I want to have a button to bookmark or add a page to delicious but I don't want it to bookmark the page the button will be on but the page before.

Is this possible and if so how?

Thanks.

So if somebody arrived on your page from a search engine or a page on some other site, you want to bookmark the other site????

Fair point.

The page can only be gotten to via another page.

website.com has a link to webstite.com/login

I don't want people to try to bookmark webstite.com/login as it wont work if they arrive that page via a bookmark - they have to go via website.com

So when they are on webstite.com/login I want a button that bookmarks website.com for them.

Ok not necessarily the previous page, more of a "Send a URL I choose" kind of button.

<a href="http://del.icio.us/post?url="URL_goes_here" title="Post this to Delicious" ><img src="path_to_image" alt="Post this to Delicious" title="" ></a>

Yes that's exactly it!

Would it be possible to do the same thing with the AddThis bookmark widget:

<!-- AddThis Button BEGIN -->
<script type="text/javascript">var addthis_pub="fylanj";</script>
<a href="http://www.addthis.com/bookmark.php?v=20" onmouseover="return addthis_open(this, '', '[URL]', '[TITLE]')" onmouseout="addthis_close()" onclick="return addthis_sendto()"><img src="http://s7.addthis.com/static/btn/lg-bookmark-en.gif" width="125" height="16" alt="Bookmark and Share" style="border:0"/></a><script type="text/javascript" src="http://s7.addthis.com/js/200/addthis_widget.js"></script>
<!-- AddThis Button END -->

yep, just replace the [url] placeholder with the real URI

Thanks!
