the_excerpt Read More Filter

Question

Currently, I call the_excerpt via traditional means:

<?php the_excerpt(); ?>

But I add a filter in functions.php for a custom "read more" message.

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

Here's the problem; I would like to call the_excerpt inside posts as well without any read more type of link being displayed while leaving the_exerpt being used in the actual excerpts unimpacted.

Answer 1

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>';
}
