Simply do not include 'required' in your rule to allow an empty value. If empty, no further validations will be executed.

Hi,
Thanks.
I did not put required in rule.
If the field is empty, there is no error message.
If the field has non empty AND has A or B or C or D there is no error message.
If the filed has non empty and other than A OR B or C or D, there is error message.
I want to check other than empty , A, C ,D values.
Code:
$this->form_validation->set_rules('mark','mark','matches[ABCD]');how can I allow epmty value in matches[] rule in validation? - El Forum - 04-09-2010

Me confused.
First, you said you wanted to accept Empty, A, B, C and D as valid. Which is what your rule does. Now you state that you want to do the opposite, ie empty, A, B, C and D means error, all other values are fine?
