Sick of images being to large for the content area?
Have you ever uploaded an image that might have been a tad bigger than the width of your content area? I know I have! So here is a little CSS fix to handle these situations.
.post img { max-width: 600px; height: auto; }
That’s it, really simple huh. Just make sure that you change the .post
to the correct body class(which starts with a “.“) or body ID(which starts with a “#“).
Would you like a quick explanation?
The CSS is just telling any image inside the class of .post
to not be more than 600px wide. By the way make sure you change it to fit the dimension of your content width. And the height attribute is set to auto to automatically change the height to match the new width. 🙂

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!

Tips & Tricks
Use WordPress to print a RSS feed for Eventbrite attendees
Today I was working on the WordCamp.LA site. I was trying to show the “attendee list” on the attendees page with out having to update the page every day.
Since I am using EventBrite to promote and sell ticket to the event I can collect info from there list. Evey one who purchases a ticket gets put into the ticketed database which you can view with either RSS or OPML.
I chose to use RSS and the WordPress core file rss.php
.
In the functions.php file I’ve added this function:
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 );
Where I’ve named my function, and included the core RSS file from WordPress. I also told it to fetch the feed from the address (alternatively you can use any feed link you like).
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;
I then added the core style to fit this current feed.
And the final out come looks like 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' ); $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; }
Don’t forget to wrap the code in <?php
?>
I want to thank John Kolbert for helping me with printing the content:encoded
portion. http://pastebin.com/m1588fb30

Hi there, found you through a re-tweet from Lyndi. I love this fix but I am very code-illiterate. Also, attempting to learn XHTML instead of HTML. Where would this go, in the Stylesheet.php or would it go in the post where the image is
It seems like it would go in the style sheet as an overall rule, right?

I probably should have written that. Any way, this CSS should go into either an external stylesheet (like, style.css) or in the page head in between

Oops. I did paste my code from an image in one of my posts and it did not show on my previous comment.

I was searching the internet trying to find an easy way to do this. In the past I was loading and reloading my images to make them fit properly. I have bookmarked your site and will check it out more in the future.
