In the past you could unconditionally call $_FILES['profile_pic'] without ever having to worry about PHP spitting an "Undefined index: profile_pic" error (so long as the page posting had a file input on it (e.g. <input type="file" name="profile_pic" />)). This was the case regardless of whether or not the end user actually uploaded a file. These days, with so many people browsing the web via iPads, you have to explicitly check to see if the input isset($_FILES['profile_pic']) before calling into it, else you'll get the aforementioned error message. This is because iOS devices running Safari disable file inputs thereby causing them to be treated as if they don't exist. Time to update your scripts!
