Unique articles on blocks

Hi, is there a global custom setting to be able to remove by default duplicate posts from the page?
Examples:
– I have a homepage with many blocks (filtered on categories) and I don’t want to have blocks to display the same posts list (as a post can belong to many categories
– or a single page with sidebar showing latest posts and I don’t want the current post to be displayed. Or on related articles and so on.

Otherwise could be interesting to implment on next release for the community.

Something like (not tested):

<?php
// Define a global array to hold the IDs of all queried posts
global $excluded_post_ids;
$excluded_post_ids = array();

// Add custom attributes to the block's HTML output
function add_custom_attributes($attributes, $block)
{
    if ($block['blockName'] === 'core/latest-posts') {
        // Add a custom attribute to the block's HTML output with the desired post order
        $attributes['data-post-order'] = get_field('post_order', $block['id']);
        // Add a custom attribute to the block's HTML output with the desired number of posts
        $attributes['data-posts-per-page'] = get_field('posts_per_page', $block['id']);
    }
    return $attributes;
}
add_filter('block_render_attributes', 'add_custom_attributes', 10, 2);

// Modify the query parameters based on the custom block attributes
function modify_query($query)
{
    global $excluded_post_ids;
    if (!is_admin() && $query->is_main_query() && $query->is_home()) {
        // Get the custom block attributes from the query string
        $post_order = isset($_GET['post_order']) ? sanitize_text_field($_GET['post_order']) : 'DESC';
        $posts_per_page = isset($_GET['posts_per_page']) ? absint($_GET['posts_per_page']) : 10;

        // Capture each post's ID and add it to the global array
        $excluded_post_ids[] = get_the_ID();

        // Modify the query parameters based on the custom block attributes
        $query->set('post__not_in', array_merge(get_option('sticky_posts'), $excluded_post_ids)); // exclude sticky posts and previously queried posts
        $query->set('orderby', 'post_date'); // sort by post date
        $query->set('order', $post_order); // set the post order based on the custom block attribute
        $query->set('posts_per_page', $posts_per_page); // set the number of posts per page based on the custom block attribute
        $query->set('ignore_sticky_posts', true); // ignore sticky posts
    }
}
add_action('pre_get_posts', 'modify_query');

// Add an action hook to capture each post's ID and add it to the global array
function capture_post_id()
{
    global $excluded_post_ids;
    $excluded_post_ids[] = get_the_ID();
}
add_action('the_post', 'capture_post_id');

?>
