On April, 25 facebook add into their social plugin the new “Send” button. The difference between “I Like” and “Send” button is that with the like button you publish a link on your wall, with the Send Button you will be able to send a private message to a specific contact, friend or email address.

To a better facebook experience you may add the open graph tag. Continue reading →

Add Send Button Via Plugin:

I wrote a plugin called Facebook Send for WordPress that allow you to add the send button on your theme.

Add Send button Via Code:

Open your function.php and:

Add the Open Graph tag:

function wpc_fbmetatag() {
$large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');

?>

<!-- START Facebook Open Graph meta tag-->

<meta property="og:title" content="<?php the_title(); ?>" />
<meta property="og:url" content="<?php the_permalink(); ?>" />
<meta property="og:site_name" content="<?php bloginfo('name'); ?>" />
<meta property="og:description" content="<?php the_title(); ?>" />
<meta property="fb:app_id" content="<?php echo get_option('wpc_fcw_appid'); ?>">
<meta property="fb:admins" content="<?php echo get_option('wpc_fcw_adminid'); ?>"/>
<meta property="og:image" content="<?php echo $large_image_url[0] ?>"/>

<!-- END Facebook Open Graph meta tag-->
<?php }

add_action('wp_head', 'wpc_fbmetatag');

And now add the button:

function wpc_fb_sendbutton() { ?>
<div id="fb-root"></div><script src="http://connect.facebook.net/en_US/all.js#appId=INSERT APP ID HERE&amp;xfbml=1"></script><fb:send href="<?php the_permalink(); ?>" font=""></fb:send>
<?PHP } ?>

And Now wherever you want in your theme:

<?php if ( function_exists('wpc_fb_sendbutton()')) {wpc_fb_sendbutton} ?>
