The official Kohana form Validation tutorial is a bit rough. I have been reading it for half a day. This tutorial is a serialization tutorial, data or the data structure (Kohana ORM) described above)
Step 1: write verification rules in application/model/article. php:

// Verification rule public function rules () {return array ('CID' => array ('not _ empty ')), 'title' => array ('not _ empty'),), 'content' => array ('not _ empty '), array ('min _ length', array (': value', 4), array ('max _ length', array (': value ', 40 )),),);}

Step 2: write the verification prompt information in application/messages/models/article. php (create a directory without it)

 */Return array ('CID' => array ('not _ empty' => 'Article category cannot be blank '), 'title' => array ('not _ empty' => 'Article title cannot be blank '), 'content' => array ('not _ empty' => 'Article content cannot be blank ', 'min _ length' =>' content must be at least 4 characters ', 'max _ length' => 'content cannot exceed 40 characters '));

Step 3: compile the foreground html file: application/views/welcome/index. php

            PHP dot-http://www.phpddt.com        
                            

Step 4: compile the Controller file application/controller/welcome. php:

 find_all();            $this->template->category = $category;            if($_POST)            {                $artile = ORM::factory('article')->values($_POST);                  $vali = Validation::factory($_POST, '_external', array());                try{                        $artile->save($vali);                }                 catch (ORM_Validation_Exception $e)                 {                    $this->template->errors = $e->errors('models');                }            }        }}

If the verification rule is not met, an error is prompted, such:
