MakiMaki, that won't work. You can only use the isin operator to make one single comparison.
Scakk's suggestion makes the recommended approach. You can also combine them with the && operator:
Code:
if ($numeric == 318) && ($numeric == 312) { halt }
You can, however, use the $count():
Code:
if ($count($numeric,312,318)) { halt }
in place of the isin, but isin is not considered appropriate.
I made sure what I posted worked thank you Jethro
and do please tell us all on what is considered appropriate,
I believe the proper way would be.
raw 312:*: { halt }
raw 318:*: { halt }
Deans method works, as does mine.
