Multiple excerpt lengths in wordpress

Question

As it says in the title, I'm looking for multiple excerpt lengths in WordPress.

I understand you can do this in functions.php:

function twentyten_excerpt_length( $length ) {     return 15; } add_filter( 'excerpt_length', 'twentyten_excerpt_length' ); 

What I want to know is how you can have multiple of these each returning different numerical values so I can get short excerpts for sidebar loops, longer excerpts for featured loops, and the longest excerpt for the main article.

Something like using these in the templates:

<?php the_excerpt('length-short') ?> <?php the_excerpt('length-medium') ?> <?php the_excerpt('length-long') ?> 

Cheers, Dave

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); ?>

As for now, you can upgrade Marty's reply:

function excerpt($limit) {     return wp_trim_words(get_the_excerpt(), $limit); } 

You can also define custom 'read more' link this way:

function custom_read_more() {     return '... <a class="read-more" href="'.get_permalink(get_the_ID()).'">more&nbsp;&raquo;</a>'; } function excerpt($limit) {     return wp_trim_words(get_the_excerpt(), $limit, custom_read_more()); }
