注册时根据ID创建文件夹

Question

I have my register form and when some one registers I want to create a file with the name of there user id, then I want to right a index.php with code that will redirect to the main site.

the location I need the folder to create is example.com/uploads this will be for there images and stuff..

the issue I am having is it refuses to create the folder.

    function create_user($email, $full_name, $job_title, $password){

        if (email_exists($email)) {
            return false;
        } else {        

                $hashed_password = password_hash($password, PASSWORD_BCRYPT);

                $db = dbconnect();
                $stmt = $db->prepare('INSERT INTO users(Email, FullName, JobTitle, Bio, Password, ValidationCode, Active) VALUES (?,?,?,?,?,?,?)');
                $stmt->bind_param('sssssss', $email, $full_name, $job_title, $bio, $hashed_password, $validation_code, $active);
                $stmt->execute();
                $last_row = $stmt->insert_id;
                $stmt->close(); 



           $MainFolder ="uploads";
        $dir = $stmt->insert_id;            


        $file_to_write = 'index.php';           

        if( is_dir($dir) === false ){
            mkdir($dir);
        }
        $file = fopen($MainFolder.'/'. $dir . '/' . $file_to_write,"w");

        // write content into
        fwrite($file,"<?php header('location: http://example.com');");                                    

                return true;
            }
    }

Change your current code:

$dir = $last_row;

Into:

$dir = $stmt->insert_id;

Then echo that value to make sure you're getting results. Also enable error_reporting or check your error log to see any errors.
