If you've been building your site using Drupal 7 and wanted to add ShareThis buttons via module, you've probably seen that only version 6 is supported at the moment.
Fortunately, this is not a big problem as you can add simple code to your template and have ShareThis in no time.
1 Get the code
Go to http://sharethis.com/publishers/get-sharing-button and choose Any Website under section 1, choose button type and style (Horizontal Counters in my case), and get the code.
2 Add code to template
ShareThis provides two "e;sets"e; of code. Buttons that go onto the page, and serve as placeholders for buttons, and scripts that go into the head of the page.
The first one is added to node.php or wherever you want the buttons to be shown as such:
<div class="share-buttons">
<span class="st_twitter_hcount" displayText="Tweet"></span>
<span class="st_facebook_hcount" displayText="Share"></span>
<span class="st_email_hcount" displayText="Email"></span>
<span class="st_sharethis_hcount" displayText="Share"></span>
</div>
Code language: HTML, XML (xml)
The second one can't be added in form of a script, but Drupal 7 provides excellent ways of inserting JS onto pages described here http://drupal.org/node/751744 .
In this case, you should copy parts of provided code as such in template.php:
drupal_add_js('&lt;a href="http://w.sharethis.com/button/buttons.js"&gt;http://w.sharethis.com/button/buttons.js&lt;/a&gt;', 'external');
drupal_add_js('stLight.options({publisher:\'PUBLISHER-ID\'});', 'inline');
Code language: HTML, XML (xml)
This is all there is to it. Few lines of code and no modules are needed.
