Getting the Site URL Including the Front Base

Question

If my permalink structure is set to /blog/%postname%/, how can I retrieve a URL for my site which retrieves domain.com/blog/?

With the permalink structure mentioned above, when using site_url();, it displays domain.com/ when I'm looking to easily get the site's URL including the front base.

Maybe I'm unclear about what the "front base" actually is.

I'm under the impression that the front base is your "Permalink Structure". (Stored in the option permalink_structure)

I've tried home_url(); and site_url(); ... Both output just domain.com/

I'm thinking about just using site_url(); then retrieving the option permalink_structure, parsing the contents of the option myself, then appending it to the site_url(); function.

$permalink_structure = get_option('permalink_structure');
$front_base = preg_replace('#(\%)(.*)(\%/)#si', '', $permalink_structure);
echo site_url($front_base, 'http').PHP_EOL;

Is there an easier way to get the site's URL including the front base?

Answer 1

You can get the value of front in the global $wp_rewrite:

global $wp_rewrite;
echo $wp_rewrite->front;
// or
echo home_url( $wp_rewrite->front );

Though that is probably of limited use, as the front base isn't necessarily an existing page, and may 404 in many cases. If you're using that value to prepend to other URLs, you're likely doing it wrong.

If you want the page designated as the posts page, that value is stored in the page_for_posts option:

echo get_permalink( get_option( 'page_for_posts' ) );

Answer 2

I was about to suggest something like the function bellow, but lets face it @Milo's answer is just a bit smarter, so just for completeness reason and because I already wrote it down.

function wpse163163_site_url_with_fix_permalink_base() {
    return 
        get_site_url()
        . '/'
        . preg_replace(
            '/\%([a-z0-9]+?)\%/i',
            '',
            str_replace(
                '/',
                '',
                get_option('permalink_structure')
            )
        )
        . '/';
}

You will have to get link like this.

<?php echo home_url( '/blog' ); ?>

or

<?php echo home_url( '/' ) . 'blog'; ?>
