Multiple files upload (Array) with CodeIgniter 2.0

Question

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 honestly find it hard to believe that `$key` is actually an array inside the `foreach` loop. — Kemal Fadillah, Jul 17 '12 at 14:39
@KemalFadillah it is actually. Gorelative, it doesn't work i get Illegal offset type in isset or empty in the upload library file — CinetiK, Jul 17 '12 at 18:31
@CinetiK if `$key` is really an array like you said, then it doesn't make any sense to pass it as an argument when you call `do_upload()`. Because the function expects one parameter that is a string. — Kemal Fadillah, Jul 18 '12 at 04:49

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!

Works for me. is there any way to make a table of all the selected files? – Bart De Kimpe Jan 23 '13 at 15:47

For that purpose I would recommend you to check how to upload files with jQuery/Ajax (also check http://www.grocerycrud.com/image-crud) – CinetiK Jan 29 '13 at 10:56
This code is also the only way I can get it to work. However it's so ugly that one need to convert the array values... Should be a more beautiful solution! Possibly extending the ul library? – jtheman Mar 01 '13 at 11:04
@jtheman Yes it's not beautiful coding I agree but that's the only solution I could find at that time and I managed to use it with Ajax upload so the app could display files while there were being uploaded. – CinetiK Sep 10 '13 at 09:39
thanks dude, its working, I edit this code to $this->upload->do_upload('userfile'); – silvia zulinka Oct 27 '16 at 06:46

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"/>

having problem with this method. something wrong in the `do_multi_upload` function. doesnt return anything. blank screen error — cyberrspiritt, Oct 19 '15 at 13:21

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 :)

it still doesn't work for me. With your function and my view (quoted above) i get > is_uploaded_file() expects parameter 1 to be string, array given in the library file Upload.php (line 161) I change the upload path of course. And it still tell me > no file selected — CinetiK, Jul 17 '12 at 22:07
I found the problem, you need another interation on the foreach, because the format of $_FILES when uses a multiple upload input is different. For example: [name] => Array ( [0] => youtube.png [1] => zergling.jpg ). Is not a array of arrays is one array with the properties as array — Sangar82, Jul 17 '12 at 22:31
So i need a function to sort of modify my "array" into a good one and then it will work right ? — CinetiK, Jul 17 '12 at 22:38

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++;

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);
    }
}

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++)
    {
        $arquivo[$i] = array
                    (
                        'userfile' => array 
                                        (
                                            'name' => $_FILES['userfile']['name'][$i],
                                            'type' => $_FILES['userfile']['type'][$i],
                                            'tmp_name' => $_FILES['userfile']['tmp_name'][$i],
                                            'error' => $_FILES['userfile']['error'][$i],
                                            'size' => $_FILES['userfile']['size'][$i]
                                        )
                    );
    }


    for($i = 0; $i < $quantFiles ; $i++)
    {
        $_FILES = '';
        $_FILES = $arquivo[$i];



        if ( ! $this->upload->do_upload())
        {
            $error[$i] = array('error' => $this->upload->display_errors());


            return FALSE;
        }
        else
        {

            $data[$i] = array('upload_data' => $this->upload->data());

            var_dump($this->upload->data());
        }


    }





    if(isset($error))
        {
            $this->index($error);
        }
        else
        {
            $this->index($data);
        }

}

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;
}
