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.

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. :)
