Answer 1

By default codeIgniter doesn't support multi-file upload. So you can use
this library CodeIgniter Multiple Upload Library

Answer 2

I think you need to change this line:
if (!$this->upload->do_upload('files[]'))
to
if (!$this->upload->do_upload('files'))

Answer 3

you did not pass file name to upload function.Try this.
if (!$this->upload->do_upload($_FILES['files']['name']))
{
$error =['error' => $this->upload->display_errors()];
$this->load->view('admin/addGallery', $error);
}

Answer 4

try this:
$files = $_FILES;
$cpt = count($_FILES['files']['name']);
for($i=0; $i<$cpt; $i++)
{
$_FILES['files']['name']= $files['files']['name'][$i];
$_FILES['files']['type']= $files['files']['type'][$i];
$_FILES['files']['tmp_name']= $files['files']['tmp_name'][$i];
$_FILES['files']['error']= $files['files']['error'][$i];
$_FILES['files']['size']= $files['files']['size'][$i];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
$fileName = $_FILES['files']['name'];
$images[] = $fileName;
and make a function set_upload_options()
$config = array();
$config['upload_path'] = './upload/'; //give the path to upload the image in folder
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
return $config;

Answer 5

Please try bellow
for($i=0; $i<$cpt; $i++)
{
$_FILES['files'] = $files[$i];
$this->upload->initialize($this->set_upload_options());
if (!$this->upload->do_upload('files'))
{
$error =['error' => $this->upload->display_errors()];
$this->load->view('admin/addGallery', $error);
}
}

Answer 6

You can upload multiple files with CodeIgniter in a single request. You just need to do do_upload() for each file. Here's one implementation. You can work it into a loop if needed.
// Image upload Config
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1000000';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
// Upload Files
if ( $_FILES['first_file']['name'] && $this->upload->do_upload('first_file') ) {
$first_file = $this->upload->data();
}
if ( $_FILES['second_file']['name'] && $this->upload->do_upload('second_file') ) {
$second_file= $this->upload->data();
}

Answer 7

Just that i understood from the library $this->upload->do_upload('inputelementname') doesn't have to be input element name. It should be the key of files array.
So in this context this should work
if($_FILES){
$filecount=count($_FILES['addmediaelement']['name']);
for($i=0; $i<$filecount; $i++){
$_FILES['mediaelement']['name']=$_FILES['addmediaelement']['name'][$i];
$_FILES['mediaelement']['type']=$_FILES['addmediaelement']['type'][$i];
$_FILES['mediaelement']['tmp_name']=$_FILES['addmediaelement']['tmp_name'][$i];
$_FILES['mediaelement']['error']=$_FILES['addmediaelement']['error'][$i];
$_FILES['mediaelement']['size']=$_FILES['addmediaelement']['size'][$i];
$config['upload_path']=path/to/save/file;
$config['file_name']=filealternatename.extension;
$config['max_size']=MAXSIZE; //max size constant
$config['max_width']=MAXWIDTH; //max width constant
$config['max_height']=CMPMAXHEIGHT; //max height constant
$config['allowed_types']='jpg|png';
if(!is_dir($config['upload_path'])){
mkdir($config['upload_path'], 0775);
}
$this->upload->initialize($config);
$imageuploaderres[]=$this->upload->do_upload('mediaelement');
}
}
