hey!

vbulletin stores the posts in the database and uses a cache (table: postparsed). To clear the cached old/new urls you have truncate this table.

this means... no cached postes will only be overwritten in the postparsed table. the original post is not overwritten (table: post).

after installing only new posts will be overwritten, but you can truncate the postparsed table as explained.

i hope this helps.

Has anyone got this working with .co.uk yet?

Does this work with 3.70 gold?? This is exactly what I'm looking for.

yep working just fine

[Phillip Chapman]

Can someone confirm whether or not this works with 3.6.10? Should my associates id be visible in the actual amazon URL if working properly?

[Phillip Chapman]

It's working now. We noticed the links don't change in preview, only when a message has been posted.

I've got this working for .co.uk

You can easily add .ca, .de or any two level .tld like .co.uk to this by adding:
$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) {

Thanks for the great hack.

[pete_brady]

i think i love you

edit: hmm i must be doing something wrong

[pete_brady]

ok did some more tests.

the hack works when i post a raw link, but not when i post it like so.

Previously it worked both ways. Not that i'm complaining, though!

[ArnyVee]

Is this mod still functioning alright for folks? Since there hadn't been a post in nearly three months, I wanted to ensure that everyone was okay before proceeding.
