使用代码点火器的表单验证中出错

Question

我在使用 Codeigniter 验证表单时遇到问题。下面是我在项目中使用的代码。

我已经遵循了我在Codeigniter用户指南中阅读的所有规则，但我不知道这个问题是什么;验证没有发生。

控制器(页.php(

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Page extends Front_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Page_model');
$this->load->helper(array('form', 'url'));
}
public function index()
{
$data['page_title'] = 'Doctors Feedback';
$data['base_url']= $this->uri->segment_array();

$this->load->library('form_validation');
$this->form_validation->set_rules('name', 'Name', 'required');
$this->form_validation->set_rules('qualification', 'Qualification', 'required');
$this->form_validation->set_rules('age', 'Age', 'required');
$this->form_validation->set_rules('date', 'Date', 'required');
$this->form_validation->set_rules('residential', 'Residential Address', 'required');
$this->form_validation->set_rules('clinic', 'Clinic Address', 'required');
$this->form_validation->set_rules('email', 'E-mail', 'required');
$this->form_validation->set_rules('mobile', 'Mobile Number', 'required');
$this->form_validation->set_rules('phone', 'Phone Number', 'required');
$this->form_validation->set_rules('comment', 'Comment', 'required');
if ($this->form_validation->run() == FALSE)
{
$this->view('doctors_form', $data);
}
}
}
?>

景观 (doctors_form.php(

Answer 1

首先，您应该将控制器名称重命名为 Page.php(首字母大写(。控制器代码应如下所示：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Page extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('Page_model');
$this->load->helper(array('form', 'url'));
$this->load->library('form_validation');
}
public function index()
{
if ($_POST) 
{
$this->form_validation->set_rules('name', 'Name', 'required');
$this->form_validation->set_rules('qualification', 'Qualification', 'required');
$this->form_validation->set_rules('age', 'Age', 'required');
$this->form_validation->set_rules('date', 'Date', 'required');
$this->form_validation->set_rules('residential', 'Residential Address', 'required');
$this->form_validation->set_rules('clinic', 'Clinic Address', 'required');
$this->form_validation->set_rules('email', 'E-mail', 'required');
$this->form_validation->set_rules('mobile', 'Mobile Number', 'required');
$this->form_validation->set_rules('phone', 'Phone Number', 'required');
$this->form_validation->set_rules('comment', 'Comment', 'required');
if ($this->form_validation->run() == FALSE)
{
$data['page_title']         = 'Doctors Feedback';
$data['base_url']           = $this->uri->segment_array();
$this->view('doctors_form', $data);
}
else
{
$name           = $this->input->post('name',TRUE);
$qualification  = $this->input->post('qualification',TRUE);
$age            = $this->input->post('age',TRUE);
$date           = $this->input->post('date',TRUE);
$residential    = $this->input->post('residential',TRUE);
$clinic         = $this->input->post('clinic',TRUE);
$email          = $this->input->post('email',TRUE);
$mobile         = $this->input->post('mobile',TRUE);
$phone          = $this->input->post('phone',TRUE);
$comment        = $this->input->post('comment',TRUE);
$data = array(
'name'          => $name , 
'qualification' => $qualification , 
'age'           => $age , 
'date'          => $date , 
'residential'   => $residential , 
'clinic'        => $clinic , 
'email'         => $email , 
'mobile'        => $mobile , 
'phone'         => $phone , 
'comment'       => $comment , 
);
// Further deal with model using this array
}
}
}

}

在您看来，您应该最好使用代码点火器表单打开和关闭标签而不是 HTML 。

<?php echo form_open('Controller_name/function_name'); ?>  // equivalent to <form action='url'>
<?php echo form_close(); ?>  // equivalent to </form>

在您的情况下，您不必在 form_open 标记中写入函数名称。只需编写控制器名称，因为默认情况下会加载索引函数。
