Given by POST method uploads

Be sure your file upload form has attribute enctype="multipart/form-data" otherwise the file upload will not work.

Your current solution lacks enctype, that's why your file is not getting uploaded to the server and therefore isn't in the superglobal variable $_FILES.

As ferikeem already said. Wrap your data in a FormData Object and send it that way. See: https://stackoverflow.com/a/5976031/10887013

JavaScript

let fd = new FormData();
fd.append("you_file_key_here", $("#upimage")[0].files[0]);
fd.append("data1", $("#data1")[0].value);
fd.append("data2", $("#data2")[0].value);
fd.append("data3", $("#data3")[0].value);

$.ajax({
    url: "././newregister.php",
    method: "POST",
    data: fd,
    processData: false,
    contentType: false,
    success: function(data){
        alert(data);
    }
});

$_FILES["file"], here is your problem.

In $_FILES array key "file" doesn't exists. As I see you need to change $_FILES["file"] with $_FILES["upimage"].
