This doesn't seem to be working for me in 3.7.4, and I've tried the hack to get Amazon UK links added, and those won't work either. Maybe I'm doing something wrong?

Hey, I installed the script and its working so far... but when editing a post and clicking on the submit button it turns into the loading symbol for infinite time... but the post already got edited. I contacted the the vB support and they told me its because of this hack
Can somebody confirm that he is having the same problems? Or a fix for this? Please help, I need this working asap!

Regards,

That's what I tried, but it doesn't work. In fact, nothing works. It just won't add the affiliate links to anything.

I've uploaded the PHP file with my aStore ID written in, and uploaded the plugin. How do I get it to re-write the links to include my aStore ID?

Okay, this wasn't working for me in 3.7.4 PL1, and now I've gone to 3.8.0 -- do I have any hope of getting it to work in that version?

Also, I have one further question about the hack on the last page to get it to work with Amazon.co.uk, what exactly do you mean by 'add the bit in the preg_match to work with this'? I'd like to give it one last go before I throw my hands up on this entirely.

Someone port this over to 3.8 please. It is a wonderful hack!

[Claygp]

Are we going to see a 3.8 version??

[veracity024]

the sooner the better for the 3.8 version!

I just PM'd the coder. I offered financial compensation to update the mod, so hopefully that will help!

$associate_id_ and then the .tld with the . replaced by _
$associate_id_co_uk is the UK one.

And of course add the bit in the preg_match to work with this.

Code for the file is thus:

PHP Code:

<?php
function amazon_links($text) {
    $associate_id_co_uk = 'buro9-21'; // or leave empty
    $associate_id_com = 'buro9-20'; // or leave empty

    $replace_targt_urls = true; // true or false

    $replace_src = array();
    $replace_str = array();

    // check for [url="amazon-link"]some text[/url]
    if(preg_match_all("/\[url\=(?:\")?(http:\/\/(?:[A-z0-9\.]+)?amazon\.(co\.uk|com)\/(?:.+))(?:\")?](.+)\[\/url\]/iU", $text, $out)) {
        for($i=0;$i<count($out[1]);$i++) {
            $associate_id = ${'associate_id_'.str_replace('.','_',$out[2][$i])};
            $out[4][$i] = $out[1][$i];

            if($associate_id && !empty($associate_id)) {
                // Look for an asin number
                if(preg_match("/\/[A-Z0-9]{10}(\/)?/", $out[1][$i], $asin) && strpos($out[1][$i], '/review') === false) {
                    if(substr($asin[0], -1) != '/') { $asin[0] .= '/'; }
                    $out[1][$i] = 'http://www.amazon.'.$out[2][$i].'/exec/obidos/ASIN'.$asin[0].'ref=nosim/'.$associate_id;
                } else {
                    $target_url = $out[1][$i];
                    if($replace_targt_urls) {
                        $target_url = preg_replace('/ref\=([a-z0-9\-]{3,})\-([0-9]{2})/iU', 'ref='.$associate_id, $target_url);
                        $target_url = preg_replace('/tag\=([a-z0-9\-]{3,})\-([0-9]{2})/iU', 'tag='.$associate_id, $target_url);
                    }

                    $out[1][$i] = 'http://www.amazon.'.$out[2][$i].'/exec/obidos/redirect?link_code=ur2&camp=1789&tag='.$associate_id.'&creative=9325&path='.urlencode($target_url);
                }

                $replace_src[] = '[url="'.$out[4][$i].'"]';
                $replace_str[] = '[url="'.$out[1][$i].'"]';

                $replace_src[] = '[url='.$out[4][$i].']';
                $replace_str[] = '[url='.$out[1][$i].']';

                $replace_str[] = '[url="'.$out[1][$i].'"]';

                $replace_src[] = '[url='.$out[4][$i].']';
                $replace_str[] = '[url='.$out[1][$i].']';
            }
        }
    } unset($out);
    
    // check for [url]amazon-link[/url]

    // replace the message

    } unset($replace_src, $replace_str);

    return $text;
}
?>

Thanks for the great hack.

Can someone tell me what exactly I am supposed to write into the preg_match section to get this hack to work for my multilevel domain affiliate links if I am using more than one? I have affiliate IDs for .co.uk and .co.jp, but I don't really understand how to write in more than one according to this example, I also can't seem to figure out where I am supposed to put my .de domain in the preg_match section.

Also, I seemed to have discoveed that on my forum (running 3.8.1 PL1) that this plugin will only add the affiliate ID to URLs if they are added raw, but if an Amazon URL is added to text, like this, for example: I Love Lucy, it won't add the Afilliate ID.

Thanks for any help. I really hope this plugin can be updated.
