Thanks for sharing your code.
I may be mistaken, but I believe that I can add a simplification to ituk’s post. If you just want the first item in the repeater, you can target it with the  array index without needing to reset the repeater field. So the following chunk of ituk’s code:
$repeater_field = $_POST['acf']['field_57bc841e7f973']; //repater parent key reset($repeater_field); //reset repeater array to the rist row $first_field = key($repeater_field); //get first key in the repeater array $my_text_field = $_POST['acf']['field_57bc841e7f973'][$first_field]['field_57bc8a5447d06']; //specific field
can be simplified to this:
$my_text_field = $_POST['acf']['field_57bc841e7f973']['field_57bc8a5447d06']; //specific field
NOTE: This only works for the 1st item! It seems that the first item uses the  array index but each repeater subfield that gets added gets a randomly generated array index. So instead of going to  for the second item it will be something like [58b641f67f3de], which is a randomly generated string that is probably generated from the server’s timestamp.
