I have two fields in which the subtraction of the least field1 field2 must be equal to (0) zero. How do I not let add to the database if the total is greater than zero.
example:
if

field1 - field2 = 0

return true

if

field1 - field2 <> 0

return false
C
 		cgphp 11/3/2013
if(abs($values['field1'] - $values['field2']) > 0)

{

$message = 'Difference must be 0';

return false;

}


Replace field1 and field2 with the real names of the fields.
