How to validate many fields combined in Codeigniter?

Question

Is there a creative and easy way to check many form fields at once.

I have a form with generated fields on the fly, each has a unique id.

The thing is submittin

Answer 1

Try this:

$_POST['data_you_want_to_validate_together'] = $_POST['first_field'] . $_POST['second_field'];
$this->form_validation->set_rules('data_you_want_to_validate_together','Some Data', 'required|callback_some_function');

Now you can get the data via:

echo $this->input->post('data_you_want_to_validate_together');
