Hi Everyone,

I'm trying to get a very simple "sum" of the values in an MySQL database
field column. I have very little experience with PHP and SQL, but I learn
quickly. :) Our resident PHP expert who built the full script is really
busy, so I've been trying to do this myself. The farthest I could get from
just reading various posts in other forums was:

$SelectQuery = new Query ("SELECT SUM(GiftSubscriptions) AS GiftSubs FROM
Registration");
$Result = mysql_query($SelectQuery);
$Value = mysql_fetch_array($Result);
echo $Value['GiftSubs'];

However, I'm getting this error:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result
resource

Can someone tell me what's wrong with this part of the code?

Thanks,
Kurosh

You're query is failing. Use mysql_error() to find out why (probably
because you need a GROUP BY clause).

Hi Hugh,

Thanks, so far so good... no error messages. What next to get it to display
the total properly?

BTW, I changed "$SelectQuery" to "$TestSub" since "$SelectQuery" is used
repeatedly in this script, and I figured it might conflict if I didn't use
the "new Query" part.

"... but I delete all the content by this" Why?

In del.php you would read in the file using file() then write out any lines
not beginning with $id. So something like:

$news=file("this.txt");
$fp = fopen('outputfile', 'w');
foreach ($news as $line) {
  if (strpos($line, $_GET['id']) !== 0) {
    fwrite($fp, $line);
  }
}
fclose($fp);

I have been mostly using function in my php code, and lately I have been
curious about classes. I have a vague idea of classes from my C++ class
that I took a few years back. Can someone please explain to me when is a
class useful over a set of functions? I have seen very few code with
classes, so pretty much always stayed away from it.

Thanks,

Almost always. Object oriented programming offers many many advantages
(that I cannot get into depth on here). There are a few exceptions
where you would not use classes, such as utility functions like max()
and min() that would be used generically.

The most basic purpose of a class is to define your own 'type' of
object. When you create a class you are encapsulating an 'idea' into a
set of attributes and behaviors specific to that type.

Designing classes not only offers a great way of organizing code but
inevitably forces you to think thoroughly about the logical separation
of code and to refine more and more towards an idealized type with well
defined and sensible behavior. Conversely non-object oriented
programming tends to lack in clarity and intended usage, making it
difficult and confusing to use, getting exponentially worse for complex
problems.

Classes have methods (functions) that are designed to work specifically
on members of that class or perform operations directly related to it.
Plain functions, however, have a tendency to be vague and complicated
by argument lists. Furthermore they are easier to be misused and can be
prone to latent errors.

In the end, it's like driving a car: the engine is neatly hidden under
the hood and you don't care or want to know about the internal workings
of it. You just want to get in, turn the key and drive. Classes are no
different... they provide a simplified user-friendly interface to
complex things. It's luxury in programming :)

I would suggest getting some books to learn further, and just start
using classes.

Tim,

This is really beyond the scope of this list, but I can help then it
doesn't matter. :-)

A few months ago I was asking myself the same questions you are asking
now. I found the following articles:

http://www.sitepoint.com/article/913

http://www.sitepoint.com/article/677

http://www.sitepoint.com/article/693

http://www.sitepoint.com/article/909

There is some valuable info on this site, you might want to look through
the rest of the articles under Sell Your Services, category:

http://www.sitepoint.com/cat/85

And if you want a book on the subject, take a look at:

Hi,

I have two very simple php scripts and the second srcipt is not seeing the
variables session_registered by the first script.
I'm running the latest version of php. And have both "register_globals" and
"track_vars" set to "ON".

Well, the first script prints out the session var fine, but not the second
one. What is wrong? Is there something else I overlooked? Thanks for your
help!

1st script - page1.php:

session_start();
session_register("sess_var");

$sess_var = "Hello world!";

echo "The content of \$sess_var is $sess_var<br>";

?>
<a href = "page2.php">Next page</a>

2nd script - page2.php:

session_start();

echo "The content of \$sess_var is $sess_var<br>";

session_unregister("sess_var");
?>

It's best to state the specific version of PHP you're using rather than just
'latest' (as it could mean different things to different people at different
times).

If you're using PHP > 4.1.0 then you ought to be using $_SESSION for all your
session needs -- see manual for examples.

I have the following scenario:

I have this timeclock program that my employees access by logging into and
the program pretty much allows them to clock-in and clock-out. The problem
is that I noticed some of the employees were clocking-in and clocking-out
from their home. The main problem is that the machine at work that the
employees use to access this program does not have a static ip address. Is
there any way to access the mac address in php.

Any ideas?

Hi all,

As you will guess from this question I'm new to all this. Firstly I hope
this is the right list.
I have installed the latest version of Apache, and the latest version of
PHP, on Windows 2000. I can start the server fine but as soon as I change
the httpd.conf file and add the LoadModule section the server refuses to
start.

I wonder if anyone can shed any light on this. I can run PHP under IIS 5.0
which I have installed and tried, but would prefer to use Apache. IIS has
been fully removed from the machine before the installation of Apache.

Hope someone can help.

King Regards

Tim

do you have an exact error message?

so far i can only point you to some often made mistakes:

- did you copy php4ts.dll to c:\winnt\system32
- did you copy php.ini.dist to c:\winnt, renamed it to php.ini and modified
it?

- in httpd.conf added these two lines?

hi everyone,
i want to know what the good software for PHP Editor Programing, like Visual Age For Java, or Visual .NET from Microsoft...

attached mail follows:

The "editor" topic has been beat to death, please check the archive.

However, PHP is code, all code, there's no "visual" component. All a visual
editor would give you is a prettier interface; be more concerned about an
editor that lets YOU write quickly and efficiently, whether it be vim,
emacs, UltraEdit, EditPlus, Jedit, Notepad, Pico, Joe or something fancier
like HTMLKit or BlueFish. (PHPEdit seems to be reported as still buggy.)

You can't do it that way. If a web page is missing, the webserver will
transmit the error page for code 404. You cannot rely that this will always
the string you're looking for, and you cannot be sure that a regular page a
link points to will _not_ contain this string.

Just to omit the warning, you may use the silent-error notation
fopen($url, 'r');
but this will always work unless the host portion of the URL cannot be
resolved.

You need to employ a method where you receive the MIME headers additional
to the page body. Have a look at cURL
(http://www.php.net/manual/en/ref.curl.php) how to do this.

Another alternative is to look into the track_errors INI directive which
will populate the $php_errormsg variable with the last error that
occurred... in that case something like the following could be done:

        $fr = fopen("http://www.coggeshall.org/myfile.php",'r');
        if(!$fr) {
                echo "The error that occurred was $php_errormsg";
                // Do test on the error message here
        }

Although that won't be absolutely full-proof (since there is no absolute
which says that the error message "failed to open stream: HTTP request
failed! HTTP/1.0 404 Not Found" is going to be identical in new PHP
versions) it is an option to consider.

Justin, I took your suggestion and tried out the above on some test files. I
made some slight mods, but, it works perfectly. The only thing I don't like
about this solution is that the session ID is appended to the end of the URL
for everyone, even if they have cookies enabled. (I have trans-sid enabled).
Is there any reliable way to avoid this, or is this just a small side-effect
of making the site accessible to all?

Thanks!

Monty

attached mail follows:

Hmmmm,

Theory only here:

If there is a GET value of PHPSESSID (or whatever your sessions are named),
then the user is more than likely taking advantage of trans-sid (sid's in
the URLs), and cookies are not available.

So, we only want to append the sid to URLs in a redirect IF the sid is found
in the URL already. If there is no SID in the URL, then perhaps we can
assume it doesn't need to be this time????

<?
// UNTESTED
function redirectWithSession($location)
    {
    $sid = session_id();
    $sname = session_name();
    if($_GET[$sname])
        {
        header("Location: {$location}?{$sname}={$sid}");
        }
    else
        {
        header("Location: {$location}");
        }
    }
?>

Again, please test thoroughly, because I haven't thought through the
instances where this might break something really... maybe there aren't
any!!

Guys, that's exactly what the SID predefined constant is for -- it's defined
only when a session is active, and it has the value
<sessionname>=<sessionid> (e.g. PHPSESSID=1afd764ecb938274) if and only if
the session id was passed in the URL -- otherwise it contains the empty
string. So you can safely do:

header("Location: {$location}?".SID);

and get the desired result.

Good point... except I had some problems with SID a while back... must do
some re-testing... can't remember much about it now.

[snip]
Can I trust every
browser to check for old cookies on startup and eliminate them? And still,
even if I can, wouldn't the cookie be intact to read on the harddrive
until
the browser is started again? I was thinking about slicing the username
and
password strings in two, and storing the halves in cookies and server
sessions respectively, e.g.:

Username = Admin -> Cookieusername = Ad, Sessionusername = min
Password = Secret -> Cookiepassword = Sec, Sessionpassword = ret
[/snip]

Never trust any program that is not running on your system. How do you
know that your user is actually running a browser and not some self
written program? So the most important lesson is never to trust anything
that is not under your control....
You should never store the password in the cookie. Better is to send some
sort of id as the cookie and use that id to retrieve some sort of database
record for password comparison. That way the password user combination is
always under your control.
If you depend on tight security your best bet is to authenticate the user
eachtime he reenters your page and not use cookies for authentication at
all. This can be a pain but is by far the safest. Even better of course
would be some certificate authentication. This could be very bothersome to
program though.
If you must save the password as a cookie ( I DO NOT RECOMMEND THIS AT
ALL) at least encrypt it with a hash function like crypt using a different
salt for each user. Then compare the hash value to a stored
passwordhashvalue on your server.

loop, it works fine. Is this a problem with foreach?

If it is, i'll stick to while, but with a counter to generate a key.

I need to access the row by colum name...

eg:

$row['id'] $row['title'] $row['detail']

My table gen script puts the relelvant fields into the right boxes, and my
maths works from the $key to put <tr>s in the right place.

So i need a loop that will loop as many times as there are rows, so while
works fine, but i also need a key, so that is why i wanted to use
foreach(mysql_fetch_array($result) as $key => $value) but my problem arises
when i try and access $value in the foreach loop, it is not an array of the
row, but all the values in the row imploded together.

And doesn't this solve your problem? While loop will loop for each row,
foreach will give you the key and value. How else do you want to loop?

while($row=mysql_fetch_array($result)) {
        foreach($row as $key => $article){
                //here you have $key and $article
        }

I've decided to drop foreach altogether now and just used good old while on
its own with a counter to use as the key. The second foreach in your example
would run on each column on the row, when i need to just be able to access
the columns.

I appreciate the help though, thanks ;o)

Am now using:

$key = 0;
while ($row = mysql_fetch_array($result)){
//stuff accessing $row['id'], $row['blah'] etc...
$key++;
}

Hi,

I am creating a timesheet application, how can I make sure that a user has
entered a number, and that the number is a whole number or a decimal up to 2
places, and that the number is less than 24?

Thanks for your help

Try this... I don't know if this will suit your needs but it'll give you
an idea:

<?php

// $a contains the time entered by the user

         if($a > 0 && $a < 24) {

                $time = number_format($a, 2, '.', '');
                echo "Time: $time\n\n";
        } else {

                echo "Invaild Time.\n\n";
        }

Another way is to do it on client side (javascript)

I'd probably do this with a regex plus a quick test for in-range values -- something like (untested):

        if ($number>0 && $number<24
             && preg_match('^[0-9]{1-2}(\.[0-9]{1,2})?$', $number))
          do_stuff;

You could also tweak the regex to filter out out-of-range values and dispense with the range checks -- something like (again untested):

if (preg_match('^(1?[0-9]|2[0-4])(\.[0-9]{1,2})?$', $number))
do_stuff;

Cheers!

Dear all
Here is the situation :

Our automation system will generate a large number of pdf file to a specific
folder every day. The name format for all these pdf file is
"xxxx.20030602.pdf".
xxxx is the name of the file,
20030602 is last working date.

what i want to do is:
1. create a sub-folder inside this specific folder, and name it to current
month(Jun-2003)
2. move the pdf which is not containning last working's file name to this
new create sub-folder.
3. the files with last working date's name will stay on the specific folder.

question :

1. I had used a date function with "w" parameter to check if current date i
execute the script is monday (1), if so , i tell the script to take the
current date minus 3, so the date will become last friday (as our last
working day), then i can base on this date to tell the script which files
should not be move to sub-folder!

q: how i can do a date subtraction in php? (eg. "2003-06-02" - 3 =
"2003-05-30")

Hi,

One way would be to have two buttons in your form, but submit to only one
page:

... and then, on process.php, you decide what to do:

if ($_GET["op"] == "Continue") {
// do continuation stuff, or redirect somewhere
} elseif ($_GET["op"] == "Stop") {
// do stopping stuff, or redirect somewhere
} else {
