Fixes a fatal error in
in_array
call when asupports
arg ofregister_post_type
is a booleanfalse
. The error was introduced in #62304. See also https://github.com/WordPress/gutenberg/pull/62304/files#r1853540430.I'm fixing this by calling
empty( ... )
instead ofisset( ... )
.empty
does the job of both checking that a variable is defined and also that it's notfalse
. Used also at other places for similar checks, guarding ain_array
call.FYI @TylerB24890.
