Can anyone help me with this problem please!
the code below shows a football fixture for the entire season , round 1-22
but this takes up to much space on the webpage (very long page).
Is it possible to display one round at a time so its automatic.
At the moment- each week the admin closes a round ie: (round 2 closed) so i
want the page to display round 3 fixtures only for the entire week.
Can a script show the next round after the closed round (if round 1 is
closed go to next round -2- if thats closed go to next round which is 3,
until it gets a round thats not closed and shows the results.

Re: [PHP] Re: umlaut problem in firefox
meta http-equiv=Content-Type content=text/html; charset=iso-8859-1 This is in the header. If I look at page info in firefox I get: text/html; charset=iso-8859-1. So the setted encoding is correct. The problem that I noticed is that the umlauts are displayed correctly but when I submit them in the POST or GET array I receive them modified. This happens on 2 different servers. The same behavior. Apache2 + php5. With php4 I didn't have this problem. The really stupid thing is that sometimes works well.

Re: [PHP] Creating a unique index ID
tedd wrote: Hey all, I've got a project where I'm taking form information from the user and writing records to several tables in a MySQL database. The problem I'm having is I need to write a unique number for the ID column of the records. Auto increment won't work because I could have conflicts due to replication of the database servers. Anyone have any techique they use for creating unique ID field entries in a db table? I was thinking maybe using a random 3 digit number and a unix timestamp? Jeff Jeff: Look into getmypid() and uniqid() or combine the two. How about using a DB abstraction layer that provides its own method of implementing sequences?

Re: [PHP] setcookie security concerns
If this is the value directly from the cookie, it's an example of a
cross-site scripting (XSS) vulnerability.
header(Location: $HTTP_REFERER);
This is an HTTP response splitting vulnerability, because the Referer
header (like the Cookie header) is provided by the client. Future
versions of PHP will not allow more than one header per header() call,
but this has been possible until now.
3. If so, what do I do to correct this?
Don't trust any input without inspecting it first. In your case, this
is particularly easy, because you can just make sure that the value is
one of the few valid values.
Hope that helps.
Chris
Chris:
Yes, it helps and I thank you for your comments.
Your question: It's not entirely clear from this example, but am I
correct in assuming that $thestyle is the same as $_COOKIE['thestyle']
in this case? In other words, are you relying on register_globals or
assigning the value yourself?
The example is here:
http://www.sperling.com/examples/styleswitch/
The complete php code (i.e., switch.php) is:
?php
setcookie ('thestyle', $set, time()+31536000, '/', '', 0);
header(Location: $HTTP_REFERER);
?
And the value is assigned by the user via a click:
a href=switch.php?set=style2Green/a or a
href=switch.php?set=style1Red/a
And, the style sheet is determined by:
link rel=stylesheet type=text/css media=screen href=?php
echo(!$thestyle)?'style1':$thestyle ?.css
As such, I am expecting the user to provide the value of 'thestyle' via
his choice.
However, let's say a malicious user would try to do something -- what
could he actually do?
The user could insert arbitary HTML where you have the variable. For
example they could insert:
style1.cssscript language=JavaScript
type=text/JavaScript.../scriptmeta name=bye content=
This would allow them to run arbitary javascript on the clients computer.
An interesting question in this case is how to do an injection using
cookies, injection attacks are generally performed using post get data
as they can be inserted to a link on another page. Getting a working
exploit would probably come down to how the browser implemented the
cookie security; who can set cookies where.
Regardless, it's not worth the risk. Checking for valid values or using
htmlentities to make the variable safe is a quick and simple solution.
Getting into the practice of screening all user data either manually or
using the input_filter extension will also save you from these problems
in the future.

Re: [PHP] Hostname Filtering
The hostname lookup does not impact performance at all. I am only doing a look-up on the remote ip of the user not on my full blacklist. I am using this on a site to log hits to a banner ad and on listings on a ebay style marketplace. I log the IP and the hostname on a look- up. Dan T On Mar 14, 2006, at 11:30 AM, Philip Hallstrom wrote: I have a few PHP scripts where I log hit to a page i.e. IP and hostname via a look up. What I want to do is create essentially a blacklist to prevent bots and other hosts and IP from being logged and skewing my stats. My local IP/host and the MSN and Googlebot hits should not be in my stats or at least I can flag them to hide them. For example: $blacklist = array( '*.wavefront.ca', '*.googlebot.com', 'msnbot.msn.com', '*.inktomisearch.com', '68.146.96.245' ); So lets say I have my host: $host = 'lj602144.inktomisearch.com'; I want to quickly parse this array and return a simple boolean if I am in the blacklist. I could create a loop and cycle through the array valves and to a regex on each but I was hoping someone would have a more elegant solution. http://us3.php.net/in_array You might want to rethink things though... if you list hostnames you're going to have to do a DNS lookup for *every* request to that script.

RE: [PHP] to check idle time of users
Miles, Please do not scare away people from the list. There can be many reasons why he asks this question without looking at the documentation first. 1: He/She is maybe new to this subject, and do not have a lot of experience with reading docs. 2: He/She maybe don't have English as mother language that will make manuals difficult to understand etc. In the beginning of my life in the PHP and web programming world, I found the docs extremely difficult to understand. You learn by doing, and this is maybe his way to start to learn. If you find this so Fergawdsake, just ignore it, someone else might see this in a deeper way then you seem to do.

Re: [PHP] Re: umlaut problem in firefox
My problem still remains open Help!!! I noticed that if the umlauts are received correctly but they are not submitted in the right way. For a ö I receive a POST as: ö From the DB I get the text correctly. meta http-equiv=Content-Type content=text/html; charset=iso-8859-1 The DB encoding is : iso-8859-1. Now, the strange thing is that is does not appear ALWAYS and only sometimes and only in firefox. So.. I cannot really reproduce the error every time which is hard to debug. As Barry said, the is a Unicode UTF-8 encoding. So, instead of charset=iso-8859-1 it should be charset=UTF-8 Then, I suggest you look-up the code-point of the character you want to use and remember that code-points (HEX) don't work in html (DEC), so you'll have to make that translation to display them.

[PHP] [NEWBIE GUIDE] For the benefit of new users
= Please feel free to add more points and updates. 20050322jb - Note the new location of PHP Editors list. = Topics: === - Where to Find More Information - Diagnosing the problem. - Some Quick Guidelines on Posting - Contributors to this document Where to Find More Information === If you have any queries/problems about PHP, the online manual (you can get an offline copy as well) is a good tool to become familiar with. http://php.net/manual Some Key sections of the PHP Manual: - Installation and Configuration http://php.net/install - Language Reference http://php.net/langref - Function Reference http://php.net/funcref tip: if you know the function name but forget exactly how it works just type the name of the function ie: http://php.net/array_merge - The PHP FAQ http://php.net/faq Try http://www.google.com/ Searching for php YOUR QUERY may fetch you relevant information within the first 10 results. There is a searchable archive of the mailing list discussion at http://phparch.com/mailinglists. Many of the common topics are discussed repeatedly, and you may get answer to your query from the earlier discussions. For example: One of the repeatedly discussed question in the list is Best PHP editor. Everyone has his/her favourite editor. You can get all the opinions by going through the list archives. If you want a chosen list try this link: [1] http://www.thelinuxconsultancy.co.uk/phpeditors.php Diagnosing the problem. == Not sure if PHP is working or you want find out what extensions are available to you? Or you're not sure exactly how php is configured? Just put the following code into a file with a .php extension and access it through your webserver: ?php phpinfo(); ? If PHP is installed you will see a page with a lot of information on it. If PHP is not installed (or not working correctly) your browser will try to download the file. One useful trick is to print the variable that you are having troubles with using print or echo command and check whether you get what you expected. PHP is a server side scripting language. Whatever processing PHP does takes place BEFORE the output reaches the client. Therefore, it is not possible to access users' computer related information (OS, screen size etc) using PHP. Nor can you modify any the user side settings. You need to go for JavaScript and ask the question in a JavaScript list. After diagnosing the problem, send the details of your efforts (following 'Where to find more information') and ask for help. Some Quick Guidelines on Posting === - Provide a clear descriptive subject line. Avoid general subjects like Help!!, A Question etc. Especially avoid blank subjects. - Don't just state it doesn't work, be descriptive in why you don't think it works. - Don't send you're 200+ line script to the mailing list and expect an answer to why line 198 doesn't work. If you need to post a large amount of code, provide a link to a page that shows the code, or use a pastebin site like: http://www.pastebin.com/ - When you want to start a new topic, open a new mail composer and enter the mailing list address php-general@lists.php.net instead of replying to an existing thread and replacing the subject and body with your message. - When replying try to include the mailing list with the reply, unless of course it is personal. A common way is by using your email/news readers' reply to all functionality. - Compose your message in a format that everyone will be able to read. This means that it would be best to send your message in plain/text format. If you do send in HTML be sure to send your message that includes a plain/text format. - It's always a good idea to post back to the list once you've solved your problem. People usually add [SOLVED] to the subject line of their email when posting solutions. By posting your solution you're helping the next person with the same question. - Ask smart questions http://catb.org/~esr/faqs/smart-questions.html - More on the traditional netiquette. Although the following suggestions have been known to be debatable they should help you in general internet mailing list a. Please do not top post as it is hard to follow. If you are unfamiliar with the concept it is the posting of the reply ABOVE the thing that is being replied to. b. When Replying. Where possible trim your posts so that only relevant portions of the message are being discussed. Replies that become too lengthy are likely to be ignored. Following these guidelines will ensure that you get effective responses from the list members. Otherwise, your questions might not be answered. Contributors to this document
[PHP] REG-EXPR: Allowing limited number of special chars in usernames
Hello,
I dont know that much aboput regular expressions and just want to know how to
find out the number of special (non alphanumeric) characters in a string or how
to match a string that contains less than 3 special chars.
urrently im using a function
function valid_username($string) {
if(strlen($string)=16strlen($string)5) {
return(preg_match('/^[ -~äöüßÄÖÜ]+$/',$string));
} else {
return FALSE;
}
}
This allows usernames of 6 to 16 length containing many special chars and
German Umlaute.
But this also allows usernames like =)/(%$ what should not be.
So how to limit the number of special chars? This function should just return
fals if number of special chars X

One thing that comes to my mind would be splitting up the string into
letters, numbers and signs with ereg()/preg() and count each one.

It's more likely that you've got whitespace before or after the
region, especially if it's the last in the list that's always failing.
Try trimming the region before passing it to in_array().
Have you ever considered using braces around loop blocks?

GIF's don't do very well with some images as it can't encode them very efficiently. I don't remember which way it goes, but a 1x500 gif of a solid color will be much much much larger than a 500x1 gif of a solid color. The latter it can compress by sayign something like x color for the next 500 columns on this row.

For practical reasons it is currently not allowed to have .. components in the path to the executable. Could this be your problem? James This version of php doesn't have a php.ini file for configuration, so there's no safe_mode_exec_dir. I tried to create the one mentioned in php_info() and copy the executables there but it didn't work. Nelson Carreira Hmmm. I'm all out of ideas.

[PHP] regular expressions and Phone validation
Hi all,
I have one small problem I don't understand the preg_replace() method.
I understand the gist of what it does but I still don't fully know
what it does. I have read the entry in the php manual about this and
I am still confused about it. I've never been any good with regular
expressions.
Here is the function in use:
function checkPhone ($Phone)
{
global $errmsg;
if (!empty($Phone))
{
$Phone = ereg_replace([^0-9], '', $Phone);
if ((strlen($Phone)) = 14)
return
preg_replace(/[^0-9]*([0-9]{3})[^0-9]*([0-9]{3})[^0-9]*([0-9]{4}).*/,
(\\1) \\2-\\3,$Phone);
}
}
I think my problem is mostly what is returned when preg_replace executes?

Re: [PHP] PHP/Oracle : bug with accent...
I have a big problem with my Debian server (Apache 2, PHP 5, Oracle Instant Client). I've modified the environment variable NLS_LANG and, with SQL*Plus, everything is ok ! But, in a PHP page, I can't insert a value with accent (ex: Irène). I can read data with accent, but not inserting !!! I searched all the afternoon, testing many solutions, without success. I think I'm not alone with this problem but... Do you have any clue ? Something to look at ? Try looking at the multi-byte string functions. Not sure if that would help you or not though. OK. I've finally found the solution. Everything was ok except the Apache environment variables (NLS_LANG). Now, it works... Thank you.

[PHP] Class Variable Scope Question
Hi Guys,
I am wondering how to be able to call a class variable from within an
outside function using the :: syntax: See an example of the logic I
am using below:
class myClass {
var $variable = 1;
function showVar() {
return $this-variable;
}
}
$obj = new myClass;
function extFunction() {
return myClass::showVar();
}
I am assuming this isn't working because by calling myClass::showVar
() instead of $obj-showVar() $this would be undefined...does
anyone know how to workaround this (e.g. direct access to a variable
via :: syntax like myClass::variable). Does PHP5 address this at all?
Many thanks on this.

[PHP] Re: Creating forms dynamically
Hello, on 03/14/2006 05:21 PM Paul Goepfert said the following: I have been working on a page where I have a form. I currently have the form in an else block with no access to it if I need to redisplay the form incase of errors. To be more specific I want to redisplay the page with the errors displayed. I would like to have the form coded once. It would save on file size. In my form I have a table that holds the text inputs. I do have MySQL code for dropdown menus. If anyone has any ideas on how to create the form when the error messages are displayed without having to code it a second time please let me know. Why don't you just use the same script to display and process the form? Just set the form action attribute to an empty string and you do not even have to figure what is the current page URL. I always do that precisely for the reasons you mentioned of the form having invalided fields that need to be corrected by the user. I also use this popular class for forms generation and validation. I just specify which kinds of validation I want and the class validates the form for me on the server side. It also generates automatic Javascript code to perform validation on the browser side before the user submits the form to reduce the need to access the server to perform validation. Now there is even something better. The class comes with an AJAX form submission plug-in that lets the form be validated without reloading the page. If there are invalid fields, your script can command the forms class with that plug-in to mark the fields that are invalid. If the form is completely valid, you can process the form actions and give feedback to the user browser while the form processing occurs on the server side. When all is done you can tell the class to show a success message, wait a few secons and redirect the browser to a new page. The good part is that this works well with all browsers and you do not need to know a single bit of Javascript to implement this. Take a look in particular to the test_ajax_submit.php example. http://www.phpclasses.org/formsgeneration PS. the class also comes with another plug-in to link multiple dropdown (select) inputs loading options taken from a database. http://www.phpclasses.org/browse/view/html/file/9879/name/test_linked_select_page.html -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If anyone has any ideas on how to create the form when the error messages

I use an assoc. array that matches the form inputs, for example:
$FormDisplayData = array(
'username' = '',
'email' = '',
'city' = ''
);
and a flag variable that is set when an error is encountered.
Then in the form:
echo Enter your username: input type=\text\
name=\username\
value=\{$FormDisplayData['name']}\;
if ($FoundErrors) { echo Invalid username!;}
and so on.
This way, first time through the form the array is empty and the error flag
is false - user gets a form ready to be filled in. If you get a processing
error, populate the $FormDisplayData array with the values from $_POST, and
the user gets his input back to correct, and a message telling him why.
Neat, huh?
There are undoubtedly many other ways to do this, but this is the only one I
know :)
Hope this helps.

The main requirement I have is I need to be able to use the existing user logins to access the forums. I also need a help desk ticket system that is also linked to the same users. I may however write that one myself as it doesn't need to be very sophisticated. Can some one recommend a php forum package and possibly a help desk ticket system that would be easy to integrate with my existing system? Basically what I will need to do is know how the account creation works with both systems and have my existing site populate the DB tables of each system and my existing login system set cookies or other variables so when they are logged into one they are logged into them all. Look for one that has a developer api you can use to create / update users, it will make things easier (come upgrade time it won't change too much either whereas a database can change considerably and all your work goes down the drain). Apart from that you'll need to modify each system so if you log in to the ticket system, you are logged in to the forums, if you log in to the website, you are logged in to both and so on - so the code will need to be open (unencrypted). -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] HIgh score not up to scratch
Any help Here:
At the moment this shows a USERNAME-COMPETITION and POINTS for a user with
the highest points out of many competitions.
The USERS also have a second points field (acc_margin) where lower score is
better.
So my problem is that i need to show the highest scoring user (by points)
then if there is another user with the exact same points then the user with
the lowest (acc_margin) is shown.
?php
for ($x=1; $x=$no_comps; $x++) {
$max_query[$x] = mysql_result(mysql_query(SELECT MAX(points) as Num
FROM leaderboard WHERE comp_id = $comp_ids[$x]),0);
//get name
$query4 = @mysql_query(SELECT username FROM leaderboard WHERE points =
. number_format($max_query[$x],0) . AND comp_id = $comp_ids[$x]);
$result4 = @mysql_fetch_array($query4);
$leader[$x] = $result4['username'];
//get comp name
$query5 = @mysql_query(SELECT name FROM comps WHERE id =
$comp_ids[$x]);
$result5 = @mysql_fetch_array($query5);
$comp[$x] = $result5['name'];
echo tr class=tdb1td . $leader[$x] . /tdtd . $comp[$x] .
/tdtd align=center . number_format($max_query[$x],0) . /td/tr;
}
?
HERE IS THE TABLE:
Field Type Null Default
id int(11) No
user_id int(11) No 0
comp_id int(11) No 0
username text No
points int(11) No 0
amt float No 0
margin int(11) No 0
acc_margin int(11) No 0
I had a similar question earlier that i was helped with but i cant seem make
it work here:
(here it is)
SELECT * FROM leaderboard WHERE comp_id = $comp_id ORDER by points DESC,
acc_margin ASC

Re: [PHP] Is this password protection script secure?
Oscar Gosdinski wrote: Instead of using a hash if the password string, i prefer to save the following in the password field of my user's table: md5($user . $password) This is a good idea, IMHO of course. There are some md5 databases around that can be used to get the cleartext password from the hash if your database is compromised, if you use this method it's difficult to get the cleartext password because it depends on the user and you are also validating if the user exists. Well, it's a little hard to obtain the cleartext from something in MD5-hash, though it's possible via brute-force. You might as well try to use some other method, such as SHA1, combine them or do whatever you want to alter the initial clear-text version to obfuscate it (like you did above) However, i have a question. Which is better?, the md5 function provided by PHP or MySQL? i used the MySQL function because i didn't compile PHP with support for hash. The one in JavaScript :) AFAIK, every MD5 function is based on the MD5 algorithm, so the implementation is rather similar (if not the same) Of course, the result is always the same. -- Atentamente, J.

[PHP] Re: setcookie security concerns
As far as I see... I can't see any risk. Cookies are saved in the
client machine (i.e. the one visiting your site), so any code he might
send will be used with him only, and it will not affect other users nor
the scripts in the (remote) server.
Now, you're not using the input value in anything similar to an eval()
expression, hence should some PHP code be sent and it would only be
printed, no harm in that either.
Inspite of all this, I would really recomend you not to rely on
register_globals=On, since: it's not a good idea, it's actually
deprecated (someday it will be removed) and makes your code a little bit
more confused, since it's not clear where do that variables come from.
1. Is he right?
Yes, and no. In your specific case someone _could_ send you code
instead of whatever you're expecting (and you don't validate the input),
but it would be harmless for anyone other that himslef.
Beware that the risk of code inserted in cookies, form-input elements,
the Query string, etc., is real and it depends on the way you use the
data received, and if you check it and how do you do it.
2. How does that work?
Well, cookies are stored in your (client) machine, so you're able to
modify whatever content they have. One way to test this is using
Firefox and an extension that allows you to edit cookies such as Add N
Edit Cookies (play with the cookie of your own site)
3. If so, what do I do to correct this?
Do not rely on register_globals, and don't ever trust on any input
given by the user, treat all of them as enemies and check everything
that comes to your mind --and more ;)
Note: this is how _I_ see it, so I could be ignoring something that
other people did see.

Within the body tags, allowing the user to select which style they want:

And, the corresponding (switch.php) php code is:

It's pretty simple. But recently, I had one person hammer me stating it

such, he says that someone could inject an arbitrary code and cause
problems.

Holger Sunke wrote:

I don't really understand what you need, but...
- how to find out the number of special (non alphanumeric) characters
$alpha = '[a-z0-9]';
$special_chars = preg_replace(/$alpha+/Xi, '', $string);
* this would replace any alpha-numeric char by... nothing, leaving
the special chars only, and strlen() will give you how many are
* beware that you're saying *anything* other than alpha-numeric chars
- how to match a string that contains less than 3 special chars
* as I said above, strlen() will give you the number of these chars:
$num_special_chars = strlen($special_chars);
preg_match('/^[ -~äöüßÄÖÜ]+$/',$string)
will return TRUE if $string consists enterily of the chars between the
square-brackets.
I hope this helped a little.
urrently im using a function
function valid_username($string) {
if(strlen($string)=16strlen($string)5) {
return(preg_match('/^[ -~äöüßÄÖÜ]+$/',$string));
} else {
return FALSE;
}
}
This allows usernames of 6 to 16 length containing many special chars
and German Umlaute. But this also allows usernames like =)/(%$
what should not be.
So how to limit the number of special chars? This function should
just return fals if number of special chars X

[PHP] Re: regular expressions and Phone validation
Paul Goepfert wrote:
I have one small problem I don't understand the preg_replace() method.
I understand the gist of what it does but I still don't fully know
what it does. I have read the entry in the php manual about this and
I am still confused about it. I've never been any good with regular
expressions.
Well, I'm not sure about what you don't understand. Anyway,
preg_replace() does the same as str_replace(), but using
regular-expressions instead of just strings. If you understand how do
reg-exp work, then it should have no real problem, if the reg-exp are
the problem then you better read a little more about them (the PCRE
tutorial at php.net is really good, IMHO)
Here is the function in use:
function checkPhone ($Phone)
[···]
$Phone = ereg_replace([^0-9], '', $Phone);
if ((strlen($Phone)) = 14)
return
preg_replace(/[^0-9]*([0-9]{3})[^0-9]*([0-9]{3})[^0-9]*([0-9]{4}).*/,
(\\1) \\2-\\3, $Phone);
[···]
I think my problem is mostly what is returned when preg_replace executes?
Well, what's inside parenthesis is remembered by preg_replace(), and
you make reference to them using \\n or $n (where n is a number)
in the replace-string (there are some exceptions, but that should do
for now) If you look carefuly, there are three expressions between
parenthesis, and these are what you're referencing via (\\1) \\2-\\3
Though, there's something I don't get it: in your reg-exp your ignoring
any non-numeric character, but you already got rid of them with
ereg_replace()... (??)
