the_excerpt Read More Filter

by

Just add the filter where you need it.

Define the filter callback in functions.php but don’t add the filter…

// Changing excerpt more
function new_excerpt_more($post) {
    return ' <a class="read_more" href="'. get_permalink($post->ID) . '">' . 'read more' . '</a>';
}

In your template file just before you need the custom more link:

add_filter('excerpt_more', 'new_excerpt_more');

And remove it afterwards

remove_filter('excerpt_more', 'new_excerpt_more');

Or make it self-removing…

function new_excerpt_more($post) {
    remove_filter('excerpt_more', 'new_excerpt_more'); 
    return ' <a class="read_more" href="'. get_permalink($post->ID) . '">' . 'read more' . '</a>';
}
