I’m sure there must be a simple answer to this, but after working with this for several days I’m at a loss.

I’m trying to get field values from a custom post type which has custom fields. They are defined in a relationship field which itself is inside a repeater field.

(CPT) Program includes a Semester repeater.
(Repeater) Semester has fields which includes a Course Relationship field.
(CPT) Course has number and text fields.

Here’s the code I’m using:

<?php if( have_rows('semester') ): ?>

    <?php while( have_rows('semester') ): the_row(); ?>

        <h3><?php the_sub_field('year'); echo ' '; the_sub_field('term'); ?></h3>

        <?php 
        $course = get_sub_field('course');

        if( $course ): ?>
            <?php foreach( $course as $c ): // variable must NOT be called $post (IMPORTANT) ?>
                // works
					<h4><?php echo get_the_title( $c->ID ); ?></h4>
				// doesn't work
					<span class="dp-crs-title"><?php echo the_sub_field('course_title', $c->ID); ?></span>
                    <span><?php echo the_sub_field('credit_hours', $c->ID); ?></span>
            <?php endforeach; ?>

        <?php endif; ?>

    <?php endwhile; ?>

<?php endif; ?>
