Important warning about variable hooks

Some hooks have variables in their names. For example, pre_${taxonomy}_$field and admin_head- both have variable names. In general, any hook that ends (or begins) with - or _, or contains a $, has a variable name. Since the syntax with which these variables are defined may change from version to version, this page may think that a hook is deprecated (or new) even if it is not. You can usually catch this sort of thing by comparing this hook to the list of "related hooks" below.
