Description
I have an instrument with some integer-like field names in REDCap ("0" / "1"), this caused a type error in
RedcapNotificationHandler
with "string
expected,int
given". After investigating a bit, REDCap correctly sends the field namesas strings but it turns out that PHP implicitly converts array keys to integers if they look like integers.Changelog
strval
in the regex matching where the field name is required to be a string._formatEnumFields
slightly less unreadable by using aforeach
instead ofarray_keys
/array_reduce
.
