Codeigniter: cannot upload files from subdirectory to main directory - php

Question

I'm having 2 codeigniter applications one of them in the root and the other is in a sub directory. I'm trying to upload files from the application in the sub sirectory the the images/artists folder in the root (in the main application) but I get
ERROR 404 Page Not Found: Images/artists
The upload destination folder does not appear to be writable.
I run this code in the controller which is used to upload in the sub directory application
if (file_exists('../images/artists')) {
echo 'directory exists - ';
if (!is_dir('../images/artists')) {
echo 'not a dir';
}
else{
echo 'it is a dir';
}
}
And I get "directory exists - it is a dir" and then run the upload code
$gallery_path = realpath(APPPATH . '../images/artists/');
$config['upload_path'] = $gallery_path;
$config['allowed_types'] = 'jpg|png|jpeg';
$config['max_size'] = '20000';
$config['file_name'] = round(microtime(true) * 1000).'.jpg';
$this->load->library('upload', $config);
if ($this->upload->do_upload('img')) {
$phot_data = $this->upload->data();
$photo_name = $phot_data['file_name'];
$this->resizeImage($photo_name);
$artist_data['image'] = $config['file_name'];
}
//not used here but dows it override and trigger the error?
function do_upload() {
if ($_FILES['photos']['name'][0] != '') {
$name_array = array();
foreach ($_FILES as $key => $value)
$_FILES['userfile']['name'] = $value['name'];
$_FILES['userfile']['type'] = $value['type'];
$_FILES['userfile']['tmp_name'] = $value['tmp_name'];
$_FILES['userfile']['error'] = $value['error'];
$_FILES['userfile']['size'] = $value['size'];
$config['upload_path'] = realpath(APPPATH . 'images/artists/');
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '2000';
$this->load->library('upload');
$this->upload->initialize($config);
$this->upload->do_upload();
$data = $this->upload->data();
$name_array[] = $data['file_name'];
}
redirect('admin/gallery');
}
I checked images and artists permissions and they are set to 777 Where's the issue then?

The first snippet only checks if the directory exists, but you want to confirm that it is writable (i.e. that you can put new files into it).
Check is_writable for more details. To fix the problem you'll need to run chmod 600 /path/to/images/artists on the server.
