Display all custom meta field values from the database using ACF Repeater

I don’t think ACF has a built-in function to do what you want. You can use get_field to retrieve a value from any post, but it requires a post ID if you want the value from anything other than the current post.

So instead, we can query posts using WP_Query and pass the meta key of our custom field.

Here is an example.

$args = array(
    'post_type' => 'page', // Add your post type here
    'meta_key' => 'test_repeater' // Add your repeater name here
);

$the_query = new WP_Query($args);

if ($the_query->have_posts()):
    while ($the_query->have_posts()) : $the_query->the_post();
            if(have_rows('test_repeater')): // Add your repeater here
                while (have_rows('test_repeater')) : the_row(); // Add your repeater here
                    // display your sub fields
                    the_sub_field('sub_field_one');
                    the_sub_field('sub_field_two');
                endwhile;
            else :
                // no rows found
            endif;
    endwhile;
endif;

I added the above code to a page template, it will spit out the values of my test_repeater for any page that has those custom fields filled out.

Tested and works.
