looping nested repeaters

Hi, I am trying to loop thru two nested repeaters to get the total number of items they contain. I am getting int(0) NULL or string(1) “0”.

ACF:
-collections (repeater)
–name
–banners (repeater)
—banner_type

In the front end I do have 2 collections with 3 items each.
in the previous page/parent I wanna output 6 items.

I m trying to do it like that but with no success.

$number_of_banners = 0;
$collections = get_field(‘collections’);

foreach( $collections as $collection) {
$banners = get_sub_field(‘banners’);
$number_of_banners = $number_of_banners + $banners.count();
};

var_dump($number_of_banners);

Thanks for any help.

the first problem I see is that you are trying to use get_sub_field() outside of a have_rows() loop.

correct loop using have_rows()

if (have_rows('collections')) {
  while (have_rows('collections')) {
    the_row();
    $banners = get_sub_field('banners');
  }
}

correct loop using array

$collections = get_field('collections');
foreach ($collections as $collection) {
  $banners = $collection['banners'];
}

The other thing is this $banners.count(); should be count($banners)

Thank you John,
I solved it using the loop have rows:

$number_of_banners = 0;
if( have_rows('collections') ):
	while ( have_rows('collections') ) : the_row();
		if( have_rows('banners') ):
			while ( have_rows('banners') ) : the_row();
				$number_of_banners +=1;
			endwhile;
		endif;
	endwhile;
endif;

<p><?= $number_of_banners === 1 ? $number_of_banners . " banner" : $number_of_banners . " banners" ?></p>

I tried with the correct loop using array and it return 5 instead of 8 which is the number of only 1 banner repeater.
This is solved, however I would like to improve it using the loop array.
