WordPress | ACF | Repeater, display all sub-fields without specifically getting them

repeater_sub_all.php

<?php
if( have_rows('awards') ):
    while( have_rows('awards') ) : $row = the_row(); 
        $row = array_filter($row, 'strlen'); // filters out all the empty values
        echo implode(' - ', $row); // Displays all the values as a hyphen seperated list
    endwhile;
endif;

Show all ACF repeater sub-fields

I recently came up against a situation where my ACF repeater rows had six fields/keys each. This would've meant unnecessary and verbose code as I wanted to display all the values regardless.

My first challenge was to try and get all the contents from the_row(), however when I tried print_r(the_row()) it only displayed two rows and then stopped. Apparently my mistake here was using the_row() twice. To solve this I turned it into a variable using $row = the_row() ( thanks @elliotcondon ).

Now all I had to was implode and it worked... however it was including empty values, so I removed them using array_filter($row, 'strlen').

Job done. Useful to keep a record of this for future reference and in case anyone else comes up against it.
