Use WordPress to print a RSS feed for Eventbrite attendees

Published

on

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

How to: Display RSS feeds from anywhere

Published

on

Here is a simple way to display any RSS feed in your WordPress blog.

<?php include_once(ABSPATH . WPINC . '/rss.php');
	$rss = fetch_rss('http://feeds2.feedburner.com/WPCult');
	$items = array_slice($rss->items, 0, 4);

		if (empty($items)) echo '<li>No items</li>';
		else
			foreach ( $items as $item ) : ?>
            <a style="font-size: 14px;" href='<?php echo $item['link']; ?>' title='<?php echo $item['title']; ?>'><?php echo $item['title']; ?></a><br /> 
            <p style="font-size: 10px; color: #aaa;"><?php echo date('F, j Y',strtotime($item['pubdate'])); ?></p>
            <p><?php echo substr($item['summary'],0,strpos($item['summary'], "This is a post from")); ?></p>
            <?php endforeach; ?>

The first step is to include the WordPress file rss.php then will apply code after to style the feeds.

Of coarse I forgot to mention, change the RSS feed to the feed you want to pull.

Published

on

In WordPress, when you use wp_page_menu your anchor attribute’s usually carry a title with the same name. I’m not sure if it’s correct to do this, but it bother me when I hover over a page menu navigation link and I get a hover of the title.

So on my site I used jQuery to remove the title:

$("#nav a").removeAttr("title");

Pretty simple huh?

Published

on

Over the weekend, I attended WordCamp Denver, and I was asked by John Hawkins how to force links to open in a new tab with out editing the source code. So, today lets learn a simple jQuery trick to open all external links in your site in a new tab or window. We are going to make sure you have jQuery active on your site, you can do this easily in WordPress, since it’s bundled with the latest installations. Use this code in your header: <?php wp_enqueue_script('jquery'); ?> then, below the wp_head add the following:

<script type="text/javacript">
var $j = jQuery.noConflict();

$j(document).ready(function() {
//external attribute
    $j("a:not([@href*=http://YOURSITE.com/])").not("[href^=#]")
        .addClass("external")
        .attr({ target: "_blank" });
    }
);
</script>

That’s it, just make sure you change the http://YOURSITE.com to your website.

Update

If you like you can remove the var $j = and replace all $j with simply just $
