Why form serialize does not work in this case?

Question

I have a form which I wanna send via AJAX so I'll use serialize jQuery function.

This is the code (not all the elements has "name", but anyway the alert should display something):

JS

$('#add-producto').click(function (e) {

    alert($('#datos-add').serialize())

    $.ajax({
        type: "POST",
        url: "insertar.php",
        data: $('#datos-add').serialize(),
        success: function (data) {
            alert(data);
        }
    });


    e.preventDefault();

});

HTML

</form>

Do you see what I'm doing wrong?

Any tip, advide or help will be appreciated, and if you need more info, let me know and I'll edit the post.

Answer 1

Your form id is "datos-añadir" but your JavaScript refers to "datos-add".

Here is a jsfiddle fork that works. All I did was fix the reference:

$('#add-producto').click(function (e) {

    var $form = $('#datos-añadir');
    alert($form.serialize());
    return false;

Answer 2

Fist of all, there is a typo. It should be <form id="datos-add"> instead of <form id="#datos-add">.

But I also think you are serializing it the wrong way.

When you do a POST ajax call, you shoud use .serializeArray(), instead of .serialize().

The .serialize() will join all key/values like a query string. The .serializeArray() will include all key/values in the request.

In short, try:

$('#add-producto').click(function (e) {
    $.ajax({
        type: "POST",
        url: "insertar.php",
        data: $('#datos-add').serializeArray(),
        success: function (data) {
            alert(data);
        }
    });
    e.preventDefault();
});
