If you want to have the "Share this page" and "Tell a Friend" feature in your Ecwid store, you can get it using the AddThis widget that works with Ecwid.
Demo
http://www.ecwid.com/playground/addthis/ (you will see three different buttons)
Unfortunately AddThis has an issue with the tracking changes of URL hash. So we will describe how to overcome this issue and integrate AddThis with Ecwid in a correct way.
Instruction
1. First please create a new directory on your server called "ecwid-js". It should be created in the root web directory(usually httpdocs, htdocs or public_html)
2. Download this file: ecwidMods.js on your computer.
3. Upload it to the created ecwid-js directory.
4. Get the code of the AddThis button from their site: http://www.addthis.com/web-button-select
5. Enclose the generated code you got from AddThis with the <div id="ecwid_addthis"> and </div> tags. I.e.:
<div id="ecwid_addthis">
... some AddThis code here
</div>
For example:
<div id="ecwid_addthis">
<!-- AddThis Button BEGIN -->
<a class="addthis_button" href="http://www.addthis.com/bookmark.php?v=250&username=qetzal">
<img src="http://s7.addthis.com/static/btn/v2/lg-share-en.gif" width="125" height="16" alt="Bookmark and Share" style="border:0"/>
</a>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=qetzal"></script>
<!-- AddThis Button END -->
</div>
6. Add the following lines to your page:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script src="/ecwid-js/ecwidMods.js" type="text/javascript"></script>
<script>
function ecwid_change_addthis_url(page) {
addthis_share.url = window.location;
$j('#ecwid_addthis a').each(function() {
if (this.share.url)
this.share.url = String(window.location);
});
}
addMod(ecwid_change_addthis_url, 'allPages');
</script>
7. Save the changes and reload your store page. That's all, feel free to test your AddThis button.
