How to use Multiple images in codeigniter - codeigniter

Question

In my page I want user to select multiple images and upload it I am saving images name in database for reference. I am successful in uploading single images in database and can also show image in view but now I have problem in uploading multiple images.
public function add_record()
{
$this->form_validation->set_rules('category', 'category', 'required');
$current_date = date("Y-m-d H:i:s");
$error='';
if($this->form_validation->run())
{
$image = '';
if($_FILES['image']['name'])
{
if (!is_dir('/backend_assets/media/image/')) {
mkdir('./backend_assets/media/image/', 0777, TRUE);
}
$config['upload_path'] = './backend_assets/media/image/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ($this->upload->do_upload('image'))
{
$data = $this->upload->data();
$image = $data['file_name'];
}else{
$this->session->set_flashdata('error', $this->upload->display_errors());
redirect(base_url('admin/image'));
}
}
$insert_array = array(
'gl_cat_id' => $this->input->post('category'),
'gl_image'=> $image
);
if ($this->common_model->add_records('vm_image',$insert_array))
{
$id = $this->db->insert_id();
$insert_sco_details = array(
'sd_ty'=>'vm_image',
'sd_ty_id'=>$id,
'sd_image'=>$image
);
if($this->common_model->publication('vm_image',$id) && $this->common_model->add_records('vm_seo_detail',$insert_sco_details))
{
$this->session->set_flashdata('success','Record added successfully');
redirect(base_url('admin/image'));
}else{
$this->session->set_flashdata('error','Error while adding record');
redirect(base_url('admin/image'));
}
}else{
$this->session->set_flashdata('error','Error while adding record');
redirect(base_url('admin/image'));
}
}
$where_array = array('vm_publications.status !=' => 4);
$data['users_type'] = $this->common_model->get_records('vm_image_category','','','');
$data['include'] = 'backend/image/add_image';
$this->load->view('backend/container', $data);
}
How is it possible with above code...?

$current_date = date("Y-m-d H:i:s");
$error = '';
$image = '';
if(isset($_FILES['image']['name']))
{
//print_r($_FILES);
$id = base64_decode($this->input->post('gid'));
$filesCount = count($_FILES['image']['name']);
$inserted = '';
for($i = 0; $i < $filesCount; $i++)
{
$_FILES['userFile']['name'] = $_FILES['image']['name'][$i];
$_FILES['userFile']['type'] = $_FILES['image']['type'][$i];
$_FILES['userFile']['tmp_name'] = $_FILES['image']['tmp_name'][$i];
$_FILES['userFile']['error'] = $_FILES['image']['error'][$i];
$_FILES['userFile']['size'] = $_FILES['image']['size'][$i];
$config['upload_path'] = './backend_assets/media/image/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if($this->upload->do_upload('userFile'))
{
$fileData = $this->upload->data();
$image = $fileData['file_name'];
$insert_array = array(
'gl_cat_id' => $this->input->post('category'),
'gl_image'=> $image
);
if ($this->common_model->add_records('vm_image',$insert_array))
{
$id = $this->db->insert_id();
$insert_sco_details = array(
'sd_ty'=>'vm_image',
'sd_ty_id'=>$id,
'sd_image'=>$image
);
if($this->common_model->publication('vm_image',$id) && $this->common_model->add_records('vm_seo_detail',$insert_sco_details))
{
$inserted++;
}
}
}
}
if($inserted == $filesCount)
{ $this->session->set_flashdata('success','Images uploaded successfully');
redirect(base_url('adminp8AamG6ueHFNGAAp/image'));

$this->session->set_flashdata('error','Error while adding record');

}
}

$data['include'] = 'backend/image/add_image';
$this->load->view('backend/container', $data);

try below code in you add_record() function. it will helpful to you. few days ago, i have faced same problem
$files = $_FILES;
$count = count($_FILES['image']['name']);
for($i=0; $i<$count; $i++) {
$_FILES['image']['name']= $files['image']['name'][$i];
$_FILES['image']['type']= $files['image']['type'][$i];
$_FILES['image']['tmp_name']= $files['image']['tmp_name'][$i];
$_FILES['image']['error']= $files['image']['error'][$i];
$_FILES['image']['size']= $files['image']['size'][$i];
$this->upload->initialize($this->set_upload_options());//function defination below
$this->upload->do_upload('image');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name'];
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
and set file upload configuration in set_upload_options function in same controller.
function set_upload_options() {
$config = array();
$config['upload_path'] = PATH;
$config['remove_spaces']=TRUE;
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '78000';
return $config;
}

First, debug the output of the $_FILES variable. This should give you an array of files that are being uploaded. Loop through them to treat each one individually.
foreach ($_FILES as $file) {
// do some file processing on the $file object instead of $_FILES object.
// example: instead of using 'if($_FILES['image']['name'])'
// use: 'if($file['image']['name'])'
}
