Question

我的控制器Hello.php在这里

class Hello extends CI_Controller {

    public function __construct(){
      parent::__construct();
      $this->load->model('insert_model');
    }

    public function index(){
      $this->insert_model->insert();
      $data['message'] = 'Data Inserted Successfully';
    }

我的模型insert_model.php这里

class insert_model extends CI_Model{

     public function __construct()
     {
       $this->load->database(); 
     }

     public function insert(){
       $data=array(
        'user_name'=>$this->input->post('user_name'),
        'user_email'=>$this->input->post('user_email'),
        'user_password'=>$this->input->post('user_password'),
        'user_dob'=>$this->input->post('user_dob'),
        'user_gender'=>$this->input->post('user_gender'),
        'user_address'=>$this->input->post('user_address'),
        'user_contact'=>$this->input->post('user_contact')

       );

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

但问题是这个我的记录没有插入数据库中.. 请帮我.. 提前致谢

**in controller**
public function index(){
      $data=array(
        'user_name'=>$this->input->post('user_name'),
        'user_email'=>$this->input->post('user_email'),
        'user_password'=>$this->input->post('user_password'),
        'user_dob'=>$this->input->post('user_dob'),
        'user_gender'=>$this->input->post('user_gender'),
        'user_address'=>$this->input->post('user_address'),
        'user_contact'=>$this->input->post('user_contact')

       );
      $last_id = $this->insert_model->insert_data($data);
if($last_id)
      $data['message'] = 'Data Inserted Successfully';

**In model**

      public function insert(){
     $this->db->insert('user',$data);
     //check the query by
     echo $this->db->last_query();
     return $this->db->insert_id();  
 }

根据您的代码，代码中没有任何问题。但请确保您的数据库user表格中包含user_name，user_email .... user_contact

等列

'user_name'=>$this->input->post('user_name'),
'user_email'=>$this->input->post('user_email'),
'user_password'=>$this->input->post('user_password'),
'user_dob'=>$this->input->post('user_dob'),

数组键应始终引用表列名称

'column_name'=>value,

你做错了。看到你在控制器中调用插入模型，你可以从控制器中发送数据，但不能在模型中发送。所以没有后期数据进入模型。

    class Hello extends CI_Controller {

        public function __construct(){
          parent::__construct();
          $this->load->model('insert_model');
        }

        public function index(){
          $data=array(
            'user_name'=>$this->input->post('user_name'),
            'user_email'=>$this->input->post('user_email'),
            'user_password'=>$this->input->post('user_password'),
            'user_dob'=>$this->input->post('user_dob'),
            'user_gender'=>$this->input->post('user_gender'),
            'user_address'=>$this->input->post('user_address'),
            'user_contact'=>$this->input->post('user_contact')

           );
          $data['last_id'] = $this->insert_model->insert_data($data);
          $data['message'] = 'Data Inserted Successfully';
        }

    class insert_model extends CI_Model{

         public function __construct()
         { 
           parent::__construct();
           $this->load->database(); 
         }

         public function insert_data($data){
            $this->db->insert('user',$data); 
            return $this->db->insert_id(); 
         }
    }

如果能解决您的问题，请告诉我。

我的代码出现了问题，首先在hello / index中加载视图页面然后检查提交按钮的设置，例如

$submit = $this->input->post('submit');
if(isset($submit)){}

或者，如果您在同一方法上加载视图页面，则必须调用表单操作;

<form method="post" action="<?php echo base_url(); ?>hello/index" >

我已更新您的代码

<强> Controller.php这样

class Hello extends CI_Controller {
    public function __construct(){
      parent::__construct();
      $this->load->model('insert_model');
    }
    public function index(){
        $submit = $this->input->post('submit');
        if(isset($submit)){
                  $data=array(
                    'user_name'=>$this->input->post('user_name'),
                    'user_email'=>$this->input->post('user_email'),
                    'user_password'=>$this->input->post('user_password'),
                    'user_dob'=>$this->input->post('user_dob'),
                    'user_gender'=>$this->input->post('user_gender'),
                    'user_address'=>$this->input->post('user_address'),
                    'user_contact'=>$this->input->post('user_contact')

                   );
                $insert = $this->inser_model-> insert_data();
                if($insert) {
                  $data['message'] = 'Data Inserted Successfully';
                }
        }
        $this->load->view('your_page');
    }
}

<强> Model.php

class insert_model extends CI_Model{
    public function insert_data($data){
        return   $this->db->insert('user',$data); 
    }
}
