How to add a custom excerpt length to Wordpress pages and posts?

Summary:

The WordPress excerpt is set by adding / modifying within the functions.php file.
However, what if i wanted a different excerpt length for different pages? You could create a series of IF/ELSE or Switch statements but this wouldn’t be the most efficient.

Solution:

Add the following to your functions.php within your template folder.

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;
}

Then you can use excerpt(80) in your template files.
Nice, simple and easy which will help you speed up development time.
