I want to prevent entire record data from being repeated in case it is repeated as it is.
for example if we have form has 3 fields and one user enter a record as below:
field_1 = 15
field_2 = 14
field_3 = 13
and he try to add a new record with same fields input
field_1 = 15
field_2 = 14
field_3 = 13
submit must be cancel
