$_FILES Array getting empty when using $this->form_validation->run()

step by step...
Change your model and return the last_inserted_id.
In your controller, change this part of code to:

PHP Code:

if($this->form_validation->run())
           {
               $prop_title = ucwords(strtolower($this->security->xss_clean($this->input->post('prop_title'))));
               $prop_status = ucwords(strtolower($this->security->xss_clean($this->input->post('prop_status'))));
               $prop_type = ucwords(strtolower($this->security->xss_clean($this->input->post('prop_type'))));
               $prop_price = $this->security->xss_clean($this->input->post('prop_price'));
               $prop_sqft = $this->security->xss_clean($this->input->post('prop_sqft'));
               $prop_rooms = $this->security->xss_clean($this->input->post('prop_rooms'));
               $prop_address = $this->security->xss_clean($this->input->post('prop_address'));
               $prop_owner_name = $this->security->xss_clean($this->input->post('prop_owner_name'));
               $prop_owner_email = $this->security->xss_clean($this->input->post('prop_owner_email'));
               $prop_owner_phone = $this->security->xss_clean($this->input->post('prop_owner_phone'));
               $prop_detailed_info = $this->security->xss_clean($this->input->post('prop_detailed_info'));
               $prop_current_status = $this->security->xss_clean($this->input->post('prop_current_status'));
                $propertyInfo = array('title'=>$prop_title, 'status'=>$prop_status, 'type'=>$prop_type, 'price'=>$prop_price,
                                      'sqft'=>$prop_sqft, 'rooms'=>$prop_rooms, 'address'=>$prop_address, 'name'=>$prop_owner_name,
                                      'email'=>$prop_owner_email, 'phone'=>$prop_owner_phone, 'detailedInfo'=>$prop_detailed_info,
                                      'currentStatus'=>$prop_current_status);
               $result = $this->property_model->addNewProperty($propertyInfo);
echo $result.'<br>';
               if (!empty($_FILES)) {
                   $count_img = count($_FILES['file']['name']);
                   foreach($_FILES['file']['tmp_name'] as $key => $value) {

                    $tempFile = $_FILES['file']['tmp_name'][$key];
                    $fileName = $_FILES['file']['name'][$key];
                    $targetPath = 'property-images/';
                    $targetFile = $targetPath . $fileName ;

                    //$this->load->model('user_model');

                    $imgData = array('path'=>$targetFile,'propertyid'=>$result);

                    if(move_uploaded_file($tempFile, $targetFile))
                    {
                        echo 'Move upload file and add propertyImgs<br>';
                        $this->property_model->addPropertyImgs($imgData);
                    }
                   }
               } else {
                   echo '$_FILES is empty';
               }
die();
             } 


and post the result
