使用 Laravel 5 添加用于文件上传的 DropzoneJS

Question

我有一个包含文件上传输入的表单，运行良好，但我想用 DropzoneJS 替换它以添加拖放功能，但所有文件都使用 DropzoneJS 上传。

这是我的观点：

<!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，所以我猜文件没有上传。我错过了什么吗？

好吧，我尝试了 dropzone.js，速度非常快，一切正常。

在查看了您的代码后，我想我解决了您的问题：

在你的route.php你有这个：

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，你看当你想获取文件时必须使用 Request 而不是 Input，Input was used on Laravel 4.2.

只需复制并粘贴此内容并在您的 routes.php

上覆盖您的上传路径

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！如果您想了解更多关于获取表单输入和文件的信息，您应该阅读 Request documentation also since you usually want to validate that input, take a look at Validation documentation
