Change of Permalink

It’s posible.

1) Add this code to your functions.php

function pwb_brand_permalink($permalink, $post, $leavename) {
 if (strpos($permalink, '%pwb-brand%') === FALSE) return $permalink;

 $product_brands = wp_get_object_terms($post->ID, 'pwb-brand');

 $slug = 'brand'; //default

 if ( ! empty( $product_brands ) ) {
	 if ( ! is_wp_error( $product_brands ) ) {
		 foreach( $product_brands as $brand ) {
			 $slug = $brand->slug;
		 }
	 }
 }

 return str_replace('%pwb-brand%', $slug , $permalink);
}

include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
if(is_plugin_active('woocommerce/woocommerce.php') && is_plugin_active('perfect-woocommerce-brands/main.php')){
	add_filter('post_link', 'pwb_brand_permalink', 10, 3);
	add_filter('post_type_link', 'pwb_brand_permalink', 10, 3);
}

2) Go to ‘Settings > Permalinks’ and set the custom base (for ‘Product Permalinks’):
/products/%pwb-brand%
Don′t forget to save changes.

Many thanks, titodevera.

Won’t it be better to replace is_plugin_active(‘woocommerce/woocommerce.php’) and is_plugin_active(‘perfect-woocommerce-brands/main.php’) with class_exists( ‘WooCommerce’ ) and class_exists( ‘Perfect_Woocommerce_Brands’ ) respectively?

I’m yet to try out your solution. Will update here again soon.

All is working well, except that class_exists( ‘Perfect_Woocommerce_Brands’ ) isn’t.
Looks like I’ve to stick to your intended codes instead. My bad …

By the way, I noticed when a product doesn’t have a brand assigned, its URL will be domain-name/products/brand/product-name. How do I make into, domain-name/products/product-name, which removes ‘brand’ from the URL?

Also, so far I noticed that sub-brand (or child brand) doesn’t appear to work with your plugin.

For example, I added “Brand A” as a parent brand, and “Brand B” as its child brand, the product URL only shows its parent brand, i.e., domain-name/products/Brand-A/product-name. Ideally, it should be domain-name/products/Brand-A/Brand-B/product-name.

Many thanks, titodevera.

From my point of view is more reliable to use is_plugin_active.

PWB uses php namespaces. If you want to check if a PWB class exists you should indicate the namespace before the name of the class. Something like this:
class_exists( '\Perfect_Woocommerce_Brands\Perfect_Woocommerce_Brands' );

No wonder class_exists didn’t work in this case. Thank you for the lesson. (^_^)

Anyway, any ideas on how to make the permalink recognise both parent brand, and child brand (like I’ve mentioned above) …?

For example, I added “Brand A” as a parent brand, and “Brand B” as its child brand, the product URL only shows its parent brand, i.e., domain-name/products/Brand-A/product-name. Ideally, it should be domain-name/products/Brand-A/Brand-B/product-name.

Try this code:

function pwb_brand_permalink($permalink, $post, $leavename) {
  if (strpos($permalink, '%pwb-brand%') === FALSE) return $permalink;

  $product_brands = wp_get_object_terms($post->ID, 'pwb-brand');

  $slug = 'brand'; //default

  if ( ! empty( $product_brands ) ) {
 	 if ( ! is_wp_error( $product_brands ) ) {

		 $first_brand = key( array_slice( $product_brands, 0, 1, true ) );
		 $last_brand = key( array_slice( $product_brands, -1, 1, true ) );

		 if ( $first_brand === $last_brand ) {
			 //only one brand
			 $slug = $product_brands[$first_brand]->slug;
		 } else {
			 //more than one brand
			 $slug = '';
			 foreach ($product_brands as $key => $brand) {
				 $slug .= $brand->slug;
				 if($key != $last_brand){
					 $slug .= '/';
				 }
			 }
		 }

 	 }
  }

  return str_replace('%pwb-brand%', $slug , $permalink);
 }

 include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
 if(is_plugin_active('woocommerce/woocommerce.php') && is_plugin_active('perfect-woocommerce-brands/main.php')){
 	add_filter('post_link', 'pwb_brand_permalink', 10, 3);
 	add_filter('post_type_link', 'pwb_brand_permalink', 10, 3);
 }

By the way, I noticed when a product doesn’t have a brand assigned, its URL will be domain-name/products/brand/product-name. How do I make into, domain-name/products/product-name, which removes ‘brand’ from the URL?

It is not posible remove it, but you can customize it as you want. Change this line: $slug = 'brand'; //default in the code above

Many thanks, titodevera … You ROCK !!

It is not posible remove it, but you can customize it as you want. Change this line: $slug = ‘brand’; //default in the code above

Is it possible to find out if a Product has a Brand assigned to it? If that’s possible, that function could be inserted into an IF statement, which can either leave the $slug empty or not.

Yes. It is posible find out if a product has a brand assigned or not… But if you leave the empty $slug, the products which have no brands assigned will throw a 404 error on his single page.

Thanks for the explanation. Anyway, I’ve just uploaded your new code into functions.php, and I noticed that the permalink has the parent-brand succeeding its child-brand. e.g.,

domain-name/products/brands/child-brand/parent-brand/product-name

I guess that this FOR loop is indexing the brands in reverse.

foreach ($product_brands as $key => $brand) {
	$slug .= $brand->slug;
	if($key != $last_brand){
		$slug .= '/';
	}
}

I just noticed something odd with your suggested code above. It will capture one Parent Brand only.

$first_brand = key( array_slice( $product_brands, 0, 1, true ) );
$last_brand = key( array_slice( $product_brands, -1, 1, true ) );

This is presumed that the first index within $product_brands is a Parent Brand, while the rest are its Child Brands.

What if there were multiple Parent and Child Brands, and they weren’t in any order?

Your current plugin works fine with just Parent Brands alone. But to include Child Brands will be a big leap forward.

By the way, I’ve added another screenshot into here, which reveals the Sub (or Child) Brand’s URL.

This is exactly the link in the Single Product page that I’ve been looking for. Unfortunately, I noticed that it’s ignore “/products/” from the Product Permalink Custom Base that I’d set. Strange, isn’t it?

I went sniffing around your plugin’s source code, and found in the classes folder the file class-perfect-woocommerce-brands.php that contains the action_woocommerce_single_product_summary function. In it has the following line of code.
$brand_link = get_term_link ( $brand->term_id, 'pwb-brand' );

Can this be used to alter your suggested functions.php code above? At least, it is displaying the format that I hoped for, except that it’s ignored the /product/ from the Product Permalink Custom Base.
