Let do it without return nor exception :
let run dbh q userid =
if check_permissions userid = Failed then (
StdPages.error q "Sorry, but you don't have permission to see this"
) else
let query = q#param "query" in
if query =~ /^\s*$/ then (
StdPages.error q "Please enter a query"
) else
let resource =
try find_resource dbh query
with
Not_found ->
StdPages.error q "That resource doesn't exist in the database"
in
(* Do lots and lots of real processing here. *)
StdPages.ok q "OK, your query was executed"
I don't see what is your problem here...
