Adds a Facebook Share button to your WordPress posts
FB Share is a WordPress Plugin, which lets you add a Facebook Share button for your WordPress posts, together with the total number of share.
There are three ways you can add the facebook share button. Automatic way, manual way and using shortcodes
Install the Plugin and choose the type and position of the button from the Plugin’s settings page. You can also specifically enable/disable the button for each post or page from the write post/page screen.
If you want more control over the way the button should be positioned, then you can manually call the button using the following code.
if (function_exists('fbshare_button')) echo fbshare_button();
You can also place the shortcode [fbshare] anywhere in your post. This shortcode will be replaced by the button when the post is rendered.
