Using PHP in Excerpts+ Meta fields

Excerpts+ v2.2 introduced a very useful ability to allow PHP code in the Meta fields.

For example, let’s say you’ve got your Excerpts+ leaf setup the way you want but you also want to display the most recent comment for each post. You simply insert the code intio the meta field, making sure it is enclosed in the <?php ?> pair, as shown in the image below.


The setup


The code is:

$comments = get_comments(‘post_id=’.get_the_ID().’&order=DESC&status=approve’);
if ($comments) {
echo ‘<strong>Latest comment:<br/>’.$comments[0]->comment_author.’ said: </strong>’;
echo ‘<em>’.substr($comments[0]->comment_content,0,200).’…</em>’;


The result


Although this is a very brief tutorial, hopefully it will inspire you to think of other ways you might use this new facility.
