本文实例讲述了Laravel框架文件上传功能实现方法。分享给大家供大家参考,具体如下:
- 以Laravel 5.2.45 框架为主,进行文件上传功能的实现如下:
实现步骤:
(1). 配置文件修改
打开 config/filesystems.php 文件
在 ‘disks' 数组中添加如下代码

//自定义
'uploads' => [
'driver' => 'local' ,
//'root' => storage_path('app/uploads'),
'root' => public_path( 'uploads/' . date ( 'Ymd' )),
],

(2).前端视图 upload.blade.php
根据需求,设计简单的视图,核心代码如下

< div class = "panel panel-default" >
< div class = "panel-heading" >文件上传</ div >
< div class = "panel-body" >
< form class = "form-horizontal" role = "form" method = "POST" action = "" enctype = "multipart/form-data" >
{{ csrf_field() }}
< div class = "form-group" >
< label for = "file" class = "col-md-4 control-label" >Hello world</ label >
< div class = "col-md-6" >
< input id = "file" type = "file" class = "form-control" name = "source" >
</ div >
</ div >
< div class = "form-group" >
< div class = "col-md-6 col-md-offset-4" >
< button type = "submit" class = "btn btn-primary" >
< i class = "fa fa-btn fa-sign-in" ></ i > 上传
</ button >
</ div >
</ div >
</ form >
</ div >
</ div >

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
//上传文件 功能实现方法
public function upload(Request $request ){
if ( $request ->isMethod( 'POST' )){
$file = $request ->file( 'source' );
//判断文件是否上传成功
if ( $file ->isValid()){
//原文件名
$originalName = $file ->getClientOriginalName();
//扩展名
$ext = $file ->getClientOriginalExtension();
//MimeType
$type = $file ->getClientMimeType();
//临时绝对路径
$realPath = $file ->getRealPath();
$filename = uniqid(). '.' . $ext ;
$bool = Storage::disk( 'uploads' )->put( $filename , file_get_contents ( $realPath ));
//判断是否上传成功
if ( $bool ){
echo 'success' ;
} else {
echo 'fail' ;
}
}
}
return view( 'upload' );
}

(4). 执行上述方法结果
通过调用上述方法,正确执行后,上传的文件将出现在 public/uploads 的对应日期目录下
希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
