+Validating an Array (other than $_POST)
+=======================================
+
+Sometimes you may want to validate an array that does not originate from $_POST data.
+
+In this case, you can specify the array to be validated::
+
+ $data = array(
+ 'username' => 'johndoe',
+ 'password' => 'mypassword',
+ 'passconf' => 'mypassword'
+ );
+
+ $this->form_validation->set_data($data);
+
+Creating validation rules, running the validation and retrieving error messages works the same whether you are
+validating $_POST data or an array.
+
+**Important Note:** If you want to validate more than one array during a single execution, then you should
+call the reset_validation() function before setting up rules and validating the new array.
+
+For more info please see the :ref:`function-reference` section below.
