利用WordPress短代码给文章添加卡片式内链

首先需要将如下代码放入你主题的函数模板里(functions.php)

    /**
    * 卡片式文章内链功能
    * https://www.yaxi.net/2018-03-20/1741.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));
    $category = get_the_category($ids);
    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 ).'"><span class="embed-card-category">'. $category[0]->cat_name .'</span></a>
    <span class="embed-card-img">
    <a target="_blank" href="' . get_permalink() . '"><img alt="'. get_the_title() . '" src="'. post_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( get_the_excerpt(), 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>人气:</i>'. post_views(false, '', '', false) .'</span>
    <span class="group-data"> <i>评论:</i>'. get_comments_number() .'</span>
    <a target="_blank" href="' . get_permalink() . '"><span class="card-btn-deep">阅读全文</span></a>
    </span>
    </span>
    </span>
    <link rel="stylesheet" href="'. get_template_directory_uri() .'/css/embed-card.css"/>';
    }
    wp_reset_postdata();
    return $content;
    }
    add_shortcode('yx_embed_post', 'yx_embed_posts');

注意:上述代码中有调用自定义的函数(如阅读量,缩略图等),如果读者使用的话需要根据实际情况进行修改,由于大家的主题不统一,没有办法一一描述。

下面参考CSS代码,建议另存为embed-card.css并放入主题根目录的css文件夹中(与上述PHP代码中路径对应)

    .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;
    white-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: right;
    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%;
    }
    }

使用的时候只需要在文章里添加短代码

    [yx_embed_post ids=123,245]

(WordPress文章id查看方法不赘述,多篇文章用,隔开)

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。

    do_shortcode('[yx_embed_post ids=123,245]')
