Я создаю форму зоны падения с помощью dropzone.js. Когда форма отправляется пустым, форма не выполняется, отправляя на пустой ULR. Как я могу переопределить форму для проверки полей, которые не являются пустыми?Валидация формы Dropzone
Это мой код. Спасибо за помощь.

NEW JS custom.dropzone.js which seems to break the upload.php function
Dropzone.options.myAwesomeDropzone = { // The camelized version of the ID of the form element
// The configuration we've talked about above
autoProcessQueue: false,
parallelUploads: 3,
maxFiles: 3,
previewsContainer: ".dropzone-previews",
accept: function(file, done) {
console.log("uploaded");
done();
},
init: function() {
this.on("maxfilesexceeded", function(file){
alert("No more files please!");
});
},
// The setting up of the dropzone
init: function() {
var myDropzone = this;
// First change the button to actually tell Dropzone to process the queue.
this.element.querySelector("button[type=submit]").addEventListener("click", function(e) {
// Make sure that the form isn't actually being sent.
e.preventDefault();
e.stopPropagation();
myDropzone.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() {
// Gets triggered when the form is actually being sent.
// Hide the success button or the complete form.
});
this.on("successmultiple", function(files, response) {
// Gets triggered when the files have successfully been sent.
// Redirect user or notify of success.
});
this.on("errormultiple", function(files, response) {
// Gets triggered when there was an error sending the files.
// Maybe show form again, and notify user of error
});
}
}
Это метод я использую для ZF2 и DropZone - это кажется слишком сложным, но работает (ну еще нужно обрабатывать удаление файла после того, как удалить доктрина) – dan2k3k4
