How to multiupload images in Codeigniter - codeigniter

Question

I'm trying to do multi upload photos to the form in Codeigniter 3. When I want to upload photos, clicking upload sends me the entire form and adds only one photo. If anyone could give me tips on how to do this, I would be grateful. I could do it as two separate forms but then it doesn't work as I would like.
My form view
<form method='post' action='<?php echo base_url();?>ads/create' enctype='multipart/form-data'>
<div class="form-group row">
<label for="email" class="col-4 col-form-label text-uppercase text-right">Tytuł :</label>
<div class="col-8">
<input type="text" class="form-control" name="title" value="<?php echo set_value('title'); ?>">
</div>
</div>
<div class="form-group row">
<label for="message" class="col-4 col-form-label text-uppercase text-right">Opis ogłoszenia:</label>
<div class="col-8">
<textarea name="description" id="message" cols="70" rows="5"
class="form-control" ><?php echo set_value('description'); ?></textarea>
</div>
</div>
<div class="form-group row">
<label for="contact" class="col-4 col-form-label text-uppercase text-right">Osoba do kontaktu:</label>
<div class="col-8">
<input type="text" class="form-control" name="contact" value="<?php echo set_value('contact'); ?>">
</div>
</div>
<div class="form-group row">
<label for="email" class="col-4 col-form-label text-uppercase text-right">Adres email:</label>
<div class="col-8">
<input type="text" class="form-control" name="email" <?php if ( logged_in() == true )
{ echo "value='".$user->email."' disabled"; } ?> >
</div>
</div>
<div class="form-group row">
<label for="phone" class="col-4 col-form-label text-uppercase text-right">Numer telefonu:</label>
<div class="col-8">
<input type="text" class="form-control" name="phone" value="<?php echo set_value('phone'); ?>">
</div>
</div>
<div class="form-group row">
<label for="message" class="col-4 col-form-label text-uppercase text-right">Zdjęcia:</label>
</div>
<hr>
<input type='file' name='files[]' multiple=""> <br/><br/>
<input id="submit" type='submit' value='Upload' name='upload' />
<strong><?php if(isset($totalFiles)) echo "Successfully uploaded ".count($totalFiles)." files"; ?></strong>
<div class="form-group row">
<div class="col-12 text-center">
<button class="btn btn-primary w-50 mt-3">Dodaj</button>
</div>
</div>
<?php echo form_close(); ?>
And my controller
public function create()
{
$user_id = $this->session->userdata( 'id' );
$where = array( 'id' => $user_id);
$user = $this->Site_model->get_single('users', $where);

Answer 1

You should change
if($this->upload->do_upload('file')){
into
if($this->upload->do_upload('files')){

Answer 2

in this example you you have single image upload and multiple image upload different folders.
if ($param =="upload") {
$config['upload_path'] = './uploads/user_profil/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 15000;
$config['file_name'] = $this->input->post('user_profile')."_profil_image_".mt_rand(100000,900000);
$this->load->library('upload', $config, 'user_profile'); // Create custom object for cover upload
$this->user_profile->initialize($config);
if ( !empty($this->user_profile->do_upload('user_profil_image') ) )
{
$error = array('error' => $this->user_profile->display_errors());
$file_name_profile_picture = $this->input->post('user_profil_image_actual');
$upload_data = $this->user_profile->data();
$file_name_profile_picture = $upload_data['file_name'];
}
else
{
$file_name_profile_picture ="";
}
//map photos
$config_galery['upload_path'] = './uploads/map_profile/';
$config_galery['allowed_types'] = 'gif|jpg|png';
$config_galery['max_size'] = 15000;
$config_galery['file_name'] = $this->input->post('name')."_user_profilm_map_".mt_rand(100000,900000);
$this->load->library('upload', $config_galery, 'map_profile'); // Create custom object for cover upload
$this->map_profile->initialize($config_galery);
if ( !empty($this->map_profile->do_upload('map_profile_image')) )
{
$error = array('error' => $this->map_profile->display_errors());
$map_profile_image =$this->input->post('map_profile_image_actual');
$upload_data1 = $this->map_profile->data();
$map_profile_image = $upload_data1['file_name'];
} else {
$map_profile_image="";
}
if(!empty($_FILES['userfile']['name'])){
$b = $this->doupload_gallery();
$galery_photo_links = json_encode(json_decode($b, true));
} else {
// default empty state
$galery_photo_links ="[]";
}
if (!empty($this->input->post('profile_qr_id'))) {
$data_update_qr_status = array(
'statusi' => 1,
'table_name' => "table_name_db"
);
$this->db->where('profile_qr_id', $this->input->post('profile_qr_id'));
$this->db->update('table_name', $data_update_qr_status);
}
$this->db->insert('table_name', $data);
// ridirect
redirect(base_url('admin/uploads_view'), 'refresh');
}
