Referral Script... If you help, I'll mention you by name!

[lunchboxpad]

I'm new to the PHP world, and just added the first PHP anything to my site. Its a simple code that saves the last X number of referrals so visitors of my site can see them.

The script works great, the only problem is that some of the referring URLS can be quite long, and I would like to add the option of only allowing, say 60 characters of the URL to display, and then have a "..." appended to the end of that link. But, right now, the script uses the same variable for the a href link and the title.

I would appreciate anyone who might want to help me with this. It seems like something that could be done quite easily.

I would include a thank you on my site for your help.

My link is included below, so you can see the example (See the last 20 referrals...)

Lunch Box Pad web site

I can send you the files, there are 4 of them if you need to look at them.

I REALLY REALLY want to fix this!!!!

Thank you!

Something like this should work:

<?
// fast dirty code, just so that you get how the functions work.
// $ref_link == the referal
// $href == what is shown on page

if(strlen($ref_link) > 60)
   $href = substr($ref_link, 0, 60) . "...";
else
   $href = $ref_link;
?>

EDIT: oh.. you wanted the "..." too =) added that.

thanks for the quick reply cookie! I've tried adding your code, but don't get anything to work. I have included the code for the files:

This is the file show-refs.php (the file that lists the actual referrers)

<?php
$reflog = "reflog.txt";
?>

<?php
$rfile = file($reflog);
foreach ($rfile as $r) {
$r = chop($r);
if ($r <> "Direct request") echo "
<table width=\"100%\"cellspacing=0 cellpadding=2 border=0>
<tr>
<td width=14><img width=14 height=16 src=/home/images/bullet_box.gif alt=\"\"></td>
<td align=left class=smalltext><a href=\"$r\">$r</a></td>
</tr>
</table>
\n";
}
?>

This is the main script file, reflog.php

<?php

// Name of referrer log file
$reflog = 'reflog.txt';

// Name of semaphore file
$semaphore = 'semaphore.ref';

// Maximum number of referrers to log
$maxref = 20;

// Domain name of this site (minus "http://www.")
$mydomain = 'lunchboxpad.com';

// From whence did Bunky come?
$ref = getenv("HTTP_REFERER");

// Cover me. I'm going in.

if (($ref) and (!strstr($ref, $mydomain))) { // if there's a referrer, and it's not someone bouncing around this site
$ref .= "\n"; // append a line feed
$sp = fopen($semaphore, "w"); // open the semaphore file
if (flock($sp, 2)) { // lock the semaphore; other processes will stop and wait here
$rfile = file($reflog); // read the referrer log into an array
if ($ref <> $rfile[0]) { // if this referrer is different from the last one
if (count($rfile) == $maxref) // if the file is full
array_pop($rfile); // pop the last element
array_unshift($rfile, $ref); // push the new referrer onto the front
$r = join("", $rfile); // make the array into a string
$rp = fopen($reflog, "w"); // open the referrer log in write mode
$status = fwrite($rp, $r); // write out the referrer URLs
$status = fclose($rp); // close the log
}
}
$status = fclose($sp); // close the semaphore (and release the lock)
}
?>

In the page you want the referrals tracked for, you put this code at the top of the page (this is what I have on my main page)

<?php
include('reflog.php');
?>

I have included all the files. If anyone can get my original problem figured out, I'd be very grateful. All the files reside in the same directory of the file being tracked.

If you can tell what to add and where to add it, so I can reduce the long URLS to 60 characters, that would be great. Also, I would like to append 3 periods "..." at the end of that 60 character limit.

Thank you in advance.

in show-refs.php,

change your code so it looks like this:

<?php 
$reflog = "reflog.txt"; 
?> 

<?php 
$rfile = file($reflog); 
foreach ($rfile as $r) { 
    $r = chop($r);
    if(strlen($r) > 60) {
        $ar = substr($r, 0, 60) . "...";
    }
    else {
        $ar = $r;
    }
    if ($r <> "Direct request") echo "
<table width=\"100%\"cellspacing=0 cellpadding=2 border=0> 
<tr> 
<td width=14><img width=14 height=16 src=/home/images/bullet_box.gif alt=\"\"></td> 
<td align=left class=smalltext><a href=\"$r\">$ar</a></td> 
</tr> 
</table> 
\n"; 
    }
}
?>

basically $ar is a copy of $r. but it will show only 60 chars of the url and a ... if it's longer than 60.

Thanks for the quick reply Slinky!

I've changed the code exactly as you said, but no referral links show.

I've included a link to the script. If anyone can download this, and get it to work so that it only shows 60 characters max of any title and appends the 60 limit with "...", please give it a try.

Thank you for the people who have already tried to help.

HERE IS THE SCRIPT IN ZIP FORMAT

I GOT IT TO WORK!!!! THANKS SLINKY!!!! Please e-mail me your name and you can include a link. I'll add your name to my "Thank you" page as soon as it's up!

All I had to do was remove one of the "}" at the end of the code.

How exactly did you get it to cut it down? And how would I get it to just cut all the way down so as not to inlcude any subfolders like.. instead of ..
