我正在使用dropzone.js。我有一个表单,单击提交按钮时提交输入和图像。但是,当我返回其中一个输入(不是图像)错误的错误时,error
事件也会显示图像有错误,即使它没有。
例如,如果其中一个输入为空且表单返回错误并显示消息"请填写表单",上传的图像将(错误地)也有错误,并且此更改为HTML:
<div class="dz-error-message"><span data-dz-errormessage="">[object Object]</span></div>
实际返回的错误(注意图像没有错误):
{"success":"false","messages":{"message":["The message field is required."]}}
我的问题是,如何修改我的代码以识别返回的错误是图像错误还是表单输入错误?
这是我的JS:
Dropzone.options.formPost = {
autoProcessQueue: false,
uploadMultiple: true,
parallelUploads: 25,
maxFiles: 25,
maxFilesize: 5,
acceptedFiles: "image/*",
clickable: "#image-upload",
init: function() {
var myDropzone = this;
var form = $("#form-post");
this.element.querySelector('button[type="submit"]').addEventListener("click", function(e)
{
e.preventDefault();
e.stopPropagation();
myDropzone.processQueue();
});
this.on("addedfile", function()
{
// some stuff
});
this.on("sendingmultiple", function()
{
// some stuff
});
this.on("successmultiple", function(files, response)
{
// some stuff
});
this.on("errormultiple", function(files, response)
{
// if an error is return, even though it has nothing to do with the image, it will show that the image has an error
$.each(response.messages, function(key, value)
{
form.find('.form-group#' + key).addClass('has-error');
form.find('.form-group#' + key + ' .form-error').html(value[0]).fadeIn();
});
});
}
}
PHP(Laravel):
public function createPost()
{
$rules = array(
'message' => 'required',
);
$validator = Validator::make(Input::except('file'), $rules);
if ($validator->fails())
{
return Response::json(array(
'success' => 'false',
'messages' => $validator->messages()
), 400);
}
else
{
$post = new Post;
$post->user_id = getUserID();
$post->message = Input::get('message');
$post->ip_address = getUserIP();
$post->save();
$files = Input::file('file');
if ($files)
{
/**
* Create a new directory for the post images.
*/
File::makeDirectory(public_path() . '/uploads/posts/' . $post->id, 0775);
foreach ($files as $file)
{
$file_rules = array('file' => 'image|max:5000');
$validator = Validator::make(array('file' => $file), $file_rules);
if ($validator->fails())
{
return Response::json(array(
'success' => 'false',
'messages' => $validator->messages()
), 400);
}
else
{
$ext = $file->getClientOriginalExtension();
$dest = public_path() . '/uploads/posts/' . $post->id . '/';
$file_name = str_random(6);
$upload_success = $file->move($dest, $file_name . '.' . $ext);
if (!$upload_success)
{
return Response::json(array(
'success' => 'false',
), 400);
}
}
}
}
return Response::json(array(
'success' => 'true'
), 200);
}
}

以下代码可能会对图像字段进行更改,但不应该这样做。
form.find('.form-group#whatever')
您可以在浏览器的JS控制台中手动检查form.find('.form-group#whatever')
是否实际上能够指向正确的元素。也许execute()
指向所有输入元素,这会导致问题。
查看HTML代码也很有帮助。
