Multiple excerpt lengths

Go to source

This snippet will allow you to set custom excerpt lengths in your excerpt tag in your template.

Instructions
Add this code to your functions.php file.

function excerpt($limit) {
      $excerpt = explode(' ', get_the_excerpt(), $limit);
      if (count($excerpt)>=$limit) {
        array_pop($excerpt);
        $excerpt = implode(" ",$excerpt).'...';
      } else {
        $excerpt = implode(" ",$excerpt);
      } 
      $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
      return $excerpt;
    }

    function content($limit) {
      $content = explode(' ', get_the_content(), $limit);
      if (count($content)>=$limit) {
        array_pop($content);
        $content = implode(" ",$content).'...';
      } else {
        $content = implode(" ",$content);
      } 
      $content = preg_replace('/\[.+\]/','', $content);
      $content = apply_filters('the_content', $content); 
      $content = str_replace(']]>', ']]>', $content);
      return $content;
    }

And then use this syntax to invoke your custom excerpt length in your template:

<?php echo excerpt(35); ?>
