 * I get the basic idea of filters, but I’m stumped on filtering an array:
 *     ```
       function genesis_post_categories_shortcode( $atts ) {
       	$defaults = array(
       		'sep'    => ', ',
       		'before' => __( 'Filed Under: ', 'genesis' ),
       		'after'  => '',
       	);
       ```
   
 * _[Moderator Note: Please post code or markup snippets between backticks or use
   the code button.]_
 * How do I filter only the ‘before’ part of this function?
 * Thanks in advance.

 * Have you tried the support offerings of StudioPress, since this function is part
   of the commercial Genesis Theme?

 * Hi,
 * I think you want the [apply_filters](http://codex.wordpress.org/Function_Reference/apply_filters)
   function…
 * Here’s how your array will look with this filter in place:
 *     ```
       function genesis_post_categories_shortcode( $atts ) {
       	$defaults = array(
       		'sep'    => ', ',
       		'before' => apply_filters( 'filter_name', __( 'Filed Under: ', 'genesis' ) ),
       		'after'  => '',
       	);
       ```
   
 * Just replace ‘filter_name’ with the name of the filter you wish to apply.
 * In addition be sure whether the filter you are using requires additional variables
   as per the codex page I linked to above 🙂
 * Hope this helps!
 * – Greg
