发布的文章多了，免不了有些文章沾亲带故的，为了翻遍阅读，需要在当前文章中插入另外一篇文章的链接。默认转化的链接不好看，而PIX主题又不提供卡片式链接的功能，我们只有自己改造了。

一、演示：

二、将以下代码放到PIX主题下的functions.php或func.php中。

// 获取特色图片地址
function jsk_the_thumbnail_src() {
  global $post;
    if ( get_post_meta($post->ID, 'thumbnail', true) ) { //如果有缩略图，则显示缩略图
      $image = get_post_meta($post->ID, 'thumbnail', true);
        return $image;
    } else {
      if ( has_post_thumbnail() ) { //如果有缩略图，则显示缩略图
        $img_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "Full");
        return $img_src[0];      
        } else {
            return get_template_directory_uri().'/img/thumbnail.png'; //文章中没有图片就设置默认图片
        }
    }
}
/*卡片式文章内链功能*/
function pix_posts( $atts, $content = null ){
extract( shortcode_atts( array(
'ids' => ''
),
$atts ) );
global $post;
$content = '';
$postids = explode(',', $ids);
$inset_posts = get_posts(array('post__in'=>$postids));
$category = get_the_category();
foreach ($inset_posts as $key => $post) {
setup_postdata( $post );
$content .= '<span class="embed-card">
<span class="embed-card-img">
<a target="_blank" href="' . get_permalink() . '"><img alt="'. get_the_title() . '" src="'. jsk_the_thumbnail_src() .'"></a>
</span>
<span class="embed-card-info">
<a target="_blank" href="' . get_permalink() . '">
<span class="card-name">'. get_the_title() . '</span>
</a>
<span class="card-abstract">'.wp_trim_words( $post->post_content, 100, '...' ).'</span>
<span class="card-controls">
<span class="group-data"> <i>时间:</i>'. get_the_time('Y/n/j') .'</span>
<span class="group-data"> <i>分类:</i><a target="_blank" href="'.get_category_link($category[0]->term_id ).'">'. $category[0]->cat_name .'</a></span>
</span>
</span>
</span>
<link rel="stylesheet" href="'. get_template_directory_uri() .'/inc/assets/css/embed-card.css"/>';
}
wp_reset_postdata();
return $content;
}
add_shortcode('pix_post', 'pix_posts');

三、在pix/inc/assets/css下新建UTF8格式的文件embed-card.css，写入以下代码：

.embed-card,span.embed-card {
display: block;
position: relative;
width: 620px;
padding: 9px;
margin: 30px auto;
border: 1px dashed #d4d4d4;
overflow: hidden;
max-width: 90%;
}
.embed-card:hover,span.embed-card:hover {
box-shadow: 1px 1px 8px #eee;
}
.embed-card a,span.embed-card a {
padding-right: 0;
text-decoration: none;
color: #313131;
}
.embed-card span,span.embed-card span {
display: block;
padding-right: 0;
}
.embed-card-category {
display: inline-block;
height: 20px;
line-height: 20px;
padding: 0 5px;
font-size: 12px;
}
.embed-card-category {
background-color: #6a99d8;
background-color: rgba(43,110,200,0.8);
color: #fff;
}
.embed-card-category:hover {
background-color: #d5e2f4;
background-color: rgba(43,110,200,1);
}
.embed-card .embed-card-category {
position: absolute;
top: 9px;
left: 0;
padding-right: 5px;
}
.embed-card-img {
float: left;
margin-right: 14px;
}
.embed-card-img img {
width: 180px;
height: 150px;
}
.embed-card-info {
padding-right: 4px;
overflow: hidden;
}
.embed-card-info .card-name {
font-size: 16px;
height: 44px;
line-height: 22px;
margin-bottom: 10px;
margin-top: 7px;
overflow: hidden;
text-overflow: ellipsis;
whitewhite-space: normal;
font-weight: bold;
}
.embed-card-info .card-tags {
height: 20px;
overflow: hidden;
}
.embed-card-info .card-tags>span {
display: inline-block;
padding: 0 7px;
margin-right: 8px;
height: 16px;
border: 1px solid #eee;
line-height: 16px;
color: #999;
font-size: 12px;
}
.embed-card-info .card-tags span.tag-noborder {
border: 0;
}
.embed-card-info .card-abstract {
height: 36px;
line-height: 18px;
margin: 5px 0;
font-size: 12px;
color: #666;
overflow: hidden;
margin-bottom: 20px;
}
.embed-card-info .card-controls {
overflow: hidden;
line-height: 28px;
}
.embed-card-info .card-controls .group-data {
float: left;
margin-right: 10px;
color: #999;
font-size: 12px;
}
.embed-card-info .card-controls .group-data i {
margin-right: 5px;
font-style: normal!important;
}
.embed-card-info .card-btn-deep {
float: rightright;
width: 68px;
height: 28px;
margin-left: 10px;
line-height: 28px;
text-align: center;
font-size: 12px;
background-color: #ff5e5c;
color: #fff;
}
.embed-card-info .card-btn-deep:hover {
opacity: .9;
}
@media only screen and (max-width:700px) {
span.embed-card {
width: 95%;
padding-left: 0;
padding-right: 0;
}
.embed-card .embed-card-img {
width: 24.27184%;
margin-left: 9px;
}
.embed-card .embed-card-img img {
width: 100%;
height: auto;
}
.embed-card .embed-card-info {
overflow: visible;
padding: 0 9px;
}
.embed-card .embed-card-info .card-name {
margin-top: 1%;
margin-bottom: 1.5%;
}
}

大功告成！
