PWEB C - CODE IGNITER

Untuk tugas kali ini, adalah menggunakan framework codeigniter dalam membuat web, saya mengikuti tutorial yang ada di www.petanikode.com

Untuk menambahkan fitur CRUD terlebih dahulu membuat database, dapat dibuat konfigurasi di config/database.php, kemudian ubah menjadi seperti ini

 $db['default'] = array(   
    'dsn'   => '',   
    'hostname' => 'localhost',   
    'username' => 'root',   
    'password' => '',   
    'database' => 'tokobuah',   
    'dbdriver' => 'mysqli',   
    'dbprefix' => '',   
    'pconnect' => FALSE,   
    'db_debug' => (ENVIRONMENT !== 'production'),   
    'cache_on' => FALSE,   
    'cachedir' => '',   
    'char_set' => 'utf8',   
    'dbcollat' => 'utf8_general_ci',   
    'swap_pre' => '',   
    'encrypt' => FALSE,   
    'compress' => FALSE,   
    'stricton' => FALSE,   
    'failover' => array(),   
    'save_queries' => TRUE   
  );

Lalu tambahkan database anda dan session di $autoload['libraries']

Kemudian untuk fitur CRUD, kita membuat agar admin dapat menambahkan produk-produk buah baru
Maka kita buat sebuah file untuk menampung produk tersebut di direktori : application/model/ yaitu file Product_model.php

 <?php defined('BASEPATH') OR exit('No direct script access allowed');   
  class Product_model extends CI_Model   
  {   
   private $_table = "products";   
   public $product_id;   
   public $name;   
   public $price;   
   public $image = "default.jpg";   
   public $description;   
   public function rules()   
   {   
    return [   
     ['field' => 'name',   
     'label' => 'Name',   
     'rules' => 'required'],   
     ['field' => 'price',   
     'label' => 'Price',   
     'rules' => 'numeric'],   
     ['field' => 'description',   
     'label' => 'Description',   
     'rules' => 'required']   
    ];   
   }   
   public function getAll()   
   {   
    return $this->db->get($this->_table)->result();   
   }   
   public function getById($id)   
   {   
    return $this->db->get_where($this->_table, ["product_id" => $id])->row();   
   }   
   public function save()   
   {   
    $post = $this->input->post();   
    $this->product_id = uniqid();   
    $this->name = $post["name"];   
    $this->price = $post["price"];   
    $this->image = $this->_uploadImage();   
    $this->description = $post["description"];   
    $this->db->insert($this->_table, $this);   
   }   
   public function update()   
   {   
    $post = $this->input->post();   
    $this->product_id = $post["id"];   
    $this->name = $post["name"];   
    $this->price = $post["price"];   
    if (!empty($_FILES["image"]["name"])) {   
     $this->image = $this->_uploadImage();   
    } else {   
     $this->image = $post["old_image"];   
    }   
    $this->description = $post["description"];   
    $this->db->update($this->_table, $this, array('product_id' => $post['id']));   
   }   
   public function delete($id)   
   {   
    $this->_deleteImage($id);   
    return $this->db->delete($this->_table, array("product_id" => $id));   
   }   
   private function _uploadImage()   
   {   
   $config['upload_path']   = './upload/product/';   
   $config['allowed_types']  = 'gif|jpg|png';   
   $config['file_name']   = $this->product_id;   
   $config['overwrite']   = true;   
   $config['max_size']    = 1024; // 1MB   
   // $config['max_width']   = 1024;   
   // $config['max_height']   = 768;   
   $this->load->library('upload', $config);   
   if ($this->upload->do_upload('image')) {   
    return $this->upload->data("file_name");   
   }   
   return "default.jpg";   
   }   
   private function _deleteImage($id)   
   {   
    $product = $this->getById($id);   
    if ($product->image != "default.jpg") {   
     $filename = explode(".", $product->image)[0];   
     return array_map('unlink', glob(FCPATH."upload/product/$filename.*"));   
    }   
   }   
  }

Kemudian untuk membuat produk-produk tersebut kita buat file bernama Products.php di direktori application/controllers/admin/

 <?php   
  defined('BASEPATH') OR exit('No direct script access allowed');   
  class Products extends CI_Controller   
  {   
   public function __construct()   
   {   
    parent::__construct();   
    $this->load->model("product_model");   
    $this->load->library('form_validation');   
   }   
   public function index()   
   {   
    $data["products"] = $this->product_model->getAll();   
    $this->load->view("admin/product/list", $data);   
   }   
   public function add()   
   {   
    $product = $this->product_model;   
    $validation = $this->form_validation;   
    $validation->set_rules($product->rules());   
    if ($validation->run()) {   
     $product->save();   
     $this->session->set_flashdata('success', 'Berhasil disimpan');   
    }   
    $this->load->view("admin/product/new_form");   
   }   
   public function edit($id = null)   
   {   
    if (!isset($id)) redirect('admin/products');   
    $product = $this->product_model;   
    $validation = $this->form_validation;   
    $validation->set_rules($product->rules());   
    if ($validation->run()) {   
     $product->update();   
     $this->session->set_flashdata('success', 'Berhasil disimpan');   
    }   
    $data["product"] = $product->getById($id);   
    if (!$data["product"]) show_404();   
    $this->load->view("admin/product/edit_form", $data);   
   }   
   public function delete($id=null)   
   {   
    if (!isset($id)) show_404();   
    if ($this->product_model->delete($id)) {   
     redirect(site_url('admin/products'));   
    }   
   }   
  }

Kemudian untuk fungsi CRUD untuk Produk Tokobuah maka kita buat list.php, new_form.php, dan edit_form.php di direktori view/admin

List.php
