Your code works, but only for a text field, not for a repeater field.
I got it working for a repeater field using the code below:
`function my_acf_post_fields($post_id){
$post_id = get_the_id();
$post_author_id = get_post_field( ‘post_author’, $post_id );
if( have_rows(‘add_full_address’, ‘user_’ . get_post_field( ‘post_author’, $post_id )) ):
$i = 0;
while( have_rows(‘add_full_address’, ‘user_’ . get_post_field( ‘post_author’, $post_id )) ) : the_row();
$i++;
$value{$i} = get_sub_field(‘add_address_1’);
$value2{$i} = get_sub_field(‘add_address_2’);
$value3{$i} = get_sub_field(‘add_city’);
$value4{$i} = get_sub_field(‘add_zip_code’);

if( have_rows(‘c_address_of_your_clinics’) ) {
$i = 0;
while( have_rows(‘c_address_of_your_clinics’) ) {
the_row();
$i++; update_sub_field(‘c_address1’, $value{$i});
update_sub_field(‘c_address2’, $value2{$i});
update_sub_field(‘c_city’, $value3{$i});
update_sub_field(‘c_zipcode’, $value4{$i});
}
}
endwhile;
endif;
}
add_filter(‘acf/save_post’, ‘my_acf_post_fields’, 20);

However, it is not lopping through all the rows, it stops at the first row.
How do I make it look through and display all the row values.
Do I need to change the order of the if() and while() loops?
