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.
