The bulk_edit_posts() WordPress PHP function updates all bulk edited posts or pages, adding (but not removing) tags and categories. It specifically avoids processing pages when they would be their own parent or child.
Usage
Here’s a basic example of how you can use bulk_edit_posts(). Assume you have an array of post data, $post_data, that you want to process:
$post_data = array(
'post_type' => 'post',
'tags_input' => array('tag1', 'tag2'),
'post_category' => array(1, 2)
);
bulk_edit_posts($post_data);
In this example, bulk_edit_posts($post_data) will process all the posts, adding ‘tag1’ and ‘tag2’ as tags, and adding them to categories 1 and 2.
Parameters
$post_data(array|null) (Optional): The array of post data to process. Defaults to the$_POSTsuperglobal. Default: null
