Hi al, Thanks for your reply, I managed to find a trick to solve this problem by using the native WordPress get_post_meta function, the idea is as follow:
$lists = get_field('lists', $post->ID);
$len= 0; // To get the number of rows
foreach ($lists as $key => $list) {
update_sub_field(array('lists', $key, 'field'), 0, $post->ID);
$len++;
}
$result = array();
for($i= 0; $i < $len; $i++) {
$result[$i]= array(
"field" => get_post_meta($post->ID, "lists_".$i."_field", true),
);
}
var_dump($result);
You have just to take a look about how ACF name the post meta fields here: http://www.advancedcustomfields.com/resources/querying-the-database-for-repeater-sub-field-values/
