Question

I need to create a folder to store user information at login. One login button should perform 2 actions.

Create folder
I need this in CODEIGNITER, please someone help me, I've been stuck with this for 4 weeks.
This is my code

class LoginTwo extends CI_Controller
{
function __construct() {
parent::__construct();
$this->load->model("login_model", "login");
}
public function login()
{
$username = $this->input->post("username");
$password = $this->input->post("password");
$isCorrect = $this->login->validate_user($username, $password);
if($isCorrect)
{
// Start your user session
$dirName = $username;
$dirPath = "folder/".$dirName."/";
if (!file_exists($dirPath)) {
mkdir("folder/" . $dirName, 0777, true);
}
redirect("your user page");
}
else
{
redirect("homepage");
}
}
}?>

Answer 1

Try to use below mentioned solutions.
$path = FCPATH.'/uploads/';
$new_directory = 'name';
mkdir($path.$name,0755,TRUE);
In this
First_Param: pathname :Name of directory
Second_Param: mode: Permissions
Third Param : recursive : Allows the creation of nested directories

Check out the following code. You need to fit your requirements within this code block (you can change it if you have to do something more).
You controller function :
public function login()
{
$username = $this->input->post("username");
$password = $this->input->post("password");
$isCorrect = $this->user_model->checkCredentials($username, $password);
if($isCorrect)
{
// Start your user session
$dirName = $username;
$dirPath = "folder/".$dirName."/";
if (!file_exists($dirPath)) {
mkdir("folder/" . $dirName, 0777, true);
}
redirect("your user page");
}
else
{
redirect("homepage");
}
}
