Do you want to add the buttons to all the pages of your blog?
If yes, the sharethis plugin settings(http://YOUR WP BLOG/wp-admin/options-general.php?page=sharethis.php)
Automatically add ShareThis to your posts?* Yes
Automatically add ShareThis to your pages?* Yes
should work fine.
But, if you want to add the buttons on some pages only, then please note that displaying sharethis conditionally is not possible with the automatic installation however this can still be done by setting the plugin to not automatically place the buttons and then adding the span tags manually to your templates.
These go on the page where you want the buttons to appear and they also determine what kind of button appears as well as what URL and title it shares. You will have to put 'script tags' in your Main index template(index.php) and 'span tags ' in Single Post template(single.php).
Here is the basic span for just the ShareThis button:
<span class="st_sharethis" st_title='<?php the_title(); ?>' st_url='<?php the_permalink(); ?>' displayText="ShareThis"></span>
You can change the class of the span to determine the button that appears. For example class="st_twitter" will make a twitter icon and class="st_email_vcount" will make a email vertical counter button.
However, adding code in index.php and single.php will not display sharethis buttons on the blog page but will show buttons whenever an individual post is opened.
If you wish to display sharethis buttons on the blog page ,you will have to put 'span tags' in (loop.php).
1. put span tags just above the line "<div class="entry-utility">" to display buttons at the end of each post on the blog page.
<span class='st_sharethis' ></span>
2. to display buttons at the beginning of each post on the blog page,put span tags just below the lines
<h2 class="entry-title"><a>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>
<?php twentyten_posted_on(); ?>
</div><!-- .entry-meta -->
<?php if ( is_archive() || is_search() ) : // Only display excerpts for archives and search. ?>
For Example:You will have to put a sharethis <span> tags in a conditional block with condition:
if (<?php the_permalink(); ?> is equal to 'Title of page to which you wish to add sharethis buttons')
//Sharethis <span> tags
Hope this helps.
