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” ;-)

  1. Any tips for making this work in a widget? I tried your suggestion, as well as some other ideas, and when I click on the like button, the number appears briefly and then disappears.

  2. Und alle haben den tollen Bug des Code-Generators uebernommen:
    “height:px;”

    Bitte mal durch einen richtigen Wert ersetzen, ansonsten nimmt das Plugin einfach zu viel Platz weg (zumindest bei mir im Chrome, andere Browser nicht getestet)…

  3. Nice. Thanks for this!

    Is there any way I can add the like button at the end of every single post, but on the main page?
