Order by stock status (posts_clauses) drop ACF get_field function

Hello @andygroove,

I found an easier approach here: https://stackoverflow.com/a/62353255

It adds an “availability” option on the shop page for ordering products based on stock.

If you want to change the “Availability” string, you can edit the following part ( 'Availability', in $orderby['availability'] = __( 'Availability', 'woocommerce' );.

Hope this helps!

Funny you should post this, I just finished debugged this issue on a client site.

add_filter('posts_clauses', 'sem_order_by_stock_status');
function sem_order_by_stock_status($posts_clauses) {
    global $wpdb;
    // only change query on WooCommerce loops when ACF fields are not requested in the WHERE statement
    if (!is_acf_request($posts_clauses['where']) && is_woocommerce() && (is_shop() || is_product_category() || is_product_tag() || is_product_taxonomy())) {
        $posts_clauses['join'] .= " INNER JOIN $wpdb->postmeta istockstatus ON ($wpdb->posts.ID = istockstatus.post_id) ";
        $posts_clauses['orderby'] = " istockstatus.meta_value ASC, " . $posts_clauses['orderby'];
        $posts_clauses['where'] = " AND istockstatus.meta_key = '_stock_status' AND istockstatus.meta_value <> '' " . $posts_clauses['where'];
    }
    return $posts_clauses;
}

function is_acf_request($text){
	if (strpos($text, 'acf-field'))
		return true;
	return false;
}

I can think of some edge cases where this would need to be further optimized but this should work for 99.999% of sites out there.

jake4u thank you so much. Its work for me

Awesome, @andygroove glad to know it’s working for you. I’m going to mark this as resolved – if you have any further questions, you can start a new thread.

Cheers!
