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); ?>
