php mkdir不工作

Question

So I have this pretty straight foreword code for creating a dir with the name the user inputs, but it just won't create. The folder I am wanting to create it in is a subfoolder. When i test it locally it works just fine but then on the server there seems to be a problem. Can anyone help me ?

$title = str_replace(" ", "_", $_POST['title']);
if (!is_dir("uploads/".$title)){
        mkdir("uploads/".$title, 0777);

I guess it lies with the path ? But I just couldn't find out why.

Thanx guys

For most hosting providers, you have to provide a full path, not a relative one:

$root = dirname(__FILE__); // or whatever what points to root dir

$target = $root.'/uploads/'.$title; // save to a variable, to not repeat

if (!is_dir($target) {
     mkdir($target, 0777);
}
