I would like to output the name and the degree in this format: John Doe, PhD

My code is as follows:

$degree = get_field( 'degree', $post->ID );
<h4 class="block-slider-faculty__slide__details__title"><?php the_title(); ?><?php echo implode(', ', $degree); ?></h4>

I got a "Warning: Implode(): invalid arguments passed in…" error.

I believe I need to put the $degree in an array? Please let me know how I can do that with the code above. Thank you for your help.

implode() is intended to take an array and convert it to a string. Unless the value of $degree is an array, you're going to get an error.

If $degree is already a string value, there's no need to implode() it.

I'm guessing here because you didn't include any information in your question about where the name comes from and if the "degree" field is simply the degree. So the following is based on an assumption that the_title() is the name and $degree simply contains the degree as a string (such as "PhD").

$degree = get_field( 'degree', $post->ID ); <h4 class="block-slider-faculty__slide__details__title"><?php the_title(); ?>, <?php echo $degree; ?></h4>

Of course, if there is a possibility that $degree is empty, you'd have to also account for that, so the following might be better in that regard:

$degree = get_field( 'degree', $post->ID ); $degree_output = ( $degree ) ? ", " . $degree : ''; <h4 class="block-slider-faculty__slide__details__title"><?php the_title(); echo $degree_output; ?></h4>

(Also note above, there's no need in the second example (nor your original) to close PHP and then reopen it right away.)
