I know how to "set" the excerpt length for posts, but if I need to actually grab this integer value for something else, do you have any idea how I can grab/echo out just the value? Thanks!

You could store the length like this.

function store_excerpt_length($length) {
    update_option( 'excerpt_length', $length );
    return $length;
add_filter( 'excerpt_length', 'store_excerpt_length', 1000 );

Then use the following code to get the length.

echo get_option( 'excerpt_length' );

    Nice thinking, that's probably about the only way to do it. I would just add to give your filter an arbitrarily high priority (ie add_filter( 'excerpt_length', 'store_excerpt_length', 1000 ); to make sure it checks after any other filters have operated. Nov 29, 2011 at 18:17
  • You have a point there @goldeapples. Will update my answer with the priority. Nov 29, 2011 at 18:21
  • Meh - isn't actually echoing anything out. I do have a function that is setting the excerpt: function of_excerpt_length($length) { return 40; } but I wouldn't think that would actually be effecting that. Thanks!

  • You sure? Its working fine on my end. Where have you placed the code and what priority have you assigned to your filter? Dec 2, 2011 at 3:33
  • The function that you are calling can also be modified in the following manner of_excerpt_length($length) { $length = 40; update_option( 'excerpt_length', $length ); return $length; } Dec 2, 2011 at 8:02
