%zonenum returns "invalid" data
|
I ran the following test:
| Code: |
$gzid = %zonenum( )
$bzid = %zonenum( "Non-existent Zone Name")
;;
#ECHO zoneid = $gzid
;;
#ECHO badzid = $bzid
;;
//Currently this is the way one must test for invalid zone names...
;;
#IF ($bzid = $gzid) {#ECHO This is an invalid Zone name.} {#ECHO This is a valid Zone name.}
|
As you can see, if the string passed to %zonenum does not represent an valid zone, the function will return the current zone number.
I believe this happens because, internally, CMUD interprets the NULL returned from the SQL query on ZoneTbl as if it were a NULL passed by the script (requesting the current zone number).
If this is the way it is supposed to work, please, update the documentation because this is not intuitively obvious since one would expect an error return of some kind if the zone did not exist (such as NULL, 0, or -1). |
