WP以CPT标题为属性的短代码

我创建了一个具有3个自定义字段的CPT(自定义字段在ACF插件中完成)。我有一个在我的主题中显示自定义帖子的简码。到目前为止, 一切都很好。

我的问题是当我有多个CPT时, 我想要一个shortcode属性, 让用户指定他们要显示的自定义帖子。

当前, 根据我设置的posts_per_page来决定显示哪个帖子。它完全忽略了属性。

这是我所拥有的：

// create custom post for jumbotron
function jumbotron_post_type()
{
    $labels = array(
        'name' => 'Jumbotrons', 'singular_name' => 'jumbotron');
    $supports = array(
        'title'        
    );
    $args=array(
    'labels' => $labels, 'supports' => $supports, 'public' => true
    );
    register_post_type('Jumbotrons', $args);
}
add_action('init', 'jumbotron_post_type');

// create shortcode for display

function show_jumbotron($atts, $content = null )
{
   extract(shortcode_atts(array(
      'id' => 'new-jumbo', 'per_page' => -1, ), $atts));

    $args = array(
        'posts_per_page' => $per_page, 'title' => $id, 'post_type' =>'Jumbotrons'        
    );
    $results = new WP_Query($args);

    while ($results->have_posts()):
        $results->the_post();
    ob_start(); ?>
            <section class="jumbotron">
                <div class="jumbotron--container">
                    <h1><?php the_field('jumbotron_title'); ?></h1>
                    <p class="info"><?php the_field('jumbotron_body'); ?></p>
                    <h2 class="u--text__right"><?php the_field('jumbotron_end_heading'); ?></h2>
                </div>
            </section>
            <?php
        $content = ob_get_clean();
    endwhile;
    wp_reset_postdata();
    return $content;
};

add_shortcode('jumbotron', 'show_jumbotron');

在主题中, 我有：

<?php echo do_shortcode('[jumbotron id="Homepage Jumbotron"]');?>   

如果我将posts_per_page设置为-1, 它将显示最早的自定义帖子。如果我设置为1, 那么它将显示最新的。

2个CPT标题是：

• 新巨无霸
• 巨无霸首页

我的意图是使[jumbotron title =” Homepage Jumbotron”]根据输入的标题显示正确的自定义帖子, 默认标题为” New Jumbo”。

我发现了错误。 ID需要设置为空字符串

'id' => ''

工作代码是：

// create shortcode for display

function show_jumbotron($atts, $content = null )
{
    extract(shortcode_atts(array(
      'id' => '', 'per_page' => -1, ), $atts));

    $args = array(
        'post_type' =>'Jumbotrons', 'posts_per_page' => $per_page, 'title' => $id
    );
    $results = new WP_Query($args);

    while ($results->have_posts()):
        $results->the_post();
    ob_start(); ?>
            <section class="jumbotron">
                <div class="jumbotron--container">
                    <h1><?php the_field('jumbotron_title'); ?></h1>
                    <p class="info"><?php the_field('jumbotron_body'); ?></p>
                    <h2 class="u--text__right"><?php the_field('jumbotron_end_heading'); ?></h2>
                </div>
            </section>
            <?php
        $content = ob_get_clean();
    endwhile;
    wp_reset_postdata();
    return $content;
};

add_shortcode('jumbotron', 'show_jumbotron');

Hey megler use my below code. I hope it should work.

function show_jumbotron($atts, $content = null )
{
   extract(shortcode_atts(array(
      'title' => 'New Jumbo', 'per_page' => 1, ), $atts));

    $args = array(
        'posts_per_page' => $per_page, 'title' => $title, 'post_type' =>'Jumbotrons'        
    );
    $results = new WP_Query($args);

    while ($results->have_posts()):
        $results->the_post();
    ob_start(); ?>
            <section class="jumbotron">
                <div class="jumbotron--container">
                    <h1><?php the_field('jumbotron_title'); ?></h1>
                    <p class="info"><?php the_field('jumbotron_body'); ?></p>
                    <h2 class="u--text__right"><?php the_field('jumbotron_end_heading'); ?></h2>
                </div>
            </section>
            <?php
        $content = ob_get_clean();
    endwhile;
    wp_reset_postdata();
    return $content;
};

add_shortcode('jumbotron', 'show_jumbotron');

Then add shortcode like this:

<?php echo do_shortcode('[jumbotron title="Homepage Jumbotron"]');?>   
<?php echo do_shortcode('[jumbotron title="New Jumbo"]');?>   

I hope this will work. 

Thank you.
