I want to use some shortcode functionality on excerpts posted on the home page. I know this can be a bit tricky, but this fellow claims to have figured it out:
When displaying the postís excerpt, Wordpress uses a function called the_excerpt(). Here it is in the default sandbox template:
The problem with the_excerpt is that is echoes the excerpt directly to the screen. In order to return the excerpt value as a string we need to use get_the_excerpt(). Next after checking the shortcode API, I discovered a function that will run all the shortcodes on a given string and return the output as a string, do_shortcode().
the_excerpt(''.__('Read More <span class="meta-nav">»</span>', 'sandbox').'') ;
So all we need to do now is combine these two functions, and move it into the template:
And there it is!
I haven't been able to experiment with this too much because I wanted to know WHERE to place this before I potentially had to revert to backup files. He's saying move it into the template -- does that mean a Body HTML insert? Or should I write it directly into the index.php file, and if so, where?
