Adding Custom Field to Custom Post Type Excerpt

I have a custom post type for staff members. On the about page I have a post grid that pulls those custom posts to show each staff member. For the design I need to be able to update the post excerpt using one of the custom field types I already have set up. The field type is a text field with the id “position”. Can anybody point me in the right direction? Found some other similar topics but they weren’t working.

Hi @avahidesign

I guess you can approach it in different ways.

If you’re looping through your CPT, you can simply echo out the custom field if it exists:

<?php
global $wp_query;
$paged = get_query_var('paged') ? get_query_var('paged') : 1;
$args = array(
	'posts_per_page' => 10,
	'post_type'		=> 'your-cpt',
	'paged' 		=> $paged
);
$wp_query = new WP_Query($args); ?>
<?php if ($wp_query->have_posts()) : ?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); 
$position = get_field('position');
?>

Your loop content
<?php 
if($position):
	echo $position;
endif;
?>

<?php endwhile;  ?> 
<?php endif; wp_reset_query(); ?>

Or you can add ACF fields to a custom excerpt:

// Custom Excerpt function for Advanced Custom Fields
function custom_field_excerpt() {
	global $post;
	$text = get_field('position'); //Replace 'your_field_name'
	if ( '' != $text ) {
		$text = strip_shortcodes( $text );
		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$excerpt_length = 20; // 20 words
		$excerpt_more = apply_filters('excerpt_more', ' ' . '[...]');
		$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
	}
	return apply_filters('the_excerpt', $text);
}

Then in your loop, display the custom excerpt:
echo custom_field_excerpt();
