Question

我的代码中有什么问题我似乎无法通过id显示我的数据库中的数据，当我进入此链接时http://localhost/server/index.php/api/example/users/id/1.xml它仍会显示我数据库中的所有数据

控制器的

         public function users_get()
{
    // Users from a data store e.g. database
    $users = 
    $result=$this->regusers->get();

    $id= $this->get('result');

    // If the id parameter doesn't exist return all the users

    if ($id === NULL)
    {
        // Check if the users data store contains users (in case the database result returns NULL)
        if ($users)
        {
            // Set the response and exit
            $this->response($users, REST_Controller::HTTP_OK); // OK (200) being the HTTP response code
        }
        else
        {
            // Set the response and exit
            $this->response([
                'status' => FALSE,
                'message' => 'No users were found'
            ], REST_Controller::HTTP_NOT_FOUND); // NOT_FOUND (404) being the HTTP response code
        }
    }

    // Find and return a single record for a particular user.

    $id = (int) $id;

    // Validate the id.
    if ($id <= 0)
    {
        // Invalid id, set the response and exit.
        $this->response(NULL, REST_Controller::HTTP_BAD_REQUEST); // BAD_REQUEST (400) being the HTTP response code
    }

    // Get the user from the array, using the id as key for retreival.
    // Usually a model is to be used for this.

    $user = NULL;

    if (!empty($users))
    {
        foreach ($users as $key => $value)
        {
            if (isset($value['result']) && $value['result'] === $id)
            {
                $user = $value;
            }
        }
    }

    if (!empty($user))
    {
        $this->set_response($user, REST_Controller::HTTP_OK); // OK (200) being the HTTP response code
    }
    else
    {
        $this->set_response([
            'status' => FALSE,
            'message' => 'User could not be found'
        ], REST_Controller::HTTP_NOT_FOUND); // NOT_FOUND (404) being the HTTP response code
    }
}

模型

<?php 

class Regusers Extends CI_Model{

public function get(){

    $query = $this->db->get('tbl_users');
    return $query->result();
   }
  }

我看不到你的班级名字，但是你可以这样做：将参数添加到公共函数中并使用url填充它。

网址：http://localhost/server/index.php/api/users_get/ID_HERE

另外，请尝试仅在模型中获取所需的记录。而不是自己循环所有记录。

控制器;

  public function users_get($id = null)
 {
 if($id === null){
 // GET ALL USERS

// Call here your model function to select all users

}else{
// GET USER WITH ID $id


// Call here your model function to select user by ID
}
}

模型;

// Get all users
public function get(){

$query = $this->db->get('tbl_users');
return $query->result();
}

// Get user based on ID
public function getById($id){

$query = $query = $this->db->get_where('tbl_users', array('id' => $id)
return $query->result();
}

Codeigniter Rest Api，什么是错的
