我正在使用Laravel 5.5，我希望我的用户在注册时上传个人资料图片，以便它的路径将存储在'images'表中，其中包含image_id，image_path和我希望{的值{1}}同时存储在image id表中。
任何人都可以帮我做。

$user->images()->save($image);快捷方式：users
associating的文档。
所以我们有一个简单的Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password')->nullable();
$table->rememberToken();
$table->timestamps();
});
表：
user_images我们有一个simlpe Schema::create('user_images', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user_id')->nullable(); // user id
$table->string('file')->unique(); // File path
$table->boolean('is_index')->default(false); // is it profile picture? you can call this whatever you want
$table->softDeletes(); // 'deleted_at' column for archive
$table->timestamps();
});
表：
User <?php
namespace App;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable,
SoftDeletes;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name',
'email',
'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password',
'remember_token',
];
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = [
'deleted_at',
];
/**
* Get the images for the user.
*
* @return \Illuminate\Database\Eloquent\Relations\HasMany
*/
public function images()
{
return $this->hasMany(UserImage::class);
}
}
型号：
UserImage <?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class UserImage extends Model
{
use SoftDeletes;
/**
* All of the relationships to be touched.
*
* @var array
*/
protected $touches = ['user'];
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'user_id',
'file',
'is_index'
];
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = [
'deleted_at'
];
/**
* Get the user that owns the image.
*
* @return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function user()
{
return $this->belongsTo(User::class);
}
}
模型：
User::find(1)->images;
这就是用户拥有多张图片的方式。
如果要在控制器中检索用户所有图像：
$user = User::find(1);
foreach($user->images as $images) {
echo $user->file;
}
例如：
UserImage您可以为public function scopeAvatar($query)
{
$query->where('is_index', '=', '1')->first();
}
// Usage:
$user->image->avatar->file // Only the profile picture
模型添加范围，以便更轻松地获取个人资料照片
