bootstrap-fileinput文件上传组件和laravel引用(未完)

前言：之前的三篇介绍了下bootstrap table的一些常见用法，发现博主对这种扁平化的风格有点着迷了。前两天做一个excel导入的功能，前端使用原始的input type='file'这种标签，效果不忍直视，于是博主下定决心要找一个好看的上传组件换掉它。既然bootstrap开源，那么社区肯定有很多关于它的组件，肯定也有这种常见的上传组件吧。经过一番查找，功夫不负有心人，还是被博主找到了这个组件：bootstrap fileinput。关于这个组件的简单应用，博客园大牛伍华聪写过一篇基于Metronic的Bootstrap开发框架经验总结（5）--Bootstrap文件上传插件File Input的使用，只不过很多细节都没有涉及，于是博主在完成开发任务之余，总结了下这个组件的一些常见用法。在此记录下，就算做个笔记吧，也给需要使用的朋友提供点方便。

 安装：composer

$ php composer.phar require kartik-v/bootstrap-fileinput "dev-master"
或
$ composer require kartik-v/bootstrap-fileinput "dev-master"

当然也可以，在github上下载发布版，引入文件~~

Html页面（laravel表单提交必须token）所以

头部要加入：

<meta name="csrf-token" content="{{ csrf_token() }}">

上传表达这样写：

<form enctype="multipart/form-data" method="post">
       <label class="control-label">Select File</label>
       <input id="input-b5" name="input-b5[]" type="file" multiple>
          {{ csrf_field() }}
</form>



<script>

    $(document).ready(function(){
        $("#input-b5").fileinput({
            showCaption: false,
            theme: 'fa',
            language: 'zh',
            uploadUrl: './upload',
            allowedFileExtensions: ['jpg', 'png', 'gif']
        });
    });
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        }
    });

</script>

控制器简单的写下：

class ReportController  extends Controller
{//报表处理类
    public function ReportUpload()
    {
        return view('admins/report/reportupload');

    }
    public function upload(Request $request)
    {
        $data = $request->all();
        dd($data);
    }

}

 

结果：
