How do I check with PHP if a file was attached to an HTML form?

I need to make sure that either the text was entered into the form's textarea input element or a file attached through the file input element. I tried various things, including this:

if((empty($_POST['text'])) && (!empty($_FILES['uploadedfile']))) {
            $errors .= 'Please either enter your text or attach a file.<br/><br/>';
        }

Doesn't work.

Thank you!

if ((!empty($_POST['text']) && file_exists($_FILES["image"]["tmp_name"])) || (empty($_POST['text']) && !file_exists($_FILES["image"]["tmp_name"]))) {
    throw new Exception('must choose one or other');
}

this will pass if one is set or the other, but not both and not none.

if($_FILES!=null && $_POST!=null){
    $file = $_FILES["image"]["tmp_name"];

Try

if((empty($_POST['text'])) || (empty($_FILES['uploadedfile']))) {
    errors .= 'Please either enter your text or attach a file.<br/><br/>';
}

You only want one OR the other so you ask if the "text" field is empty OR the "uploadFile" is empty
