CodeIgniter把0而不是字符串值到數據庫

Question

我想用CodeIgniter建立一個小博客，出於某種原因，我把表單數據庫條目0而不是字符串。我試圖手動通過控制器，它的工作原理。表單中有什麼問題？

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

類site_model延伸CI_Model {

var $title = ''; 
var $content = ''; 
var $date = ''; 

function __construct() 
{ 
    // Call the Model constructor 
    parent::__construct(); 

} 


function get_records() 
{ 
    $query = $this->db->get('posts'); 

    return $query->result(); 

} 


function add_records($data) { 

    $this->db->insert('posts', $data); 

    return; 


} 

function updata_records($data) { 

    $this->db->where('postID', $id); 
    $this->db->updata('posts', $data); 



} 

function delede_roe() { 

    $this->db->where('postID', $this->uri->segment(3)); 
    $this->db->delete('posts'); 



} 

}

/*文件結束的welcome.php / /位置：./application/controllers/welcome.php */

表格頁面：

<div class="grid_11"> 
      <h2>About</h2> 
     <?php echo form_open('site/creata'); ?> 

    <label for="title"> title </label> 

    <input type="text" name="title" id="title"> 

    <label for="content"> content </label> 

    <input type="text" name="content" id="content"> 

    <br> 

    <input type="submit" value="send"> 

    <?php echo form_close(); ?> 
     </div> 

的CONTROLER：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

類網站的擴展是CI_Controller {

/** 
* Index Page for this controller. 
* 
* Maps to the following URL 
*  http://example.com/index.php/welcome 
* - or - 
*  http://example.com/index.php/welcome/index 
* - or - 
* Since this controller is set as the default controller in 
* config/routes.php, it's displayed at http://example.com/ 
* 
* So any other public methods not prefixed with an underscore will 
* map to /index.php/welcome/<method_name> 
* @see http://codeigniter.com/user_guide/general/urls.html 
*/ 
public function index() 
{ 
    $this->load->view('home'); 
} 

function add_post() { 

    $this->load->view('add_post'); 


} 



    function creata() { 


     $data = array (
      'title' => $this->input->post('title'), 
      'post' => $this->input->post('content') 

    ); 

    $this->load->model('site_model'); 
    $this->site_model->add_records($data); 



} 

}

/*文件結束的welcome.php / /地點：./application/ controllers/welcome.php */

Answer 1

您的控制器功能應該如下所示：

function creata() { 
    if($this->input->post(null)){ //enter if the form is submitted 
     $data = $this->input->post(null, true); // get all the data of the post 
     print_r($data);die; // see the post data 
     $this->load->model('site_model'); 
     $this->site_model->add_records($data); 
     $this->session->set_flashdata('msg', 'A msg to show to the user about the insertion'); 
     redirect('site/creata', 'refresh'); 
    }else{ //load the form 
     $this->load->view('home'); 
    } 
} 

您窗體對我來說看起來不錯。您的模型可能包含一個額外的行來查看查詢。

function add_records($data) { 
    $this->db->insert('posts', $data); 
    $this->db->last_query(); die; //check the query it's executing. 
    return; 
}
