+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.
+
+For more info please see the :ref:`function-reference` section below.
