Wenn ich FormData mit JSON/Ajax einreiche, geht es nicht durch [geschlossen] ⇐ Php

[Anonymous]

Ich versuche, meinen Benutzern ein Profilfoto hinzuzufügen, aber wenn ich versuche, auf die Schaltfläche Senden zu klicken, wird es nicht durchläuft.
function getUserFormData(form) {
return {
action: "addUser",
user: {
user_id: User : null,
email: form['email'].value,
username: form['username'].value,
password: Util.hash(form['password'].value),
password_confirmation: Util.hash(form['password_confirmation'].value),
profile_image: form['profile_image'].value
}
};
}

AS.Http.submituser = function (form, data, success, error, complete) {
AS.Util.removeErrorMessages();

var $submitBtn = $(form).find("button[type=submit]");
var $fileupload = $(data).prop('profile_image');
var formData = new FormData();
formData.append('file', $fileupload);

if ($submitBtn) {
AS.Util.loadingButton($submitBtn, $submitBtn.data('loading-text') || $_lang.working);
}

$.ajax({
url: "/Ajax.php",
cache: false,
contentType: false,
processData: false,
type: "POST",
dataType: "json",
data: data,
success: function (response) {
form.reset();

if (typeof success === "function") {
success(response);
}
},
error: error || function (errorResponse) {
AS.Util.showFormErrors(form, errorResponse);
},
complete: complete || function () {
if ($submitBtn) {
AS.Util.removeLoadingButton($submitBtn);
}
}
});
};

Ich habe versucht, Datei anzuhängen, aber leider passiert immer noch nichts. Ich kann nicht sehen, was Fehler ist, weil es nicht angezeigt wird.>
