添加DropzoneJS以使用Laravel 5上传文件 [英] Add DropzoneJS for file upload with Laravel 5
问题描述
我有一个文件上传输入正常的表单，但是我想用DropzoneJS替换它以添加拖放功能，但是任何文件都可以通过DropzoneJS上传.
I have a form with files uploading input that is working well but I want replace it with DropzoneJS to add drag and drop functionality but any files get uploaded with DropzoneJS.
我的想法如下:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Testing DropzoneJS with Laravel 5</title>
<script src="{{ asset('js/dropzone.js') }}"></script>
<link rel="stylesheet" href="{{ asset('css/dropzone.min.css') }}">
</head>
<body>
<div class="container">
<form class="form-horizontal dropzone dz-clickable" action="{{url('/upload)}}" method="post" enctype="multipart/form-data">
<!-- Name input-->
<input id="name" name="name" type="text" placeholder="Your Name" class="form-control">
<div class="dz-message" id="my-dropzone">
<h4>Drag Photos to Upload</h4>
<span>Or click to browse</span>
</div>
<!-- Token -->
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
<!-- Form actions -->
<button type="submit" class="btn btn-primary btn-lg">Add</button>
</form>
</div>
</body>
</html>
我的路线文件:
Route::post('/upload', function(){
$the_new_product->name = Input::get('name');
$the_new_product_picture = Input::file('file');
return dd($the_new_product_picture); // I get Null as respons
});
我得到Null作为响应，所以我猜该文件没有上传. 我想念什么吗?
I get Null as respons, so I guess the file is not uploaded. Am I missing something?
推荐答案
好吧，我尝试了dropzone.js，运行速度很快，而且一切正常.
Well I tried dropzone.js and it was was blazing fast and everything worked fine.
在看完您的代码后，我想我已经解决了您的问题:
And after looking at your code, I think I figured out your problem:
在您的 route.php 上，您拥有以下内容:
On your route.php you have this:
Route::post('/upload', function(){
$the_new_product->name = Input::get('name');
$the_new_product_picture = Input::file('file');
return dd($the_new_product_picture); // I get Null as respons
});
这是错误的，您看到要提取文件时必须使用请求而不是输入，输入已在Laravel 4.2上使用.
This is wrong, you see when you want to fetch a file you must use Request not Input, Input was used on Laravel 4.2.
只需复制并粘贴该文件，然后在您的 routes.php
Just copy and paste this and overwrite your upload route on your routes.php
Route::post('/upload', function () {
//check if file was uploaded
if (Request::hasFile('file'))
{
//houston we have a file!
$file = Request::file('file');
//move it to our public folder and rename it to $name
Request::file('file')->move('images', 'insert_file_name.'.$file->getClientOriginalExtension());
echo 'file uploaded!';
var_dump($file);
}else{
echo 'no file, no bueno';
}
});
就是这样！如果您想了解有关获取表单输入和文件的更多信息，还应该阅读请求文档，因为通常要验证该输入，请查看验证文档
And that's it! If you want to read more about getting form inputs and files you should read the Request documentation also since you usually want to validate that input, take a look at Validation documentation
这是我的观点:
