在Laravel注册中上传个人资料图片失败

Question

我想在注册时上传个人资料照片

在我必须注册用户之前，我可以将默认的user.jpg更改为我自己的个人资料图片

但现在我想在注册时上传我的个人资料照片

这是我想要上传图片的视图的一部分：

<div class="form-group col-md-12">
                <label>Firmenlogo</label>
                <div class="custom-file">
                    <input type="file" name="avatar" class="custom-file-input" id="validatedCustomFile" required>
                    <input type="hidden" name="_token" value="{{csrf_token()}}">
                    <label class="custom-file-label" for="validatedCustomFile">Datei auswählen...</label>
                    <div class="invalid-feedback">Bitte laden Sie hier Ihr Firmenlogo hoch.</div>
                </div>
            </div>

这是我的控制器：

<?php
namespace App\Http\Controllers\Auth;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{

use RegistersUsers;

protected $redirectTo = '/admin';

public function __construct()
{
    $this->middleware('guest');
}

protected function validator(array $data)
{
    return Validator::make($data, [
        'name' => 'required|string|max:255',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required|string|min:6|confirmed',
        'avatar' => 'required|string',
    ]);
}

protected function create(array $data)
{
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => Hash::make($data['password']),
        'avatar' => $avatar,
    ]);
}

}

这是我的迁移文件：

<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('avatar')->default('default.jpg');
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }
    return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

这是我的user.php

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;
    protected $fillable = [
        'name', 'email', 'password', 'avatar',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];
}

一切正常它将图片保存为我的数据库中的字符串，如picture.jpg但它不保存在我的uploads文件夹中，所以我试试这个：

$avatar = $data['avatar']->file('avatar');
    $filename = time() . '.' . $avatar->getClientOriginalExtension();
    Image::make($avatar)->resize(300, 300)->save(public_path('/uploads/avatars/'.$filename));

但没有发生它没有在我的数据库保存任何东西，如果我点击注册页面重新加载没有任何反应我不知道为什么，我不知道该怎么办我尝试了这么多的东西，阅读了这么多的博客，但没有任何作用

只有在我转到我的个人资料并上传新图片后才能在注册后使用

但为什么？？所以我知道代码工作，但为什么不在寄存器控制器？

Answer 1

首先检查你的表单是否有enctype =“multipart / form-data”并检查你的App \ User.php的$ fillable数组包含数组中的'avatar'键，以便将你的图像插入数据库。

Answer 2

我想你正在寻找这个：

protected function create(Request $request)
{
    if($request->hasFile('avatar')) {

        $avatar = $request->file('avatar');
        $filename = time() . '.' . $avatar->getClientOriginalExtension();
        Image::make($avatar)->resize(300, 300)->save(public_path('/uploads/avatars/'.$filename));
        $avatarPath = '/uploads/avatars/'.$filename;

        $user = new User;
        $user->name = $request['name'];
        $user->email = $request['email'];
        $user->password = Hash::make($request['password']);
        $user->avatar = $avatarPath;
        $user->save();

        return redirect()->back(); /** or somewhere else **/
    }

}

Answer 3

我知道了！这么蠢的事!!!!!!

protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
            'avatar' => 'required',
     ]);
    }

在这个功能我有头像需要和STRING和我删除后一切正常!!!! OMG现在很高兴

这是我现在的创建功能：

 protected function create(array $data)
{
    $request = app('request');
    if($request->hasfile('avatar')){
        $avatar = $request->file('avatar');
        $filename = time() . '.' . $avatar->getClientOriginalExtension();
        Image::make($avatar)->resize(300, 300)->save( public_path('/uploads/avatars/' . $filename) );
    }
    return User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => Hash::make($data['password']),
        'avatar' => $filename,
    ]);
}
