php - 在 CMB2 选项中添加帖子类别

Question

我需要在我的 CMB2 WordPress 插件的下拉选项中添加特定类型的帖子。我已经找到在我的代码中生成我的字段的位置；然而，我看到 taxonomies 被用作过滤器，但我需要一个帖子 post_type。

使用分类法

$cmb_events->add_field( array (
    'name'      => __('Catégorie d\'événement','aqmat'),
    'id'        => $prefix . 'categorie',
    'type'      => 'taxonomy_select',
    'taxonomy'  => 'aqmat_categorie_evenement'
));

我想我会查询我的帖子以仅获取我想要的帖子，并使用逻辑作为 taxonomy 字段将它们添加到下拉列表中

我尝试获取我的帖子类型

// Get posts in desired category
$posts = array();
$args = array(
            'post_type'      => 'post_type_i_want',
            'orderby'        => 'id',
            'posts_per_page' => -1
        );
$getPosts = get_posts($args);
foreach($getPosts as $post) {
    setup_postdata($post);
    // Yes, I am aware I would *technically* have several times the same value
    // Not getting there yet, so not an issue for me right now
    // Besides, my category currently has but 1 post
    array_push($getPosts, array(
        'standard' => __( 'Option value', 'cmb2' )
    ));
}
// Add field
$cmb_events->add_field( array (
    'name'      => __('Label','cmb2'),
    'id'        => $prefix . 'enseignant',
    'type'      => 'taxonomy_select',
    'options'   => $teamMembers
));

但是，我没有收到任何错误，下拉列表中也没有任何值。在官方Documentation中查询帖子似乎得不到多少，所以我对这个问题一无所知。有什么建议吗？

您似乎正在将 $teamMembers 分配给选项，但它未定义且未分配任何值。

// Get posts in desired category
$posts = array();
$args = array(
        'post_type'      => 'post_type_i_want',
        'orderby'        => 'id',
        'posts_per_page' => -1
    );
$getPosts = get_posts($args);
foreach($getPosts as $post) {
    setup_postdata($post);
    // Yes, I am aware I would *technically* have several times the same value
    // Not getting there yet, so not an issue for me right now
    // Besides, my category currently has but 1 post
    array_push($posts, array(
    'standard' => __( 'Option value', 'cmb2' )
));
}
// Add field
$cmb_events->add_field( array (
    'name'      => __('Label','cmb2'),
    'id'        => $prefix . 'enseignant',
    'type'      => 'taxonomy_select',
    'options'   => $posts
));

试试这段代码，希望你能得到选项值
