File extension is change upper case to lower case in codeigniter

Question

I am uploading file in codeigniter using

$this->upload->do_upload('image')

but when file moves to particular path the file extension is changed (it's changed to lower case)

for example if I upload file "profile.JPG" it's changes to "profile.jpg"

Answer 1

please change CI system library

default in CI upload library $file_ext_tolower = FALSE.

.system\libraries\upload.php

public $file_ext_tolower = TRUE;
