Disable search engine on search pages
A good idea when trying to get the most out of your blog is usging the meta tag to tell the web bots to search & index your site. But for good SEO you should apply this code in your header.php
file of your WordPress blog.
<?php if(is_search()) { ?> <meta name="robots" content="noindex, nofollow" /> <?php }?>
This will keep your site from getting a hit from bots over duplicate entries. 🙂

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.

Turn your RSS feed into a shortcode
Last week I wrote how to “Use WordPress to print a RSS feed for Eventbrite attendees“. It was pretty popular, but then I found myself in a place that was more annoying. Trying to incorporate that into a blog post or page.
Without having to download a plugin that will allow PHP to be executed inside a post, I would have to create a template file and use that. Which is what I did, and it works just fine. But for some reason I forgot all about shortcodes! With a shortcode, I could generate all the PHP in the functions file and then just call the shortcode when/where I want.
Okay, so lets show the completed PHP code:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' ); $items = array_slice( $rss->items, 0 ); if ( empty( $items ) ) echo '<ul style="list-style-type: none; list-style-image: none; list-style-position: outside;"><li>No items</li></ul>'; else foreach ( $items as $item ) : ?> <ul style="list-style-type:none; list-style-image:none; list-style-position:outside; margin-bottom: 0px"> <li><!--<strong><?php echo $item[ 'title' ]; //User name ?></strong><br />--> <?php echo $item[ 'content' ][ 'encoded' ]; ?> <hr style="border: 1px solid #ddd; margin-bottom: 8px" /> </li> </ul> <?php endforeach; }
Now, this code has to be changed for it to work as a shortcode. We’ll have to return the function and not print/echo it.
I also wanted to be able to use multiple instances of the code with different feeds. To do so I had to create a argument to extract from the completed short code. I found a demo at: Alex Mansfield’s post.
Remember this:
function attendee_feed_print_2009() { global $wpdb; include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( 'http://www.eventbrite.com/rss/event_list_attendees/384870157' );
We are going to update it to read as follows ( changes in bold ) :
function attendee_feed_print_2009( $rss_nbr ) { global $wpdb; extract( shortcode_atts( array( 'rss' => ''), $rss_nbr ) ); include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( $rss );
And the final code with the fields updated to return the arguments ( put into your functions.php file ( in between <?php
?>
) ) :
function attendee_feed_print_2009( $rss_nbr ) { global $wpdb; extract( shortcode_atts( array( 'rss' => ''), $rss_nbr ) ); include_once( ABSPATH . WPINC . '/rss.php' ); $rss = fetch_rss( $rss ); $items = array_slice( $rss->items, 0 ); $rss_html = '<div id="eventbrite-attendee-list" style="clear:both;">'; if ( empty( $items ) ) $rss_html .= '<ul style="list-style:none;"><li>No attendees, yet.</li></ul>'; else foreach ( $items as $item ) : $rss_html .= '<ul style="background:none; list-style:none; margin:0px">'; $rss_html .= '<li style="background:none; list-style:none;">'; $rss_html .= $item[ 'content' ][ 'encoded' ]; $rss_html .= '<hr style="border: 1px solid #ddd; margin-bottom: 10px" />'; $rss_html .= '</li>'; $rss_html .= '</ul>'; endforeach; $rss_html .= '</div>'; return $rss_html; }
And lets not forget to add the shortcode function!
add_shortcode( 'eventbrite-attendees', 'attendee_feed_print_2009' );
Final outcome with look like this `[eventbrite-attendees rss="http://your-rss-feed.com/"]`
I’ve created this into a plugin!
