Question

我尝试填写表格，但出现此错误。请有人告诉我为什么？
我已经附上了所有代码和图像：我想要的是当我填写此表单时，它将自动保存在数据库中。而且，如果您能为我提供在phpmyadmin上如何将图像从相同的表单上传到相同的数据库。

错误消息：

这是模型：

 class Clinic_Model extends CI_Model 
 {
  function insert_into_db()
    {
    $pfn = $_POST['pfn'];
    $pe = $_POST['pe'];
    $pmn = $_POST['pmn'];
    $pa = $_POST['pa'];
    $pw = $_POST['pw'];
    $ph = $_POST['ph'];
    $pgt = $_POST['pgt'];
    $pbp = $_POST['pbp'];
    $pec = $_POST['pec'];

    $this->db->query("INSERT INTO add_clinic 
    VALUES($pfn','$pe','$pmn','$pa','$pw','$ph','$pgt','$pbp','$pec')");

}
}

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

这是控制器

class Easyclinic extends CI_Controller {

   //----------Constructor----------
  public function __construct()
    {
    parent::__construct();
    $this->load->helper('url');
    //load Model
    $this->load->model('clinic_model');

   }
  //----------BaseFunctions----------
   public function index()
    {    
    $this->load->view('add_patient');
    }
    public function mydata()
    {
    $this->load->view('mydata');
   }
   public function addpatient()
   {
    $this->load->view('add_patient');
   }    

     //---------Advinced Functions---------

    public function insert_into_db()
    {
    $this->load->model('clinic_model');
    $this->clinic_model->insert_into_db();
    $this->load->view('success');//loading success view
   }



     }

这是视图

Answer 1

在INSERT语句（VALUES($pfn'）的列中缺少'的小错误，但同时也存在将列匹配的问题。通常，我也会列出我要插入的列，例如...

$this->db->query("INSERT INTO add_clinic (`Patient Full Name`, *** )
    VALUES('$pfn','$pe','$pmn','$pa','$pw','$ph','$pgt','$pbp','$pec')");

（其中***只是要插入的列的列表）。

我要提出两个建议-首先是更改列的名称。列名中包含空格会导致各种问题，通常不建议这样做。

第二，要研究使用准备好的语句和绑定变量，这将在以后提供各种好处，包括安全性以及文本中某些字符没有问题。
