1 post, 2 templates

Question

I want to be able to render post in two different styles (2 templates).

For example, let's say I have the post ID 133, I would like two URLS to access it and so it renders where different template would apply.

• lorem.com/render1/133
• lorem.com/render2/1333

for example... or it could be something like:

• lorem.com/post/133
• and lorem.com/post/133?template=2

How would you do it?

Answer 1

Your best bet would probably be the Rewrite Endpoints API. The API allows you to create post URLs with endpoints like lorem.com/post/133/json/ or lorem.com/post/133/print/. You'll find useful code examples in the link provided.

Answer 2

If you add a query arg, via add_query_arg(), you could then query that query arg, via get_query_var(), inside of a callback hooked into template_redirect.

(Note: how/why you add the query arg is outside the scope of this answer.)

For example:

function wpse82168_template_redirect() {
    // You'll need to update these conditionals according to your context
    if ( is_single() && get_query_var( 'template' ) && '2' == get_query_var( 'template' ) ) {
        get_template_part( 'template-2' );
    }
}
add_action( 'template_redirect', 'wpse82168_template_redirect' );
