我有一个名为“产品”的自定义帖子类型,它有一个下拉元框选项,用于另一个名为在线商店的自定义帖子类型(例如,商店1,商店2,商店3等)。我能够成功地将元数据键和值保存到数据库中。
在single-onlineshops.php上,我有一个产品库的一部分。是否可以在单个帖子模板下创建产品循环列表?
目前这是我的功能片段:
function MSB_custom_meta_box() {
//another add_meta_box here
add_meta_box("featured-products", "Featured Products", "featured_product_metabox", "product", "normal", "high", null);
}
add_action("add_meta_boxes", "MSB_custom_meta_box");
save_featured_product_metabox ($post_id, $post, $update) {
if ( isset( $_POST['online_shop_select'] ) ) { // Input var okay.
update_post_meta( $post_id, 'online_shop_select', sanitize_text_field( wp_unslash( $_POST['online_shop_select'] ) ) ); //
Input var okay. }
}
add_action ("save_post", "save_featured_product_metabox", 10, 3);
function featured_product_metabox ($post) {
wp_nonce_field(basename(__FILE__), "featured-product-nonce"); ?>
<label for="online_shop_select">Select Seed Bank</label>
<?php
$meta = get_post_meta( $post->ID);
$online_shop_select = ( isset( $meta['online_shop_select'][0] ) && '' !== $meta['online_shop_select'][0] ) ? $meta['online_shop_select'][0] : '';
$args_pages = array(
'post_type' => 'online-shops',
'depth' => 0,
'child_of' => 0,
'selected' => $online_shop_select,
'echo' => 1,
'name' => 'online_shop_select',
'id' => 'online_shop_select',
'class' => null,
'show_option_none' => null,
'show_option_no_change' => null,
'option_none_value' => esc_html__( '– Select –', THEME_SLUG ),
);
wp_dropdown_pages($args_pages); ?>
<br>
<?php }
非常感谢任何帮助或建议。非常感谢提前。

我想通过这段代码解决它:
$meta_value = $post->ID;
$args = array (
'post_type' => 'product',
'meta_key' => 'online_shop_select',
'meta_value' => $meta_value
);
