如何将功能正常的图片上传按钮添加到现有表单？
我正在尝试将图像上传到预先存在的表单，但是在提交表单时出现错误 SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value。
我已经设法让表单上的实际按钮和文件选择器起作用，但是，在提交时它会引用上述错误。关于这个问题的任何帮助或资源都会很棒。
后控制器
<?php
namespace App\Http\Controllers;
use App\Post;
use Illuminate\Http\Request;
class PostController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response

public function index()
{
$posts = Post::all();
return view('post.index', compact('posts'));
}
/**

public function create()
{
$post = new Post();
return view('post.create', compact ('post'));
}
/**

$data = request()->validate([
'title' => 'required',
'body' => 'required',

$post = \App\Post::create($data);
return redirect('/posts');

我认为默认情况下 user_id 没有默认值。在您的帖子模型中，protected $fillable = ['user_id', 'title', 'body', 'image'];同样在您的商店功能中，您必须包括来自当前登录用户的用户。 use App\Post; use Auth; public function store(Request $request) { $request->validate([ 'title' => 'required', 'body' => 'required', ]); $post = new Post(); $post->user_id = Auth::user()->id; $post->title = $request->title; $post->body = $request->body; $post->save(); return redirect('/posts'); }
