Question

我使用活动记录来更新我的数据库中的数据及其在数据库中的更新，但是在更新数据库内的数据后，我希望它重定向回我的编辑页面，显示来自我的数据库的更新数据..但是我试过不行。

我的codeigniter版本是2.7

＆＃13;

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class account extends CI_Controller {
function __construct()
	{
	parent::__construct();
		
		}
	
public function index(){
	
	$username = $this->input->post('username');
	$password = $this->input->post('password');
	$result = $this->login_model->database($username, $password);
	if ($result == TRUE){
	$data['posts'] = $result;
	$data['subview'] = 'testview';
		$this->load->view('display', $data);
	}else{
	echo "invalid password";
	};
}

public function edit(){
    $id = $this->input->post('id');
    $name = $this->input->post('name');
    $email = $this->input->post('email');
    $telephone = $this->input->po

<!-- begin snippet: js hide: false console: true babel: false -->

＆＃13;

ST（＆＃39;电话＆＃39）; $ result = $ this-＆gt; login_model-＆gt; update（$ id，$ name，$ email，$ telephone）;

    $data['posts'] = $result;
    $data['message'] =   "Record Updated Successfully."; // Print this Message in your edit view page as echo $message.
        $data['subview'] = 'testview';
        $this->load->view('display', $data);
    }

}

  <!--THIS IS MY MODEL-->

＆＃13;

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class login_model extends CI_Model {
function __construct()
	{
	parent::__construct();
		
		}
	
	public function database($username, $password)
	{	
		$this->db->select('*');
		$this->db->from('user');
		$this->db->where('username', $username);
		$this->db->where('password', $password);
		$this->db->limit(1);
		$query = $this->db->get();
		if($query->num_rows() ==1){
			return $query->result();
			}else{
			return false;
			}
	}
	
	public function update($id){
	$data = array(
               'id' => $this->input->post('id'),
               'name' => $this->input->post('name'),
               'email' => $this->input->post('email'),
               'telephone' => $this->input->post('telephone'),
            );

$this->db->where('id', $id);
$this->db->update('user', $data); 
}

}

Answer 1

Please update your model's update fuction like the following code.

public function update()
{
    $id =   $this->input->post('id');
    $name   =   $this->input->post('name');
    $email  =   $this->input->post('email');
    $telephone  =   $this->input->post('telephone');

    $data = array(
               'name' => $name,
               'email' => $email,
               'telephone' => $telephone,
            );
    $this->db->where('id', $id);
    $this->db->update('user', $data); 
}

Create a new function in your model for fetch the record with same updated id like the following

public function view($id)
{
        $this->db->where('id', $id);
        $result =   $this->db->get('user');
        return $result->result();
}


Please update your controller's edit Function like the following

public function edit(){

    $id =   $this->input->post('id');
    $result = $this->login_model->update();

    if ($result)
    {
       $resultData  =   $htis->login_model->view($id);//Calling the newly create model function for tething the record.
       $data_arr['id']  =   $id;
       $data_arr['name']    =   $resultData[0]->name;
       $data_arr['email']   =   $resultData[0]->email;
       $data_arr['telephone']   =   $resultData[0]->telephone;
       $this->load->view('edit', $data_arr);//Loading the edit view
    }
}


Assume, your edit view is as follows, just I am creating a view with neccessary fiels only

View Name:  edit.php //Saved in to view folder.

<form method="post" action="<?php echo site_url('account/edit');?>"> <!--account is the controller and edit is the controller's function-->
<input type="text" name="id" value="<?php if(isset($id)){ php echo $id;}?>">
<input type="text" name="name" value="<?php if(isset($name)){ php echo $name;}?>">
<input type="text" name="email" value="<?php if(isset($email)){ php echo $email;}?>">
<input type="text" name="telephone" value="<?php if(isset($telephone)){ php echo $telephone;}?>">
<input type="submit" value="Edit" name="submit">
</form>

Codeigniter，我使用活动记录更新我的数据库中的数据，我希望它重定向回我的编辑页面显示更新的数据
