Hello

I made myself roughly 50 fake posts of content for testing purposes (with tags, categories, lorem-ipsum-generated text, different shortcodes used, etc.) but I was sloppy enough to have them in very specific order (all from one category, then all from the other etc.).

To be able to test how different-styled posts look next to each other I needed a way to order them randomly. I found this piece of code:

session_start();
add_filter( 'posts_orderby', 'randomise_with_pagination' );
function randomise_with_pagination( $orderby ) {
	if( is_front_page() ) {
	  	// Reset seed on load of initial archive page
		if( ! get_query_var( 'paged' ) || get_query_var( 'paged' ) == 0 || get_query_var( 'paged' ) == 1 ) {
			if( isset( $_SESSION['seed'] ) ) {
				unset( $_SESSION['seed'] );
			}
		}
	
		// Get seed from session variable if it exists
		$seed = false;
		if( isset( $_SESSION['seed'] ) ) {
			$seed = $_SESSION['seed'];
		}
	
	    	// Set new seed if none exists
	    	if ( ! $seed ) {
	      		$seed = rand();
	      		$_SESSION['seed'] = $seed;
	    	}
	
	    	// Update ORDER BY clause to use seed
	    	$orderby = 'RAND(' . $seed . ')';
	}
	return $orderby;
}

Which does exactly what I need but only on the blog page (AKA all posts page). Can You guys help me modify this code to make posts ordered randomly on category-archive pages too (by that I mean inside X category archive there are still only posts from X category but ordered randomly, and inside Y category archive there are still only posts from Y category but ordered randomly, etc.)?

Thanks in advance and good day to You all 🙂

Hi There,

Thanks for posting in.
From your code, please update this line:
if( is_front_page() ) { => This code refers to blog index page
To this:
if( is_front_page() || is_category()) { => This code means blog index page or category page
In case you want to be specific, please update to this:
if( is_front_page() || is_category(1) || is_category(2)) { =>This code means blog index page or specific category page
Replace 1 and 2 with your own category ID.

Works like a charm, without any visible issues as far as I can tell 🙂

Thank You Lely 🙂
