안녕하세요~

input type="checkbox" 를 필드값으로 추가하였는데요

수정하러 들어가보니 체크상태가 풀려있습니다~

이럴때는 어떤방법이있나요?

<div class="attr-value">
				<input type="hidden" name="kboard_option_type_chk1" value="">
				<input type="checkbox" name="kboard_option_type_chk1" value='<img src="/wp-content/uploads/detail_kboard/certified_logo_1.jpg" />'<?php if($content->option->type_chk1 == '<img src="/wp-content/uploads/detail_kboard/certified_logo_1.jpg" />'):?> checked<?php endif?>> 우수제품
				<input type="hidden" name="kboard_option_type_chk2" value="">

				<input type="hidden" name="kboard_option_type_chk6" value="">

			</div>

이렇게 진행해보니 제 생각과는 결과값이 다르네요 ..
