Remove Cetain Post Categories From Blog Sidebar Archive List

Can you share a link to your site? What theme are you using?

It is ithemes builder with classen child theme. I have posted on their forum but I am not having much luck.

Warning – The site belongs to a professional author who writes erotic fiction of the Fifty Shades of Grey genre! https://www.tessavalmur.com/blog/

Try excluding the categories with this in your theme’s functions.php:

define("EXCLUDED_CATEGORIES", '25,55,57');

add_filter( 'getarchives_join' , 'getarchives_join_filter');
function getarchives_join_filter( $join ) {
	global $wpdb;
	return $join . " INNER JOIN {$wpdb->term_relationships} tr ON ($wpdb->posts.ID = tr.object_id) INNER JOIN {$wpdb->term_taxonomy} tt ON (tr.term_taxonomy_id = tt.term_taxonomy_id)";
}

add_filter( 'getarchives_where' , 'getarchives_where_filter');
function getarchives_where_filter( $where ) {
	global $wpdb;

	$exclude = EXCLUDED_CATEGORIES; // category ids to exclude
	return $where . " AND tt.taxonomy = 'category' AND tt.term_id NOT IN ($exclude)";

	}

// exclude categories on monthly archive pages
function my_post_queries( $query ) {
	// do not alter the query on wp-admin pages and only alter it if it's the main query
	if (!is_admin() && $query->is_main_query()){

		// alter the query for monthly archive pages
		if(is_archive() && is_month()){
			$query->set('category__not_in', array(EXCLUDED_CATEGORIES));
		}
	}
}

add_action( 'pre_get_posts', 'my_post_queries' );

Change the category IDs you want to exclude in define("EXCLUDED_CATEGORIES", '25,55,57'); to the correct category ID’s

Thank you – that works well. The unwanted post categories have gone from the chronological archive list. But it has thrown up another problem which I’m not sure if is related.

When you click on the October archives, a list of posts is displayed (there are currently two – post 1 and post 2) but only the body text of the post displays – no headings or details.

Did headings or details show up before you used my code?

Can you paste and submit the full code of archive.php of your theme into a pastebin.com and post the link to it here? see the Forum Rules for posting code and using the pastebin.

I have just tried removing your code from the function.php and the same problem was still there for the ‘blog’ category posts (posts 1 and 2) but the ‘novels’ category posts were formatted as per the actual Novels page. (I have now replaced your code).

Here is the code for the archive.php

Thanks for you help.

This in your stylesheet style.css is hiding the titles:

/*********************************************
    post/page titles
*********************************************/
.entry-title {
 display: none;
}

Remove it and the titles will show up.

Many thanks for you help.

i also tried

define("EXCLUDED_CATEGORIES", '25,55,57');

add_filter( 'getarchives_join' , 'getarchives_join_filter');
function getarchives_join_filter( $join ) {
	global $wpdb;
	return $join . " INNER JOIN {$wpdb->term_relationships} tr ON ($wpdb->posts.ID = tr.object_id) INNER JOIN {$wpdb->term_taxonomy} tt ON (tr.term_taxonomy_id = tt.term_taxonomy_id)";
}

add_filter( 'getarchives_where' , 'getarchives_where_filter');
function getarchives_where_filter( $where ) {
	global $wpdb;

	$exclude = EXCLUDED_CATEGORIES; // category ids to exclude
	return $where . " AND tt.taxonomy = 'category' AND tt.term_id NOT IN ($exclude)";

	}

// exclude categories on monthly archive pages
function my_post_queries( $query ) {
	// do not alter the query on wp-admin pages and only alter it if it's the main query
	if (!is_admin() && $query->is_main_query()){

		// alter the query for monthly archive pages
		if(is_archive() && is_month()){
			$query->set('category__not_in', array(EXCLUDED_CATEGORIES));
		}
	}
}

add_action( 'pre_get_posts', 'my_post_queries' );

but this exclude only the first cat_id, for example if i have ‘1,3,8’ it will exclude only cat_id=1. How i can fix this?
