How to get modal bootstrap data and send to PHP

I need to get Modal form data via Ajax My code:

var url = 'fotovisita.php';
var data = $('#foto').serialize();
var type = "POST";

$(document).on('click', '#save-foto', function () {
    $.ajax({
        url: url,
        method: 'POST',
        data: data,
        contentType: 'application/json',

        beforeSend: function () {
            $('#save-foto').val("Saving");
        },
        success: function (data) {
            $('#foto')[0].reset();
            $('#cadastraFoto').modal('hide');
            console.log(data)
            //$('#call sucess message').html(data); 
        }
    });
});

My Modal

<div class="container">
<!-- MODAL FOTO -->

<div id="cadastraFoto" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="cadastraFotoLabel" aria-hidden="true" style="display: none;">
    <div class="modal-dialog" role="document">

                            <button type="button"  name="save-foto" id="save-foto" class="btn btn-primary">
                                <span class="fas fa-plus"></span>
                                Salvar</button> 
                        </div>
                    </div>

                </form>
            </div>
        </div><!-- /.modal-content -->
    </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
<!-- fim modal foto -->

My goal is to get all typed fields and send them to the PHP page editacli.php that already has the methods to receive the $ _POST ['']; of each form element and do the save saving in the database and then I want to close the Modal and display a message on the Modal screen, "Data saved successfully".

But this Ajax code is not working, when I click the button on the page that receives the data via $ _POST, it is not returning the form data.
