Question

以某种方式我的codeigniter表单验证没有显示在登录页面上以下是我在视图中的登录页面

            <div class="full_w">
        <p>Food4U</p>
        <?php echo validation_errors(); ?>
            <?php echo form_open('staff/valid_login'); ?>
                <label for="city">Select City</label>
                <select name="city" class="text">
                    <option value="">Select City</option>
                    <?php echo $this->front_model->get_Fcities(); ?>
                </select>
                <label for="login">Username:</label>
                <input id="login" name="username" class="text" />
                <label for="pass">Password:</label>
                <input id="pass" name="password" type="password" class="text" />
                <div class="sep"></div>
                <button type="submit" class="ok">Login</button>
                <a class="button" href="">Change Password</a>
            <?php echo form_close(); ?>
            </form>
        </div>

以下是控制器中的函数

    function valid_login()
{
    $this->form_validation->set_rules('city','City','required|trim|xss_clean|callback_validate_credentials');
    $this->form_validation->set_rules('username','Username','required|trim|xss_clean|callback_validate_credentials');
    $this->form_validation->set_rules('password','Password','required|trim');
    if($this->form_validation->run())
    {
        $data = array(
                'username' =>$this->input->post('username'),
                'is_loggedin' => 1
                );
            $this->session->set_userdata($data);
            redirect('staff/member');
    }
    else 
    {
        $this->load->view("dashboard/login");
    }

 }

 function member()
 {   
    $row['content']=$this->load->view("dashboard/member",array(),true);
    $this->load->view("dashboard/template", $row);
 }

function validate_credentials() 
{
    if($this->staff_model->can_login())
    {
        return true;
    }
    else
    {
        $this->form_validation->set_message('validate_credentials','Incorrect Username or Password');
        return false;
    }
}

我的模特函数是

    function can_login()
{
    $this->db->where('DB_User_City',$this->input->post('city'));
    $this->db->where('DB_User_Login',$this->input->post('username'));
    $this->db->where('DB_User_Pass',$this->input->post('password'));

    $query= $this->db->get('frp_db_user');

    if($query->num_rows() == 1)
    {
        return true;
    }
    else 
    {
        return false;
    }
}

如果用户只需点击提交按钮，用户就会看到一条消息，如果用户提供的任何单个值不正确，那么用户还必须看到登录错误，以便用户可以提供正确的信息

Answer 1

您的代码似乎没问题。试试这个

if($this->form_validation->run() == FALSE)
{ 
    //redirect to your login form
}
else
{
    //redirect to dashboard
}

如果您遇到任何问题，请告诉我。

在您的视图中为您设置的每个字段验证打击其字段或其他位置写下这些代码来显示验证错误。

      <div class="full_w">
    <p>Food4U</p>
    <?php echo validation_errors(); ?>
        <?php echo form_open('staff/valid_login'); ?>
            <label for="city">Select City</label>
            <select name="city" class="text">
                <option value="">Select City</option>
                <?php echo $this->front_model->get_Fcities(); ?>
            </select>
            <br />
            <?=form_error('city')?>
            <br />
            <label for="login">Username:</label>
            <input id="login" name="username" class="text" />
            <br />
            <?=form_error('username')?>
            <br />
            <label for="pass">Password:</label>
            <input id="pass" name="password" type="password" class="text" />

            <br />
            <?=form_error('password')?>
            <br />

            <div class="sep"></div>
            <button type="submit" class="ok">Login</button>
            <a class="button" href="">Change Password</a>
        <?php echo form_close(); ?>
        </form>
    </div>
