comment_form() 参数
<?php comment_form($args, $post_id); ?>
$args：comment_form() 的输出配置参数，为一个关联数组，配置项非常丰富，下面我们会详细说明。
$post_id：文章id，默认为空，即当前id
$args的默认配置：
$defaults = array(
'fields' => apply_filters( 'comment_form_default_fields', $fields ),
'comment_field' => '<p class="comment-form-comment"><label for="comment">' . _x( 'Comment', 'noun' ) . '</label><textarea id="comment" name="comment" cols="45" rows="8" aria-required="true"></textarea></p>',
'must_log_in' => '<p class="must-log-in">' . sprintf( __( 'You must be <a href="%s">logged in</a> to post a comment.' ), wp_login_url( apply_filters( 'the_permalink', get_permalink( $post_id ) ) ) ) . '</p>',
'logged_in_as' => '<p class="logged-in-as">' . sprintf( __( 'Logged in as <a href="%1$s">%2$s</a>. <a href="%3$s" title="Log out of this account">Log out?</a>' ), admin_url( 'profile.php' ), $user_identity, wp_logout_url( apply_filters( 'the_permalink', get_permalink( $post_id ) ) ) ) . '</p>',
'comment_notes_before' => '<p class="comment-notes">' . __( 'Your email address will not be published.' ) . ( $req ? $required_text : '' ) . '</p>',
'comment_notes_after' => '<p class="form-allowed-tags">' . sprintf( __( 'You may use these <abbr title="HyperText Markup Language">HTML</abbr> tags and attributes: %s' ), ' <code>' . allowed_tags() . '</code>' ) . '</p>',
'id_form' => 'commentform',
'id_submit' => 'submit',
'title_reply' => __( 'Leave a Reply' ),
'title_reply_to' => __( 'Leave a Reply to %s' ),
'cancel_reply_link' => __( 'Cancel reply' ),
'label_submit' => __( 'Post Comment' ),
);

add_filter('comment_form_default_fields', 'mytheme_remove_url');
function mytheme_remove_url($arg) {
$arg['url'] = '';
return $arg;
}

function my_fields($fields) {
$fields['qq'] = '<p class="comment-form-qq">' . '<label for="qq">'.__('QQ').'</label> ' .
'<input id="qq" name="qq" type="text" value="' . esc_attr( $commenter['comment_qq'] ) . '" size="30" /></p>';
return $fields;
}
add_filter('comment_form_default_fields','my_fields');

$fields = array(
'author' => '<p class="comment-form-author">' . '<label for="author">' . __( 'Name' ) . '</label> ' . ( $req ? '<span class="required">*</span>' : '' ) .
'<input id="author" name="author" type="text" value="' . esc_attr( $commenter['comment_author'] ) . '" size="30"' . $aria_req . ' /></p>',

'url' => '<p class="comment-form-url"><label for="url">' . __( 'Website' ) . '</label>' .
'<input id="url" name="url" type="text" value="' . esc_attr( $commenter['comment_author_url'] ) . '" size="30" /></p>',
);

function add_my_tips() {
echo '欢迎踊跃发言！';
}
// 在默认字段（前面说的姓名、邮箱和网址）的下面添加字段
add_filter('comment_form_after_fields', 'add_my_tips');
// 在已登录下面添加字段（因为用户登录后，是没有默认上面三个字段的），所以要使用这个钩子插入内容
add_filter('comment_form_logged_in_after', 'add_my_tips');
