如何从存储方法中获取上载的图像名称 [英] How to get the uploaded image name from the store method

问题描述

当我通过以下方式将图像存储在Laravel中时:

When I store an image in Laravel by doing:

$path = $request->file('myImage')->store('public/src/');

它返回完整路径，但是我如何只获得给定的文件名?

It returns the full path, but how do I get only the filename it was given?

这是返回路径的示例:

public/src/ltX4COwEmvxVqX4Lol81qfJZuPTrQO6S2jsicuyp.png

推荐答案

在Laravel中，store()方法动态生成名称..所以您不能从store()方法中获取它.

In Laravel, the store() method generates the name dynamically .. so you can't get it from the store() method.

但是您可以使用storeAs()方法.基本上store()方法正在调用storeAs()方法.所以:

But you can use storeAs() method. Basically the store() method is calling the storeAs() method. So:

$path = $request->file('myImage')->store('public/src');

Laravel在做什么，正在调用->storeAs('public/src', $request->file('myImage')->hashName()); ..您看到了hashName()方法吗?就是这个名字的产生.

What Laravel is doing is calling ->storeAs('public/src', $request->file('myImage')->hashName()); .. you see the hashName() method? that is what generates the name.

因此，您可以先致电hashName()并在存储发生之前知道您的名字..这是一个示例:

So you can call hashName() first and know your name before the storing happens .. here is an example:

$uploadFile = $request->file('myImage');
$file_name = $uploadFile->hashName();
$path = $uploadFile->storeAs('public/src', $file_name);

现在您有$file_name和$path.
