Issue With Sending Image Over Ajax

I created a on submit function that grabs different data along with images, if the user has uploaded them and ties the images into a FormData type object. This is than sent along

Solution 1:

You cannot just add a FormData object as a property to the data object. You can only send one FormData object alone, which will get encoded appropriately. If you pass a key-value object, jQuery will try to www-form-urlencode that. See also How to send FormData objects with Ajax-requests in jQuery?.

ElevationColorsForm.prototype.submit = function() {
    if (!window.FormData) {
        alert("Sorry, your browser does not support uploading files with Ajax.");
        throw new Error("no FormData support");
    }

    function getValue() { return this.value; }

    var formdata = new FormData();

    var color_name = $(".color-item-input").map(getValue).get().join(", ");
    var RestrictionSelectActive = $(".restriction_active_ability option:selected").map(getValue).get();
    var color_type = $(".color-item").map(function() {           
        if ($(this).hasClass('current-color'))
            return 'current-color';
        if ($(this).hasClass('new_color'))
            return 'new-color';
        return '';
    }).get();

    $(".color-item-file").each(function() {
        if(this.files.length > 0 && /image.*/.test(this.files[0].type)) {
             formdata.append("images[]", this.files[0]);
        } else {
            formdata.append("images[]", 'none');
        }
    });

    formdata.append('elevation_id', this.Elevation.data.ifpe_id);
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    $.ajax({
        url: "actions/save_elevation_colors.php",
        type: "post",
        data: formdata,
//            ^^^^^^^^
        processData: false,
        contentType: false
    }).then(function(data){
        console.log(data);
        $(".message_box").text("Changes made!");
        $(".message_box").fadeIn(); 
        setTimeout(function(){
            $(".message_box").fadeOut();
            $(".message_box").empty();  
        },2000);
    }, function(){
        alert("failure");
    });
}
