Integrate Facebook’s “Like” Plugin into WordPress

Facebook recently announced the take-over of the internet with the introduction of the yet infamous “like”-button. Nevertheless, here is how you can add your own dynamic like-button for WordPress.

If you use Facebook’s generator here, you’ll get some content very similar to mine:

<iframe src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fcordobo.com%2F&amp;layout=standard&amp;show-faces=true&amp;width=450&amp;action=like&amp;colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:500px; height:60px"></iframe>

Note: I highlighted the parts I replace in the next step

This would be fine, if you had only one page on your website, as the plugin only shows the url you have entered in the generator – no dynamic pages. So here’s how you can add some dynamic flavour to your new button:

Replace the following code

[…]like.php?href=http%3A%2F%2Fcordobo.com%2F

with

[…]like.php?href=<?php echo urlencode(get_permalink($post->ID)); ?>

insert it into your theme’s single.php and upload it to your server.

The final code, ready for copy & paste

This is the final code you can use in your own WordPress installation without further modifications (except the width and height). Insert it into your single.php and upload the modified file to your server.

<iframe src="http://www.facebook.com/plugins/like.php?href=<?php echo urlencode(get_permalink($post->ID)); ?>&amp;layout=standard&amp;show-faces=true&amp;width=500&amp;action=like&amp;colorscheme=light" scrolling="no" frameborder="0" allowTransparency="true" style="border:none; overflow:hidden; width:500px; height:60px"></iframe>

Note: I highlighted the parts I replaced

In case you use some caching plugin, clear the cache and see the magic as it happens.

If you like it, click on “like” ;-)

  2. Any way to add it to the Blogger pages? I am not very computer savvy so if this all meant you can also use it on Blogger, I def missed it…Thanks!

  3. Hi there! Thank you, Andreas for the code. I have tried it. I have this website that I am working on and I am trying to put the facebook plugin on the website. It works, if the user who is online on facebook, then I see the thumbnail picture. If I am not logged in to facebook, I cannot see the thumbnail picture.

    And secondly, when I go to my client’s facebook, I am not accounted for.

    Actually, it defeats the purpose.

    Thanks anyway.

    1. Hi eve,

      that’s exactly how facebook’s “like”-button is intended to work – you have to be logged in and you see your friends pictures only (at least by now).

      There are although an issue with the correct amount of people who clicked the “like” button, which is an issue FB is working on.

  4. Sorry if I’m repeating myself, but my iphone is giving me static when I try to post …

    … anyway, you can ditch other comments.

    Mostly I wanted to say that I liked your caching suggestion very much.

    It makes me think I want to add that capability to my FaceBook Like Button Plugin for WordPress I released last week.
