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.

Fixing plugins not compatible with hybrid 0.4.2
Hey everyone, as you may have noticed I have a running on the site. While everything almost everything moved over smoothly, there was an issue with how my parent theme striped text in typography. This caused some plugins, like cformsII to not be allowed to print to the screen. Justin had helped to find a fix to filter the hybrid_typography
function.
Originally this function filtered out and changed some text that would not validate as XHTML. This had to be removed by running a new function in the child theme’s function.php
file.
add_action('init', 'remove_typography'); function remove_typography() { remove_filter('the_content', 'hybrid_typography', 11); }

Add the twittar plugin for WordPress w/ comment threading
I talked about the Twittar plugin in a previous post. But learned that the read me text file was only useful for installing the necessary php
code into WordPress themes that don’t have comment threading enabled.
Since most new themes past version 2.7, pull the comments section from functions.php
file, that is where you have to edit the avatars in order to show the twittar settings.
First open you functions.php
, and look for a line of code that says:
function custom_comment()
This is where your new comments are pulled from when you have the threaded comments enabled.
Now just find <?php echo get_avatar( $comment, $args['avatar_size'] ); ?>
& replace with <?php twittar(70, "", "", "avatar avatar-70 photo", 1, "R"); ?>
. Keep in mind that you will need to edit the Twittar setting to fit your site.
Tips & Tricks
Styling your ordered & unordered list items into 2 columns
In a previous post I showed you how to create a custom widget, then I showed you how to create a widget for your monthly archives, and limit the month’s that show. I am showing the past 4 months in my widget at this time.
One of my readers: Alex asked:
How did you make the archives widget to show the dates separately into two columns?
Now I will show you a CSS trick to create this effect:
First we will give the unordered list a width of 100%:
ul#archives { width:110%; }
Then we will style the <li>
nested inside.
ul#archives li { display:inline; float:left; width:120px; }
And that is it. Please make sure that you clear the float
after your closing </ul>
