Validation

A wiki is for collaboration right. I suggest we extend the validation library here together so feel free to add your code too.

=================[size=4]Rule Reference[/size]======================== [size=3]CI_Validation[/size] [code] required No Returns FALSE if the form element is empty.
matches Yes Returns FALSE if the form element does not match the one in the parameter. matches[form_item] min_length Yes Returns FALSE if the form element is shorter then the parameter value. min_length[6] max_length Yes Returns FALSE if the form element is longer then the parameter value. max_length[12] exact_length Yes Returns FALSE if the form element is not exactly the parameter value. exact_length[8] alpha No Returns FALSE if the form element contains anything other than alphabetical characters.
alpha_numeric No Returns FALSE if the form element contains anything other than alpha-numeric characters.
alpha_dash No Returns FALSE if the form element contains anything other than alpha-numeric characters, underscores or dashes.
numeric No Returns FALSE if the form element contains anything other than numeric characters.
valid_email No Returns FALSE if the form element does not contain a valid email address.
