我有一个页面，通过古腾堡的区块显示特定类别的最新帖子。现在我想在帖子图片的左上角添加“新建”标签。我发现里面
wp-includes/blocks/latest-posts.php
此块的代码并在其中添加自定义挂钩
add_action( 'da_custom_labels', 'render_block_core_latest_posts' );
在那之后，我在我的
functions.phpadd_filter('da_custom_labels','da_custom_labels_sales_posts');
function da_custom_labels_sales_posts() {
echo get_post_meta( get_the_ID(), 'new_real_estate', true ); //custom field
}
我尝试了很多不同的东西，但是所有的标签都出现在一排..像这样的：
NewNewNewNewNewNew
<ul>
<li> ... </li>
<li> ... </li>
<li> ... </li>
<li> ... </li>
</ul>
因此，我想在每个
li有什么想法可以实现吗？或者任何其他工作 - 解决方案？
提前致谢
经过一些研究，我找不到任何合适的钩子或过滤器来添加我自己的自定义函数。因此，最好的方法是覆盖块本身。在
functions.phpchild themeadd_filter( 'register_block_type_args', 'core_latest_posts_block_type_args', 10, 3 );
function core_latest_posts_block_type_args( $args, $name ) {
if ( $name == 'core/latest-posts' ) {
$args['render_callback'] = 'modify_core_latest_posts'; //call custom gutenberg block
}
return $args;
}
function modify_core_latest_posts($attributes) { //copy and paste the block as is, but adding custom code too
global $post, $block_core_latest_posts_excerpt_length;
$args = array(
'posts_per_page' => $attributes['postsToShow'],
'post_status' => 'publish',
'order' => $attributes['order'],

当然，可以通过自定义插件来更好地管理和组织文件。希望有帮助
