在Wordpress 5.1.1中,我具有名为“ food”的自定义帖子类型。它由标题和图片库块组成。
在自定义的Wordpress rest API端点中,我想从图库中获取图像URL。
在我发送数据之前,我先遍历帖子,然后将ACF添加到帖子中,以为可以使用相同的方法。
尝试了以下Wordpress功能:
get_post_gallery()
get_post_gallery_images()
据我了解,较新的块方法。
get_post_galleries()
get_post_galleries_images()
这是我的帖子循环。 ACF方法有效。
function api_get_all_posts() {
$args = array(
'post_type' => array(
'food',
),
'post_status' => 'publish',
'order' => 'DESC',
'post_per_page' => '5'
);
$the_query = new WP_Query($args);
$posts = $the_query->posts;
if ( empty( $posts ) ) {
return new WP_Error(array( 'status' => 404 ) );
} else {
foreach ($posts as $key => $post) {
$ID = $post->ID;
//Set AFC
$posts[$key]->acf = get_fields($ID);
//Set images
$posts[$key]->images = get_post_galleries_images( $ID );
}
}
return rest_ensure_response($posts);
}
这是我发送到前端的JSON:
[
{
"ID": 44,
"post_author": "0",
"post_date": "2019-04-08 22:21:48",

"post_mime_type": "",
"comment_count": "0",
"filter": "raw",
"acf": {
"post_template": "food"
},
"images": []
}
]
通过查看“ post_content”,我可以看到图像在那里,但是找不到图库。它会一直在“图像”中给我一个空数组?
有什么建议吗? 感谢您的阅读。

这些功能仅适用于经典编辑器中使用的(旧)[gallery]
短代码,因此它们不会返回带有画廊 block 的任何内容(即<!-- wp:gallery ... -->...<!-- /wp:gallery -->
):
get_post_gallery()
get_post_gallery_images()
get_post_galleries()
get_post_galleries_images()
我不知道Gallery块的等效功能;但是,您可以使用此自定义函数获得类似于get_post_galleries_images()
返回的内容:(将此添加到主题functions.php
文件中)
function get_post_block_galleries_images( $post_id ) {
$content = get_post_field( 'post_content', $post_id );
$srcs = [];
$i = -1;
foreach ( parse_blocks( $content ) as $block ) {
if ( 'core/gallery' === $block['blockName'] ) {
$i++;
$srcs[ $i ] = [];
preg_match_all( '#src=([\'"])(.+?)\1#is', $block['innerHTML'], $src, PREG_SET_ORDER );
if ( ! empty( $src ) ) {
foreach ( $src as $s ) {
$srcs[ $i ][] = $s[2];
}
}
}
}
return $srcs;
}
然后在您的代码中,只需将其替换:
$posts[$key]->images = get_post_galleries_images( $ID );
具有:
$posts[$key]->images = get_post_block_galleries_images( $ID );
我希望这个答案对您和其他人有帮助。 :)
