Rather than use wp_trim_words()
, you could use PHP’s substr()
like this:
function project_excerpt() {
global $post;
$text = get_field('project_description');
if ( '' != $text ) {
$text = strip_shortcodes( $text );
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>>', $text);
$text_length = strlen($text); // Get text length (characters)
$excerpt_length = 50; // 50 desired characters
$excerpt_more = '...';
// Shorten the text
$text = substr($text, 0, $excerpt_length);
// If the text is more than 50 characters, append $excerpt_more
if ($text_length > $excerpt_length) {
$text .= $excerpt_more;
}
}
return apply_filters('the_excerpt', $text);
}
