php - CodeIgniter form_validation 没有显示错误

Question

我是 CodeIgniter 的新手，我对 form_validation 有疑问:

• 我创建了一个 Controller 来进行身份验证，这是我的 Controller

============================================= ===========================

public function auth()
{
    $this->load->helper(array('from','url'));

    $this->load->library('form_validation');

    $rules = array(
        array(
            'field' => 'username',
            'label' => 'username',
            'rules' => 'required'
        ),
        array(
            'field' => 'password',
            'label' => 'Password',
            'rules' => 'required'
        )
    );
    $this->form_validation->set_rules($rules);

    if ($this->form_validation->run() == false) {
        $this->load->view('login');
    } else {
        echo ';) like a boss';
    }
    }
}

============================================= =================

• 我还创建了登录 View 。这是查看代码

============================================= =================

<section class="container">
    <div class="login">
        <h1>Login to Web App</h1>
        <?php
        $this->load->helper('form');
        echo validation_errors();
        echo form_open('login/auth');
        $username = form_input(array('name' => 'username', 'placeholder' => 'Username or Email'));
        $password = form_password(array('name' => 'password', 'placeholder' => 'Password'));
        $checkbox = form_checkbox('remember', '1');
        $submit = form_submit('submit', 'Login');
        ?>
        <p><?= $username ?></p>
        <p><?= $password ?></p>
        <p class="remember_me">
            <label>
                <?= $checkbox ?>
                Remember me on this computer
            </label>
        </p>
        <p class="submit"><?= $submit ?></p>
        <?php echo form_close(); ?>
    </div>
</section>

你的代码中多了一个尖括号

public function auth()
{
    $this->load->helper(array('from','url'));

    $this->load->library('form_validation');

    $rules = array(
        array(
            'field' => 'username',
            'label' => 'username',
            'rules' => 'required'
        ),
        array(
            'field' => 'password',
            'label' => 'Password',
            'rules' => 'required'
        )
    );
    $this->form_validation->set_rules($rules);

    if ($this->form_validation->run() == false) {
        $this->load->view('login');
    } else {
        echo ';) like a boss';
    }`enter code here`
}
