How to modify the custom post type slugs for each listing type for localisation or other names

Each of the 7 post types have filters that allow you to change the slug name to whatever you like, this is especially important for localisation.

So to change the /property slug to /casa for Italy for example you have a few filters inside each post type.

// Property Post Type
$archives = defined( 'EPL_PROPERTY_DISABLE_ARCHIVE' ) && EPL_PROPERTY_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_PROPERTY_SLUG' ) ? EPL_PROPERTY_SLUG : 'property';
$rewrite  = defined( 'EPL_PROPERTY_DISABLE_REWRITE' ) && EPL_PROPERTY_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Rental Post Type
$archives = defined( 'EPL_RENTAL_DISABLE_ARCHIVE' ) && EPL_RENTAL_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_RENTAL_SLUG' ) ? EPL_RENTAL_SLUG : 'rental';
$rewrite  = defined( 'EPL_RENTAL_DISABLE_REWRITE' ) && EPL_RENTAL_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Land Post Type
$archives = defined( 'EPL_LAND_DISABLE_ARCHIVE' ) && EPL_LAND_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_LAND_SLUG' ) ? EPL_LAND_SLUG : 'land';
$rewrite  = defined( 'EPL_LAND_DISABLE_REWRITE' ) && EPL_LAND_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Rural Post Type
$archives = defined( 'EPL_RURAL_DISABLE_ARCHIVE' ) && EPL_RURAL_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_RURAL_SLUG' ) ? EPL_RURAL_SLUG : 'rural';
$rewrite  = defined( 'EPL_RURAL_DISABLE_REWRITE' ) && EPL_RURAL_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Business Post Type
$archives = defined( 'EPL_BUSINESS_DISABLE_ARCHIVE' ) && EPL_BUSINESS_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_BUSINESS_SLUG' ) ? EPL_BUSINESS_SLUG : 'business';
$rewrite  = defined( 'EPL_BUSINESS_DISABLE_REWRITE' ) && EPL_BUSINESS_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Commercial Post Type
$archives = defined( 'EPL_COMMERCIAL_DISABLE_ARCHIVE' ) && EPL_COMMERCIAL_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_COMMERCIAL_SLUG' ) ? EPL_COMMERCIAL_SLUG : 'commercial';
$rewrite  = defined( 'EPL_COMMERCIAL_DISABLE_REWRITE' ) && EPL_COMMERCIAL_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

// Commercial Land Post Type
$archives = defined( 'EPL_COMMERCIAL_LAND_DISABLE_ARCHIVE' ) && EPL_COMMERCIAL_LAND_DISABLE_ARCHIVE ? false : true;
$slug     = defined( 'EPL_COMMERCIAL_LAND_SLUG' ) ? EPL_COMMERCIAL_LAND_SLUG : 'commercial-land';
$rewrite  = defined( 'EPL_COMMERCIAL_LAND_DISABLE_REWRITE' ) && EPL_COMMERCIAL_LAND_DISABLE_REWRITE ? false : array('slug' => $slug, 'with_front' => false);

You can rename the slug like so:

<?php define( 'EPL_PROPERTY_SLUG' , 'casa' );?>

You can also set a different slug for the archive (search results) using:

<?php 
function my_epl_property_post_type_args( $array ) {
	$array['has_archive'] = 'properties';
	return $array;
}
add_filter( 'epl_property_post_type_args', 'my_epl_property_post_type_args' );

?>

After adding this function you must reset your WordPress permalinks from Dashboard > Settings > Permalinks > Save Changes
