使用MySQL SELECT查询获取父级的子级

Posted 2021-02-22

Plugin gets child pages of parent in Wordpress. You'll need to pass the parent ID but this isn't difficult to figure out programmatically if needed, either.

<?php
 
// Include Wordpress framework/API
require_once( '/path/to/wp-load.php' );
 
 
// Get parents (level one)
$items_level_one = $wpdb->get_results(
	'SELECT
		*
	FROM
		wp_posts
	WHERE
		post_type = "Page" AND
		post_status = "Publish" AND
		post_parent = "[put parent id here]"
	ORDER BY
		menu_order,
		post_title',
	ARRAY_A
);
 
print_r($items_level_one);
 
?>
