permalinks - How to remove the sub-category from Woocommerce product URL

admin管理员组

文章数量:1122832

In permalinks settings the 'Shop Base with Category' /shop/%product_cat%/ permalink setting puts all the hierarchical categories in the url, for example:

http:// mystore/shop/parent-category/child-category/product

I want to remove anything between parent-category and product so my urls look like:

http:// mystore/shop/parent-category/product

I am pretty sure that setting up urls like this does not cause problems, because I can manually type the shortened url into an address bar and it goes to the same place as the longer one.

Thanks.

• This is something I have just found too, but it doesn't work if the URL is already in the browser - ie, linked externally. If Google has indexed it with the Sub Category version, can a function strip out the sub-category, and 301 it to the version asked about here? – Simon_a6 Commented Nov 17, 2023 at 14:13

It's actually quite simple. Use the woocommerce_product_post_type_link_parent_category_only filter:

add_filter( 'woocommerce_product_post_type_link_parent_category_only', '__return_true' );

Tried and tested working.

PS: The code would go into the theme functions file and __return_true() is a WordPress function.

If you just want to remove the immediate parent category slug from the URL (or any number of ancestors), there's another useful filter in wc-product-functions.php, several lines before the woocommerce_product_post_type_link_parent_category_only filter:

// Remove one or more parent categories from Woo product URL
function my_product_post_type_link_product_cat( $parent_term, $terms, $post ) {
    // Choose which products to modify
    if ( has_term('some-child-category', 'product_cat', $post ) ) {
        // Term ID of desired final category slug in URL
        $parent_term = get_term(123);
    } else if ( $post->ID == 2962 ) { // Target single product
        $parent_term = get_term(321);
    }
    return $parent_term;
}
add_filter( 'wc_product_post_type_link_product_cat', 'my_product_post_type_link_product_cat', 10, 3 );

The $permalink generated by the wc_product_post_type_link() function (which contains the aforementioned two filters) is then passed to the post_type_link filter if you prefer to take the hammer approach (for example, using str_replace).

When choosing which products to modify, avoid conditionals like is_product_category, otherwise the URL won't be modified in other places (like search results). Instead make sure to use functions that reference the ubiquitous $post object.
