# Need help editing function

 *  Resolved [dubbinz](https://wordpress.org/support/users/dubbinz/)

 * [12 years, 11 months ago](https://wordpress.org/support/topic/need-help-editing-function/)
 * I have a code snippet which I placed in my functions.php The function adds next/
   previous to posts using shortcodes
 * here is the code
 *     ```
       add_shortcode( 'prev', 'prev_shortcode' );
       add_shortcode( 'next', 'next_shortcode' );
       function next_shortcode($atts) {
           global $post;
           ob_start();
           next_post_link( '<div class="nav-next">%link</div>', 'Next post link' );
           $result = ob_get_contents();
           ob_end_clean();
           return $result;
       }
   
       function prev_shortcode($atts) {
           global $post;
           ob_start();
           previous_post_link( '<div class="nav-previous">%link</div>', 'Previous post link' );
           $result = ob_get_contents();
           ob_end_clean();
           return $result;
       }
       ```
   
 * What I want to do is edit this code so it only cycles through one category in
   date order which I assume is default anyway. I am limited in my ability with 
   php so I need help to accomplish what I want. can anyone help?

 * Here you go:
 *     ```
       add_shortcode( 'prev', 'prev_shortcode' );
       add_shortcode( 'next', 'next_shortcode' );
       function next_shortcode($atts) {
           global $post;
           ob_start();
           next_post_link( '<div class="nav-next">%link</div>', 'Next post link', true );
           return ob_get_clean();
       }
   
       function prev_shortcode($atts) {
           global $post;
           ob_start();
           previous_post_link( '<div class="nav-previous">%link</div>', 'Previous post link', true );
           return ob_get_clean();
       }
       ```

 * There is an optional third parameter in [next_post_link()](http://codex.wordpress.org/Function_Reference/next_post_link)
   and [previous_post_link()](http://codex.wordpress.org/Function_Reference/previous_post_link)
   to indicate whether the next/prev post must be within the same category as the
   current post. Default is false.

    like I said I have
   no idea how to edit it so I completely confused by the response. I know that 
   the changes I need have to be in the () but I have no idea what to put or how
   to edit it.
 * Can you give me an example of the edited version of the code snippet so i can
   understand?

 * Just replace your old code (the whole thing from your first post) with my code(
   the whole thing from my response).

 * Specifically, I changed this:
 * `next_post_link( '<div class="nav-next">%link</div>', 'Next post link' );`
 * …to this:
 * `next_post_link( '<div class="nav-next">%link</div>', 'Next post link', true );`
 * …for both the next and previous post functions.
 * I also cleaned up the code a bit, using `ob_get_clean()` instead of all that `
   $result` business. But that was just an added bonus. 🙂

 * [@shaun](https://wordpress.org/support/users/shaun/) Scovil sorry shaun but when
   I responded I only saw your 2nd post, for whatever reason I couldn’t see your
   first response so I was immediately confused. thanks for the help.
