Saya tidak boleh mendapatkan PHP untuk membaca teks yang dihantar melalui Ajax.

Apabila saya mengklik butang, saya mendapat mesej Menghantar data daripada Ajax , peluncur tidak menunjukkan ralat, tetapi teks dalam div di mana PHP sepatutnya membaca Siaran menunjukkan ralat:

Anda perlu menghantar data sebagai objek. Seperti ini: 

$.ajax({
    type: 'POST',
    url: '//localhost/slider/modal.php',
    data: {data: 'Test shipping'},
}).done(function() {
    alert('data sent');
});
