I was able to store and save multiple files in the array into the database, as well as updating the form data. However, the problem now is it returns this error when I update the form without updating the file.
count(): Parameter must be an array or an object that implements Countable
Does anyone know what should I do for my update function or value in my blade file so that it won't delete the file elements?
--------------------------------------------- UPDATED ---------------------------------------------
public function update(Request $request, $id)
{
$data = $request->all();
$data = $this->saveEmptyData($data);
$c = Document::find($id);
$fileData = [];
if(count($request->file)>0)
{
foreach($request->file as $file)
{
$path = public_path('storage/documents');
$fileName = time().'_'.$file->getClientOriginalName();
$file->move($path, $fileName);
if ($c->file)
{
File::delete($path.'/'.json_decode($c->file)[0]);
}
$fileData[] = $fileName;
}
$doc = json_encode($fileData);
$c->file = $doc;
$c->name = $request->name;
$c->price = $request->price;
$c->publish = $request->publish;
}
//else {
// redirect()->back()->with('errors', 'File is required!');

$c->save();
return redirect()->route('product.index')->with('success', 'Document updated successfully');

I need some help. I have a problem with store function with array in laravel. When I submit my form, I got error massage that "ksort() expects parameter 1 to be array, string given".
This is my store function :
public function store(request $request) {
$input=$request->all();
$images=array();
$total = count($request->path_scan_ijazah);
// return $total;
if($files=$request->file('path_scan_ijazah')){
for ($i=0; $i < $total; $i++) {
$nip[] = $request->nip;
$instansi[] = $request['nama_instansi_pendidikan'][$i];
$jurusan[] = $request['nama_jurusan'][$i];
$jenjang[] = $request['jenjang_pendidikan'][$i];
$gelar[] = $request['gelar'][$i];
$thn_masuk = $request['tahun_masuk'][$i];
$thn_lulus = $request['tahun_lulus'][$i];
$path = $request['path_scan_ijazah'][$i]->store('public/upload/ijazah');
$images[] = $path;

Please help me, what should I do?
My codeigniter photo gallery upload multiple image in single click. Image upload with encrypted name but name save in database original image name.I want to save in database those encrypted name.
My controller code is:
public function file_upload2(){
if($this->session->userdata('is_loged_in')){
$config = array();
$config['image_library'] = 'gd2';
$config['upload_path'] = './photo/'; //give the path to upload the image in folder
$config['allowed_types'] = 'gif|jpg|png|jpeg|JPG';
$config['max_size'] = 0;
$config['maintain_ratio'] = FALSE;
$config['encrypt_name'] = TRUE;
$config['overwrite'] = TRUE;
$this->form_validation->set_rules('category', 'Category', 'required|trim');
if ($this->form_validation->run() == TRUE){
$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];
$this->upload->initialize($config);
$this->upload->do_upload();
$fileName = $_FILES['userfile']['name'];
$images[] = $fileName;
}
$category = $this->input->post('category');
$fileName = implode(',',$images);
$this->Upload_model->upload_image($fileName,$category);
if($this->upload->do_upload()){
$this->success();
} else {
$this->index();
}
} else {
$this->index();
}
} else {
redirect('admin');
}
}
My Model:
public function upload_image($fileName,$category){
if($fileName!='' ){
$filename1 = explode(',',$fileName);
foreach($filename1 as $file){
$file_data = array(
'name' => $file,
'datetime'=> date('Y-m-d h:i:s'),
'category'=> $category
);
$this->db->insert('photo', $file_data);
}
}
}
When you uploading, use the codeigniter's upload data, since php $_FILES array doesn't know anything about the encrypted name:
if ($this->upload->do_upload()) {
$data = $this->upload->data();
echo $data['file_name']; // Here is the encrypted filename
}
I've been searching and struggling for 3 days now to make this works but I just can't.
What I want to do is use a Multiple file input form and then upload them. I can't just use a fixed number of file to upload. I tried many many solutions on StackOverflow but I wasn't able to find a working one.
Here's my Upload controller
<?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]);
}
}
}
}
}
?>
My upload form is This.
<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>
I just keep having this error :
You did not select a file to upload.
Here's the array of the example:
Array ( [userfile] => Array ( [name] => 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 ) ) )
I have this like 5 times in a row if I select 2 files.
I also use the standard Upload library.
I finally managed to make it work with your help!
Here's my code:
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 $config;
}
Thank you guys!
You should use this library for multi upload in CI https://github.com/stvnthomas/CodeIgniter-Multi-Upload
Installation Simply copy the MY_Upload.php file to your applications library directory.
Use: function test_up in controller
public function test_up(){
if($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{
$this->load->view('test/upload_view');
}
}
upload_view.php in applications/view/test folder
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="myfile[]" id="myfile" multiple>
<input type="submit" name="submit" id="submit" value="submit"/>
Try this code.
It's working fine for me
You must initialize each time the library
function do_upload()
{
foreach ($_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
I have found the way you must upload your files with one unique input box
CodeIgniter doesn't support multiple files. Using the do_upload() in a foreach won't be different than using it outside.
You will need to deal with it without the help of CodeIgniter. Here's an example https://github.com/woxxy/FoOlSlide/blob/master/application/controllers/admin/series.php#L331-370
https://stackoverflow.com/a/9846065/1171049
This is that said you in the commments :)
another bit of code here:
refer: https://github.com/stvnthomas/CodeIgniter-Multi-Upload
As Carlos Rincones suggested; don't be affraid of playing with superglobals.
$files = $_FILES;
for($i=0; $i<count($files['userfile']['name']); $i++)
{
$_FILES = array();
foreach( $files['userfile'] as $k=>$v )
{
$_FILES['userfile'][$k] = $v[$i];
}
$this->upload->do_upload('userfile')
}
All Posted files will be come in $_FILES variable, for use codeigniter upload library we need to give field_name that we are using in for upload (by default it will be 'userfile'), so we get all posted file and create another files array that create our own name for each files, and give this name to codeigniter library do_upload function.
if(!empty($_FILES)){
$j = 1;
foreach($_FILES as $filekey=>$fileattachments){
foreach($fileattachments as $key=>$val){
if(is_array($val)){
$i = 1;
foreach($val as $v){
$field_name = "multiple_".$filekey."_".$i;
$_FILES[$field_name][$key] = $v;
$i++;
}
}else{
$field_name = "single_".$filekey."_".$j;
$_FILES[$field_name] = $fileattachments;
$j++;
break;
}
}
// Unset the useless one
unset($_FILES[$filekey]);
}
foreach($_FILES as $field_name => $file){
if(isset($file['error']) && $file['error']==0){
$config['upload_path'] = [upload_path];
$config['allowed_types'] = [allowed_types];
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ( ! $this->upload->do_upload($field_name)){
$error = array('error' => $this->upload->display_errors());
echo "Error Message : ". $error['error'];
}else{
$data = $this->upload->data();
echo "Uploaded FileName : ".$data['file_name'];
// Code for insert into database
}

There is no predefined method available in codeigniter to upload multiple file at one time but you can send file in array and upload them one by one
here is refer: Here is best option to upload multiple file in codeigniter 3.0.1 with preview https://codeaskbuzz.com/how-to-upload-multiple-file-in-codeigniter-framework/
SO what I change is I load upload library each time
$config = array();
$config['upload_path'] = $filePath;
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
$files = $_FILES;
$count = count($_FILES['nameUpload']['name']);
for($i=0; $i<$count; $i++)
{
$this->load->library('upload', $config);
$_FILES['nameUpload']['name']= $files['nameUpload']['name'][$i];
$_FILES['nameUpload']['type']= $files['nameUpload']['type'][$i];
$_FILES['nameUpload']['tmp_name']= $files['nameUpload']['tmp_name'][$i];
$_FILES['nameUpload']['error']= $files['nameUpload']['error'][$i];
$_FILES['nameUpload']['size']= $files['nameUpload']['size'][$i];
$this->upload->do_upload('nameUpload');
}
And it work for me.

I recently work on it. Try this function:
/**
* #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++) {
$_FILES[$field] = $files[$i];
if ($this->upload->do_upload($field))
$files_uploaded[$i] = $this->upload->data($files);
else
$files_uploaded[$i] = null;
}
return $files_uploaded;
}
in your case:
<input type="file" multiple name="images[]" size="20" />
or
<input type="file" name="images[]">
<input type="file" name="images[]">
<input type="file" name="images[]">
in the controller:
public function do_upload(){
$config['upload_path'] = './Images/';
$config['allowed_types'] = 'gif|jpg|png';
//...
$this->load->library('upload',$config);
if ($_FILES['images']) {
$images= $this->_upload_files('images');
print_r($images);
}
}
Some basic reference from PHP manual: PHP file upload
Save, then redefine the variable $_FILES to whatever you need.
maybe not the best solution, but this worked for me.
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++)

the separate function to establish the config..
private function set_upload_options()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'xml|pdf';
$config['max_size'] = '10000';
return $config;
}
I am trying to upload multiple images and I have a jquery plugin set up so I can browse for multiple files and select them.
The only problem I am having is accessing the file array in my controller, does anyone know how I can do this? Thanks.
view:
<input type="file" name="userfile[]" id="userfile" class="multi" />
I had this same issue on a project last year, after a bit of searching I found a perfect function.
I take no credit it for it, but cannot remmeber where I found it so if anyone knows please link back to the author.
Make sure the form has the files named like this
<input type="file" name="userfile"/>
<input type="file" name="userfile2" />
<input type="file" name="userfile3" /> ..etc
Or
<input type="file" name="userfile[]" />
The function..
function multiple_upload($upload_dir = 'uploads', $config = array())
{
$files = array();
if(empty($config))
{
$config['upload_path'] = '../path/to/file';
$config['allowed_types'] = 'gif|jpg|jpeg|jpe|png';
$config['max_size'] = '800000000';
}
$this->load->library('upload', $config);
$errors = FALSE;
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
if( ! $this->upload->do_upload($key))
{
$data['upload_message'] = $this->upload->display_errors(ERR_OPEN, ERR_CLOSE); // ERR_OPEN and ERR_CLOSE are error delimiters defined in a config file
$this->load->vars($data);
$errors = TRUE;
}
else
{
// Build a file array from all uploaded files
$files[] = $this->upload->data();
}
}
}
// There was errors, we have to delete the uploaded files
if($errors)
{
foreach($files as $key => $file)
{
#unlink($file['full_path']);
}
}
elseif(empty($files) AND empty($data['upload_message']))
{
$this->lang->load('upload');
$data['upload_message'] = ERR_OPEN.$this->lang->line('upload_no_file_selected').ERR_CLOSE;
$this->load->vars($data);
}
else
{
return $files;
}
}
Now it's been a while since I've used it so if you need any extra help setting it up just let me know.
To use Jquery multiple upload using html elements array [] developed as follows in the act of receiving data sobrescrevi the global variable $ _FILES PHP so that the function do_upload could read later. see:
#copy the original array;
$temp_array;
foreach($_FILES['fil_arquivo'] as $key => $val)
{
$i = 0;
foreach($val as $new_key)
{
$temp_array[$i][$key] = $new_key;
$i++;
}
//
}
$i = 0;
foreach($temp_array as $key => $val)
{
$_FILES['file'.$i] = $val;
$i++;
}
#clear the original array;
unset($_FILES['fil_arquivo']);
$upload_path = 'media/arquivos';
$config['upload_path'] = $upload_path;
$config['allowed_types'] = 'doc|docx|xls|xlsx|ppt|pptx|pdf|txt|jpg|png|jpeg|bmp|gif|avi|flv|mpg|wmv|mp3|wma|wav|zip|rar';
$config['encrypt_name'] = true;
$this->upload->initialize($config);
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
if($this->upload->do_upload($key))
{
$this->upload->data();
}
}
}
The HTML provided by ojjwood above will produce multiple input boxes. If you'd only like to have one input box but still upload multiple files, you need to include the attribute multiple="multiple" in your <input> element. The [] in name="userfile[]" allows the posted data to be an array and not just a single value.
On the Codeigniter/PHP side of things, you need to use $_POST['userfile] instead of $this->input->post('userfile') for working with arrays.
