如何自定义WordPress短代码功能，通过shortcode获取每个类别的帖子变量？

Question

我使用下面的代码来创建一个WordPress简码[educationposts]来显示名为“education”的类别的帖子。

如何设置这个简码功能是灵活的，因为可以通过改变这样的[帖=教育]简码或[帖=博客]

感谢

/*** show post category ***/ 
function pwp_postsbycategory() { 
$the_query = new WP_Query(array('category_name' => 'education', 'posts_per_page' => 5)); 

if ($the_query->have_posts()) { 
    $string .= '<ul class="postsbycategory widget_recent_entries">'; 
    while ($the_query->have_posts()) { 
     $the_query->the_post(); 
     if (has_post_thumbnail()) { 
      $string .= '<li>'; 
      $string .= '<a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_post_thumbnail($post_id, array(75, 75)) . get_the_title() .'</a></li>'; 
     } else { 
      // if no featured image is found 
      $string .= '<li><a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_title() .'</a></li>'; 
     } 
    } 
} else { 
    // no posts found 
} 
$string .= '</ul>'; 

return $string; 

/* Restore original Post Data */ 
wp_reset_postdata(); 
} 
// Add a shortcode 
add_shortcode('educationposts', 'pwp_postsbycategory'); 
/*** show post category ***/

我解决它通过表现出任何类别设置$ atts in函数。

/*** show post category ***/ 
function pwp_postsbycategory($atts) { 
$the_query = new WP_Query(array('category_name' => $atts['cat'], 'posts_per_page' => 5)); 

if ($the_query->have_posts()) { 
    $string .= '<ul class="postsbycategory widget_recent_entries">'; 
    while ($the_query->have_posts()) { 
     $the_query->the_post(); 
     if (has_post_thumbnail()) { 
      $string .= '<li>'; 
      $string .= '<a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_post_thumbnail($post_id, array(75, 75)) . get_the_title() .'</a></li>'; 
     } else { 
      // if no featured image is found 
      $string .= '<li><a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_title() .'</a></li>'; 
     } 
    } 
} else { 
    // no posts found 
} 
$string .= '</ul>'; 

return $string; 

/* Restore original Post Data */ 
wp_reset_postdata(); 
} 
// Add a shortcode 
add_shortcode('posts', 'pwp_postsbycategory'); 
/*** show post category ***/
