acf get_fields() does get the field names and values of repeaters and flex fields. For Example it returns this for a repeater
[repeater] => Array
(
[0] => Array
(
[field_1] => value 1
[field_2] => value 2
)
[1] => Array
(
[field_1] => value 1
[field_2] => value 2
)
)
Each sub array represents a row and the values are in field name => value pairs just like the top level fields.
A flex field is returned like this
[flex] => Array
(
[0] => Array
(
[acf_fc_layout] => layout_1
[field_1] => value 1
[field_2] => value 2
)
[1] => Array
(
[acf_fc_layout] => layout_2
[field_1] => value 1
[field_2] => value 2
)
)
again, of the values of the array is a row of the flex field.
maybe I’m missing what it is you’re really looking for. I think the real difficulty will be in telling the difference between flex fields, repeaters and other field types that store array values like select and checkbox fields.
