Easy enough =) You're not running the mysql query =) You're never sending
a command to MySQL to tell it to execute the $sql statement

if( $booktitle AND "quantity" ){

$sql = "UPDATE Book2 SET stock ='$stock-quantity' WHERE
booktitle='$booktitle' AND quantity=quantity";
mysql_query($sql);
}

Should do the trick. Or even cleaner

if( $booktitle AND "quantity" ){
mysql_query("UPDATE Book2 SET stock ='$stock-quantity' WHERE
booktitle='$booktitle' AND quantity=quantity");
}

Sincerely,

Craig Vincent

Missed a spot =)

> if( $booktitle AND "quantity" ){

I'm not certain if this if statement is accurate. I've never used a
statement like this but from the looks of it the AND "quantity" part would
always be true (assuming it parses it). This could be adding to your
problem as well. I think you were aiming for something like

if ($booktitle AND $quantity) {

or how I do it (although it looks a bit messier)

if (($booktitle) && ($quantity)) {

Sincerely,

Craig Vincent

Subject: [PHP] Done w/ PHP - VB or C# ?

I know I'll get mauled big-time on this mailing list but I'm thinking
about putting PHP on hold for a while and learning ASP.NET

I love PHP and open-source computing but if one wants to get a job in
web development, you'll have a much better time find a job with both PHP
and ASP (among others) skills.

I'm going to hop on the ASP bandwagon but I'm not sure if I should
first learn ASP w/ VB or w/ C#

Any thoughts on this? What are the pros and cons of both?

Thanks!

As much as I'm not a fan of ASP (2 or 2.5, not worked with 3 much),
I'd have to say that you could definitely at least read a directory's
contents without having to purchase external libraries. Please don't
go overboard.

Wouldn't it be cool if you didn't have to be a C programmer to
write PHP extensions that you could distribute to others (whether
for profit or not)? I certainly think so, but it's currently not
possible right now. All those "nasty little companies" you mention
are making some money because they can program VB, wrap up stuff
as DLLs, and sell them. They see a need in the ASP community and
address it, while being able to make some money too. What a novel
concept!

It's all perspective. I'm not saying everyone who does PHP is a loser,
but I have met more than a few losers who happen to work in PHP. Same
with every other language.

Where the heck did you read that? Do you know what .NET is?
Glad that you do, because most other people don't - there really
isn't a good definition, so it's hard to say someone 'pulled everything
in'. What MS has done is retarget the 'hailstorm' service to
corporate intranets looking to do internal authentication as opposed
to a public authentication system. Hardly retracting .NET from
the scene.

There's a lot of interesting concepts in the .NET codebase out there now
(ASP.NET webforms, for example) as well as other platforms
(Java springs to mind). Just because it's "not PHP" shouldn't mean
you ignore it or worse yet, publicly denigrate it.

It's been a while, but I remember that it was impossible to create a
functional directory browser with off-the-shelf ASP functionality. The
file component was categorically unwilling to follow mounted shares until
we got some extra add-in. This was after a month of debate in newsgroup
microsoft.public.this.that.the-other-thing, and plenty of experimentation
during which I discovered, reported, and was contacted by MS engineers
about more bugs than I've ever encountered in PHP.

I don't think it's a bad thing that they see a niche and try to fill it. I
think it's a bad thing from the web developer's perspective that there are
so many unfilled niches.

Furthermore, in contrast to the PHP/Open Source world I find the
profiteering got annoying after a while. It was a drag just having to fill
out a P.O. every week to buy another ridiculous little thing that may or
may not be production-quality and had a no-refund policy.

And the fact is, most of those little companies provide wretched
documentation and support, and there is no real onlne user community in
the Windows world to exchange information with. Well, there are lots of
users, but the ratio of crap-to-usefulness in the fora is so high that
finding information is painful at best.

No doubt. But a development environment that's the centerpiece of every
late-night-TV-commercial "Are you tired of your Burger Hut job? We'll
teach you to be a computer programmer earning $70k/year in only 3
weeks!!!" tech school is bound to have a higher percentage of losers than
others.

Public denigration of what I don't understand is how I strike out at a
callous world that's denied me my just deserts: fame, millions, and a
torrid love affair with Nancy Reagan. Either address the fundamental
injustice here or cut me some slack.

This isn't specifically ASP, but NT permissions in general. PHP running under "off the shelf" Windows can't access shares either.

Honestly, I find that now in the PHP community as well, to a larger extent than I used to, but perhaps it's because I/we aren't in the 'sessions v cookies' mentality anymore.

Compiling GD support, for one, is a pain in the ass which you can't get really get good support for, due to the variety of systems. Servlet support as well. Java support has gotten better, but it generally just magically happens. I don't think I've had too many deep technical issues that have been resolved with help from the PHP community. Not because they're 'lesser' people, but we're trying to do stuff that most people don't do. It'd be like trying to get JScript support at an ASP site. Yeah, JScript works with ASP, but no one really uses it much, compared to VBScript.

Not sure how old you are or when you had this thing for Nancy - never been 'fanciable' since I've known her (but maybe I'm too much of a youngster).

For me personally I find working with ASP & .NET to be a pain in the butt, yeah sure you can to use all the fancy GUI's that can take care of some code for you etc.. but then there's the argument about php and having to write the code your self. Personally I find that a better approach as for me it's all about learning and achieving because at the end of the day you can sit back and look at it and go wow I did that from scratch from line 1 of code etc.

Basically it all comes down to personal preference. I'm coming from a back ground which doesn't include much programming at all (which can be seen by some of the dumb q's i've posted in here...) and I guess that using something with a prodominately (think that's how it's spelt) gui workings and that takes care of alot of code for me should be more appealing but it's not .... any way basically YOU have to decide what's best for you and that your happy with the choices that you've made as in the end it's you that's got to live with them.

& that's my 2 cents

All,

How would you implement 4 drop down lists....

Data in list 2 dependant on list 1, list 3 dependant on list 2 and list 4 dependant on list 3? Using an ODBC source.

attached mail follows:

You may wanna search the archives for this, as its been discussed quite a few times before.

Basically it comes down to either using some sort of client scripting language (Javascript, VB script etc...), or refreshing the page everytime someone makes a choice in the list box and then populating the rest. IE

They select Ohio in the first box, then you would refresh the page, and select * from cities where state = "OH"...

Now, when I use snmpwalk or whatever other function from within apache, it works (almost) correctly: snmp_set_quick_print causes php to return both the OID and the value although the manual says different, but I can live with that. the problem is that a simple script run from the standalone interpreter on the same machine behaves very strange. Example:

#!/usr/local/bin/php -q <? snmp_set_quick_print(1); $test=snmpwalk("1.2.3.4","public","system"); for (reset($test); $i = key($test); next($i)){ echo "$test[$i]\n"; }

does not print ANYTHING (nothing in php.log, also. I have error_reporting = E_ALL in php.ini) but if I do a snmpget("1.2.3.4","public","system.sysName.0") I get system.sysName.0 sysName not set which is (almost) correct. the snmp* commands from the ucd-snmp package work just fine. Does anyone have some clue on what could have happened? Thank you.

Dear All,

Firstly, I am a newbie to php so please be gentle.

I'm having problems with carriage returns placed in a file on a Linux based server. When this file is download to a WindowsXP machine the carriage returns are quite frankly useless. I just get "[]" (where "[]" represents an undisplayable character. No actual carriage returns or newlines!

I generate the file using the following code (fragment only):

while($row=mysql_fetch_array($mysql_result)) { $f_title=$row["title"]; $f_first_name=$row["first_name"]; $f_surname=$row["surname"]; $f_email=$row["email"]; fputs($file_op,"$f_title, $f_first_name, $f_surname, $f_email\n"); }

I then use the following link to a download_it.php script as described in Tansley as follows:

$parameters="file_name=".urlencode($file_name)."&file_size=$file_size"; echo "<A HREF=\"downloadit.php?$parameters\">download it</A>";

The download_it.php file looks as follows: <?php #downloadit.php $file_name=urldecode($file_name); header("Content-type: Application/octet-stream"); header("Content-Disposition: attachment;filename=download/download.txt"); header("Content-Description: PHP Download"); header("Content-Length: $file_size"); readfile($file_name); ?>

Appart from the fact that the Content-Disposition appears not to be working under IE6 since the file name is not correct.

The downloaded file does not contain Windows type carriage returns of newlines! However it does contains the data thank goodness.

What is the fix?

Unix type machines separate lines with a newline char "\n" Windows type machines separate lines with a return and newline "\r\n"

If you want things to look nice on both, use "\r\n"

"When I test it fails" is not a useful problem report.

Show the relevant parts of the code you're running and tell us what, specifically is happening (i.e., if an error message is displayed, paste that into your problem report; if a variable seems to be getting an unexpected value, change your code to print that value out, and then show us both the code and the value that it actually printed out).

Otherwise it's just sort of a guessing game.

Did you restart your HTTP server? If not the php.ini file was not read. Also, if you are using Apache there is a timeout in that server that must be changed as well. Same for IIS. Anytime any changes are made to any files which affects the web server requires that the web server be restarted.

Not sure I get your question. Cannot be "run" or "executed" by whom? By the web server? Just don't let it run them. By people who download them? Impossible. There are too many executable formats. The only choice would be to have a whitelist of file formats (i.e., "GIF", "JPEG", "PNG", use 'file' to check the prologue of each file, and then toss anything else.

Two related questions:

1) Is there any work being done to support the retrieval of the LDAP schema in PHP (similar to Perl's Net::LDAP::Schema)? Is there any other good way to get this information into PHP?

2) Is there any way to change the search scope of an LDAP search in PHP? Specifically, the following OpenLDAP search command will fetch the schema from the server: ldapsearch -s base -x -b 'cn=subschema' objectclass=* + But, I can find no way to switch the search scope from SUB to BASE, so the equivalent call in PHP won't work.

Any suggestions?

Hey guys I recently join this list and this is my first real post to it so if I f**k something up please do beat me to death. :)

I have a simple mailer script that was mailing POSTed form information to a client, this script was running on a Debian box w/Apache. This server is having hardware issues so I moved the sites to a win2k machine. The same script bombs out when it trys to use the mail() function.

The error message I receive is not so enlightening:

Warning: Server Error in D:\Inetpub\belcoind.com\mailFunc.php on line 24

I changed the line in the php.ini to read:

SMTP = localhost;

the server has its own smtp service running on it

I also tried:

SMTP = mail.mydomain.com;

This genereated the same problem.

I have been using PHP with Apache forever but I rarely use it on Windows so any insight into this problem would be great.

Hi,

I am doing some validation on files that are being upload. I only wish to allow users to upload files that are in *plain text* format (not neccessarily with a .txt extension). I have the following piece of code, which works fine in IE, but in Netscape Navigator:

if ($file_type != "text/plain") ... error handling...

Can anyone explain the reason for this, or offer a better solution?

The uploaded mime type is set by the browser, not by PHP. So I guess in your Netscape case it isn't sending the right type.

Perhaps have a look at the 'file' UNIX-level command and use that.

My question will probably expose my woeful lack understanding of security breaches, but perhaps someone can enlighten me.

On my site, registered members will be allowed to upload jpg/jpeg pictures. I'm concerned about possible security problems. First, is there a way to ensure that a picture (and not some other malicious stuff) has been uploaded?

Aside from checking the mime type info associated with the file, is there any way of verifying what's in the file that has been uploaded? (I'm using Linux LM8.2) Would it be possible to fake info to fool this check? Would verification checks for html/scripts/commands be of any use?

Secondly, since the file in question is already uploaded and saved to disk in /tmp or wherever, wouldn't any verification scheme be sort of, 'after-the-fact'?

I would appreciate any input, suggestions, or ideas on what to do here. Am I being overly-paranoid about this, or do I have legitimate security concern.

Are you afraid of someone embedding PHP in a .jpg file? That's not really an issue as your web server is probably configured to only serve up PHP as .php files. Likewise, your web server config is likely such that any .jpg file is served up as content-type image/jpeg and as such it really doesn't matter what sort of junk is embedded in the image. At most it will show up as a broken image icon in your browser.

right.

the thing you may need to worry about, if you provide some sort of service that allows for anyone to upload a jpeg file that anyone else can then download, is people using programs that piggyback other data (mp3 files, rar archives, etc) on those images.

one simple check you can do to minimize this is to compare the image dimensions to the file size -- if you've got a 120x120 image in a three meg jpeg file, something is probably awry. so with a combination of php's getimagesize() and filesize(), you can try to detect that sort of thing.

(this is one of the problems that plague sites that provide free webspace. it's only a security issue insofar as this can constitute an effective denial-of-service 'attack' on your systems.)

I thought there had to be function out there that could examine the actual contents.

Now the question remains, would an ereg/eregi check for html/code/commands work on a "jpg/jpeg" type file? From a brief examination of one, I note that it's not text, but code. I tried writing some text commands into a jpeg file to see what would happen, and wasn't too surprised that the file didn't load -- but then again, I don't know what I'm doing:>

I suppose, following what I saw in a movie "Along Came a Spider" -- manipulating image files with hidden text files, etc. -- sort of put me on guard. I have no idea whether this is even possible. . . sounds probable though. Would be great to find out before the site is compromised.

I thought that I maight have set some file access uncerrectly and Java servlets cannot read them so I tried to display simple file: <?php echo "Hello World<p>"; ?> I got the same result as previously.

I can display any of those files when I load html file: <html> </head> <body bgcolor="#A8FFFF" text="#0000A0" link="#408080" vlink="#0000A0" alink="#008040"> <h4>SMT MONITORING-----------</h4>

So I am really confused. I just suppose that the problem is somehow related to html being generated on-fly in Java servlets. But I don't understand why is that.

The source of Java generated html page is: <html> <body bgcolor="#A8FFFF" text="#0000A0" link="#408080" vlink="#0000A0" alink="#008040"> <h4>SMT MONITORING</h4>

How is possible to keep this info to a MySQL database with PHP? I think is not possible becouse PHP runs first. Also how is possible to get with PHP info like this (browser type ecc) and user's IP address without Javascript? Or use Javascript and then run a php script to write it to the MySQL database?

Thanks

Hi All

I am trying to write something similar to a server console display, is it a good idea to use PHP?

Wondering how things like 1. server clock (similar to a clock applet) 2. server status can be displayed with PHP code?

Note: I need to display the above two in a continuous fashion on the status bar!!

Many Thanks Dominic

attached mail follows:

PHP and Web Servers probably make a bad choice for what is essentially a real time application. PHP and web servers expect to serve up a page of essentially HTML(and Javascript, or Java Applets), then close the connection to a browser so that it can handle the requests of others, and not deal with that connection again until the browser makes another connection, usually as a result of a hotlink click, or submit.

There is a way to simulate what you want using JavaScript (if PHP can output HTML, it can also output Javascript). Check http://www.hotscripts.com in their JavaScript section for routines to perform 3 functions,

1. a routine which will cause the a page to request a refresh every 10 seconds or so, there by requesting the same page, which your PHP can fill with the latest (real-time?) data. 2. a routine for using JavaScript to display data on the status line. 3. a routine for displaying the time (using the clock on the browser machine).

hope this helps,

Any suggestion will be greatly appreciated. Thank you in advance

As fas as I know, the only way to do this is to give somebody instructions to right click on the file and so "Save As".

Plan B is to put the GIF in a ZIP file and let it be downloaded like that.

If there were actually an image I'd use:

wget http://domain.com/image.gif

$imageData = implode( '', file( 'http://domain.com/image.gif' ) ); $length = strlen( $imageData );

if( $length > 0 ) { if( (fh = fopen( 'destination', 'w' )) ) { fwrite( fh, $imageData ); } }

Not sure how to resolve this, looked at php.net for the headers available and this is the error I am recieving:

Warning: Cannot add header information - headers already sent by (output started at /path/to/connection/script/db.php:6) in /path/to/login/checking file/auth_done.php on line 13

Here is the code that is in auth_done.php:

session_start(); require '/path/to/login/checking file/db.php'; $db_table = 'auth_users'; $sql = "SELECT * from $db_table WHERE un = \"$u_name\" AND pw = password(\"$p_word\")"; $result = mysql_query($sql,$dbh) or die("Couldn't execute query"); $num = mysql_numrows($result); if ($num !=0) { session_register('u_name'); session_register('p_word'); $msg_success = "Good freakin job poindexter!!"; } else { header ("Location: index.php"); // This is line 13 that is my error generator }

This is the code for the db.php script: <?php $dbh = mysql_connect('localhost','username','password') or die('Could not connect to database, please try again later'); mysql_select_db('db_name') or die('Could not select database, please try again later'); ?>

Any help would be great! I am assuming there is another way to redirect users besides the header function, just not sure what it is or how to use it. Thanks in advance, Jas

Hi Jas,

I normally output can output a JaveScript document.location.href="XXX.XXX"; command

Plan B is to do your processing before there is any output and then decide whether or not to do a redirect using the header() function.

Don't feel bad about this. This is something that messes a lot of people up. The browser knows where your headers end and where content begins by adding blank line between the headers and the rest of the page. ALL headers must come before any content is printed to the page. PHP will give you that error if you attempt to write a new header. So in fact your problem is not on Line 13.. but is actually on Line 11. There are at least two ways to avoid this...

1. Don't print content before headers. :) 2. Use output buffering to write the whole page before it is outputed to the browser.

one REALLY notable advantage is:

if you us ob_*() functions, instead of writing HTML pages with php tags inserted, you can write XML pages with PHP tags inserted. then after you're done, you can pass the contents of the output buffer to an XSLT processer like sablotron, THEN outputting an HTML page.

Pros:

- headers can be added at any time - buffer content can be post processed (gz compression) (xslt) - if an error occurs can avoid serving half a document

Cons:

- transmission of content doesn't start until preprocessor completes - slightly more overhead since content must be stored in memory until buffer is flushed.

Hurmph. Well, the upgrade to 4.2.x did it for me under 98. I just need to check the rest of my code, though. For now, seems pretty harmless. Thanks, though.

As you can see it contains "--with-gettext" so I'd expect a function like bindtextdomain() is availible. However, Horde (chora, actually) reports: Fatal error: Call to undefined function: bindtextdomain() in /home/virtual/site4/fst/var/www/html/horde/lib/Lang.php on line 91

What could have gone wrong and how can I fix it?

Thanks in advance

I have some ideas on how this should be done, but I'm at work and can't really test them, so I was thinking maybe I could run it by you all and maybe get some feedback and/or new ideas.

I have a PHP/MySQL-generated page that displays image thumbnails. Currently, I have a loop that makes a table and table rows, fills the rows with the thumbnails, then when there's no more information, it completes whatever row it's on with blank <td>'s, then closes the table.

This was working fine, but my site is actually attracting more traffic than I originally thought, and I'm getting more image submissions. It's getting to where it's no longer practical to arrange all the thumbnails onto one page, I need to have like 25 on one page, then have the script create a link at the bottom so users can click and see the next 25.

I'm thinking I need to use some kind of row count language in the script, i.e. first count how many rows are in the MySQL table, if it's less than 25, just display them all. If there's more than 25, display only 1 - 25, then create a link to view 26 - 50, etc.

Is that what I need to be looking into? Any other ideas would be appreciated. Thanks!

$query = "SELECT * FROM mytable LIMIT $i, 20";

Where 20 is the number of rows to retrieve and $i is the starting row.

By incrementing $i + 20 you can do next, prev buttons, or parse the total number of rows into page links (prev - 1, 2, 3, 4, 5, 6.. 10.. 20 - next).

Search www.mysql.com for more information about using LIMIT in your queries.

Great! I think that's the SQL function I needed.

Now for the PHP part - I'm a bit fo a newbie at writing code, so bear with me here. My query string is currently something like:

$sql = mysql_query("SELECT * FROM mytable WHERE color=$color");

So I would modify that to read:

$sql = mysql_query("SELECT * FROM mytable WHERE color=$color LIMIT $i, 25");

Where $i = 1 To get just the first 25 records. I think I'm confused on how to set $i and create links. Would I just initially set $i = "1"; then make links that point to:

myscript.php?color=red&i=25

Then have a $_GET['i'] variable in my script and set $i equal to that?

Your help is appreciated. Thanks again.

One way to get it started would be to work strictly within the links. Don't initilize $i unless it is not set (which logically would mean your visitng the page for the first time). So..

if (!isset($_GET['i'])) $i = 0; else $i += 20;

Another way would be to extract the number of total rows, divide by 20, and build a list of links in a for() loop. $num_rows = mysql_num_rows($sql); $num_pages = floor($num_rows/20); for ($i=0; $i<num_pages; $i++) { // create links with $i in the url string. }

There are many other ways of doing it but this should get you started. Good luck.

Do a google search for ADODB. It's a PHP database abstraction layer. It has built in 'pagination' methods (Previous X, next X) along with an example of how to use them.

You should also add an ORDER BY clause in there, as the SQL standard doesn't guarantee the order that rows are retrieved in. There's a chance that you'll get, say, 20 rows on the first page, go to the second page and get some of the rows you've already seen on the first page. If you use an ORDER BY, you'll at least guarantee that you'll get them in the same order each time.
