我正在编写我的第一个WP短代码，在将我的工作PHP转换为工作短代码时遇到了困难。我已经成功地创建了一个基本的短代码，它可以在我想要的位置返回文本，所以很多都是好的。但我把巧克力放在花生酱里做得不太好。

以下是我对工作PHP的了解：

<div class="authorsocial">
    <h5>Connect, Share &amp; Follow</h5>
        <ul>
           <?php $meta_socialgr = apply_filters(\'the_content\', get_post_meta($post->ID, \'author_goodreads\', true));
              if (!empty($meta_socialgr)) { ?>
                <li><a href="<?php echo get_post_meta( $post->ID, \'author_goodreads\', true );?>"><img src="http://fiddlehead.milkbossindustries.com/files/goodreads.jpg"></a></li>
           <?php } ?>
        </ul>
</div><!-- end authorsocial -->              

下面是我的基本短代码：

<?php
// Adding a shortcode to return each author\'s social media links
    function funcauthor_social( $atts ){
        $output = \'bubbalicious\';
        return $output;
    }
    add_shortcode( \'author_social\', \'funcauthor_social\' );
?>

我在用函数替换“bubbalicious”方面并没有太大成功，因为我只是没有掌握。。。某物

<?php
// Adding a shortcode to return each author\'s social media links
    function funcauthor_social( $atts ){
        $output = \'<div class="authorsocial">
        <h5>Connect, Share &amp; Follow</h5>
        <ul>\'.$meta_socialgr = apply_filters(\'the_content\', get_post_meta($post->ID, \'author_goodreads\', true));
             if (!empty($meta_socialgr)) { \'
             <li><a href="\'.echo get_post_meta( $post->ID, \'author_goodreads\', true );.\'"><img src="http://fiddlehead.milkbossindustries.com/files/goodreads.jpg"></a></li>\'.}.\'
        </ul>
      </div>\';
      return $output;
 }
    add_shortcode( \'author_social\', \'funcauthor_social\' );
    ?>

<?php
// Adding a shortcode to return each author\'s social media links
    function funcauthor_social( $atts ){
        $meta_socialgr = esc_url(get_post_meta( $post->ID, \'author_goodreads\', true ));

        $output = \'<div class="authorsocial"><h5>Connect, Share &amp; Follow</h5><ul>\';

        if (!empty($meta_socialgr)) { 
            $output .= \'<li><a href="\'.$meta_socialgr.\'"><img src="http://fiddlehead.milkbossindustries.com/files/goodreads.jpg"></a></li>\';
          }

         $output .= \'</ul></div>\';

        return $output;
 }
    add_shortcode( \'author_social\', \'funcauthor_social\' );
    ?>
