            {{-- 关键：添加 name="name" 属性 --}}
            <input type="text" class="form-control" value="{{ old('name', auth()->user()->name) }}" id="inputName" name="name" placeholder="Name">
            @error('name')<span class="text-danger">{{ $message }}</span>@enderror

            <textarea class="form-control" id="inputEducation" name="education" placeholder="Education">{{ old('education', auth()->user()->education) }}</textarea>
            @error('education')<span class="text-danger">{{ $message }}</span>@enderror
