does acf_save_post cause endless loop?

Question

I am using Advanced custom fields acf_save_post hook in one of my functions. In that function I use the add_post_meta function. Does this call acf_save_post again and cause an endless loop?

Answer 1

add_post_meta doesn't call the same hook again but there are some other functions such as wp_update_post which call the hook again. In case it is going into infinite loop you'll have to call remove_action inside the function to not make it recursive
