wordpress美化文章内链采用卡片模式展示推荐文章代码分享

采用短代码给文章添加卡片式内链，通过get_posts自定义调用文章的标题、发布时间等内容，直接以html的形式在前台加载，在一定程度上提高了用户体验，实际

效果如图：

演示如下

[yx_embed_post ids=2371]

开始食用啦

将一下代码复制到functions.php中即可。
注：模板不同，有些会是在：(functions-theme.php)只要是全局调用文件就可以啦（例如本站主题就是）

一、将如下代码放入你主题的函数模板里（functions.php）或(functions-theme.php)

精简代码

（去除了红色按钮，将按钮文字颜色进行更改，取消显示评论数量）

/**
* 卡片式文章内链功能
* https://www.ly522.com/2379.html
*/
function yx_embed_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 );
$content .= '<span class="embed-card">
<a target="_blank" href="'.get_category_link($category[0]->term_id ).'"></a>
<span class="embed-card-img">
</span>
<span class="embed-card-info">

</span>

<link rel="stylesheet" href="'. get_template_directory_uri() .'/embed-card.css"/>';
}
wp_reset_postdata();
return $content;
}
add_shortcode('yx_embed_post', 'yx_embed_posts');

调用文章方法

使用的时候只需要在文章里添加短代码即可
单文章/123为文章ID

[yx_emb删除ed_post 删除ids=123]

多文章/ 采用 ，号隔开就好

[yx_embe删除d_post 删除ids=123,234]

如果你不是在文章内容中，而是在其他地方想调用，则可使用下面代码来调用。
【123,234】为文章ID 记得修改

do_short删除code(‘[yx_embe删除d_post 删除ids=123,234]’)

记得把代码中的删除去掉
快速获取文章ID方法

文章调用word press直接在编辑文章时选择文本在合适位置放置调用代码即可
