i'm working on a website that is built on WordPress & the Genesis Framework. I'm looking to display an RSS feed From Feedstich within WordPress pages in the middle of the content. What is my best bet of doing this, is there a plugin that can use shortcodes or is there a way I can use php in pages to display them?

You could use a wrapper for fetch_feed() as a simple shortcode.

Very basic example; see the RSS widget code for more options.

<?php # -*- coding: utf-8 -*-
/**
 * Plugin Name: T5 Feed Shortcode
 * Description: Use <code>[feed url="http://wordpress.stackexchange.com/feeds"]</code> to display a list of feed items.
 */

add_shortcode( 'feed', 't5_feed_shortcode' );

function t5_feed_shortcode( $attrs )
{
    $args = shortcode_atts(
        array (
            'url' => 'http://wordpress.stackexchange.com/feeds'
        ),
        $attrs
    );

    // a SimplePie instance
    $feed = fetch_feed( $args[ 'url' ] );

    if ( is_wp_error( $feed ) )
        return 'There was an error';

    if ( ! $feed->get_item_quantity() )
        return 'Feed is down.';

    $lis = array();

    foreach ( $feed->get_items(0, 20) as $item )
    {
        if ( '' === $title = esc_attr( strip_tags( $item->get_title() ) ) )
            $title = __( 'Untitled' );

        $lis[] = sprintf(
            '<a href="%1$s">%2$s</a>',
            esc_url( strip_tags( $item->get_link() ) ),
            $title
        );
    }

    return '<ul class="feed-list"><li>' . join( '</li><li>', $lis ) . '</ul>';
}

I think this makes sense, just add these lines of code to my functions file (or a custom plugin) then use the shortcodes? @torscho –  Zach Russell May 15 '13 at 19:16
    
The code is a complete plugin. Install, activate, and it works. Never put a shortcode into a theme. –  toscho May 15 '13 at 19:18
