.5. And so far no problem fix has been found on MS's site.

Correct. Expiration is 0. Other browsers on the same system are clearing the cookie when the browser is shut down, including IE 4.

Windows 98 and Mac OS 8 or 9.

I tried to read up on this thread before responding, so please excuse me if I don't know all the facts. Have you tried using PHP's sessions to track user logins? If cookies are available, it takes advantage of them. If not, a session tracking variable is automatically appended to the url.
For my own web site, I register a session variable. For my situation, it happens to be an array, but you may not need this.
if (! IsSet($user) ) { $user = array(); session_register("user"); $user["Username"] = "Guest"; }
From there, present the visitor with a login form. Process the login form and set the $user["Username"] variable after you've confirmed their login. If you want them to log out, they click a link taking them to a page that sets the variable back to $user["Username"] = "Guest". Best of all, if they close their browser, the browser session is lost.
That setup allows people to work at a computer, logout of the web site, and allow someone else to login. Or, they can just close the browser window and let someone else sit down to open a new browser window and login.
There's one thing you'll want to keep in mind, in case you don't already know it. Each browser window you spawn from the original uses the same session. If you login and then press CTRL-N to open additional windows, they will all use the same session. Of course, the way around this is to just run separate copies of the program to gain additional windows.
Another thing of note, in case it will help, I'm using IE5.5 and don't experience the problems you've described.

Is IE set to "Launch browser windows in a separate process" (if that option still exists in 5.5)? Have a look in Tools > Options > Advanced.
Perhaps if that is not checked, closing the window does not count as exiting the browser?

Is this a NT-Domain network ? It's been a few years since i was sysadmining, but the user might have to log off the network domain/workgroup to re-select the credential file (luser.pwl file or whatever Bill & the boys from Redmond call it now). But i'll agree that if IE keeps the authentication after you close the browser, it _is_ borken.

Shu! I am currently working on a site where I want to randomly show pictures. I am using sessions to save the id's of the pictures that a user has seen during his/hers visit. My first question is: Can I use an array as a session variable? like this: $arr = array(1, 2, 3, 4, 5); session_start(); session_register("arr");
This array is to be passed on as an argument to a function used to find a random id, that has not yet been seen. This array should be compared to another array with the picture id's. There is two functions to accomplish the following: Create a randomized array consisting of all the pictures id. Find one id in that randomized array that does not exist in the array of allready seen pictures. These are the functions:
function show_pic($pics_voted, $cat, $sex) { srand ((double) microtime() * 1000000); $result = query("SELECT id FROM $cat WHERE sex='$sex'"); while ($row = mysql_fetch_row($result)) { $arr[] = $row[0]; } shuffle($arr); $picture_id = find_id($pics_voted, $arr); echo "picture_id => $picture_id"; return $picture_id; }//show_pic
//Hitta id som inte finns bland $pics_voted[] function find_id($pics_voted, $random, $x = 0) { for ($i = 0; $i < count($pics_voted); $i++) { if ($random[$x] == $pics_voted[$i] AND $x >= count($random)) return "no_pics"; //If current key in $random[] is equal to current key in $pics_voted[] AND $x is greater than, or equal to the number of keys in $random[], that is if the last key in $random[] has been reached, return "no_pics" elseif ($random[$x] == $pics_voted[$i]) { find_id($pics_voted, $random, $x+1); //If current key in $random[] is equal to current key in $pics_voted[] run the function again, with $x+1 as an argument to be used in the $random[] array, that is: do the funtion again with the next key in $random[] }//elseif }//for return $random[$x];
}//find_id
Does anyone know why this ain't working? I get the same id over and over again. Maybe there is an easuer way to achive what I want? Please help!!

I've protected my PHP pages with this little fragment of script, at the very top of the page
<? session_start(); if( !session_is_registered( "member_id" ) ) { header("Location: user_logon.php\n"); } ?>
When I try indexing the pages, using htdig, all I get is a redirect message. And of course the basic authentication won't work.
Has anyone had any experience of this?
What I am thinking of trying is creating a PHP page to establish a session and then exec'ing htdig from within the page. If that works it will be pretty useful as I'll be able to add it to my Maintenance page. No good, though, for running htdig
Before I try this, though, I'm going to r ead through Coli Viebrock's "Search This!" article.
If anyone has any experience or suggestions for an alternate search engine I'll welcome them.

The following is an example demonstrating how to set up a foreign key constraint in PostgreSQL 7:
CREATE SEQUENCE school_id_seq; CREATE TABLE school ( school_id INT NOT NULL PRIMARY KEY DEFAULT nextval('school_id_seq'), school_name VARCHAR(80) NOT NULL );
CREATE SEQUENCE student_id_seq; CREATE TABLE student ( student_id INT NOT NULL PRIMARY KEY DEFAULT nextval('student_id_seq'), student_name VARCHAR(80) NOT NULL, school_id INT NOT NULL, CONSTRAINT school_exists FOREIGN KEY(school_id) REFERENCES school ON DELETE RESTRICT );
INSERT INTO school (school_name) VALUES ('Alice''s School of Truck Driving'); INSERT INTO school (school_name) VALUES ('Bob''s School of Underwater Knitting');
INSERT INTO student (student_name, school_id) VALUES ('Charlie', 1); INSERT INTO student (student_name, school_id) VALUES ('Doug', 1); INSERT INTO student (student_name, school_id) VALUES ('Ernie', 2);
Note the 'ON DELETE RESTRICT' which will prevent you from deleting a school if there is a student going to that school. First look at what's in the tables:
SELECT * FROM school; SELECT * FROM student;
Now attempt to delete the school:
DELETE FROM school WHERE school_id = 1;
If you try the above, you should see 'ERROR: school_exists referential integrity violation - key in school still referenced from student' and notice that nothing was deleted.
If you want to try the above more than once, the following may be handy: DROP SEQUENCE school_id_seq; DROP TABLE school; DROP SEQUENCE student_id_seq; DROP TABLE student;
Cascade & Update Instead of 'ON DELETE RESTRICT' you could specify 'ON DELETE CASCADE'. This would allow the delete (instead of preventing it like in the example above), but it would 'cascade' the delete to the student table so that any students going to the school you deleted would also be deleted.
As well as the 'ON DELETE ...' clause you can also specify what is to happen on an update of the foreign key with either:
a.. ON UPDATE RESTRICT or b.. ON UPDATE CASCADE ON UPDATE RESTRICT would prevent UPDATE school SET school_id = 20 WHERE school_id = 1 from proceeding if there were any students with a school_id of 1.
You might be able to guess that ON UPDATE CASCADE would allow the UPDATE school SET school_id = 20 WHERE school_id = 1 to proceed, but it would also update the school_id field in the student table appropriately.
Foreign Keys where the field names are different Consider the following table setup:
CREATE SEQUENCE school_id_seq; CREATE TABLE school ( id INT NOT NULL PRIMARY KEY DEFAULT nextval('school_id_seq'), name VARCHAR(80) NOT NULL );
CREATE SEQUENCE student_id_seq; CREATE TABLE student ( id INT NOT NULL PRIMARY KEY DEFAULT nextval('student_id_seq'), name VARCHAR(80) NOT NULL, school_id INT NOT NULL, CONSTRAINT school_exists FOREIGN KEY(school_id) REFERENCES school(id) ON DELETE RESTRICT );
INSERT INTO school (name) VALUES ('Alice''s School of Truck Driving'); INSERT INTO school (name) VALUES ('Bob''s School of Underwater Knitting');
INSERT INTO student (name, school_id) VALUES ('Charlie', 1); INSERT INTO student (name, school_id) VALUES ('Doug', 1); INSERT INTO student (name, school_id) VALUES ('Ernie', 2);
Note how the field names don't match (school.id as opposed to student.school_id); in this case we can put the field name in brackets after the table name.
As before, the following will fail:
DELETE FROM school WHERE id = 1;

Hi, All.
I have to build a web site and I was studying postgreSQL, but, whether I am quite wrong or this database does not support Foreign Key.
Does anyone use postgreSQL and know how handle Foreign Keys ???

When I call this function:

I do get the correct result printed to the browser ... So what the HELL is going on? Dont tell me that pass by reference doesnt work with pg_* functions? Just to test this, I did this:

For the phpPgAdmin users, if you might help!!!....
I am running PostgreSQL 7.1 over RedHat.
When trying to connect through the web everything goes right. A script that is currently working:
<?php
$link = pg_Connect("host=localhost port=5432 dbname=teste") or die ("Could not connect");
$comando = "select * from teste"; $result = pg_exec($link,$comando); $linhas_retornadas = pg_numrows($result);
echo "<table><td><b>nome</b></td><td><b>sobrenome</b>"; for ($i=0; $i < $linhas_retornadas; $i++) { $row=pg_fetch_array($result,$i); echo "<tr><td>" . $row["nome"] . "</td>"; echo "<td>" . $row["sobrenome"] . "</td></tr>"; } echo "</table>";
pg_close ($link); ?>
All *my databases are owned by user 'postgres'* and I had to create another PostgreSQL *user 'apache' and give ownership of table 'teste' in database 'teste' to this user* (apache) in order for this connection to work.
My 'pg_hba.conf' file reads: local all trust host all 127.0.0.1 255.255.255.255 trust
With phpPgAdmin I configured file 'config.inc.php' as follows:
// The default database is used to connect to the database to check the adv_auth // This can actually be any database you currently have on your system. It just // needs _a_ database to connect and check the system tables. $cfgDefaultDB = "teste";
// You should change the superuser if different from postgres // This is just used to filter out the system functions when listing $cfgSuperUser = "postgres";
// Set to true if you want to authenticate against the passwd as well as the username // In order to use adv_auth, you must update the passwords in the user admin section. // It is suggested that you leave this as false until you are able to get in and update the passwords. $cfgUsePass = false; $cfgServers[1]['local'] = true; $cfgServers[1]['host'] = 'localhost'; $cfgServers[1]['port'] = '5432'; $cfgServers[1]['adv_auth'] = false; $cfgServers[1]['stduser'] = 'apache';
No matter if I set $cfgServers[1]['host'] as 'localhost' or as '127.0.0.1' $cfgServers[1]['stduser'] as 'apache' or as 'postgres' or as none
No matter what I always get a blank Web page with the following messages:
================ ERROR The requested URL could not be retrieved
While trying to retrieve the URL: [no URL]
The following error was encountered: Zero Sized Reply
Squid did not receive any data for this request. Your cache administrator is webmaster. Generated Sun, 04 Mar 2001 23:15:30 GMT by internet.gst.com.br (Squid/2.3.STABLE3) ================
Please help!!! This shall most probably be some problem of permission, but how do I manage to make phpPgAdmin to correctly connect and access my databases?

Have a look in the String Functions section of the manual. In particular, substr_replace, str_replace or strtr. Also the Regular Expressions section if you want more complex replacement capabilities.

Yes you can. Include a field in your db called 'date' or whatever.
Generate the date in your script using:
$today = date("Y-m-d");
Then simply add the date to the db along with everything else. There are lots of ways to format dates, too many to describe here. Have a look at the PHP manual. Also, if you make the data-type of the date field 'date', your options for formatting are more limited. That stuff is all in the MySQL manual.

If you make the field in the database of type "DATETIME" then you can insert dates and select formatted date values using MySQL's date and time functions. (I assume you're using a MySQL database.) There is no need to use PHP's date functions.
Examples:
CREATE TABLE mytable ( ... mydate DATETIME, ... )
To insert the current date, use NOW() as the date value:
INSERT INTO mytable VALUES (..., NOW(), ...)
To select the date formatted as "Saturday March 5th 2001 12:30 PM":
SELECT col1, col2, DATE_FORMAT(mydate, '%W %M %D %Y %r') AS mydate, col4 FROM mytable

Hi!
I wrote this simple function to return the current date minus supplied number of years:
function get_birthdate($age_in_years) { // get the current timestamp into an array $timestamp = time(); $date_time_array = getdate($timestamp); $hours = $date_time_array["hours"]; $minutes = $date_time_array["minutes"]; $seconds = $date_time_array["seconds"]; $month = $date_time_array["mon"]; $day = $date_time_array["mday"]; $year = $date_time_array["year"]; // use mktime to recreate the unix timestamp // subtracting age_low and age_high from the years $timestamp = mktime($hours, $minutes,$seconds ,$month, $day,$year - $age_in_years); $birthdate = strftime("%d/%m/%Y", $timestamp);
return($birthdate); }
You, obviously, call it like this: echo get_birthdate(1); Which would return a datestring that looks like this: 05/03/2000
Works nice, but the problem occurs when I try to subtract more than 31 years which is naturall since, as far as UNIX is concerned, the world didn't exist then. (Took me a while to figure this one out though.)
Any clues on how to fix this so that I can go beyond the past 31 years?

Then you could do this:
$myclassObj = new myclass(); $myclassObj->setmyvar(10); echo $myclassObj->myvar;
This would print '10'...
Cut and paste that exact program in and it should be a working demonstration ...

No, you cant do this as you coded it, however minor alterations will allow this. Last time i checked, you couldnt initialise variables in object scope ... you can only declare them. This makes sense, because thats what the constructor is for.
Altered code for what you want to do is as follows:
class myclass{ var $fields; var $columns;
function myclass { // constructor $this->fields = mysql_list_fields("database1", "table1", $link); $this->columns = mysql_num_fields($fields); }
// all code must be declared in a function !! - This isnt Java Script :) function doSomething() { for ($i = 0; $i < $this->columns; $i++) { var mysql_field_name($this->fields, $i); } }//function doSomething() }//class
$myobj = new myclass(); // creates object and runs constructor (see above) $myobj->doSomething(); // do whatever you want the object to do

Greetings !
I am using PHP4 and MySQL for database in the web. I am using two tables. I made a search script for one table which displys the list on the web page and want to put a link in one of the fields on that web page so that the link takes browserts to the data of the other page.
I could not achieve this function. Can anyone help?
Looking forward to hearing from you.

Two things that may or may not be part of your problem;
first, if there is already something in $headers then appending the cc to it may give you an invalid string; and
second, you might try Cc: instead of CC:

$testvar means "the value of the variable named 'testvar'".
$$testvar means "the value of the variable with the name of the value of 'testvar'". ie - testvar is "foo", $$testvar is equivalent to $foo.

I'm trying to read in a text file that has 42620 lines. Each line has zip code information separated by commas. I have no problem reading the file into an array. But when I try and read each element in the array and put it into another array I get a "500 server error". The second to last line is what's causing the problem.
After doing some debugging I found out that at around iteration 18000 is when the server error occurs. Any ideas? I know I should use a database, but i'm intrigued by this problem.
Here's the code that does the work...
# read the file in, each line in the file is it's own element in the array $lineArray = file( "zips.txt" );
# initialize variable, showing that there's nothing in $ZIPS $ZIPS = array();
# iterate through each element in the array, foreach() is probably cleaner for($i = 0; $i < count($lineArray); $i++ ) { # set variable $value = $lineArray[ $i ];
# set $tempArray to a new array $tempArray = array();
# convert the line into an array $tempArray = explode( ",", $value );
# add the line to the array in the format # $ZIPS[ "zip code" ] = array( "zip code", "state", "city", "lat", "long" ) $ZIPS[ $tempArray[ 0 ] ] = $tempArray; }
Thanks in advance.

Yes, this is a problem with IE. A lot depends on how IE is configured and exactly what shortcut users are using to start IE.
In IE's Tools > Internet Options > Advanced tab, make sure that the "Launch browser windows in separate processes" option is checked.
DO NOT use Ctrl + N to start up a new IE window - that way users will not get prompted for passwords.
Using any other shortcut to start IE should make it prompt for password.
All of the above is based on my experience with IE 5.0 but should be equally applicable to IE 5.5.
