comment_form_title()
云策文档标注
概述
comment_form_title() 函数用于根据评论回复状态显示文本,主要影响禁用 JavaScript 的用户。它通常用于 comment_form() 函数下方和评论表单之前。
关键要点
- 函数根据是否回复评论显示不同文本,默认无回复时显示“Leave a Reply”,回复时显示“Leave a Reply to %s”。
- 参数包括 $no_reply_text(无回复文本)、$reply_text(回复文本,可包含 %s 占位符)、$link_to_parent(是否将作者名链接到评论)和 $post(指定文章)。
- 内部依赖全局变量 $comment,以确保模板标签能访问当前评论。
- 函数行为受 $_GET['replytocom'] 影响,通过 _get_comment_reply_id() 获取回复 ID。
代码示例
function comment_form_title( $no_reply_text = false, $reply_text = false, $link_to_parent = true, $post = null ) {
global $comment;
if ( false === $no_reply_text ) {
$no_reply_text = __( 'Leave a Reply' );
}
if ( false === $reply_text ) {
/* translators: %s: Author of the comment being replied to. */
$reply_text = __( 'Leave a Reply to %s' );
}
$post = get_post( $post );
if ( ! $post ) {
echo $no_reply_text;
return;
}
$reply_to_id = _get_comment_reply_id( $post->ID );
if ( 0 === $reply_to_id ) {
echo $no_reply_text;
return;
}
// Sets the global so that template tags can be used in the comment form.
$comment = get_comment( $reply_to_id );
if ( $link_to_parent ) {
$comment_author = sprintf(
'%2$s',
get_comment_ID(),
get_comment_author( $reply_to_id )
);
} else {
$comment_author = get_comment_author( $reply_to_id );
}
printf( $reply_text, $comment_author );
}注意事项
- 此函数仅对禁用 JavaScript 或未加载 comment-reply.js 的页面有效。
- 在 WordPress 6.2.0 版本中新增了 $post 参数,允许指定文章。
- 使用时需确保全局 $comment 变量已设置,以便模板标签正常工作。
