Question

I need to rename a file name while upload in codeigniter, by default it create a file name like sample.png, sample1.png while upload a same file again, but I need to give some authentication to the files uploading with random numbers like 1234_sample.png, 1232_sample.png.

Any way to do this. ?

Thanks in advance.

In your controller BEFORE you run the actual upload code put the following:

$config['encrypt_name'] = TRUE;

As per the CodeIgniter documentation:

If set to TRUE the file name will be converted to a random encrypted
string. This can be useful if you would like the file saved with a
name that can not be discerned by the person uploading it.

This should be put before you run:

$this->load->library('upload', $config); // need to pass $config array
