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.

    Very cool – I had no idea this functionality was built in. I see quite a few projects where people want this type of thing built, and I had assumed you’d have to build your own parser.

    Does anybody know how long Magpie has been in wordpress? This could have saved me lots of time..

Remove spaces when echoing the_title

Ever wanted to print or echo the WordPress title attribute without spaces?

Published

on

This little trick can be useful for calling custom functions and printing the title with out spaces for W3C compatibility. I used this trick in a new theme called Galleria, which will be out for public download in the coming days.

Using this comes in handy for a delicious text link:

<?php $title = get_the_title(); ?>
<a href="http://del.icio.us/post?url=<?php echo $title; ?>&amp;<?php echo str_replace(" ", "%20", $title); ?>">
Bookmark This (<?php echo $title; ?>)</a>

What I am doing is calling $title = get_the_title(); and using str_replace(" ", "%20", $title); to replace empty spaces with a %20, which is used in URL encoding empty spaces.

Alternatively you can use a dash or underscore.

Thanks to Jason Boyle for his adaption.

Display the_excerpt only if there is text

Have you ever wanted to display the excerpt only if you write one? A simple couple lines of code can display the_excerpt any where you like.

Published

on

In my new theme, I am using this coded trick to display the excerpt on a single post only if I’ve got text inside. Usually if you use the_excerpt and you don’t have one, it will fake one for you.

This is not something that I wanted to do on the single post page. So I used the following code to check if the excerpt existed.

if ( !empty( $post->post_excerpt ) ) :

Once this action is taken into account, you can factor in what code you want to out put if the post_excerpt isn’t empty.

if ( !empty( $post->post_excerpt ) ) :
	the_excerpt();
else :
	false;
endif;

The above code checks if there is an excerpt and print’s it to the screen. If there isn’t an except, it doesn’t do anything.

This is a simple one.

/**
 * Your Blog title

function my_blog_title() {
	$blogname = get_bloginfo('name');
    return '<span class="blog-title">' . $blogname . '</span>';
}		  	
add_shortcode('blog-title', 'my_blog_title');

Just add this to your functions.php file and then add [blog-title] in any post or page and it will return your Blog Title. :)
