Excerpt Field Length

Hi there,

may i ask why you want to do that when you could just type a shorter excerpt?

Only because they are job vacancy posts and as theres likely to be alot of them I'm not sure the client would want to check how many words they are writing everytime they publish a post.

I suppose you could re-purpose this function:

https://docs.generatepress.com/article/activating-read-custom-excerpt/#read-more-text

Something like this:

add_filter( 'wp_trim_excerpt', 'tu_excerpt_metabox_more' );
function tu_excerpt_metabox_more( $excerpt ) {
    $output = $excerpt;	

    if ( has_excerpt() ) {
        $output = sprintf( '%1$s <a href="%2$s">%3$s</a>',
            wp_trim_words( $excerpt, 15),
            get_permalink(),
            __( 'Read more', 'generatepress' )
        );
    }

    return $output;
}

This wp_trim_words( $excerpt, 15) is what sets the number of words to display
