员工控制器

<?php
namespace AppHttpControllers;
use AppTalentEmployeeRequestsEmployeeCreateRequest;
use AppTalentEmployeeEmployeeManager;
use IlluminateHttpResponse;
use AppTalentUserUserManager;
use AppTalentDocumentsDocumentManager;
use IlluminateSupportFacadesHash;

class EmployeeController extends Controller
{
public function __construct(private EmployeeManager $employeeManager,private UserManager $userManager,private DocumentManager $documentManager)
{
}
public function store(EmployeeCreateRequest $request){
$validated = $request->validated();
$userArray=[
'name'=>$validated['first_name']." ".$validated['last_name'],
'email'=>$validated['email'],
'password'=>Hash::make("Introcept@123"),
'role'=>'user'
];
$userCreate=$this->userManager->store($userArray);
return $this->employeeStore($validated,$userCreate,$request);
}
public function employeeStore($validated,$userCreate,$request){
if($request->hasFile($validated['avatar']))
{
$validated['avatar']=$validated['avatar']->store('employeeimages','public');
}
else
{
$validated['avatar']='null';
}
$userId=$userCreate->id;
$userIdArray=[
'user_id'=>$userId,
'status'=>'Active',
];
$employeeArray=array_merge($validated,$userIdArray);
$employeeCreate=$this->employeeManager->store($employeeArray);
$employeeId=$employeeCreate->id;
foreach($validated['documents'] as $document){
$name=$document->getClientOriginalName();
$type=$document->getClientMimeType();
$path=$document->store('employeedocuments','public');
$documentArray=[
'employee_id'=>$employeeId,
'original_name'=>$name,

$documentCreate=$this->documentManager->store($documentArray);
}

return response([
'userId'=>$userId,
'employeeId'=>$employeeId,
'message'=>'Personal detail added successfully',
],Response::HTTP_OK);
}
}

Employee.php

<?php

namespace AppTalentEmployeeModel;
use AppTalentDocumentsModelDocument;
use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Employee extends Model
{
use HasFactory;

protected $fillable = [
'first_name',
'last_name',
'email',
'contact_number',
'date_of_birth',
'current_address',
'pan_number',
'bank_account_number',
'avatar',
'status',
'user_id',
];

**EmployeeRequest.php**
<?php
namespace AppTalentEmployeeRequests;
use IlluminateFoundationHttpFormRequest;
class EmployeeCreateRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array<string, mixed>
*/
public function rules()
{
return [
'first_name'=>'required|string',
'last_name'=>'required|string',
'email'=>'required|email|unique:employees,email',
'contact_number'=>'required|string',
'date_of_birth'=>'required|date',
'current_address'=>'required|string',
'pan_number'=>'string|nullable',
'bank_account_number'=>'string|nullable',
'avatar' => 'nullable|image|mimes:jpg,jpeg,png',
'documents'=>'required',
'documents.*'=>'max:5000|mimes:pdf,png,jpg,jpeg',
];
}
public function messages()
{
return [
'documents.max' => "Error uploading file:File too big.Max file size:5MB",
];
}
}

员工迁移

<?php
use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateSupportFacadesSchema;
return new class extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('employees', function (Blueprint $table) {
$table->id();
$table->foreignId('user_id')->constrained('users')->restrictOnDelete();
$table->string('status');
$table->string('first_name');
$table->string('last_name');
$table->string('email')->unique();
$table->string('contact_number');
$table->date('date_of_birth');
$table->string('current_address');
$table->string('pan_number')->nullable();
$table->string('bank_account_number')->nullable();
$table->string('avatar')->nullable();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('employees');
}
};

我正在尝试创建一个API，将员工的个人详细信息存储到数据库中。在这里，图像字段是可选的，所以我在迁移和验证请求中都使化身字段为空。但当我尝试在不上传图像的情况下将详细信息保存到数据库中时，它会显示未定义的化身。我不知道这里发生了什么，任何帮助或建议都将不胜感激。非常感谢。

您使用的字符串值为null，而不是关键字null。
