codeigniter renaming file in directory

[c_pattle]

I have an image uploader that works well and stores the name of the file uploaded in a session.  Once the files has been uploaded how do I then rename that file? 

 

I would rename it during the uploaded but I need to rename it to an order number and I only get that order number after the image has been uploaded. 

 

Thanks for any help.

Firstly, if you're using the 'File Uploading' class in CodeIgniter, this user_guide will help.

 

If you want to do the renaming process using the core PHP functions, you need to use the rename() function.

 

An example of this is:

<?php
rename("/path/to/uploaded-file.txt", "/path/to/new-filename.txt");
?>

 

Of course your directory will need to also be using the correct permissions for the rename.

 

I hope this helped.

if you are using the uploader class, rename the file during uploading, $config['file_name'] = $_FILES['userfile']['name'].'what you want the file name to be';
