Fix Link in Category Page & Email A Friend Link

Need fix for the below: 1) I have re-designed my category page for my woocommerce website. There is a link on the right hand side that says "Sell My Jewellery" - I amended the code via [login to view URL] so that the link becomes dynamic. I made the link always take the category slug, for example, whatever my category is called, the category name is taken and added to the end of the URL, i.e. sell"-category-url" However I coded it in a different fashion, I coded it so that it always take the last part of the slug. Therefore this code works well on the first page on the category page but on page-2, the url becomes sell-"page-2", and page 3 url becomes "page-3". I am sure you understand the issue. I want to make the link dynamic and working so each time the link takes category URL and applies it. Please see links below for idea: [login to view URL] - The link Sell my jewellery works fine here [login to view URL] - The link sell my jewellery breaks here because of the way i wrote the code to take just the last part of the URl. 2)When clicking email your friend, the URL of the product is not echoing in the email body. URL of product is important in the body otherwise you cannot share the product to anyone. [login to view URL] I have lots more work for right developer, but let's start with these 2 points
