Following is a snippet of code that I am trying to debug. Most of the
time, the variable $sn (set on the last line), correctly contains the
variable $this_customer_num. On some occasions, however, it does not
contain $this_customer_num. I cannot figure out what may be happening
that this value is missing around 1-10% of the time.
?php
$memberchecker=mysql_query(SELECT id, password, customer_num FROM
logins WHERE email = '$email' );
//email is unique and not null
if (!$memberchecker) {
//handle error
} else {
if (mysql_num_rows($memberchecker) = 1) {
while ($row = mysql_fetch_array($memberchecker)) {
$this_login_password=$row[password];
if ($this_login_password==$password) {
//$password is a form variable (yes register_globals is
on...*sigh*)
$this_customer_num=$row[customer_num];
$companycheck=mysql_query(SELECT priority, cash_price
FROM customers WHERE customer_num='$this_customer_num'); //customer_num
is primary key, so unique and not null
if (!$companycheck) {
//handle error
} else {
if (mysql_num_rows($companycheck) == 1) {
while ($cow = mysql_fetch_array($companycheck)) {
$id=$row[id];
$priority=$cow[priority];
$cp=$cow[cash_price];
$sn=date(Sz).$this_customer_num.time();
?
Before anyone yells at me, no I did not write this code. I first
thought there might be a problem with the array keys not being quoted,
but if that were the case, and an empty string were assigned to
$this_customer_num, then I should not be able to pass the second query,
since there are no empty string customer_num entries (all of them are at
least 9 characters in length).
I have been unable to reproduce an instance where $sn is missing the
$this_customer_num variable, and I'm stuck in a kind of political
situation where I can only make recommendations, and not change the code
myself.
Suggestions on where to start looking? Thanks in advance.

[PHP] Japanese Fonts in php
Hi All, how would one get them to display in php pages..? Is it like ASP where you have to set a codepage number..? I've set this at the top of my pages, html lang=Shift_JIS and this for the font font type=\Shift_JIS\$product_data_output/font I don't claim to know much about HTML either. I'm just building a little dynamic site for my company, minus any bells and whistles interface wise. Do I have to set something in php/apache for this.? Thanx.

$companycheck can easily be non-false and contain no rows. A query that
doesn't match any rows is not a failure, it is simply an empty result
set. So you wouldn't get into the //handle error code there and your
mysql_num_rows() wouldn't be 1. This would appear to be possible if
there was some sort of mismatch between the customer ids in the login
table and the customers table. A bit more error checking should make it
obvious.

Re: [PHP] How to confirm subscriptions by e-mail on a PHP site ?
Hi George, Thank you for your answer. The future users of the site i'm doing can register freely. No need for aproval. I just want to ensure that there are no fake subscriptions or fake e-mails. I was thinking more in something like an email sent back after the form fill, with an URL back to the site that makes the conformation. I'm doing some experimentations on this field. When they fill in the form, all data goes to the DB along with a random generated code. There's a boolean field called confirmed, that has an obvious job, i. e., defaults to FALSE. After that, i send them a mail with an URL ending in ?code=345njkh53h23 If they click on them and the codes match, the boolean field in the DB switches to TRUE. I think it's a bit complicated engine for such a simple field. Any sugestion about easying the process ? Warm Regards, Mário Gamito George Pitcher wrote: Mario, My site is for universities. Each university has their own administrator, responsible for authorising each of their own subscribers. No that is probably overkill. However, when a new subscriber registers (simple data gathering form - including preferred password), the system sends off an email to the appropriate administrator, who logs in, awards access level (we have 5 different access levels) and then an email is sent to the new user confirming all the details. So you could have the response to the data gathering form, record the info in a db and then send an email to the new user. I also have a small form on the login page that if the user enters their email address, and its the one they registered with, it sends their login details inc passwords to that email address. Saves me having to sort it out. Hope this helps.

Does anyone sugests a simple, yet effective way to do this ? When the user subs, generate a token in a DB table. Send the token to the user via email with a URL to click. Use mime/alternative if you want to send html and plain text so their client can choose the rendering method. If you get the click where the token matches (and perhaps first name or similar), they've confirmed their desire to subscribe. Do what you need to do with the confirmation and remove the token from the table. Record a history of IP etc to show that they DID indeed confirm their sub. Gives you proof that they asked for it if they contend it's spam. -- My mind not only wanders, it sometimes leaves completely. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Your code seems non-sensical to me. There are lots pf considerations to take

what I think you're after:
$sql=select User_pass from user where user_name = $_POST[user_id];

$row=mysql_fetch_array($result);

Re: [PHP] How to confirm subscriptions by e-mail on a PHP site ?
You can either email them an URL containing an activation code, which would have them activate in their browser. If you don't understand the terms .forwared, or MTA, you should probably either learn more about them or skip to the third paragraph. If you want them to activate using their email client, the question isn't quite(although almost) so simple. You can either use the .forward mechanism, to parse the response mail, and deal with it accordingly(assuming you're using a .forward capable MTA). Alternatively you can have them reply to an account, and set up a cron job(assuming you're on unix) to have PHP check the account using it's imap functions every minute. The first way would be preferable.

email with a link that they must click to validate their email:
http://www.mysite.com/[EMAIL PROTECTED][EMAIL PROTECTED]

Its not foolproof, I know, but it is simple and effective, as you say.
Heres a quick and dirty function to generate the key:
function KeyGen($length){ // Generates random, mixed case, alphanumeric
string of $length characters.
for($len=$length,$r='';strlen($r)$len;$r.=chr(!mt_rand(0,2)?mt_rand(48,57):

Re: [PHP] How to confirm subscriptions by e-mail on a PHP site ?
The way i did it was, put a 25char hash inside the registered column,
then sent an email to the user containing something like
domain.com?user=id_numberhash=hash
then i did select userID where userID = $_GET['user'] registered =
$_GET['hash']
(not exactly the sql phrase, but i dont feel like adding %s's and
mysql_real_escape_strings to it but you get the picture)
then from the data i got, i did
if($row_is_returned)
{
update users set registered=yes WHERE userID = $_GET['user'];
}
and that was it.

Regards Emil If I understand you correctly, a person orders a kit, you print a barcode, on a sticker for instance, and apply it to the kit they order. You then want to be able to scan the barcode, when you ship it for instance, back into the application. For this you will need a TTF barcode font (available on the web for free), a barcode scanner (check out Symbol, and Wasp), and a label printer. There are many, relatively inexpensive, barcode reader solutions that simply plug into a USB port, or go between your keyboard and your computer. Scans data in just as if you had typed it.

Re: [PHP] Bar codes

Regards Emil I've written an entire Warehouse Management System using PHP that utilizes barcoding extensively. We use zebra printers and various barcode reading wands (usually USB connected) with wedges. Most of these wands allow you to set a postfix code to send after it sends the wanded data. I just set this to CRLF and that allows for easy wanding into webpages that are specially designed to accept this type of input. The Zebra printers use a language called ZPL. We created our basic label templates using ZPL and use PHP to fill out the template and send it on to the cups server (which handles sending the data to the Zebra printer).

[PHP] PHP5 binaries
It seems that none of the current major Linux distros provide PHP5 binary installation packages. By major I mean, RedHat, Fedora (it will be in F4 when released), Mandriva, Debian, Ubuntu, possibly others. Seriously, none have standard PHP5 packages, even optional ones. Does no-one use PHP5??? It's not exactly bleeding edge, having made a final release nearly a year ago. I'm trying to set up an automatable installation system for such evident rarities as RedHat Enterprise Linux 4, and I just can't find anything workable. Even php4 binaries are rare (especially ones with flexible options including things like pcntl). Perl is massively supported, with binaries for hundreds of extensions widely available. Why does PHP get such second-rate treatment? Is it particularly hard to build packages for? I'm quite used to building PHP5 from source, but it's not the most elegant way of deploying things. The PHP download page says Most Linux distributions come with PHP these days, so if you do not want to compile your own, go to your distribution's download site., but that's no use if no-one actually provides them for current releases. Even in the various rpm repositories PHP5 is a rare beast - for example rpmforge's members don't include it. rpmbone provides some very basic rpms, but they suffer from dependency problems (even when accessed via apt-get).

[PHP] Cache Problems
Ave, My whole Auto-Image verification application and has come to get stuck at the Cache in IE. It¹s working fine in Safari on Mac, but IE is picking up the image from the Cache no matter what. I¹ve tried the following: header(Expires: Mon, 26 Jul 1997 05:00:00 GMT); header(Last-Modified: . gmdate(D, d M Y H:i:s) . GMT); header(Cache-Control: no-store, no-cache, must-revalidate); header(Cache-Control: post-check=0, pre-check=0, false); header(Pragma: no-cache); Which I understood is to tell the browser not to load the page or it¹s images from the Cache.. But it still does. Nothing is working out. I don¹t know how to get that page to load fresh from the server and not IE¹s cache so it won¹t display the same Image over and over. Any suggestions?

return 'y';
elseif ($nm == 'xx')
return 'x';

}
$t = new Test();
print $t-y . \n;
print $t-xx . \n;
print $t-x . \n;

y
x

Not only can the user agent string be easly spoofed, but as a result of its abuse by certain webmasters(mostly Banks) Browsers such as Opera, and I believe Konqueror, have a setting that allows you to change the user agent string as a configuration option.

Re: [PHP] Can I prevent Server variables from being spoofed ?
Think about it. The server can only tell what the user agent is by what the user reports. For all you know it could just be a perl script or just a terminal session reporting as being Quicktime. So yes, a script kiddie could spoof the user agent. Heck, some browsers even allow you to specify the user agent you want to report.

Hmmm... couple of things:
Your if statement isn't checking the value of '$status'. It's checking if
the assignment *to* $status is true or false. At least I think so.
So, I think at a minimum you want:
if ( $db-query.
Also, what is $db-query supposed to return upon success? In the unix
world, programs typically return zero to indicate success and use other
values to differentiate b/n all the possible errors. if $db-query is
doing that, then that's the problem.
good luck.

How would we know? :-)
Of the 10,000 PHP Database Abstraction classes out there, you haven't told
us which one you are using.
So there is *NO* *WAY* to tell what the query() method returns, is there?
Actually, you don't even tell us which DATABASE you are using, so while I
say MySQL below, I mean whatever database you are using
When it *DOES* fail, why don't you log the error message MySQL provides?
error_log(@mysql_error());
Only, most likely, the database abstraction layer you haven't told us
about has some fancy method to get that information.
For some reason it is doing just the opposite. The data is added, but
it displays the error instead.
Then, most likely, the particular database abstraction layer you have
chosen doesn't work the same way as mysql_query(). So you have to adjust
your code to work with the API of that database abstraction layer, which
we can't possibly begin to tell you how to do, since we don't know what
database abstraction software you are using.
Am I misunderstanding something?
Definitely how to ask a good question :-)

Re: [PHP] Cache Problems
On Fri, May 20, 2005 12:11 pm, Rahul S. Johari said: My whole Auto-Image verification application and has come to get stuck at the Cache in IE. It¹s working fine in Safari on Mac, but IE is picking up the image from the Cache no matter what. I¹ve tried the following: Are you clearing out the cache after you add these headers? Cuz, like, if it gets IN the cache, the new headers you send don't count, cuz it never asks for them. header(Expires: Mon, 26 Jul 1997 05:00:00 GMT); Send something in the past, but not that far... It might decide to ignore you if you lie that much. header(Last-Modified: . gmdate(D, d M Y H:i:s) . GMT); header(Cache-Control: no-store, no-cache, must-revalidate); header(Cache-Control: post-check=0, pre-check=0, false); I think having too many of these is going to mess you up... header(Pragma: no-cache); Which I understood is to tell the browser not to load the page or it¹s images from the Cache.. But it still does. Nothing is working out. I don¹t know how to get that page to load fresh from the server and not IE¹s cache so it won¹t display the same Image over and over. If you really want to guaranteee no cahing in all browsers for all time, the random URL is the way to go. It's a shame that browsers will ignore the caching headers, but since they do, I don't feel guilty making them suck down more images then they should. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] ftp_fput() limit is 10 characters

Re: [PHP] Image Verification - Problems in Safari, Mac OS X
On Thu, May 19, 2005 6:05 am, Rahul S. Johari said: I did actually remove the Header which declared it as a Image/PNG and everything seemed to work in both the browsers. Great. Now it works in 2 browsers, and breaks in 237. You MUST separate the two. Period. Here's my situation though... I can't separate out these two files because when a user is on the verification page, where the Image exists, in case he reloads or refreshes the page, a new image should be generated and displayed, so that the verification code is different each time you reach the verification page. If I was to keep the image code in a different page, the verification page will pick up the same PNG image and display the same security code over and over without changing it. So you need some kind of secret token buried in the HTML which you can decode in the image and in their submit to see if they actually used human eyeballs to see the image. There are dozens of scripts out there that do this -- Perhaps you should review them to see how they work. The simplest solution I know of is to make up a random string and store it in an SQL table with the word in the image. http://php.net/uniquid http://php.net/md5 etc. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] update blues
Hi: I have a partially finished app using PHP and MySQL that runs on Mac G4 running System 10.3.9. Undoubtedly, I upgraded too many things all at the same time. Something broke. PHP and MySQL are both running. I can use the latest phpMyADMIN and everything is there in the database, so that should check both PHP and MySQL. Here are the changes in hardware and software: New Old Mac G5 G4 System Tiger (10.4)10.3.9 PHP 4.3.10 4.3.4 MySQL 4.1.11 4.0.17 myAdmin 2.6.2 2.5.4 When I run the app, I get the login page with no difficulty, but that takes me back to the page member.php which attempts to start a session and then from there to check the validity of the login by comparing the login variables to those stored in the database. The attempt to use session_start(); now gets me the the following two warnings: Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /Library/WebServer/Documents/testit/Logsafe_project/db_fns.php:212) in /Library/WebServer/Documents/testit/Logsafe_project/member.php on line 14 Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /Library/WebServer/Documents/testit/Logsafe_project/db_fns.php:212) in /Library/WebServer/Documents/testit/Logsafe_project/member.php on line 14 No cookie is created, so it is not obvious why it is complaining. I suspect something in the apache script for starting php. Can anyone suggest a good place to look? Jim -- Jim Feldman 14 Linda Lane Newton, MA 02461 617-527-0509
