Class instantiation issue with CI 3.0.2 & PHP 5.6 - sjefferson - 10-19-2015
I just upgraded an existing app to CI v3.02 & PHP v5.6. I'm running into a conflict when instantiating a class then accessing certain methods in $this var, the methods seem to be overwritten by the new class instance. Here is an example, imagine the first line is being called from some other class:
PHP Code:
$upload = (new Post)->uploadImage($data);
class Post extends Main {
public function __construct(){parent::__construct();}
public function uploadImage($data){
...
$upload_dir = $this->config->item('upload_dir');
$this->load->library('upload', $config);
$upload_result = $this->upload->do_upload($field);
...
}
}
$this->config is returning the expected value I have in my config file.
$this->upload is throwing the error "Undefined property: Post::$upload" which means it has overwritten the upload library in CodeIgniter. How can I avoid this from happening?
A few notes:
- This was not happening in the previous code I had when instantiating the class by using Post::uploadImage(...)
- There is no upload() method in the Post class, nor is there code that resets $this->upload
- If I add $CI =& get_instance(); then replace $this with $CI, I get the same issue.
I'd appreciate any help. Thank you.

Is CI_Controller an ancestor of that class? Controllers in CI are singletons, you're not supposed to instantiate more than one.

Yes, CI_Controller was an ancestor of the Post class. Thanks for pointing out that they're singletons. I corrected the issue by eliminating multiple calls to the controllers.
