Question

I want to automatically create a folder, using the users email address, if one does not already exists. This action should occur when they upload a file.

SOLVED. I updated this code for anyone who might need it. Thanks!

Here is my code:

if(isset($_POST["checkFile"]) && $_FILES["selectFile"]["name"] != "") {
            $target_path_pdf = "uploads/pdfs/$email/";

            if ( ! is_dir($target_path_pdf)) {
                mkdir($target_path_pdf);
            }

            $target_path_pdf = $target_path_pdf . str_replace(' ', '_', basename($_FILES["selectFile"]["name"]));
            if(move_uploaded_file($_FILES["selectFile"]["tmp_name"], $target_path_pdf)) {
            }
            else {
                $flag = 1;
            }
            $pdfcaption = $_POST['pdfCaption1'];
        }

        if(isset($_POST["checkPicture"]) && $_FILES["selectPicture"]["name"] != "") {
            $target_path_pic = "uploads/pictures/$email/";

            if ( ! is_dir($target_path_pic)) {
                mkdir($target_path_pic);
            }


            $target_path_pic = $target_path_pic . str_replace(' ', '_', basename($_FILES["selectPicture"]["name"]));
            if(move_uploaded_file($_FILES["selectPicture"]["tmp_name"], $target_path_pic)) {
            }
            else {
                $flag = 1;
            }
            $piccaption = $_POST['picCaption1'];
        }

This might not be super secure, but that’s a different problem.

For the first part:

$target_path_pdf = "uploads/pdfs/$email/";

if(!is_dir($target_path_pdf)){
    mkdir($target_path_pdf);
}

EDIT

Even though it might be obvious it can’t hurt to explain.
The script simply checks if the directory already exists, and if it doesn’t it creates one.
