아래의 코드를 찾아주세요.

<a href="<?php echo $url->getDocumentURLWithUID($content->uid)?>" title="<?php echo esc_attr(wp_strip_all_tags($content->title))?>">
...
</a>

위 코드의 아래 부분에 아래의 코드를 입력해보시겠어요?

<form method="post" action="<?php echo $url->set('uid', $content->uid)->set('mod', 'order')->toString()?>">
	<input type="hidden" name="<?php echo $order->getItemFieldName($content->uid, 'uid')?>" value="<?php echo $content->uid?>">
	<input type="hidden" name="<?php echo $order->getItemFieldName($content->uid, 'title')?>" value="<?php echo $content->title?>">
	<input type="hidden" name="<?php echo $order->getItemFieldName($content->uid, 'price')?>" value="<?php echo floatval($content->option->price)?>">
	<?php if(kboard_first_contents_mall_is_use_point_order($board) && $content->option->reward_point):?>
	<input type="hidden" name="<?php echo $order->getItemFieldName($content->uid, 'reward_point')?>" value="<?php echo floatval($content->option->reward_point)?>">
	<?php endif?>
	<input type="hidden" name="<?php echo $order->getItemFieldName($content->uid, 'quantity')?>" value="1">
	<div class="kboard-document-detail-button">
		<?php if(kboard_first_contents_mall_is_downloadable()):?>
			<?php if($content->isAttached()):?>
				<?php foreach($content->attach as $key=>$attach):?>
				<button type="button" class="kboard-first-contents-mall-button-action" onclick="window.location.href='<?php echo $url->getDownloadURLWithAttach($content->uid, $key)?>'" title="<?php echo sprintf(__('Download %s', 'kboard'), $attach[1])?>"><i class="fas fa-download"></i> <?php echo $attach[1]?></button>
				<?php endforeach?>
			<?php endif?>
		<?php elseif($board->isOrder()):?>
			<?php if(kboard_first_contents_mall_is_current_user_order($board)):?>
				<button type="submit" class="kboard-first-contents-mall-button-order"><?php echo __('Buy It Now', 'kboard')?></button>
			<?php else:?>
				<a href="<?php echo wp_login_url($_SERVER['REQUEST_URI'])?>" class="kboard-first-contents-mall-button-order" onclick="return confirm('구매하기 위해서는 먼저 로그인해야 합니다. 로그인 페이지로 이동할까요?');"><?php echo __('Buy It Now', 'kboard')?></a>
			<?php endif?>
		<?php else:?>
			<?php echo __('Sold Out', 'kboard')?>
		<?php endif?>
	</div>
</form>

위 코드의 form 태그는 document.php 파일 내에 있습니다.

고맙습니다.
