If any body need – I found a solution for getting conditions of acf fields.
The fields groups and fields save in wp_post table, they have mark as ‘acf-field-group’ and ‘acf-field’ on post_type coluumn.
From ‘post_content’ column you can get array with field data (like name, type of field, placeholder, and etc), from group post type you can take a conditions of the fields group.
The data from filled ACF save to wp_postmeta table. All meta data save as two fields: one is related to wp_post table, another content saving data.
So for direct saving you can use update_meta() function.
let me know If you `ll need any help
