Question

function magazine_vertical($atts){
    extract(shortcode_atts(array(
        'slug' => '',
        'title' => '',
        'limit' => '5',
    ),$atts));

    //The Query
    query_posts('showposts=1&orderby=date&order=DESC&category_name='.$slug);

    //The Loop
    if ( have_posts() ) : while ( have_posts() ) : the_post();
        $return .= '<div class="magazine-vertical">';
        $return .= '<div class="magazine-vertical-title-category"><span class="magazine-vertical-title">'.$title.'</span><span class="magazine-vertical-category"><a href="'. get_term_by('slug', $slug, 'category').'">More articles</a></span></div>';
        $return .= '<div class="magazine-vertical-large">';
        $return .= '<div class="magazine-vertical-large-1">';
        $return .= '<div class="magazine-vertical-large-thumbnail">';
        $return .= '<a href="'.get_permalink($post->ID).'" title="">'.get_the_post_thumbnail( $post_id, 'magazine-vertical').'</a>';
        $return .= '</div>';
        $return .= '<div class="magazine-vertical-large-subtitle">';
        $return .= '<a href="'.get_permalink($post->ID).'" title="">'.get_the_title().'</a>';
        $return .= '</div>';
        $return .= '<div class="magazine-vertical-large-date">';
        $return .= get_the_time('F j, Y');
        $return .= '</div>';
        $return .= '<div class="magazine-vertical-large-excerpt">';
        $return .= get_the_excerpt();
        $return .= '</div>';
        $return .= '</div>';
        $return .= '</div>';
    endwhile;
    endif;

    //Reset Query
    wp_reset_query();

    return $return;
}
add_shortcode('magazine_vertical', 'magazine_vertical');

上面的函数产生：Catchable fatal error: Object of class stdClass could not be converted

问题出在这一部分：

$return .= '<div class="magazine-vertical-title-category"><span class="magazine-
vertical-title">'.$title.'</span>
<span class="magazine-vertical-category"><a href="'. get_term_by('slug', $slug, 'category').'">More articles</a></span></div>';

无法使用此代码（我需要此部分包含“更多文章”）：

<a href="'. get_term_by('slug', $slug, 'category').'">More articles</a>

[magazine_vertical slug = my-category]是我在页面内使用的短代码。我把它全部搞定了，除了这部分我必须从slug atts获得类别链接。

在Wordpress中， $ output：Constant OBJECT，ARRAY_A或ARRAY_N

  function get_term_by($field, $value, $taxonomy, $output = OBJECT, $filter = 'raw') { }

默认输出为object，您无法将对象转换为字符串。

您可以尝试get_term_link( $term, $taxonomy );参考：http://codex.wordpress.org/Function_Reference/get_term_link
