Wordpress 转储：特色图片不起作用（仅限前端）

Question

我正在尝试让特色图片（缩略图）显示在前端。后端就像一个魅力。但是，我在获取此自定义 post 类型和默认 post 类型的缩略图时遇到问题。它适用于 single.twig 文件，但不适用于 home.twig（相当于首页）。当我 dump() 变量时，我得到了我需要显示的所有内容，除了特色图片。

问题可能出在哪里？

WordPress：5.2.2
木材：1.9.2
ACF 专业版：5.8.3
没有其他插件

home.twig（简体）

{% for event in events %}
  {{ event.thumbnail.src }} //does not work
  {{ event.title }} //works
{% endfor %}

index.php

$context['events'] = get_posts(array(
    'numberposts'   => -1,
    'post_type'     => 'Events',
    'orderby' => 'DATE',
    'order' => 'DESC'
));

functions.php

add_action( 'init', 'create_posttype' );
/*
* Creating a function to create our CPT
*/

//START CUSTOM POST TYPE
function custom_post_type() {

// Set UI labels for Custom Post Type
    $labels = array(
        'name'                => _x( 'Events', 'Post Type General Name', 'the-template' ),
        'singular_name'       => _x( 'Event', 'Post Type Singular Name', 'the-template' ),
        'menu_name'           => __( 'Events', 'the-template' ),
        'parent_item_colon'   => __( 'Parent Event', 'the-template' ),
        'all_items'           => __( 'All Events', 'the-template' ),
        'view_item'           => __( 'View Event', 'the-template' ),
        'add_new_item'        => __( 'Add New Event', 'the-template' ),
        'add_new'             => __( 'Add New', 'the-template' ),
        'edit_item'           => __( 'Edit Event', 'the-template' ),

        'not_found_in_trash'  => __( 'Not found in Trash', 'the-template' ),
    );

// Set other options for Custom Post Type

    $args = array(
        'label'               => __( 'events', 'the-template' ),
        'description'         => __( 'Event news', 'the-template' ),
        'labels'              => $labels,
        // Features this CPT supports in Post Editor
        'supports'            => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'revisions', 'custom-fields', ),
        // You can associate this CPT with a taxonomy or custom taxonomy.
        'taxonomies'          => array( 'genres' ),
        /* A hierarchical CPT is like Pages and can have
        * Parent and child items. A non-hierarchical CPT
        * is like Posts.
        */
        'hierarchical'        => false,
        'public'              => true,
        'show_ui'             => true,

        'publicly_queryable'  => true,
        'capability_type'     => 'page',
    );

    // Registering your Custom Post Type
    register_post_type( 'Events', $args );

}

/* Hook into the 'init' action so that the function
* Containing our post type registration is not
* unnecessarily executed.
*/

add_action( 'init', 'custom_post_type', 0 );

Answer 1

试试这个

{% for event in events %}
{% set image = TimberImage(event.thumbnail) %}
    {{ image.src }}
    {{ event.title }}
{% endfor %}

Answer 2

当您使用 get_posts() 时，您会收到普通的 WordPress 帖子，您需要 Timber 帖子。使用 Timber::get_posts() 而不是 get_posts() 来取回 Timber\Post 而不是 WP_Post.

的实例

index.php

$context['events'] = Timber::get_posts( array(
    'numberposts' => -1,
    'post_type'   => 'Events',
    'orderby'     => 'DATE',
    'order'       => 'DESC'
) );
