WordPress: Function to Shorten Posts’ Titles

Sometimes you want to include a list of recent posts or posts in a category and you don’t want them to go onto a second line, so the only way to get around this is by shortening the title. This can be done using a handy little function that you put in your theme’s functions.php file.

Simply copy and paste the following into your functions.php file:

function short_title($after = '', $echo = true, $length = false) {
$title = get_the_title();
if ($length && is_numeric($length)) {
$title = substr( $title, 0, $length );
}
if (strlen($title)> 0) {
$title = apply_filters('short_title', $title . $after, $before, $after);
if ($echo)
echo $title;
else
return $title;
}
}

And to call this function within your theme, use the following code:

<?php short_title('...',true, '42'); // short_title('AfterText', 'true', 'WordLength') ?>
