如何修复使用实体类时未找到的类？ 如何在对象中显示数据库？

Question

I was trying a tutorial from another place to show my data from an instance object. But when i try to implement it, i found error Message: Class 'Booking' not found Filename: C:\xampp\htdocs\teja\application\controllers\controlBooking.php

this is my code in class Booking

<?php namespace application\classes;
class Booking {
    protected $id;
    protected $name;
    protected $address;
public function setId(string $id){
    $this->id = $id;
}
public function getId(){
    return $this->id;
}
public function get_booking()
{
    $query = $this->db->select("*")
             ->from('booking')
             ->order_by('id', 'DESC')
             ->get();
    return $query->result();
}...

And this is my model class

<?php use application\classes\Booking;
class modelBooking extends CI_Model{
    public function get_all(){
        $book = new Booking();
        $testimoni->get_booking();
    }
}

and this is my controller

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class controlBooking extends CI_Controller {
public function __construct(){
    parent ::__construct();
    //load model
    $this->load->model('modelBooking'); 
}
public function index(){
    $data = new Booking();
    $this->load->view('viewBooking', $data);
}

then how i show it in my view class? how to fix that error? thankyou for all of you, please help me to solve this

Answer 1

First, the file Booking.php should be moved to the folder /application/libraries/

Then, instead of using new, use the standard CodeIgniter library loading scheme, e.g.

$this->load->library('booking');

The CodeIgniter 'Loader' (ie. $this->load->...) will locate the class file (if it is in the right place), include it, and instantiate the named class.

Wherever you want to use the instance created by the above use

$this->booking->some_method();
