Multiple Excerpt Lengths in Wordpress

Multiple excerpt lengths in wordpress

How about...

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;
}

then in your template code you just use..

<?php echo excerpt(25); ?>

Multiple Wordpress excerpt lengths on single page

See this question and answer. There's a function that let's you specify how the length of the excerpt on an ad-hoc basis.

Wordpress: How to obtain different excerpt lengths depending on a parameter

uhm, answering me again, the solution was actually quite trivial. it's not possible, as far as i know, to pass a parameter to the function my_excerpt_length() (unless you want to modify the core code of wordpress), but it is possible to use a global variable. so, you can add something like this to your functions.php file:

function my_excerpt_length() {
global $myExcerptLength;

if ($myExcerptLength) {
    return $myExcerptLength;
} else {
    return 80; //default value
    }
}
add_filter('excerpt_length', 'my_excerpt_length');

And then, before calling the excerpt within the loop, you specify a value for $myExcerptLength (don't forget to set it back to 0 if you want to have the default value for the rest of your posts):

<?php
    $myExcerptLength=35;
    echo get_the_excerpt();
    $myExcerptLength=0;
?>
