hi i have two fields and i need to output a error based on the fields data. something like the passwords that have to be equal but i don't need them to be eaqual but respect a custom relation. how can i resolve this using a callback function ? i need to call callback_myfunc($param1,param2) to be able to compare the two values. or any other method to do this ? thanks in advance for any response

Put the callback rule on the second field. The parameter to the callback function will be the content of that field. The other one you get using $this->input->post('fieldname'); Does that help?

yea i did like u said but would had been nice to have a special function for something like this. like if is used the same function in 3 rules the function to get the 3 values and so on
