query for single-posttype.php – if statement needed

Currently I have the following query to return posts of the post_type “accommodation” in taxonomy “apartmentcat” that value is the same apartmentcat value as the page of posts they are on.

so the following works a treat..

<?php
global $post;
$terms = get_the_terms($post->ID, 'apartmentcat');
$slugs = array();
foreach ( $terms as $term )
$slugs[] = $term->slug;
$other_posts = new WP_Query('post_type=accommodation&apartmentcat='.$slugs[0].'&showposts=30&orderby=menu_order');
if ($other_posts->have_posts()):
while ($other_posts->have_posts()): $other_posts->the_post();

{ do stuff }

endwhile;
endif;
wp_reset_query(); ?>

Buy now, I need to change it to an if statement so I can use one single-posttype.php template for 2 different results.

This is what I need it to do.

query post type = “accommodation”

if property_type(taxonomy) = apartment(value)
query taxonomy “apartmentcat” (same outcome as above, so if im on the Chevron Apartment page, other Chevron apartments will also show)

{ do stuff }

else
if property_type(taxonomy) = holiday-home(value)
query taxonomy “suburbs” (so if I’m on a Surfers holiday home page, then other Surfers holiday will also show)

{ do stuff }

Is anyone able to assist me with this?
