인터넷 서핑을 하다보면 대부분의 블로그에 댓글 남기는 칸이 있다.

댓글 템플릿 만들고 single.php에 적용까지 시켜보자.

comments.php 파일 만들기

<?php
	$comment_send = '등록';
	$comment_reply = '댓글';
	$comment_reply_to = '답글';

	$comment_author = '이름';
	$comment_email = 'E-Mail';
	$comment_body = '댓글을 남겨주세요.';
	$comment_cookies_1 = '개인 정보 보호 정책';
	$comment_cookies_2 = '에 동의합니다.';

	$comment_before = '';
	$comment_after = '';

	$comment_cancel = '답글 취소';

	if ( post_password_required() )
	{
		return;
	}

?>
<?php
	$comments_args = array
	(
		'fields' => array
		(
			'author' => '<p class="comment-form-author"><br /><input id="author" name="author" aria-required="true" placeholder="' . $comment_author .'"></input></p>',
			'email' => '<p class="comment-form-email"><br /><input id="email" name="email" placeholder="' . $comment_email .'"></input></p>',
			'cookies' => '<input type="checkbox" required> <a href="' . get_privacy_policy_url() . '">' . $comment_cookies_1 . '</a>'  . $comment_cookies_2,
		),

		'label_submit' => __( $comment_send ),
		'title_reply' => __( $comment_reply ),
		'title_reply_to' => __( $comment_reply_to ),

		'comment_notes_after' => __( $comment_after),
		'id_submit' => __( 'comment-submit' ),
	);

	comment_form( $comments_args );
?>
		<div class="comment-list">
<?php
			wp_list_comments(
				array(
					'style'			=> 'div',
					'short_ping'	=> true,
				)
			);
?>
		</div>

single.php에 적용
