The get_row_index() (https://www.advancedcustomfields.com/resources/get_row_index/) function outputs how many rows there are in i flexible content field. Is there a equivalent function for outputting the number of times a specific layout is used?

Actually, get_row_index() returns the index of the current row inside of the have_rows() loop and does not return the total number of rows.

The total number of rows can be gotten like this.

$number_of_rows = count(get_field('flex_field_name'));

Other than looping through all of the rows and getting the layout for each, there isn’t a way to count the number of each layout used. This can be done a bit easier by getting the actual value stored for the flex field which is an array of the layouts.

$layouts = get_post_meta($post_id, 'flex_field_name');

this will return something like

$layouts = array(
  'layout1',
  'layout2',
  'layout3',
  'layout1',
  'layout2',
  'layout3',
  'layout1',
  'layout2',
  'layout3'
);

You can then use array_count_values() to get the number of times each layout appears

$layout_counts = array_count_values($layouts);

this will result in another array that would look something like this

$layout_counts = array(
  'layout1' => 3,
  'layout2' => 3,
  'layout3' => 3
);
