Question

控制器代码我有：

<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
card_view:cardCornerRadius="4dp">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="160dp"
    android:orientation="vertical"
    android:weightSum="4">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center_horizontal">

        <ImageView
            android:id="@+id/thumbnail"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:scaleType="centerCrop"
            />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="left|bottom"
            android:background="@android:drawable/screen_background_dark_transparent"
            android:orientation="vertical">

            <TextView
                android:id="@+id/title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:padding="16dp"
                android:textSize="16dp"
                android:textColor="#FFFFFF"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/count"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@id/title"
                android:paddingBottom="@dimen/songs_count_padding_bottom"
                android:visibility="invisible"
                android:paddingLeft="@dimen/album_title_padding"
                android:paddingRight="@dimen/album_title_padding"
                android:textSize="@dimen/songs_count" />
        </LinearLayout>
    </FrameLayout>
</LinearLayout>

模型代码我有：

    <?php
    class Latest_ctrl extends Ci_controller{


        public function insert(){

            $name=$this->input->post('name');
            $pass=$this->input->post('pass');
            $email=$this->input->post('email');
            $mobile=$this->input->post('mobile');
            $address=$this->input->post('address');
            $data=array(
                'name'=>$name,
                'pass'=>$pass,
                'email'=>$email,
                'mobile'=>$mobile,
                'address'=>$address
                );
            $this->load->model('latest_model');
             $query= $this->db->insert('form',$data);
             if($query){
                redirect('latest_ctrl/view');
             }
                }

        public function view(){
             $this->load->model('latest_model');
             $val=$this->latest_model->get_data();
              $data['value']=$val;
              $this->load->view('latest',$data);
        }
        public function index(){
    $this->load->view('new_login');
        }

        public function delete($id){
         $id=$this->uri->segment(3);
         $this->load->model('latest_model');
          $this->latest_model->delete_id($id);
          redirect(base_url('latest_ctrl/view'));

        }

        Public function update($id){
            $upd=$this->uri->segment(3);
            $data = array(
            'name' => $this->input->post('name'),
            'pass' => $this->input->post('pass'),
            'email' => $this->input->post('email'),
            'mobile' => $this->input->post('mobile'),
            'address' => $this->input->post('address')
            );
          $this->load->model('latest_model');

        }
    }
    ?>

查看我：

<?php
class Latest_model extends CI_model{


 public function insert($tableName,$data){
       return $this->db->insert($tableName, $data);
    }

    public function get_data(){
        $query = $this->db->get('form');
        if ( $query->num_rows() > 0 )
        {
        $row=$query->result();
        return $row;
        }
    }

    public function delete_id($id){
        $this->db->where('id', $id);
        $this->db->delete('form'); 
    }


public function update_data(){

}
}


?>

我想为此目的编辑特定记录，我需要模型和控制器代码来更新codeigniter中的记录。

此外，我有一个页面将页面重定向到更新控制器，但我只想更新模型和控制器的代码以进行更新。

**Controller**

- ＆GT;在此处添加构造和加载模型，以便您无法在每个函数中加载模型

<?php
class Latest_ctrl extends CI_controller{

  function __construct()
  {
    parent::__construct();

    $this->load->model('latest_model');      


}

    public function insert()
    {

        $name=$this->input->post('name');
        $pass=$this->input->post('pass');
        $email=$this->input->post('email');
        $mobile=$this->input->post('mobile');
        $address=$this->input->post('address');
        $data=array(
          'name'=>$name,
          'pass'=>$pass,
          'email'=>$email,
          'mobile'=>$mobile,
          'address'=>$address
          );

        $id = $this->latest_model->insert($tableName="form",$data);

        if($id)
        {
            redirect('latest_ctrl/view');
        }
    }

    public function view()
    {

        $val=$this->latest_model->get_data();
        $data['value']=$val;
        $this->load->view('latest',$data);
    }

    public function index(){
        $this->load->view('new_login');
    }

    public function delete($id)
    {
        $id=$this->uri->segment(3);

        $this->latest_model->delete_id($id);
        redirect(base_url('latest_ctrl/view'));

    }

    Public function update($id)
    {
        $id=$this->uri->segment(3);
        $data = array(
            'name' => $this->input->post('name'),
            'pass' => $this->input->post('pass'),
            'email' => $this->input->post('email'),
            'mobile' => $this->input->post('mobile'),
            'address' => $this->input->post('address')
        );

    $this->latest_model->update_data($tableName="form",$data,$id);
    }
}
?>

型号代码

<?php
   class Latest_model extends CI_model{


    public function insert($tableName,$data)
    {
        $this->db->insert($tableName, $data);
        return $this->db->insert('form',$data);
    }

    public function get_data()
    {
        $query = $this->db->get('form');
        if ( $query->num_rows() > 0 )
        {
        $row=$query->result();
        return $row;
        }
    }

    public function delete_id($id)
    {
        $this->db->where('id', $id);
        $this->db->delete('form'); 
    }


    public function update_data($tableName,$data,$id)
    {
        $this->db->where('id'=>$id)
        $this->db->update($tableName, $data);
        return true;
    }
}
?>

需要我的程序的更新代码
