【中文标题】如何在 laravel 上上传文件并将其存储在目录中【英文标题】：How to upload files on laravel and storing it in a directory 【发布时间】：2021-08-30 22:09:38 【问题描述】：所以我在将我的用户图片存储在指定目录中时遇到了问题。图像已经在数据库中，但是当我调用数据时它没有显示任何内容。我如何将它存储在公用文件夹中，这里的数据库是我的代码行：
RegisterController.php
<?php
namespace App\Http\Controllers;
use Hash;
use App\Models\User;
use Illuminate\Http\Request;
class RegisterController extends Controller
public function signin()
return view('register', [
'register' => true
]);
public function register(Request $request)
// Laravel Eloquent
$user = User::where('email', $request->get('email'))->first();
if ($user)
// if user / email exists
return view('register', [
'register' => false
]);
else
// create user
User::create([
'name' => $request->get('name'),
'email' => $request->get('email'),
'password' => Hash::make($request->get('password')),
'user_type' => 'admin',
'bdate' => $request->get('bdate'),
'contact_no' => '',
'profile_image' => $request->file('profile_image')->store('http://localhost:8000/storage/images/'),
//...
]);
return redirect(route('login.login', ['registration' => 1]));
这是注册表

【问题讨论】：
数据库工作正常我不知道如何将它存储在laravel框架中的特定文件夹中 【参考方案1】：你可以使用Storage:: 类来做到这一点
'profile_image' => $request->file('profile_image') ? Storage::disk('public')->put('images',$request->profile_image) : null
然后它将在数据库中存储路径以获取该文件的完整 URL，您可以再次使用 Storage::url()
喜欢
$url = \Storage::disk('public')->url($user->profile_image)
您需要像这样将enctype 添加到您的表单标签中
<form class="user" method="POST" action=" route('register.register') " enctype="multipart/form-data">
参考链接https://laravel.com/docs/8.x/filesystem
【讨论】：
表示该列不能为空 哦那你需要上传profile_image添加所需的验证
如果没有存储任何内容，我将 null 更改为默认图片，当我上传图片时它似乎没有保存在数据库中
语句有效，但是路径不存储在数据库中
这里是错误 Illuminate\Database\QueryException SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'profile_image' cannot be null (SQL: insert into users (name, email ，password，user_type，bdate，contact_no，profile_image，updated_at，created_at）的值（123，123 @ 123 $ 2Y $ 10 $ D84jMeksPiwOWwkIsPeYl.TUEsYPq54Oxu2xqv1bCMyYK4GlKfsPa，管理员，2021-06 -02, 123, ?, 2021-06-15 05:35:17, 2021-06-15 05:35:17)) 127.0.0.1:8000/register以上是关于如何在 laravel 上上传文件并将其存储在目录中的主要内容，如果未能解决你的问题，请参考以下文章
