Codeigniter: ottieni il nome del file caricato

Question

Come posso salvare il nome del mio file caricato in una variabile (sono nuovo in CI)?

Sto usando questo codice per il test:

Vorrei davvero apprezzare il vostro aiuto su questo ragazzi.

Questo è il codice che sto usando (e sto scrivendo questo più e più volte a causa delle restrizioni di StackOverflow):

<?php 

class Gallery_model extends CI_Model { 

    var $gallery_path; 
    var $videos_path; 
    var $thumbnail; 
    var $video_name;

     parent::__construct(); 

     $this->gallery_path = realpath(APPPATH . '../images'); 
     $this->videos_path = realpath(APPPATH . '../videos'); 
     $this->videos_path_tnumb = realpath(APPPATH . '../videos/thumb'); 

     $this->thumbnail = 'C://xampp//htdocs//upload//videos//thumb';

      'allowed_types' => 'avi|mp4|flw|mov', 
      'upload_path' => $this->videos_path

Answer 1

$upload_data = $this->upload->data(); //Returns array of containing all of the data related to the file you uploaded. 
$file_name = $upload_data['file_name'];
