Tips & Tricks
Limit the characters that display on the_title
Ever wanted to display the title of a post somewhere but limit the amount of characters that are shown? For instance, this post has a very long title, and if I were to use <?php echo the_title() ?>
it would show as follows: Limit the characters that display on the_title.
That may not fit well on one line in lets say a widget or small width div
. So here is a neat trick you can use:
<?php $title = the_title('','',FALSE); echo substr($title, 0, 11); ?>
Pretty simple huh, just note the bold numbers, in this case 11 character would output like this: Limit the c.

Tips & Tricks
Remove spaces when echoing the_title
Ever wanted to print or echo the WordPress title attribute without spaces?
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; ?>&<?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.
Tips & Tricks
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.
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.
Tips & Tricks
Add a shortcode
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. :)

Cheers. Very useful. 🙂
I don’t suppose could help me with adding a little extra to this. I want to put “…” at the end if the amount of chars in the title exceeds the cut off point.
