Laravel 5.2 File Upload Feature usage example

Configuration

File system configuration file in config/filesystems.php file, here we create a new uploads local disk space for storing uploaded files, specific configuration items and descriptions as follows:

<?php

return [

/*
|--------------------------------------------------------------------------
| Default filesystem Disk
|--------------------------------------------------------------------------
|
| Here/May specify the default filesystem disk that should to be used
| By the framework. A "local" driver, as a variety of cloud
| Based drivers are available for your choosing. Just Store away!
|
| Supported: "Local", "FTP", "S3", "Rackspace"
|
*/

The default use of local-side space supports "locals", "ftp", "S3", "Rackspace"
' Default ' => ' local ',

/*
|--------------------------------------------------------------------------
| Default Cloud filesystem Disk
|--------------------------------------------------------------------------
|
| Many applications store files both locally and in the cloud. For this
| Reason, you could specify a default "cloud" Driver here. This driver
| would be bound as the Cloud disk implementation in the container.
|
*/

Cloud storage using Amazon S3
' Cloud ' => ' S3 ',

/*
|--------------------------------------------------------------------------
| FileSystem disks
|--------------------------------------------------------------------------
|
| This is configure as many filesystem "disks" as you wish, and
| May even configure multiple disks of the same driver. Defaults have
| been setup for each driver as a example of the required options.
|
*/

' Disks ' => [

Local-side space
' Local ' => [
' Driver ' => ' local ',
' Root ' => storage_path (' app '),
],

Public space on the local side
' Public ' => [
' Driver ' => ' local ',
' Root ' => storage_path (' App/public '),
' Visibility ' => ' public ',
],

Create a new local-side uploads space (directory) for storing uploaded files
' Uploads ' => [

' Driver ' => ' local ',

Files will be uploaded to the storage/app/uploads directory
' Root ' => storage_path (' app/uploads '),

Files will be uploaded to the public/uploads directory if the browser requires direct access please set this
' Root ' => public_path (' uploads '),
],

Amazon S3 Related Configuration
' S3 ' => [
' Driver ' => ' S3 ',
' Key ' => ' Your-key ',
' Secret ' => ' Your-secret ',
' Region ' => ' your-region ',
' Bucket ' => ' your-bucket ',
],

],

];

Third, code implementation file upload

1. Controller code

<?php

namespace App\http\controllers;

Use Illuminate\http\request;
Use Storage;
Use app\http\requests;

Class Filecontroller extends Controller
{

File Upload Method
Public function upload (Request $request)
{

if ($request->ismethod (' post ')) {

$file = $request->file (' picture ');

Whether the file was uploaded successfully
if ($file->isvalid ()) {

               //Get file-related information
                $originalName = $file- >getclientoriginalname (); File formerly known as
                $ext = $ File->getclientoriginalextension ();    //EXTENSION
                 $realPath = $file->getrealpath ();  // Absolute path of temporary file
                $type = $ File->getclientmimetype ();    //Image/jpeg

Uploading files
$filename = Date (' Y-m-d-h-i-s '). '-' . Uniqid (). '.' . $ext;
Use our new uploads local storage space (directory)
$bool = Storage::d ISK (' uploads ')->put ($filename, file_get_contents ($realPath));
Var_dump ($bool);

}

}

Return view (' upload ');
}
}

2. The most basic upload.blade.php template code:

<form method= "POST" enctype= "Multipart/form-data" >   
    <input type = "File" name= "picture"
    <button type= "Submit" > Submit </button>
</form>
When you get to a file, you can perform various processing of the file. If it is a picture, you can do a variety of scaling and cropping operations.
