No. You could make them people pay a substantial sum of money for each vote
they place -- that'll make them think twice before putting in multiple votes
:)
But seriously, look in the archives the hows and whys have been covered quite
comprehensively in the past.

But if the page was all lowercase they wouldn't be hitting your 404.php page
in the first place? Or am I missing something?

It cannot continue after a die(), unless there's a bug in PHP. If you still
think that it does then post your full code and the circumstances under which
it happens.

Correct.
But if the page was all lowercase they wouldn't be hitting your 404.php page
in the first place? Or am I missing something?
They can still go to nonexistantpage.php.

Hmm, odd. When I try to duplicate it, I can't. Either this bug doesn't
always happen, or I made a really dumb mistake, or something...

Try specifying the full path to the python binary and possibly the full path
to ncMailer.py as well.

Good suggestion! I switched everything over to absolute paths, as I should

Does the webserver have permission to:

Thanks for all the help! I really appreciate it. :)
Hm, I'm actually not sure if my host allows that. This could definitely be
the problem. Is there a simple way to find out, other than asking? For now,
my guess is I can only execute the file from my cgi-bin directory.
Okay, we're a step closer to victory. I can run the script, via a web
browser, through my cgi-bin. Unfortunately, this kind of defeats to purpose!
This is no better than my original PHP script, since it too will hang the
browser on long operations. I'm back to square one, if I can't run that
script without the browser waiting on it to finish...
Any ideas, given this new situation?

For instance, is there a way for my PHP script to log into my shell account
and *then* send the command? Since I can execute the script, but PHP can't,
this would solve the problem -- if it's possible.

Just in case any of you are still watching this thread, I thought I should
post the exciting conclusion!
Not too exciting, actually. In the end, I've simply added my Python script
to crontab. It runs every 20 minutes, and if the mailing file has changed,
it sends out the e-mails.
Pretty simple, and actually what I was first advised. Pity I thought I could
find a better way. ;)
Thanks to everyone who helped me out! I learned a lot, so it was worth my
screw-ups.

Hi all,
It seems that there might be some basic solution on this that I never
received a memo on...
Basically, I'm looking for a way to avoid repeat posts. If someone, for
example, adds something to a bulletin board, clicks submit, and then presses
F5, they're just 1 click away from re-submitting the form and posting the
same information for a second time. Is there an easy way to avoid this?
I've thought about using a "unique visit id" or something which gets
triggered when a visitor posts, but that seems like a lot to do...
Also, do you think I should look into redirecting the user once they've
posted so they can't go back?
I just don't know where to begin...any input is greatly appreciated.
Thanks!

when "generating" the form, include a hidden field which has a unique,
random value.
then the script that recieves/validated the post should check that the value
doesn't already exist in the database before inserting... the only way
someone can double-post is by actually refreshing the form (thus getting a
new hidden field.

they can still go "back" after a redirect... it's just pages in the browser
cache...

I did searches on this one...I'm using NNTP so it's nice...unfortunatly, no
one had quite the same problem.
I had thought about the random value already (see paragraph about unique
visit id), but it just seems like so much to keep track of...
After asking on other board on the same topic, one theme seems to be the
same...just use redirects.
If anyone else is having the same issue, you can do a redirect using the PHP
header() function to send the user directly to the next page. If the user
goes back, they will get a new version of the form, and less browsers will
support resubmitting.
Also, on the same note, if anyone is using buttons as links, make sure you
are using an <input type=hidden onclick="window.location='http://whatever'">
command instead of submitting a form with no fields. This will solve the
problem here.

Actually, there is a different solution to this aswell. One that is used
by phpBB and XMB, and maybe some others aswell.
Basicly, it's an anti-flood system. It works like this:
- You are a member and logged in
You post, and the post gets inserted into the database, and with it,
also the time of posting is kept.
When you post the next thing, the script checks if there was a message
posted, by that user in the last X seconds (can be set manually). If so,
it will return a message saying not to repost stuff. Otherwise, it just
continues...
Hope this helps,

Why not create a unique constraint with the userid, day (without time) and post
content.
Is it going in a DB?

How about saving a timestamp when the user posts a message and when he posts
another message check whether the user already posted a message in the past,
let's say, minute. I saw this used in a lot of forums...

Index on text columns does not seem very efficient, IMHO.
If he wants to avoid multiple inserts, the random unique ID is enough.

Or to make it easy, here's the line you need:
$info = mysql_fetch_array( $result );
Put that line right after the query. So, here's sample:
$Link=mysql_pconnect($Host, $User, $Password);
$db=mysql_select_db($DBname, $Link);
$query=mysql_query("SELECT * from calendar", $Link);
$result = mysql_fetch_array( $query );
print $result[meeting];
You can also use Objects:
$result = mysql_fetch_object( $query );
print $result->meeting;
If you're getting more than one line, you need to fetch each row. For
example:
$query = mysql_query( "select * from capitals" );
while ( $a_row = mysql_fetch_array( $query ) )
{
print "$a_row[capital] is the capital of $a_row[country]<br>\n";
}
Hope this helps!

Dear Sirs,
I'm using PHP and MySQL to make my programs. But I think I discovered a bug
in PHP or in MySQL (I don't know!).
In one of my files I have the following:
MYSQL_CONNECT("localhost", "**user**", "**pass**");
mysql_select_db("be");
$r=MYSQL_QUERY("SELECT n,u,m,h FROM d WHERE id='$id'");
/* Some code including "mysql_num_rows" and "mysql_fetch_array($r,
MYSQL_NUM)"
And the another query:
*/
MYSQL_QUERY("UPDATE d SET h='$h' WHERE id='$id'");
/* i don't know why but this doesn't work! But if I close the connection and
open another te query is done:*/
MYSQL_CLOSE();
MYSQL_CONNECT("localhost", "**user**", "**pass**");
mysql_select_db("be");
MYSQL_QUERY("UPDATE d SET h='$h' WHERE id='$id'");
---------------
I don't know why is this? Because I'm used to do more than a query per
connection and this never happened!
I'm using Win 2k, Apache 2.0.43, MySQL 3.23.49-nt and PHP 4.3.
I hope you solve this,

You really should be using a $link variable...it's good habit:
$link = mysql_connect(...);
mysql_select_db( "mydb" , $link);
$query = mysql_query( "select..." , $link );
$result = mysql_fetch_array($query);

Personally I say get yourself a good simple dbconnect class and make life easy.
Also if you ever change users, database name etc, you onlu have one place to replace
it in your code.
I wrote mine based on http://www.vtwebwizard.com/tutorials/mysql/
Take a look at it. Nice and simple.

Hi,
I'm dealing with the following issue:
how to determine whether the current page request has been responded
normally, eg. output has been sent to the browser as regular, or just a
redirection header sent to it header('Location: '); ?
Some words about the background:
This functinality would be implemented in my error handler class which
does not depend on any application framework, or programming style, or
whatsoever. And it must be used within a callback function by nature of
error-handling.
So I'm seeking for a native PHP solution (mostly a function), but any
suggestions are welcome.

Might or might not be helpful.. but I had the same thing happend when I added
--with-jpeg-dir=/usr/lib
Everything looked fine... but I could not call imagejpeg. (PHP 4.3 - RH8 - apache2)
Once I did a make clean, ./configure -with-xxxx ... , make, make test (to see if it
had jpg), make install
It worked. It really needed to have that make clean done first. Don't know if this
will help you or not.

Hi,
I'm trying to write a function that validates the input in a textarea. I
just want to allow alphanumrical characters, and if the user enters
anything else, I display an error message by calling error().
But the following doesn't work. Even if I enter "hello" in the textarea,
I get the error message. What am I missing?
// validate entered text in textarea
function validate_textarea($unchecked_text) {
if (!preg_match ("/^[a-zåäö0-9]$/is", $unchecked_text)) {
error("You have used unlegal characters, just alphanumeric is ok.");
}
}
Best regards,
Anders

You need to tell preg_match that there will be multiple characters. Right
now, you're searching for one, and only one.
if (! preg_match ('/^[a-z0-9]+$/', $unchecked_text)) {
The "+" means one or more matches to the range in brackets.
-- tracy

I've seen both guest books and user forums "hacked" by users who enter
javascript or other code, and that way redirects vistors to other sites or
do other unwelcome things. What expressions should I look for and not allow
in my forms?

I've been using Apache, MySQL and PHP under Win2k for a while to learn
PHP. At the moment, I'm running PHP 4.2.2, MySQL 3.23.39 and Apache 2.0.40.
During the holidays, I've read about a security hole in MySQL and
therefore plans to upgrade to 3.23.54a. At the same time, I want to install
PHP 4.3.0 and Apache 2.0.43.
But when I started to look for upgrading instructions for each software
package, I find nothing.
Therefore, I would like to know how to perform an upgrade of each package?
Should the MySQL and Apache deamons be stopped first?
Should I install into my current directories?
Will my config files be overwritten?
Does it matter which of the three I upgrade first?
What more should I keep in mind?
If questions like these are considered off topic, please let me know.
Best regards,
Anders
