View products in a category with certain value of custom attribute via CMS Page in Magento

Question

I have made a book store in magento. I have made a custom attribute called 'Author' that has names of author who has written the book.
I have made categories for the book like Fiction, Fantasy, Horror.
I have made a CMS page for Every Author. Eg. For CMS page of Author ABC. I have categories listed ie (Fiction, Fantasy, Horror) inside that CMS Page.
When user clicks on the Fantasy link on that CMS page I need it to redirect it to page listing Books under Fantasy Category by Author ABC I tried giving link like "magento.com/fantasy?author=1" but when we click, it redirects to "magento.com/fantasy".
How to list Books under Fantasy Category by Author ABC ?

Answer 1

You should check how default magento sends parameters in URL. When the URL switches the protocol that is from http to https, params appended with "? = " will be lost.

Try using following format : magento.com/fantasy/author/1/

Also ensure that your attribute is filterable in layered navigation and your category is marked as anchor.

Hope this helps!!
