php – 我可以使用Dropzone提交表单而无需上传任何文件吗？

我遵循了Combine Dropzone With Normal Form教程,允许Dropzone上传和放大表格提交.表格是申请表格,应该与&没有添加文件.目前,仅当将一个或多个文件添加到Dropzone时,它才有效.

是否有一个选项我可以允许Dropzone处理表单提交,即使上传队列为空？

以下是我初始化表单的方法：

                Dropzone.options.general = {
                paramName: 'tx_ddapplicationform_applicationformgeneral[form][files]', // The name that will be used to transfer the file
                autoProcessQueue: false,
                uploadMultiple: true,
                parallelUploads: 100,
                maxFiles: 100,
                addRemoveLinks: true,
                previewsContainer: '.dropzone-previews', // we specify on which div id we must show the files
                clickable: false,


                // The setting up of the dropzone
                init: function() {
                    var myDropzone = this;
                    console.log(myDropzone)
                    console.log("Dropzone init");

                    console.log(this.element.querySelector("input[type=submit]"))

                    // First change the button to actually tell Dropzone to process the queue.
                   this.element.querySelector("input[type=submit]").addEventListener("click", function(e) {
                        // Make sure that the form isn't actually being sent.
                        console.log("the button is clicked")
                        e.preventDefault();
                        e.stopPropagation();
                        myDropzone.processQueue();
                        console.log("after processQueue")
                    });

                    // Listen to the sendingmultiple event. In this case, it's the sendingmultiple event instead
                    // of the sending event because uploadMultiple is set to true.
                   this.on("sendingmultiple", function() {
                        console.log("sending multiple");
                    });
                    this.on("successmultiple", function(files, response) {
                        console.log("success multiple");
                    });
                    this.on("errormultiple", function(files, response) {
                        console.log("error multiple");
                    });
                }

我浏览了dropzone.js表单并添加了console.logs来查看发生了什么.成功提交(添加了文件)记录下：

 processQueue dropzone.js:1301
 upload multiple dropzone.js:1314
 sending multiple main.jquery.js:551
 after processQueue main.jquery.js:545
 success multiple main.jquery.js:554

没有附加文件的不成功提交会记录下：

 processQueue dropzone.js:1301
 after processQueue main.jquery.js:545

解决方法:

好吧,可能是一个死灵帖子,但是因为我在谷歌结果页面的第一个链接中发现了这个问题,并且因为它被观看了很多,我认为答案不会伤害任何人.

我有相同的结构,并解决我刚才做的问题：

$('#my-dropzone input[type="submit"]').on('click', function(
    // Make sure that the form isn't actually being sent.
    e.preventDefault();
    e.stopPropagation();
    if (myDropzone.files.length) {
        myDropzone.processQueue(); // upload files and submit the form
    } else {
        $('#my-dropzone').submit(); // just submit the form
    }
});

请注意,如果您使用dropzone(第一种情况)提交表单,则通过ajax执行此操作,因此结果应由返回的响应处理,而如果您只提交表单(第二种情况),则您将获得正常的表单提交.

在我的情况下,这需要基于提交类型的不同响应.
