Multiple files upload (Array) with CodeIgniter 2.0

votes

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

foreach( $_FILES as $file ){ //do_upload( $file ) } - gorelative

@KemalFadillah it is actually. Gorelative, it doesn't work i get Illegal offset type in isset or empty in the upload library file - CinetiK

@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

Hi, I tried this code, Image is not moving to given folder - Vijaykarthik

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 :)

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
            }

I have used below code in my custom library
call that from my controller like below,

function __construct() {<br />
   &nbsp;&nbsp;&nbsp; parent::__construct();<br />
   &nbsp;&nbsp;&nbsp;   $this->load->library('CommonMethods');<br />
}<br />

$config = array();<br />
$config['upload_path'] = 'assets/upload/images/';<br />
$config['allowed_types'] = 'gif|jpg|png|jpeg';<br />
$config['max_width'] = 150;<br />
$config['max_height'] = 150;<br />
$config['encrypt_name'] = TRUE;<br />
$config['overwrite'] = FALSE;<br />

// upload multiplefiles<br />
$fileUploadResponse = $this->commonmethods->do_upload_multiple_files('profile_picture', $config);

/**
 * do_upload_multiple_files - Multiple Methods
 * @param type $fieldName
 * @param type $options
 * @return type
 */
public function do_upload_multiple_files($fieldName, $options) {

    $response = array();
    $files = $_FILES;
    $cpt = count($_FILES[$fieldName]['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES[$fieldName]['name']= $files[$fieldName]['name'][$i];
        $_FILES[$fieldName]['type']= $files[$fieldName]['type'][$i];
        $_FILES[$fieldName]['tmp_name']= $files[$fieldName]['tmp_name'][$i];
        $_FILES[$fieldName]['error']= $files[$fieldName]['error'][$i];
        $_FILES[$fieldName]['size']= $files[$fieldName]['size'][$i];    

        $this->CI->load->library('upload');
        $this->CI->upload->initialize($options);

        //upload the image
        if (!$this->CI->upload->do_upload($fieldName)) {
            $response['erros'][] = $this->CI->upload->display_errors();
        } else {
            $response['result'][] = $this->CI->upload->data();
        }
    }

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;
}
