Laravel - 从上传的文件中获取大小

Question

提问by lewis4u

I have saved a file with this command

我用这个命令保存了一个文件

$newFile = [
            'event_id' => $event->id,
            'path' => $storePath
           ];

EventFile::create($newFile);

I can get the path to the file for a link like this:

我可以获得文件的路径以获取这样的链接：

Storage::disk('public')->url($file->path);

But there is no data about the file size. How can i get the file size in blade view???

但是没有关于文件大小的数据。如何在刀片视图中获取文件大小？？？

Answer 1

Laravel 5

$request->file('file')->getSize();

Laravel 4

$request->file('file')->getClientSize(); // getClientSize() is deprecated in Laravel 5

Answer 2

getClientSize() is deprecated starting version 4.1. Use getSize() instead.

Answer 3

Very simple(Proper Laravel Way):

非常简单（正确的 Laravel 方式）：

//add this at the top of your controller
use File;

// add this with in your function
$size = File::size($PATH_OF_FILE);

Answer 4

The more Simpler way is to use Storage Facadeif you have already stored / uploaded file

Storage Facade如果您已经存储/上传文件，则更简单的方法是使用

use Illuminate\Support\Facades\Storage;

public function get_size($file_path)
{
    return Storage::size($file_path);
}

Or if you are using S3Bucket then you can modify the above function like below

或者，如果您使用的是S3Bucket，那么您可以像下面一样修改上述功能

use Illuminate\Support\Facades\Storage;

public function get_size($file_path)
{
    return Storage::disk('s3')->size($file_path);
}
