Dear friends.

I have a site where I have news headers. I wish to count the clicks on the
news headers so that I can see how many times each of the the news has been
viewed. This way I can show the "most viewed" news.

Can one of you please advise hwo this can be done?

Thanks
Denis

I think the best way to do this would be to set an onClick (Javascript)
event handler for each of the links, and then use AJAX style stuff to
send the information to PHP on the server side, then PHP can log the
link that was clicked, and keep track of the most clicked links.

Another way to do this is to take the user to a page that would
identify the clicked link (by ID, for example), store the visits data
to a database or a text file and then redirect to the corresponding
news. So, such link might look like this:
<a href="http://www.news.com/redirect.php?news_id=150">read news</a>

Hope this helps.

add to each news item like &clicked=1 and in the page where you display
the news item, checked if clicked exists, if does write it to a file or
a db (obviously with the news item id), if your using mysql, the heap
table type is quite useful, you will however need to move the info to a
more permanent table every x amount of clicks.

Hi,

I previously had some issues with preg_match and many of you tried to help,
but the same problem still exists. Here it is again, if anyone can explain
to me how to get this to work it would be great - otherwise I'll just remove
it as I just spent way to much time on this.

Thanks

Here's the code.

        if(empty($comment)) { $formerror['comment'] = nocomments;
        }
        elseif(!preg_match('|^[a-zA-Z0-9!?#$%^&*();:_.\\\\ /\t-]+$|',
$comment)) {
                                $formerror['comment'] = invalidchars;
        }

This produces an error, which I believe it should not.

Testing 12345. This is a test of the emergency broadcast system.

WAKE UP!!!!!!

attached mail follows:

Maybe you just copied it wrong, but nocomments and invalidchars are not
quoted, or they're constants.

I don't think you have to, but you might need to escape some of the
characters (namely * and .) in your regex. It's been a while, so I'd
have to look it up.

What's the error you are getting?

attached mail follows:

I've been over this a thousand times with various users on this list and
escaping this and escaping that just doesn't matter.

The error is that it thinks valid characters are invalid. In the case of the
example I included, the ! and the period are invalid, which they should not
be.

The nocomments and invalidchars are constants.

As far as I tested, the regular expression works how it is
intended to work.

Maybe this a touch easier to read line do it for you:

  elseif (preg_match('|[^a-zA-Z0-9!?#$%^&*();:_.\\\\ /\t-]|', $comment))

Addendum: I encountered a problem when the string contains linebreaks. Maybe
adding \n\r into the brackets fixes your problem.

Are you running under FreeBSD 6.2 and/or upgraded recently from 5.2.1 to
5.2.2?

I had the same problem on FreeBSD 6.2, with php5 installed from ports
collection after I portupgraded to 5.2.1.

For me it appeared to be some kind weird misconfiguration problem that
happened during the portupgrade...

I had to:

pkg_delete -rv "php5*"
rm -rf /var/db/ports/php5*
rm -rf /usr/local/lib/*
cd /usr/ports/lang/php5
make install clean
cd /usr/ports/lang/php5-extensions
make install clean

A bit harsh, but all of the preg_* errors disappeared since then.

This indeed should be:

rm -rf /usr/local/lib/php/*

instead ;)

Hi,

Your sample text contains newlines. If you wish to allow newlines,
instead of " \t" you should use the whitespace selector "\s"

<?php
$comment = 'Testing 12345. This is a test of the emergency broadcast system.

WAKE UP!!!!!!';
if(!preg_match('|^[a-zA-Z0-9!?#$%^&*();:_.\\\\\s/-]+$|', $comment)) {
    echo 'oops';
} else {
    echo 'ok';
}
?>

Try that code sample, and you'll see that it says "ok"

What exactly are you trying to accomplish with this preg_match()? What
exactly are you trying to filter out? I understand you want to
eliminate "invalid characters" but why are they invalid? I ask because
there may be a simpler way to solve the problem, if you can explain what
the problem is.

Thanks,
Greg

It's 6.2 but PHP 4.4.4.

Basically, I'm not getting any error. The expression just don't match. I
don't know if it should or not.

Haha,

This reminds me of a story about some IRC chat somewhere where someone was
asking how to control a media player thru the command line. It ended up with
him executing rm -rf / as root and then complaining that the machine was
slow when he executed it, and then he disappeared from the IRC... I wonder
why? :)

attached mail follows:

Hi,

I am executing exec('some cool command', $stdout, $exitcode);

That is fine. I get what I in the beginning wanted. However, now I need to
catch the STDERR that the command is generating as well. Some of you might
tell me to redirect STDERR to STDOUT, but that is not possible as I need to
use the STDOUT as is to automate a process.

I know I can do fwrite(STDERR, 'Output some error\n');

So could I fread(STDERR, SOMESIZE)?

Is there anyone with experience of best way of doing this? Should I maybe
use proc_open or something similar and then write it to a file, and then
read that file? Hrm, doesn’t make any sense to do that.

I've rebuilt php5 and apache2.2.4 and still the same issues. what else
could be going on here.

also 'apache restart' is fine but 'apache graceful' core dumps.
