我已创建搜索。php来自二十一主题搜索模板。搜索模板工作正常，但当未找到任何结果时，我遇到了一个问题
我收到了这个PHP通知：通知：尝试获取非对象wp includes/post模板的属性。php第29行
帖子模板第29行如下所示：
function get_the_ID() {
return get_post()->ID;<-this is the source of the problem
}
我假设这是因为
get_post()->ID 未设置（当未显示结果时），因为我在搜索模板中输入了以下代码：
<?php if ( !isset ($post->ID)) {
echo \'not set\';<- this will echo "not set" if NO results are found and
PHP notice will be displayed:(
}
else{
echo \'set\';<- this will echo "set" if results ARE found and
PHP notice will NOT be displayed
}
?>
所以我的问题是如何设置
$post->ID （如果未设置）以删除PHP通知
非常感谢您的帮助，谢谢！！
搜索php代码：
<?php
get_header(); ?>
<?php get_sidebar(); ?>
<?php get_sidebar(\'secondary\'); ?>
<?php if ( !isset ($post->ID )) {
echo \'not set\';
}
else{
echo \'set\';
}
?>

看来我的问题不是搜索。php，但我的页脚。php此代码导致错误<?php post_comments_feed_link( $link_text = \'Comments RSS\', $post_id = \'post_id\', $feed = \'rss2\' ); ?> 无论如何，我的页脚代码如下所示：
<div id="footer">
<?php wp_footer(); ?>
<p>

</p>
<p><a href="<?php bloginfo(\'rss2_url\'); ?>">Latest Stories RSS</a> |
<?php post_comments_feed_link( $link_text = \'Comments RSS\', $post_id = \'post_id\', $feed = \'rss2\' ); ?></p>
</div>
</div><!--/wrapper-->
我使用@Svetlana Silina对其进行了修改，回答如下：
<div id="footer">
<?php wp_footer(); ?>
<p>
<strong>Copyright 2013 <?php bloginfo(\'name\'); ?> | All Rights Reserved.</strong>

</p>
<p><a href="<?php bloginfo(\'rss2_url\'); ?>">Latest Stories RSS</a> |
<?php if(get_post()){
?>
<?php post_comments_feed_link( $link_text = \'Comments RSS\', $post_id = \'post_id\', $feed = \'rss2\' ); ?></p>
<?php } else if(!get_post()){
?>
<?php post_comments_feed_link( $link_text = \'Comments RSS\', $post_id = \'1\', $feed = \'rss2\' ); ?></p>
<?php } ?>
</div>
现在一切都很好，没有PHP通知，即使没有显示结果。生活又好了：=）
