Posted 2021-05-04

function trim_words_shortcode( $atts, $content = '' ) {
   extract( shortcode_atts( array(
      'length' => '40',
      'after_url' => '',
      'after_text' => 'Read More'
      ), $atts ) ); 

   $link = "<a href='{$after_url}'>{$after_text}</a>";
   $append = " ...{$link}";
   return wp_trim_words( $content, $length, $append );
}
add_shortcode('trim_words', 'trim_words_shortcode');


/*
 * Usage:  [trim_words length="36" after_url="" after_text=""][types field="title"][/types][/trim_words]
 * Output:  It will take the data stored in whatever types field you are wrapping the shortcode around, truncate it down to X words you define, and use the URL and TEXT you pass in to append to the end after the hellips (...)
