如何在wordpress中设置自定义页面URL

Actually, I am using advance custom field plugin and I have made a repeater with three fields language, release and download (file type).

So now I have made a custom template for every post and retrieved repeater fields on it so I want that when user will click on download button then it will redirect on another page with a custom URL with post name and language both.

I need post name and language into that link then on final page

I will give the download option. Below are pages link of the post

I have also set download page on custom page.

Let me know the right solution for it.

If i were you i would follow these steps.

1. Create a new page with name of Custom download maybe
2. create a custom template for that page
3. in your posts when you show repeater values, use the values like a form with GET method (maybe input types can be hidden for aesthetic) and submit the form to this new page.
4. In this page you can get the repeater field values with form and do whatever you want.

NOTE: i suggested GET method because you said "... it will redirect on other page with a custom url .." GET method show values in url and you can index them.
