Question

您好我曾试图查看其他人但是，无法根据他们的代码和解决方案找出我的工作原因。如果我禁用（注释掉）表单验证，我可以获得要显示的帖子数据。但如果留在它中总是出现错误，并且没有显示发布数据。我已经自动加载了我的模型，网址，表单，文本，安全性，form_validation

控制器中的

// Log in user
        public function login(){
            $data['title'] = 'Sign In';

            $this->load->helper(array('form', 'url'));

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


            // validate rules for login cedentials
            $this->form_validation->set_rules('username', 'Username', 'required');
            $this->form_validation->set_rules('password', 'Password', 'required');

            // if login credentials are not entered (validation is false) show login view
            if(!$this->form_validation->run()){
                $this->load->view('templates/header');
                $this->load->view('users/login', $data);
                $this->load->view('templates/footer');
                echo "Not valid!";
                echo "<br>";
                print_r($this->input->post());
                echo $this->input->post('username');
                echo validation_errors();
                echo $this->form_validation->run();


            } else { 

                // Get username
                $username = $this->input->post('username');
                // Get and encrypt the password
                $password = $this->input->post('password');

                // Login user with model (database)
                $user_id = $this->user_model->login($username, $password);

                if($user_id){
                    // Create session
                    $user_data = array(
                        'user_id' => $user_id,
                        'username' => $username,
                        'logged_in' => true
                    );

                    // set session user data
                    $this->session->set_userdata($user_data);

                    // Set message
                    $this->session->set_flashdata('user_loggedin', 'You are now logged in');

                    redirect('users/index');
                } else {
                    // Set message
                    $this->session->set_flashdata('login_failed', 'Login is invalid');

                    redirect('users/login');
                }       
            }
        } // end function login

以视图形式

<?php echo form_open('users/login'); ?> <!-- the action is the controller users and the function register -->
    <div class="row">
        <div class="col-md-4 col-md-offset-4">

            <div class="my-input-control-100p">
            <div class="form-group">
                <input type="text" name="username" class="form-control" placeholder="Enter Username" required autofocus>
            </div>
            </div>

            <div class="form-group">
                <input type="password" name="password" class="form-control" placeholder="Enter Password" required autofocus>
            </div>

            <button type="submit" class="btn btn-primary btn-block">Login</button>

            <br>

            <div class="center_login">
                <small><a href="<?php echo site_url("pages/view/register") ?>">Register here</a> </small>
                <br>
                <br>
                <small><a href="<?php echo site_url("pages/view/forgot") ?>">Forgot Password or User Name</a> </small>
            </div>
        </div>
    </div>
<?php echo form_close(); ?>

Answer 1

这是我使用它的唯一方法，因为它没有给出布尔值但布尔值的数字表示

if（$ this-＆gt; form_validation-＆gt; run（）！= 0）{

Answer 2

我也是第一次遇到这个问题。解决这个错误有两种方法：

第一种方法：

$attribute['method'] = 'post';

echo form_open('users/login',$attribute);

第二种方法：

form method="post" action="php start echo base_url('users/login') php end"

结论：- 你错过了形式的方法。

codeigniter表单验证总是错误的
