【问题标题】：How To Include Only Chosen Posts (by id) - Wordpress Shortcode如何仅包含选择的帖子（按 id）-Wordpress 简码
【发布时间】：2015-01-01 00:30:59
【问题描述】：

此简码显示我主页上的最后 X 个帖子（从最新到最旧排序）。我想选择我想按 ID 显示的那些。怎么做？

我有一个类似这样的简码

这是输入：

if(!empty($blog)){
        echo do_shortcode('[blog item_number=4]'); 
           }

这是此短代码的代码。

function beau_blog($atts, $content = null, $code = '')
{
  
    global $imgsize;

    extract(shortcode_atts(array(
        'post_not_in' => '',
        'item_number' => '4',
	
    ), $atts));
    $loop = new WP_Query('&posts_per_page=' . $item_number);
    ?>
    <section class="beau-blog stretch-layout">
        <div class="blog-title"><?php echo get_post_meta(get_the_ID(), '_page_blog_text', TRUE); ?></div>
        <div class="blog-content"><?php echo get_post_meta(get_the_ID(), '_page_blog_des', TRUE); ?></div>
        <?php if ($loop->have_posts()) : ?>
            <div class="blog-lists">
                <?php $i = 0;
                while ($loop->have_posts()) : $loop->the_post();
                    $featuredID = wp_get_attachment_image_src(get_post_thumbnail_id(), 'single-post-thumbnail');
                    $date = strtotime( get_the_date() );
                    if ($i % 2 != 0) {
                        ?>
                        <div class="row-fluid">

【解决方案1】：

改变你的功能 beau_blog() 如下只有最初的几行，其他的和它一样

function beau_blog($atts, $content = null, $code = '')
{

    global $imgsize;

    extract(shortcode_atts(array(
        'post_not_in' => '',
        'post_in' => '', //you cannoot use post__not_in and post__in in same query so you have to use either one of that. I've modified it to give priority to post_in so if that argument is empty then only the post_not_in ids are used to exclude those posts.
        'item_number' => '4',

    ), $atts));
    if(empty($post_in)){
        $loop = new WP_Query('&posts_per_page=' . $item_number.'&post__not_in='.$post_not_in);
        }
    else{
        $loop = new WP_Query('&posts_per_page=' . $item_number.'&post__in='.$post_in);
    }
    ?>

.....

现在，当您想显示 id 为 1,2 和 3 的帖子时，只需按以下方式进行操作

 echo do_shortcode('[blog item_number=4&post_in=array(1,2,3)]');

请尝试下面的代码 - 这是简单的示例

function show_posts_by_id( $atts, $content = null, $code ) {
    $item_number = 4;
    $post_ids    = null;
    extract(
        shortcode_atts(
            array(
                'post_ids'    => '',
                'item_number' => 4,
            ),
            $atts
        ),
        EXTR_IF_EXISTS
    );
    $posts = get_posts(
        array(
            'post_type'      => 'page',
            'post__in'       => explode( ',', $post_ids ),
            'posts_per_page' => (int)$item_number,
            'offset'         => 0,
            'orderby'        => 'post_date',
            'order'          => 'DESC',
        )
    );
    // do what you need
}

add_shortcode( 'show_posts_by_id', 'show_posts_by_id' );

使用这样的简码：[show_posts_by_id post_ids=12,15,2176 item_number=4]
