A wiki is for collaboration right. I suggest we extend the validation library here together so feel free to add your code too.
=================Rule Reference========================
CI_Validation
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.
valid_ip No Returns FALSE if the supplied IP is not valid.
MY_Validation
no_space No Returns FALSE if the supplied post contains spaces.
