HTML/PHP File Upload

Question

So i want the user to only be able to upload docs or docx\'s. So first here\'s my html:

Answer 1

Your file field name is img and you have used $_FILES["file"], but it should be $_FILES["img"].

Also you need to change your if condition

if (($_FILES["file"]["size"] < 200000)
    && in_array($extension, $allowedExts)) {

There is no need of

$extension!=".doc" || $extension!=".doc" &&
