本文介绍了PHP学习:利用laravel+ajax实现文件上传功能方法示例,希望对您有用。如果有疑问,可以联系我们。
前言
大家都知道,早期的XMLHttpRequest不支持文件上传,一般用第三方js插件或者flash,现在可以借助XMLHttpRequest Level 2 的FormData对象实现二进制文件上传,正好最近工作中遇到了这个需求,所以本文就来给大家总结下实现的方法,话不多说了,来一起看看详细的介绍吧.
示例代码
@extends('layouts.art') @section('content') <form class="form-horizontal" id="avatar"> {{ csrf_field() }} <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">名字</label> <div class="col-sm-8"> <input type="title" class="form-control" id="title" name="title"> </div> </div> <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">头像</label> <div class="col-sm-8"> <input type="file" class="form-control" id="title" name="photo"> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <a class="btn btn-default" onclick="uploadInfo()">上传</a> </div> </div> </form> <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script> <script type="text/javascript"> function uploadInfo() { var formData = new FormData($("#avatar")); $.ajax({ url: "{{url('photo')}}", type: 'POST', data: formData, contentType: false, processData: false, success: function (returndata) { console.log(returndata); }, error: function (returndata) { console.log(returndata); } }); } </script> @endsection
//生成路径,图片存储 $ext = $request->photo->getClientOriginalExtension(); $cover_path = "images/album/covers/" . time() . $ext; $name = "photo".time(); $src = "images/album/photos/". $name .".jpg"; Image::make($request->photo)->save(public_path($src));*/ //批量上传图片 foreach ($request->photo as $key => $value) { //生成路径,图片存储 $prefix = "photo".mt_rand(1,1000); $Origname = $value->getClientOriginalName(); $name = $prefix.$Origname; $src = "images/album/photos/".$name; $realPath = $value->getRealPath(); Storage::disk('uploads')->put($src,file_get_contents($realPath)); }
