I have a text area field on a custom post type called ‘news.’ In my template file, I’m pulling the title, the date, and some other data from the post and displaying it. The problem comes when I try to shorten the content of the post to a more manageable size. I could force a restriction in ACF when they input the text, but I need it all for the full post. Here’s what I’ve got right now:
<?php $args = array( 'posts_per_page' => 1, 'post_type' => 'news' ); // get results $the_query = new WP_Query( $args ); // The Loop ?> <div> <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?> <?php $url = get_field('external_link');?> <?php if( $url ): ?> <h4> <a href="<?php echo $url ?>"> <?php the_title(); ?> </a> </h4> <?php else: ?> <h4> <?php the_title(); ?> </h4> <?php endif; ?> <p style="font-size:14;font-weight:300;"> <?php $date = DateTime::createFromFormat('Ymd', get_field('date')); echo $date->format('m-d-Y'); ?>, <?php the_field('pub_name'); ?> </p><small> <?php $descr = the_field('description'); $descr = strip_tags($descr); echo substr($descr, 0, 135); // pull only x amount of characters from the content ?>… </small> <?php endwhile; ?> </div> <?php wp_reset_query(); // Restore global post data stomped by the_post(). ?>
The title is working, the date is working, and the pub_name is working. If I pull the ‘description’ field (starting with the $descr = the_field(‘description’) line), I cannot shorten it at all. The code above just outputs the entire thing, not the first 135 characters as I specified.
The only thing I could think of is that if I echo the data type of the $descr variable, it comes out as ‘NULL’. I converted it to a string as a test, and that didn’t do any good. I’ve been wrestling with this for a couple of hours now and for the life of me, I can’t get the description to come out shorter than the full length. I searched the forums and found someone else using substr() and saying that it worked… I’m out of ideas.
Thank you in advance
I kind of solved it:
<small> <?php $key_1_value = get_post_meta( get_the_ID(), 'description', true ); $key_1_value = strip_tags($key_1_value); echo substr($key_1_value, 0, 130); // pull only x amount of characters from the content ?>… </small>
If I use “get_post_meta”, it works just fine. The issue seems to be with using the_field() for some reason.
