sedang dalam uji coba

image Upload adalah sebuah class helper dengan object oriented atau OOP yang menangani fitur image uploaded

support extention file pdf, png, jpeg, png, gif, svg, doc, docx, txt,

upload()

uploaded memiliki 3 paramter wajib, namafile, target directory, generate name files, dan akan result sebuah data object.

Upload("name_files_image", "directory", "generate_file_name");

value

  • "gambar" => name file dari name di html

  • $directory => target directory

  • false => file tidak di generate nama filesnya

  • true => false di generate random nama filesnya

nama "gambar nama file pada html input type files

pada berkas view html

 <form action="<?= url("gambar/upload") ?>" method="post" enctype="multipart/form-data">
   <input type="file" name="gambar"> 
   <button type="submit">save</button>
 </form>

pada berkas controller

<?php
# import class pada controller
use MiniMVC\System\Storage;

# buat object
$storage =  new Storage();

# target directory
$directory = "temp/;

# call functionnya
$data = $storage->Upload("gambar", $directory, false);

# result
var_dump($data);

result berupa object

object(stdClass)[57]
    public 'image_original_name' => string 'preview.jpg' (length=11)
    public 'image_name' => string '86e8985aa845f5a82b2b72e2b7bed713.jpg' (length=36)
    public 'image_type' => string 'image/jpeg' (length=10)
    public 'image_size' => int 1238922
    public 'image_error' => int 0

update files ()

untuk melakukan update files, files yang di update akan menghapus file lama dan mereplacenya dengan files baru mempunyai empat parameter

UpdateFile("file_lama", "file_baru", "directory", "generate_file_name");

pada berkas view html

 <form action="<?= url("gambar/update") ?>" method="post" enctype="multipart/form-data">
   <input type="file" name="gambar"> 
   <button type="submit">save</button>
 </form>

pada berkas controller

<?php
use MiniMVC\System\Storage;

# buat object
$storage =  new Storage();

# target directory
$directory = temp_dir();

# call functionnya
# $oldfiles = $directory . "namafilesnya";

#example 
$oldfiles = $directory . "deecbcc27b035a55cc5692326d24e09e.png";

$data = $storage->UpdateFile($oldfiles, "gambar", $directory, true);

# result object
var_dump($data);

# get nama files
echo $data->image_name; #or

# save nama files to variabel
$image = $data->image_name;

interacting image with database

untuk interacsi dengan data didatabase

# uploaded algorithm

# uploade image
# 1. uploaded files images
# 2. getting name files image
# 3. insert name files image to database


# update images
# 1. update files image
# 2. getting name files image
# 3. update name files image to database

Files Upload ( pdf , exel, doc )

sedang dalam uji coba

upload csv or excel

untuk upload files berformas csv atau excel dapat menggunakan libraries office yang dibuat yaitu read_file_csv(). untuk mengubah field pada csv menjadi array. setelah berubah menjadi array bisa di coba melakukan looping insert data. 

use MiniMvc\Apps\Libraries\office; // libraries

$office = new office;    // buat object baru
$office->read_file_csv("namefile"); // return object

example

arah routenya web.php

web.php

$router->get('office/upload', function () {
	Routes::Routing("officeController", "index");
});
$router->post('office/upload', function () {
	Routes::Routing("officeController", "upload");
});

office_view.php

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
    <form action="office/upload" method="post" enctype="multipart/form-data" >
        <input type="file" name="document" id="document">
        <button type="submit">import</button>
    </form> 
</body>
</html>

pada berkas controllernya

officeController.php

ini akan me return atau mengembalikan nilai array

use MiniMvc\Apps\Libraries\office;

class welcome extends Controller
{

	public function __construct()
	{
		// code here
	}

	public function index()
	{
		view("office_view");
	}

	public function upload()
	{
		$office = new office;
		$data = $office->read_file_csv("document"); // name di input html
		
		dump($data); // debug return object
	}

}

Multiple Insert

untuk multiple insert data, hasil membaca file dari file excel itu bisa dilakukan dengan looping

example hasil read file excel *covid-19 data example*,

index 0 atau pertama adalah nama column by row,

sebelum di remove index 0 atau nama columnnya :

^ array:15 [â–¼
  0 => array:6 [â–¼
    0 => null
    1 => "ODP"
    2 => "PDP"
    3 => "POSITIF"
    4 => "SEMBUH"
    5 => "MENINGGAL"
  ]
  1 => array:6 [â–¼
    0 => "3/26/2020"
    1 => 204
    2 => 89
    3 => 17
    4 => 0
    5 => 4
  ]
  2 => array:6 [â–¶]
  3 => array:6 [â–¶]
  4 => array:6 [â–¶]
  5 => array:6 [â–¶]
  6 => array:6 [â–¶]
  7 => array:6 [â–¶]
  8 => array:6 [â–¶]
  9 => array:6 [â–¶]
  10 => array:6 [â–¶]
  11 => array:6 [â–¶]
  12 => array:6 [â–¶]
  13 => array:6 [â–¶]
  14 => array:6 [â–¶]
]

index 1 ~ n ke dua adalah isi dari field column by row

sesudah di remove index 0 dan yg tersisa hanya isi by row

^ array:14 [â–¼
  1 => array:6 [â–¼
    0 => "3/26/2020"
    1 => 204
    2 => 89
    3 => 17
    4 => 0
    5 => 4
  ]
  2 => array:6 [â–¼
    0 => "3/27/2020"
    1 => 207
    2 => 99
    3 => 17
    4 => 0
    5 => 4
  ]
  3 => array:6 [â–¶]
  4 => array:6 [â–¶]
  5 => array:6 [â–¶]
  6 => array:6 [â–¶]
  7 => array:6 [â–¶]
  8 => array:6 [â–¶]
  9 => array:6 [â–¶]
  10 => array:6 [â–¶]
  11 => array:6 [â–¶]
  12 => array:6 [â–¶]
  13 => array:6 [â–¶]
  14 => array:6 [â–¶]
]

step by step

  1. remove atau unset column pada index 0

  2. buat model dan method save atau insert

  3. loop data readfile remove fieldnya

buat model 

class DocumentModel
{
	private $table = 'documents';
	private $db;

	public function __construct()
	{
		$this->db = new Database;
	}
	
public function save($tanggal, $odp, $pdp, $positif, $sembuh, $meninggal)
	{

    // query data insert
		// (`id`, `tanggal`, `odp`, `pdp`, `positif`, `sembuh`, `meninggal`);
		$query = "INSERT INTO $this->table VALUES ('',:tanggal,:odp,:pdp,:positif,:sembuh,:meninggal)";
		$this->db->query($query);

		// binding untuk data string
		$this->db->bind('tanggal', $tanggal);
		$this->db->bind('odp', $odp);
		$this->db->bind('pdp', $pdp);
		$this->db->bind('positif', $positif);
		$this->db->bind('sembuh', $sembuh);
		$this->db->bind('meninggal', $meninggal);

    // execute insert atau save data
		$this->db->execute();
		return $this->db->rowCount();
	}
}

pada controllernya

public function store()
	{
		// code here store here
		$file_excel = office::read_file_csv("files");

		// remove column
		unset($file_excel->worksheet[0]);

		// call model
		$excel = model("DocumentModel");

		// loop mutiple insert
		foreach($file_excel->worksheet as $key){
			$excel->save($key[0],$key[1],$key[2],$key[3],$key[4],$key[5]);
		}
		
	}
