[FIXED] How to Add Multiple Taxonomies in Custom Post Permalink in WordPress URL structure

Issue

I have created a custom post type called Business Listing with multiple taxonomies("Specialty, State, City") For example: Custom post name: Dr. Jones Dental Taxonomy (Specialty): General Dentist Taxonomy (State): California Taxonomy (City): Pasadena

So currently, the url looks like this: https://test.com/business-listing/dr-jones-dental

And this is my desired URL structure should look: https://test.com/business-listing/general-dentist/california/pasadena/dr-jones-dental

However, I need to to get a perfect URL structure that is SEO friendly. So, the final URL structure should be like this: https://test.com/general-dentist/california/pasadena/. So how can I achieve this one without using a 301 redirection?

Solution

I give you my code what I use in your case
