This is the code I am using to show html formatting on my wordpress post excerpts:
function get_excerpt($post, $ln){
if (!empty($post->post_excerpt)) {
if (strlen($post->post_excerpt) > $ln) {
echo mb_substr(($post->post_excerpt), 0, $ln);
}
} else {
if (strlen($post->post_content) > $ln) {
echo mb_substr(($post->post_content), 0, $ln);
}
}
}
How can I edit the mb_substr so that the excerpt will end at a period? For instance, an excerpt will end like this "she has a lovable and innocent charm tha" instead of "she has a lovable and innocent charm that keeps people caring about her." I want the excerpt to finish the sentence and end in a period instead of only stopping at the character limit, which is set at 800. In the code $ln is set to 800.
UPDATE:
This is the code I ended up using. Words are still cut off in the excerpt but I added a Read More link to the end with dots.
function get_excerpt($post, $ln){
if (!empty($post->post_excerpt)) {
if (strlen($post->post_excerpt) > $ln) {
echo mb_substr(($post->post_excerpt), 0, $ln) . '...'; ?> <a href="<?php echo get_permalink( $post -> ID )?>">[Read More]</a>
<?php }
} else {
if (strlen($post->post_content) > $ln) {
echo mb_substr(($post->post_content), 0, $ln) . '...';?> <a href="<?php echo get_permalink( $post -> ID )?>">[Read More]</a>
<?php }
}
}
