在codeigniter中插入表单数据时出错

Question

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('company','Company 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'),
             'mobile_no' => $this->input->post('mobile'),
             'user_email' => $this->input->post('email'),
             'user_password' => $this->input->post('cpass'),
             'occupation' => $this->input->post('occupation'),
             'institute_name' => $this->input->post('institute'),

             'address' => $this->input->post('address1'),
             'city' => $this->input->post('city'),
             'pincode' => $this->input->post('pincode'));  

            // insert form data into database
            if ($this->Sign->insertUser($data))
            {

                $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{

    return false;

Answer 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。 ：）
