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。
我遵循了cdoeigniter用户指南中已阅读的所有规则，但是不知道是什么问题，验证没有发生。
控制器（page.php）
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);
}
}
}
?>
view(doctors_form.php)

答案 0 :(得分：0)
首先，您应该将控制器名称重命名为Page.php（首字母大写）。您的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
}
}
}
}
您认为，最好使用codeigniter形式的open和close标签代替HTML。
<?php echo form_open('Controller_name/function_name'); ?> // equivalent to <form action='url'>
<?php echo form_close(); ?> // equivalent to </form>
就您而言，您不必在form_open标记中编写函数名称。只需写控制器名称，因为默认情况下会加载索引函数。
