WordPress REST API v2 返回所有图像,而不仅仅是来自选定的 Post
WordPress REST API v2 returning all images, not just from selected Post
我正在尝试通过编辑 functions.php 文件向 REST API 添加一些字段。由于我对 WP 没有太多经验,我研究了如何做并想出了以下代码:
add_action( 'rest_api_init', 'add_images_to_JSON' );
function add_images_to_JSON() {
register_rest_field(
'post',
'images',
array(
'get_callback' => 'get_images_src',
'update_callback' => null,
'schema' => null,
)
);
}
function get_images_src( $object, $field_name, $request ) {
$args = array(
'posts_per_page' => -1,
'order' => 'ASC',
'orderby' => 'menu_order',
'post_mime_type' => 'image',
'post_parent' => $object->id,
'post_status' => null,
'post_type' => 'attachment',
'exclude' => get_post_thumbnail_id()
);
$attachments = get_children( $args );
$images = [];
foreach ($attachments as $attc){
$images[] = wp_get_attachment_thumb_url( $attc->ID );
}
return $images;
}
问题是,当我按类别获得 post 的列表时,这将返回所有 post 中的所有图像,而不仅仅是与其相关的图像。我怎样才能让每个 post returns 只有它的相关图像?
试试这个:
function get_images_src( $object, $field_name, $request ) {
$images = [];
$post_images = get_attached_media('image', $object->ID);
foreach($post_images as $image) {
$images[] = wp_get_attachment_image_src($image->ID,'full');
}
return $images;
}
