jquery file upload check box additional form

Bonjour,

Pour mon site j'utilise jquery file upload (https://github.com/blueimp/jQuery-File-Upload/) et j'essaie d'ajouter 2 variables (la valeur false ou true des checkbox) à mon .fileupload.

Le soucis étant que je débute en JS et j'ai du mal.

J'ai vu ça :

https://github.com/blueimp/jQuery-File-Upload/wiki/How-to-submit-additional-form-data

J'ai donc ajouté un "FormData" à mon fileupload cependant la valeur qui est récupérée et envoyée est la valeur de base lors du chargement de la page (false).

Voici mon code html :

<input id="fileupload" style="display:none;" type="file" name="files[]" multiple>

<input type="checkbox" id="guest" name="guest" value="1">

<input type="checkbox" id="signed" name="signed" value="1">

$(function() {
    "use strict";
    var e = $("<button/>").addClass("intimity-button-dark").prop("disabled", !0).text("Processing...").on("click", function() {
        var param1 = $('#guest').is("checked");
        console.log(param1);
        var e = $(this),a = e.data();
        e.off("click").text("Abort").on("click", function() {
            e.remove(), a.abort()
        }), a.submit().always(function() {
            e.remove()
        })
    });
    $("#fileupload").fileupload({
        url: "/server/php/",
        dataType: "json",
        autoUpload: !1,
        acceptFileTypes: /(\.|\/)(gif|jpe?g|png|mov|mp4|avi)$/i,
        maxFileSize: 5e6,
        disableImageResize: /Android(?!.*Chrome)|Opera/.test(window.navigator.userAgent),
        previewMaxWidth: 200,
        previewMaxHeight: 300,
        formData: {guest: $("#guest").prop('checked'), signed : $("#signed").prop('checked')},
        previewCrop: !0
    }).on("fileuploadadd", function(a, n) {
        n.context = $("<div/>").addClass('col-xs-6 col-sm-4').appendTo("#files"), $.each(n.files, function(a, t) {
            var r = $("<p/>").append($("<span/>").text(t.name));
            a || r.append("<br>").append(e.clone(!0).data(n)), r.appendTo(n.context)
        })
    }).on("fileuploadprocessalways", function(e, a) {
        var n = a.index,
            t = a.files[n],
            r = $(a.context.children()[n]);
        t.preview && r.prepend("<br>").prepend(t.preview), t.error && r.append("<br>").append($('<span class="text-danger"/>').text(t.error)), n + 1 === a.files.length && a.context.find("button").text("Upload").prop("disabled", !!a.files.error)
    }).on("fileuploadprogressall", function(e, a) {
        var n = parseInt(a.loaded / a.total * 100, 10);
        $("#progress .progress-bar").css("width", n + "%")
    }).on("fileuploaddone", function(e, a) {
        $.each(a.result.files, function(e, n) {
            if (n.url) {
                var t = $("<a>").attr("target", "_blank").prop("href", n.url);
                $(a.context.children()[e]).wrap(t)
            } else if (n.error) {
                var r = $('<span class="text-danger"/>').text(n.error);
                $(a.context.children()[e]).append("<br>").append(r)
            }
        })
    }).on("fileuploadfail", function(e, a) {
        $.each(a.files, function(e) {
            var n = $('<span class="text-danger"/>').text("File upload failed.");
            $(a.context.children()[e]).append("<br>").append(n)
        })
    }).prop("disabled", !$.support.fileInput).parent().addClass($.support.fileInput ? void 0 : "disabled")
});
</script>

Tout ce passe ici :

formData: {guest: $("#guest").prop('checked'), signed : $("#signed").prop('checked')},

J'ai essayé avec un .is(':checked') mais toujours le même résultat.

J'imagine que la raison est simple, le fileupload (qui permet de configurer le "Jquery file upload" dans sa globalité) et la valeur des checkbox assigné aux deux checkbox sera la valeur de mes checkbox lors du chargement de la page.

Je ne sais pas trop comment faire, à l'aide !

Merci !
