我已创建了一个注册表单，但每当我尝试将数据插入数据库时，它都不会给我错误，而是它与填充的数据保持在同一页面上。我在codeigniter中创建了这个.Below是我的代码。
控制器文件：Home.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form','url'));
$this->load->library(array('session','form_validation','email'));
$this->load->database();
$this->load->model('Sign');
}
public function index()
{
$this->load->view('home/index');
}
function signup()
{
$occu = $this->input->post('occupation');
$cf = $this->input->post('codefest');
$this->form_validation->set_rules('fname','Name','trim|required');
$this->form_validation->set_rules('mobile','Mobile No','trim|required');
$this->form_validation->set_rules('email','Email','trim|required|valid_email');
$this->form_validation->set_rules('password','Password','trim|required');
$this->form_validation->set_rules('cpass','Cofirm Password','trim|required|matches[password]');
$this->form_validation->set_rules('occupation','Occupation','trim|required|callback_select_validate');
$this->form_validation->set_rules('institute','Institute Name','trim|required');

$this->form_validation->set_rules('codefest','Codefest','trim|required|callback_select_codefest');
$this->form_validation->set_rules('address1','Address','trim|required');
$this->form_validation->set_rules('city','City','trim|required');
$this->form_validation->set_rules('pincode','Pincode','trim|required');
if ($this->form_validation->run() == FALSE)
{
// fails
$this->load->view('home/index');
}
else
{
//echo "inserted";
$data = array
('user_name' => $this->input->post('fname'),

{
$this->session->set_flashdata('msg','<div class="alert alert-success text-center">Your Message has been successfully received.We will back to you soon.</div>');
redirect('home/index');
}
else
{
// error
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('home/index');
}
}
}
// Below function is called for validating select option field.
function select_validate($occu)
{
if($occu=="none"){
$this->form_validation->set_message('select_validate', 'Please Select Your Occupation.');
return false;
} else{
// User picked something.
return true;
}
}
function select_codefest($cf)
{
if($cf=="none"){
$this->form_validation->set_message('select_codefest', 'Please Select a Codefest.');
return false;
} else{

return true;
}
}
}

答案 0 :(得分：1)
这些必填字段隐藏在表单中，因此验证失败;
<div class="form-group col-lg-10" id="student" style="display: none;">
<input type="text" class="form-control" name="institute" placeholder="Institute Name" value="<?php echo set_value('institute');?>">
<span class="text-danger"><?php echo form_error('institute'); ?></span>
</div>
<div class="form-group col-lg-10" id="professional" style="display: none;">
<input type="text" class="form-control" name="company" placeholder="Company Name" value="<?php echo set_value('company');?>">
<span class="text-danger"><?php echo form_error('company'); ?></span>
</div>
但验证在控制器中
$this->form_validation->set_rules('institute','Institute Name','trim|required');
$this->form_validation->set_rules('company','Company Name','trim|required');
如果不需要，请删除验证。 ：）
