【问题描述】：
以下函数通过将其添加到 >the_content() 来工作，但是，我想通过自定义标记在我的 html 标记中的自定义位置显示它，当我尝试这个时，我得到了一个 PHP 错误，我确定这是非常简单的事情，但我一生都看不到这个问题。
// code from crunchify
function supersun_social_sharing_buttons($content) {
global $post;
if(is_singular() || is_home()){
// Get current page URL
$supersunURL = urlencode(get_permalink());
// Get current page title
$supersunTitle = str_replace( ' ', '%20', get_the_title());
// Get Post Thumbnail for pinterest
$supersunThumbnail = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );
// Construct sharing URL without using any script
$twitterURL = 'https://twitter.com/intent/tweet?text='.$supersunTitle.'&url='.$supersunURL.'&via=Crunchify';
$facebookURL = 'https://www.facebook.com/sharer/sharer.php?u='.$supersunURL;
$googleURL = 'https://plus.google.com/share?url='.$supersunURL;
$whatsappURL = 'whatsapp://send?text='.$supersunTitle . ' ' . $supersunURL;
$pinterestURL = 'https://pinterest.com/pin/create/button/?url='.$supersunURL.'&media='.$supersunThumbnail[0].'&description='.$supersunTitle;
// Add sharing button at the end of page/page content
$variable .= '<div class="supersun-social">';
$variable .= '<a class="supersun-social-link supersun-twitter" href="'. $twitterURL .'" target="_blank" title="Share on Twitter"><i class="fa fa-twitter" aria-hidden="true"></i></a>';
$variable .= '<a class="supersun-social-link supersun-facebook" href="'.$facebookURL.'" target="_blank" title="Share on Facebook"><i class="fa fa-facebook" aria-hidden="true"></i></a>';
$variable .= '<a class="supersun-social-link supersun-whatsapp" href="'.$whatsappURL.'" target="_blank" title="Share on Whatsapp"><i class="fa fa-whatsapp" aria-hidden="true"></i></a>';
$variable .= '<a class="supersun-social-link supersun-googleplus" href="'.$googleURL.'" target="_blank" title="Share on Google+"><i class="fa fa-google-plus" aria-hidden="true"></i></a>';
$variable .= '<a class="supersun-social-link supersun-pinterest" href="'.$pinterestURL.'" target="_blank" title="Share on Pinterest"><i class="fa fa-pinterest" aria-hidden="true"></i></a>';
$variable .= '</div>';
return $variable.$content;
}else{
// if not a post/page then don't include sharing button
return $variable.$content;
}
};
add_filter( 'the_content', 'supersun_social_sharing_buttons');
添加时出现此错误消息
<?php supersun_social_sharing_buttons(); ?>
到我的主题。
非常感谢您抽出宝贵时间。抱歉，该网站目前还没有上线，我认为这对于有经验的人来说应该是一个简单的解决方案。

你能读懂你得到的错误吗？它说什么？ “失踪……”？
-
是的，请原谅我的经验不足，我不完全确定这意味着什么？任何帮助将不胜感激。
