Modify excerpt length & more tag – WordPress

In WordPress, it have ability to display automatically fetched excerpt for search result, index & archive pages. But in default, the excerpt length is limited with in 55 words.

If we like to modify this excerpt length, we can easily achieve this by adding a simple function & filter in our child theme’s function.php file.

// Changing excerpt length
function new_excerpt_length($length) {
return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');

From now, our excerpt length will be 100 words.

Modify more tag

At the end of each excerpt, WordPress display some more tag like [...] etc. We can also modify this more tag by another simple function & filter.

// Changing excerpt more
function new_excerpt_more($more) {
return '<span class="continue-reading"> <a href="' . get_permalink() . '">Continue Reading »</a></span>';
}
add_filter('excerpt_more', 'new_excerpt_more');

We just want to copy & paste above code in to our child theme’s function.php file. Try this code & view the changes.
