This is how to pass custom error messages for CI3

For Grocery CRUD:

$crud = new Grocery_Crud();
$crud->set_table('customers');

$crud->columns('customerName','phone','addressLine1','creditLimit');
$crud->set_rules('customerName', 'Customer Name', 'rule1|rule2|rule3',
        array('rule2' => 'Error Message on rule2 for this field_name')
);

$output = $crud->render();
 
$this->_example_output($output);

In PHP tested in (4, 5.3, 7.*), a function will ignore any extra argument that it expects, so it should be backward compatible.
