Penanganan File Upload

1. Membuat default image

Cari gambar default yang akan digunakan sebagai gambar default jika admin tidak mengupload foto. Beri nama default.jpg. Buat folder upload/biro dan letakkan gambar pada folder tersebut.






2. Membuat Fitur Upload

Biro_model.php

Tambahkan function  _uploadImage() dan ubah function save() dan update() dengan melakukan sedikit perubahan

 <?php defined('BASEPATH') OR exit('No direct script access allowed');  
 class Biro_model extends CI_Model  
 {  
   private $_table = "biros";  
   public $biro_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, ["biro_id" => $id])->row();  
   }  
   public function save()  
   {  
     $post = $this->input->post();  
     $this->biro_id = uniqid();  
     $this->name = $post["name"];  
     $this->price = $post["price"];  
     $this->image = $this->_uploadImage();  
     $this->description = $post["description"];  
     return $this->db->insert($this->_table, $this);  
   }  
   public function update()  
   {  
     $post = $this->input->post();  
     $this->biro_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"];  
     return $this->db->update($this->_table, $this, array('biro_id' => $post['id']));  
   }  
   public function delete($id)  
   {  
     return $this->db->delete($this->_table, array("biro_id" => $id));  
   }  
   private function _uploadImage()  
   {  
     $config['upload_path']     = './upload/biro/';  
     $config['allowed_types']    = 'gif|jpg|png';  
     $config['file_name']      = $this->biro_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";  
   }  
 }  

Isi form baru dan isi bagian gambar dengan memilih gambar yang akan diupload

Maka gambar yang akan ditampilkan pada halaman list biro
