Przesyłanie wielu plików (Array) za pomocą CodeIgniter 2.0
Szukałam i walczyłam od 3 dni, żeby to zadziałało, ale po prostu nie mogę. To, co chcę zrobić, to użyć formularza wprowadzania wielu plików, a następnie przesłać je. Nie mogę po prostu użyć ustalonej liczby plików do przesłania. Próbowałem wielu wielu rozwiązań na StackOverflow, ale nie byłem w stanie znaleźć działającego.
Oto mój Kontroler uploadu
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url','html'));
}
function index()
{
$this->load->view('pages/uploadform', array('error' => ' ' ));
}
function do_upload()
{
$config['upload_path'] = './Images/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload');
foreach($_FILES['userfile'] as $key => $value)
{
if( ! empty($key['name']))
{
$this->upload->initialize($config);
if ( ! $this->upload->do_upload($key))
{
$error['error'] = $this->upload->display_errors();
$this->load->view('pages/uploadform', $error);
}
else
{
$data[$key] = array('upload_data' => $this->upload->data());
$this->load->view('pages/uploadsuccess', $data[$key]);
}
}
}
}
}
?>
Mój formularz uploadu jest taki.
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php echo $error;?>
<?php echo form_open_multipart('upload/do_upload');?>
<input type="file" multiple name="userfile[]" size="20" />
<br /><br />
<input type="submit" value="upload" />
</form>
</body>
</html>
Ciągle mam ten błąd:
Nie wybrałeś pliku do upload.
Oto tablica przykładu:
Array ([userfile] = > Array ( [nazwa] = > Array ( [0] = > youtube.png [1] = > zergling.jpg ) [type] => Array ( [0] => image/png [1] => image/jpeg) [tmp_name] = > Array ([0] => E:\wamp\tmp\php7AC2.tmp [1] => E:\wamp\tmp\php7AC3.tmp) [error] = > Array ( [0] => 0 [1] => 0 ) [size] = > Array ( [0] => 35266 [1] => 186448 ) ) )
Mam to z 5 razy z rzędu, jeśli zaznaczę 2 pliki. Korzystam również ze standardowego Prześlij bibliotekę.

W końcu udało mi się to zrobić z twoją pomocą!
Oto Mój kod:
function do_upload()
{
$this->load->library('upload');
$files = $_FILES;
$cpt = count($_FILES['userfile']['name']);
for($i=0; $i<$cpt; $i++)
{
$_FILES['userfile']['name']= $files['userfile']['name'][$i];
$_FILES['userfile']['type']= $files['userfile']['type'][$i];
$_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
$_FILES['userfile']['error']= $files['userfile']['error'][$i];
$_FILES['userfile']['size']= $files['userfile']['size'][$i];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
}
}
private function set_upload_options()
{
//upload an image options
$config = array();
$config['upload_path'] = './Images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
return $config;
}
Dziękuję wam!

Powinieneś użyć tej biblioteki do wielokrotnego uploadu w CI https://github.com/stvnthomas/CodeIgniter-Multi-Upload
Instalacja wystarczy skopiować MY_Upload.plik php do katalogu biblioteki aplikacji.
Użyj: function test_up w kontrolerze
public function test_up(){
if($this->input->post('submit')){
$path = './public/test_upload/';
$this->load->library('upload');
$this->upload->initialize(array(
"upload_path"=>$path,
"allowed_types"=>"*"
));
if($this->upload->do_multi_upload("myfile")){
echo '<pre>';
print_r($this->upload->get_multi_upload_data());
echo '</pre>';
}
}else{
$this->load->view('test/upload_view');
}
}
Upload_view.php w folderze applications/view / test
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="myfile[]" id="myfile" multiple>
<input type="submit" name="submit" id="submit" value="submit"/>

Spróbuj tego kodu.
It ' s working fine for me
Musisz inicjalizować za każdym razem bibliotekę
function do_upload()
{
foreach ($_FILES as $index => $value)
{
if ($value['name'] != '')
{
$this->load->library('upload');
$this->upload->initialize($this->set_upload_options());
//upload the image
if ( ! $this->upload->do_upload($index))
{
$error['upload_error'] = $this->upload->display_errors("<span class='error'>", "</span>");
//load the view and the layout
$this->load->view('pages/uploadform', $error);
return FALSE;
}
else
{
$data[$key] = array('upload_data' => $this->upload->data());
$this->load->view('pages/uploadsuccess', $data[$key]);
}
}
}
}
private function set_upload_options()
{
//upload an image options
$config = array();
$config['upload_path'] = 'your upload path';
$config['allowed_types'] = 'gif|jpg|png';
return $config;
}
Further edit
Znalazłem sposób, w jaki musisz przesłać swoje pliki za pomocą jednego unikalnego pola wprowadzania
CodeIgniter nie obsługuje wielu plików. Użycie metody do_upload () w foreach nie będzie inne niż użycie jej Na Zewnątrz.
Będziesz musiał sobie z tym poradzić bez pomocy CodeIgniter. Oto przykład https://github.com/woxxy/FoOlSlide/blob/master/application/controllers/admin/series.php#L331-370
To jest to, co powiedziałeś w komentarzach:)

$files = $_FILES;

Wszystkie opublikowane pliki będą dostępne w zmiennej $_FILES, aby użyć biblioteki wysyłania codeigniter musimy podać field_name, której używamy do wysyłania (domyślnie będzie to 'userfile'), więc otrzymujemy wszystkie opublikowane pliki i tworzymy kolejną tablicę plików, która tworzy naszą własną nazwę dla każdego pliku, i nadajemy tę nazwę funkcji do_upload biblioteki codeigniter.

W codeigniter nie ma predefiniowanej metody przesyłania wielu plików jednocześnie, ale możesz wysłać plik w tablicy i przesłać je jeden po drugim
Tutaj jest patrz: tutaj jest najlepsza opcja, aby przesłać wiele plików w codeigniter 3.0.1 z podglądem https://codeaskbuzz.com/how-to-upload-multiple-file-in-codeigniter-framework/

Ostatnio nad tym pracuję. Spróbuj tej funkcji:
/**
* @return array an array of your files uploaded.
*/
private function _upload_files($field='userfile'){
$files = array();
foreach( $_FILES[$field] as $key => $all )
foreach( $all as $i => $val )
$files[$i][$key] = $val;
$files_uploaded = array();
for ($i=0; $i < count($files); $i++) {

if ($this->upload->do_upload($field))
$files_uploaded[$i] = $this->upload->data($files);
else
$files_uploaded[$i] = null;
}
return $files_uploaded;
}
W Twoim przypadku:
<input type="file" multiple name="images[]" size="20" />
Lub
<input type="file" name="images[]">
<input type="file" name="images[]">
<input type="file" name="images[]">
W kontrolerze:
public function do_upload(){
$config['upload_path'] = './Images/';
$config['allowed_types'] = 'gif|jpg|png';
//...
$this->load->library('upload',$config);
if ($_FILES['images']) {

Zapisz, a następnie zmień definicję zmiennej $_FILES na dowolną. może nie jest to najlepsze rozwiązanie, ale to zadziałało.
function do_upload()
{
$this->load->library('upload');
$this->upload->initialize($this->set_upload_options());
$quantFiles = count($_FILES['userfile']['name']);
for($i = 0; $i < $quantFiles ; $i++)

'size' => $_FILES['userfile']['size'][$i]
)
);
}
for($i = 0; $i < $quantFiles ; $i++)
