如果需要改语言，则到

![70][]

并把语言包放到![70 1][]  
控制器代码:![70 2][]

public function verification()\{  
        $this->load->library('form\_validation');  
        $this->form\_validation->set\_rules('username', '用户名', 'required');  
        $this->form\_validation->set\_rules('password', '密码', 'required');  
        $this->form\_validation->set\_rules('passconf', '确认密码', 'required');  
        $this->form\_validation->set\_rules('email', '电子邮箱', 'required');  
        $bool = $this->form\_validation->run();  
        if($bool)\{  
            //数据库相关操作  
        \}else\{  
            $this->load->view('user/myform');  
        \}

视图代码![70 3][]

<html>  
<head>  
<meta charset="utf-8">  
<title>My Form</title>  
</head>  
<body>  
    <?php echo validation\_errors(); ?>  
    <?php echo form\_open('user/verification'); ?>  
    <h2>Username</h2>  
    <input type="text" name="username" value="<?php echo set\_value('username'); ?>" size="50" /><?php echo form\_error('username','<span>','</span>'); ?>  
    <h2>Password</h2>  
    <input type="text" name="password" value="<?php echo set\_value('password'); ?>" size="50" /><?php echo form\_error('password','<span>','</span>'); ?>  
    <h2>Password Confirm</h2>  
    <input type="text" name="passconf" value="<?php echo set\_value('passconf'); ?>" size="50" /><?php echo form\_error('passconf','<span>','</span>'); ?>  
    <h2>Email Address</h2>  
    <input type="text" name="email" value="<?php echo set\_value('email'); ?>" size="50" /><?php echo form\_error('email','<span>','</span>'); ?>  
    <div><input type="submit" value="Submit" /></div>  
    </form>  
</body>
