I found this code online to create a like/send buttons for Facebook to put under my posts on my website. When the user clicks "Like" or "Send" I want the content tags from the website to be automatically input into the user's Facebook post: so the Facebook plug-in/post function will attach the picture and link to the site, and have the tags (already associated with the picture within my site's coding) automatically entered as text into the post. I'm not a programmer and thought this might be a good place to get some help. Does something like this already exist that can be altered/edited? I am not familiar with this, and I'm having difficulty trying to explain it.
Here is the code I have so far.
<!-- Facebook Like+Send script Start -->
<b:if cond="data:post.isFirstPost">
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>
</b:if>
<!-- Facebook Like+Send script End -->
<!-- Facebook Like+Send button Start -->
<div style='float:left;padding:5px 5px 5px 0;'>
<fb:like expr:href='data:post.url' font='' layout='standard' send='true' show_faces='false' width='450' colorscheme='light'></fb:like>
</div>
<!-- Facebook Like+Send button End -->
