php - Codeigniter upload library get thumb file name -

I can not find any documents on this. I am uploading images

  $ config ['create_thumb'] = TRUE;   
 To build thumbs and preserve the original image  
 is there a way to get thumb image file name?  _thumb  is added automatically to the name of the thumbnail but there is no function to remove the full name.  
  
 
 
 This is actually a very easy way to do this:  
  ($ This-> upload-> do_upload ()) // if the file was uploaded {$ data = $ this-> Upload-> Data (); // Returns information about your uploaded file $ thumbnail = $ data ['raw_name'].'_ thumb ' $ Data ['file_ext']; // here it is}
