Membuat Crud CodeIgniter 3

Tutorial CodeIgniter Kali ini akan membuat proses Create, Read, Update, Delete atau bisa disingkat CRUD, disini saya akan membuatnya menggunakan codeigniter 3.

1. Membuat Database

masuk kedalam database daily_codeigniter kemudian masukan query sql dibawah ini untuk membuat tablenya :
CREATE TABLE `tb_biodata` (
  `id` int(255) NOT NULL,
  `name` varchar(255) NOT NULL,
  `gender` enum('Male','Female') NOT NULL,
  `birthday` date NOT NULL,
  `photo` varchar(255) NOT NULL,
  `hobby` varchar(255) NOT NULL,
  `about` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

--
-- Indexes for dumped tables
--

--
-- Indexes for table `tb_biodata`
--
ALTER TABLE `tb_biodata`
  ADD PRIMARY KEY (`id`);

--
-- AUTO_INCREMENT for table `tb_biodata`
--
ALTER TABLE `tb_biodata`
  MODIFY `id` int(255) NOT NULL AUTO_INCREMENT;

2. Membuat Controller

  • buat file controllers dengan nama Crud.php didalam folder app maka pathnya adalah application/controllers/app/Crud.php
  • kemudian isi dengan kode dibawah ini :
<?php  
defined('BASEPATH') OR exit('no direct script access allowed');

class Crud extends MY_App
{

    private $redirect = 'app/crud';

    public function __construct()
    {

        parent::__construct();

        $this->load->helper('form');
        $this->load->library('form_validation');
        $this->load->model('app/M_Crud');
    }

    public function index()
    {

        $data = [
        'title' => 'Module Crud',
        'biodata' => $this->M_Crud->read(),
        ];

        $this->load->view('app/crud/index',$data);
    }

    public function create()
    {

        $data = [
        'title' => 'Create Data',
        'update' => false,
        ];

        $this->load->view('app/crud/form',$data); 
    }

    public function process_create()
    {

        $create = $this->M_Crud->create();

        if ($create == TRUE) {

            $this->session->set_flashdata('create', true);
        }
        else {

            $this->session->set_flashdata('create', 'failed');
        }    

        redirect($this->redirect);
    }

    public function update($id)
    {

        $data = [
        'title' => 'Update Data',
        'update' => true,
        'biodata' => $this->M_Crud->read_by($id),
        ];

        $this->load->view('app/crud/form',$data);
    }

    public function process_update($id)
    {

        if ($this->M_Crud->update($id) == TRUE) {

            $this->session->set_flashdata('edit', true);
        }else {

            $this->session->set_flashdata('edit', 'failed');
        }     

        redirect($this->redirect);   
    }

    public function process_delete($id)
    {


        if ($this->M_Crud->delete($id) == TRUE) {

            $this->session->set_flashdata('delete', true);
        }else {

            $this->session->set_flashdata('delete', 'failed');
        }     

        redirect($this->redirect);
    }
}

?>

3. Membuat Model

  • Dilanjut membuat file model dengan nama M_Crud.php didalam folder app (buat folder app terlebih dahulu) maka pathnya adalah application/models/app/M_Crud.php
  • kemudian isi dengan kode dibawah ini :
<?php  
defined('BASEPATH') OR exit('no direct script access allowed');

class M_Crud extends CI_Model 
{

    private $table = 'tb_biodata';
    private $storage_path = 'storage/uploads/';


    /**
     * Form Process    
     */
    
    public function _form_data($identity = false)
    {

        $this->_form_validation();

        $prepare_data = array(
            'name' => $this->input->post('name'),
            'gender' => $this->input->post('gender'),
            'birthday' => date('Y-m-d', strtotime($this->input->post('birthday'))),
            'hobby' => $this->input->post('hobby'),
            'about' => $this->input->post('about'),
            );

        if (!empty($_FILES['photo']['name'])) 
        {

            if ($identity) 
            {

                $delete_image = $this->db->get_where($this->table,$identity)->row_array();

                $this->__delete_file($delete_image['photo']);
            }

            $upload_image = $this->__upload_file();

            if ($upload_image !== 'failed') 
            {

                $photo = $upload_image;
            }else 
            {

                echo "failed upload photo, code error";
                exit;
            }

            $photo = array('photo' => $photo);
            $data = array_merge($prepare_data,$photo);

        }else 
        {

            $data = $prepare_data;
        }

        return $data;
    } 

    public function _form_validation()
    {
        $this->form_validation->set_rules('name','name','required');
        $this->form_validation->set_rules('gender','gender','required');
        $this->form_validation->set_rules('birthday','birthday','required');        
        $this->form_validation->set_rules('hobby','hobby','required');
        $this->form_validation->set_rules('about','about','required');

        $this->form_validation->set_error_delimiters('<span>', '</span>');

        if($this->form_validation->run() != false)
        {

            return true;
        }else{

            $data = array(
              'name' => form_error('name'),
              'gender' => form_error('gender'),
              'birthday' => form_error('birthday'),
              'hobby' => form_error('hobby'),
              'about' => form_error('about'),
              );

            $this->session->set_flashdata($data);

            redirect($_SERVER['HTTP_REFERER']);
        }
    }


    /**
     * Database Process
     */

    public function read()
    {
        return $this->db->get($this->table)->result_array();

        $post_data = $this->_form_data();

        $this->db->insert($this->table,$post_data);

        return ($this->db->affected_rows() > 0) ? true : false;

    }

    public function update($id)
    {


        $identity = array('id' => $id);

            }else {                
                return true;

            $delete_image = $read->row_array();

            $this->__delete_file($delete_image['photo']);

            $this->db->delete($this->table,$identity);        

            return ($this->db->affected_rows() > 0) ? true : false;
        }

    }


    /**

    public function __upload_file()

            return 'success';
        }        
    }       

}

4. Membuat View

  • Buat folder crud didalam folder app (pathnya daily_codeigniter/application/views/app/crud)
  • Buat file index.php didalam folder app (pathnya daily_codeigniter/application/views/app/crud/index.php)
  • isi dengan kode ini
<?php $this->load->view('app/_layouts/header'); ?>
<?php $this->load->view('app/_layouts/sidebar'); ?>

<div class="row">
    <div class="col-md-12">

        <div class="c-card c-card--responsive h-100vh u-p-zero">
            <div class="c-card__header c-card__header--transparent o-line">
                <a class="c-btn--custom c-btn--small c-btn c-btn--info" href="<?php echo base_url('app/crud/create') ?>">
                    <i class="fa fa-plus"></i>
                </a>           
            </div>
            <div class="c-card__body">
                <?php $this->load->view('app/_layouts/alert'); ?>


                <div class="c-table-responsive">
