I have a form, and one input is amount. I want to be able to use 0 as a price, but if I use zero, I get an error as set by me that I cannot leave the input blank.
The field is set as int(10).
Thanks

Post your code for validating the field. You may want to use
!==''orisset()instead ofempty()orif($_POST[val])
