Question

以下功能通过将其添加到＆gt; the_content（）来工作，但是，我希望通过自定义标记将其显示在我的html标记中的自定义位置，当我尝试这个时我得到了一个PHP错误，我是确定这是非常简单的事情，但我为我的生活看不到问题。

  // 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.'&amp;url='.$supersunURL.'&amp;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.'&amp;media='.$supersunThumbnail[0].'&amp;description='.$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');

我添加时出现此错误消息 <?php supersun_social_sharing_buttons(); ?> 我的主题。

非常感谢你的时间。对不起，该网站目前不在线，我认为对于有经验的人来说这应该是一个简单的解决方法。

您需要在直接调用函数时传递参数，而不是add_filter。像这样<?php supersun_social_sharing_buttons($parameter); ?>

WordPress-调用函数 - 使用自定义标记
