无法在 codeigniter 中加载验证配置文件？

Question

我在 CodeIgniter 中创建了一个应用程序。我正在尝试在表单中插入验证。因为我的应用程序中有很多表单，所以我尝试使用验证配置文件来完成。

我在 application/config/form_validation.php 中创建了配置文件。我还通过添加 $autoload['config'] = array('form_validation');

自动加载了配置文件

不过，我的验证无法正常工作，它总是返回 boolean false

以下代码相同

form_validation.php 文件

<?php
$config= array(

    'Reservation' => array(
        array(
        'field' => 'name',
        'label' => 'Name',
        'rules' => 'required|max_length[50]|min_length[4]|trim|htmlspecialchars|alpha'
        ),
        array(
        'field' => 'date',
        'label' => 'Date',
        'rules' => 'required|trim|htmlspecialchars',
        'errors'=> ['required'=>'You must provide a %s for the reservation.']
        ),
        array(
        'field' => 'no_people',
        'label' => 'No of People',
        'rules' => 'required|trim|htmlspecialchars'
        )
    )

);
?>

index.php - 查看

<div class="book-reservation wow slideInUp" data-wow-duration="1s" data-wow-delay=".5s">
                    <?php echo "<script>alert('".validation_errors()."')</script>"; ?>
                    <?php echo form_open('Entry/Reservation'); ?>
                    <div class="col-md-12 form-left">
                        <label><i class="glyphicon glyphicon-calendar"></i>Enter Name:</label>
                        <input type="text" name='name' value="<?php echo set_value('name'); ?>">

                        </div>

            $this->session->set_flashdata('message','Your Reservation has accepted, We will call you back shortly.');
            redirect();
            }

            else
            {
            $this->session->set_flashdata('message','Some techincal issue occured, your reservation did not complete.');

            }
        }

Answer 1

以下代码出错，因为它没有重定向到任何地方

if($this->form_validation->run() == FALSE)
        {
            redirect();
        }

正确答案：

if($this->form_validation->run() == FALSE)
        {
            $this->load->view('index');
        }
