Uploading File Annoying Error

Question

I have been trying to research why this issue continues to come up. I am getting the error:

Notice: Undefined index: file in C:\xampp2\htdocs\Onboarding\OnBoarding\test.php on line 7
Notice: Undefined index: file in C:\xampp2\htdocs\Onboarding\OnBoarding\test.php on line 9

Now I know what these mean...basically the array is empty and it is Undefined. How do I prevent this from showing? Here is my very simple code:

<form method="POST" action="test.php" enctype="multipart/form-data">
<input type="file" name="file" /> <br /> <br />
<input type="submit" value="Submit" /> 
</form>

<?php
$name = $_FILES['file']['name'];
$tmp_name = $_FILES['file']['tmp_name'];

if(isset($name)){
    if(!empty($name)){
        $location = "files/application_other/";

        if (move_uploaded_file($tmp_name, $location.$name));
        echo "Uploaded!";
    } else {
        echo "Please choose a file";
    }
}
?>

The file does upload properly, I just cant figure out how to remove the error messages.

Thank you for the help in advance.

You must check whether the array contains the given key, before accessing it.

if (array_key_exists('file', $_FILES)) {
  $name = $_FILES['file']['name'];
}
