How to: Create a fbshare.me shortcode
Social networks are everywhere. I am sure you’re on facebook. Well why not at a facebook share script to your site?
Don’t know PHP that well?
Well here is a simple way to add a share script like fbshare.me to your site, via shortcodes.
Paste the following code in your functions.php file in order to create your shortcode:
function fbshare_script() { return '<div class="fbshare"><script src="http://widgets.fbshare.me/files/fbshare.js"></script></div>'; } add_shortcode( 'fbshare', 'fbshare_script' );
Once done, you can display the facebook share button anywhere on your posts. In WordPress editor, make sure you are in HTML mode and insert the following: [fbshare]
.
When your post will be published, the shortcode will be replaced by the fbshare.me button.

Pulling custom fields from outside the loop
In the last post “Creating a custom widget” I showed you how to create a custom widget. Well in this post I will show you how I used my custom widget to display all post with a certain custom field from outside the WordPress loop.
In the last post I used this tag:
<?php include(TEMPLATEPATH . '/includes/showcase.php'); ?>
Now I will show you what the file showcase.php
has:
<ul> <?php global $wpdb; $sql = "SELECT wposts.* FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta WHERE wposts.ID = wpostmeta.post_id AND wpostmeta.meta_key = 'gallery-url' AND wposts.post_status = 'publish' AND wposts.post_type = 'post' ORDER BY wposts.post_date DESC LIMIT 8"; $pageposts = $wpdb->get_results($sql, OBJECT); $output = $pre_HTML; foreach ($pageposts as $post) : setup_postdata($post); ?> <li><a href="<?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>" title="Link to <?php the_title(); ?>"> <img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php the_title(); ?>" /></a></li> <?php endforeach; ?> </ul>
That’s it! The most important item you may want to change for your own custom field is the line : AND wpostmeta.meta_key = 'gallery-url'
. Where you would change the text in bold to match your own custom field value.
Update:
Check out Austin from PressedWords comment below.
With his great advise I was able to figure out why all my attempts to use the query_post weren’t working. it came down to this line of code: <?php echo get_post_meta($post->ID, "gallery-url", $single = true); ?>
, that was what I had in my code, and the $post->ID
is the reason my code would not echo or print the custom field’s value. Solution? replace $post->ID
with get_the_ID()
. HA, so simple.

Creating a custom widget
Today let’s learn a simple quick trick on how to create a custom widget. For my example I will show you how I created my Showcase widget located in the middle, to the right of the posts.
First under your functions.php
file type in the following:
<?php // Custom Widget function MyCustomWidget() { ?> <li class="widget"> <h2 class="heading">Latest Showcase</h2> <ul> <?php include(TEMPLATEPATH . '/includes/showcase.php'); ?> </ul> </li> <?php } register_sidebar_widget('The Custom Widget for Showcase', 'MyCustomWidget'); ?>
- Always make sure your code is between the
<?php
and?>
for it to work. - Once we call the function, the rest is assuming html code that you may or may not need.
- For instance, you may just put in a picture and call it a day. But my code starts with
<li<
because my sidebar’s start and end with<ul<
. - Any way, once your done, just set the final “
register_sidebar_widget('the widget title', 'the name of the function');
“
That’s it! Now you have a custom widget with what ever you want!
Tips & Tricks
Display custom url if comment authors url is blank
Here is a nifty trick for your comments.php
template. If someone comes to your site and leaves a comment but doesn’t leave a url back to there site, the default link that is shown in place of the php code comment_author_url
is the current page link.
That might not look good. So, here is a little trick that I just implemented into my site. Besides installing the twittar plugin and pulling Twitter avatars I wanted to use the image itself for the authors url like. But if the author doesn’t have a Twitter avatar or a Gravatar it will display a default Gravatar that I set. If the default Gravatar is shown, usually the author will not leave a url link.
I would like to link the image to Gravatar.com so that they can get an image attached to their email address. So.. here is the code:
<?php if($comment->comment_author_url != "") { ?> <a href="<?php comment_author_url(); ?>"><?php gravatar(); ?></a> <?php } else { ?> <a rel="nofollow" href="http://gravatar.com" title="Get a Gravatar today!"><?php gravatar(); ?></a> <?php } ?>

I didn’t even know you could do this. I’d seen a script to do something similar but it was written in some complicated CURL/PHP code. So thanks for this!
