Codeigniter file uploading issue - php

Question

I'm trying to upload image files using codeigniter 3 but it's not working. No matter what I do, it always says "You didn't select a file to upload". It logs an error on the console saying error 500 when i click on the error in the Network tab then it redirects me to a new tab where it says that error.
Here is my HTML Code:
<div id="container">
<h1>Welcome to CodeIgniter!</h1>
<div id="body">
<form method="post" enctype="multipart/form-data" action="<?php echo base_url('index.php/welcome/upload'); ?>">
<input type="text" name="username" value="Zahid Saeed">
<input type="file" name="profile_img">
<button type="submit">Submit Form</button>
</form>
</div>
and here is my controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper("url");
}
public function index()
{
$this->load->view('welcome_message');
}
public function upload() {
$config = array(
"upload_path" => "./uploads/",
"allowed_types" => "gif|jpg|png"
);
echo "<pre>";
print_r($this->input->post());
print_r($_FILES);
echo "</pre>";
$this->load->library("upload", $config);
$this->upload->initialize($config);
if(!$this->upload->do_upload("profile_img")) {
echo $this->upload->display_errors();
echo "IN IF";
}
else {
echo "img uploaded successfully";
}
}
}
One more thing, the exact code is working on the linux machine and in fact on the server. But it's not working on my laptop. I'm using Windows 8.1
Thanks in Advance

Answer 1

may be its php.ini problem
Open your php.ini file
search for extension=php_fileinfo.dll
if you are using xampp it may be commented by default
change
;extension=php_fileinfo.dll
to
extension=php_fileinfo.dll
and restart your xampp...
this was solve my problem

Answer 2

Might be a good idea to use absolute paths for your upload path
$this->upload_config['upload_path'] = FCPATH . 'uploads/';
When I run your code, it works under WAMP64 on Windows 10 Home, ie the file is uploaded and I get to see
Array
(
[username] => Zahid Saeed
)
Array
(
[profile_img] => Array
(
[name] => header-background.png
[type] => image/png
[tmp_name] => C:\wamp64\tmp\php34DA.tmp
[error] => 0
[size] => 563
)
)
img uploaded successfully

This code not supporting obj and fbx formats for file uploading what i do change for this
class Welcome extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper("url");
}
public function index()
{
$this->load->view('welcome_message');
}
public function upload() {
$config = array(
"upload_path" => "./uploads/",
"allowed_types" => "gif|jpg|png"
);
echo "<pre>";
print_r($this->input->post());
print_r($_FILES);
echo "</pre>";
$this->load->library("upload", $config);
$this->upload->initialize($config);
if(!$this->upload->do_upload("profile_img")) {
echo $this->upload->display_errors();
echo "IN IF";

//check here if file is not empty
if(!empty($_FILES['attach_file']['name'])){
$config['upload_path'] = APPPATH.'../assets/images/'; $config['allowed_types'] = 'jpg|jpeg|png|mp4'; $config['file_name'] = 'attach_file_'.time(); $config['max_size'] = "1024";$config['max_height']= "800";$config['max_width'] = "1280";$config['overwrite'] = false;$this->upload->initialize($config);if(!($this->upload->do_upload("attach_file"))){$data['error']['attach_file'] = $this->upload->display_errors();else{ $coverPhotoData = $this->upload->data(); $coverPhoto =$coverPhotoData['file_name'];}}elseif($this->input->get('cup')){$coverPhoto = $previous['attach_file'];}
