How to rename more than 1 file during upload ? Codeigniter - php

Question

I have a form to upload about 5 files,
lets say it is a photo of the person who is registering and other document about him.
now i'm creating a folder for every registered user with their name ( btw, is it good thing to do? ), and i want to rename each file with the right name let say photo,document A,document B and etc.
my current code
$upload_setting['upload_path'] = './uploads/'.$_POST['name'].'/';
$upload_setting['allowed_types'] = 'jpg|pdf';
$upload_setting['max_size'] = 5000; // 5 MB
$upload_setting['file_name'] = $_POST['name']; // this define the uploaded file name
$this->load->library('upload', $upload_setting);
if ($this->form_validation->run() == FALSE){
$this->load->view('form');
}
else{
if (!is_dir('./uploads/'.$_POST['name'].'/')) {
mkdir('./uploads/'.$_POST['name'].'/', 0777, TRUE);
}
$this->member->register($this->input->post(NULL, TRUE));
$this->upload->do_upload('photo');
$this->upload->do_upload('document-A');
$this->upload->do_upload('document-B');
Also how can i let them free to upload JPG,PDF,DOC ?
i have to link these file in their profile page.
how can i know what extension they upload for each document ?
Please let me know if you have any suggestion or best practice to do this upload and then display each upload in their profile.
Thanks

To know the extension of your file you can use-
$newname= "name";
$path_parts = pathinfo($_FILES["picture"]["name"]);
$file_newname = $newname.'.'.$path_parts['extension'];
To Upload-
if( $_FILES['picture']['name'] )
{
$config['upload_path'] = 'images/receipt/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['file_name'] = $file_newname; //Here your file is being renamed
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('picture'))
{
$error = array('error' => $this->upload->display_errors());
return false;
}
}
