Get page permalink without wpurl

Question

I currently have an ID of a page that I want to use its permalink as the front of a permastruct of a CPT I'm setting up.

Now I can use get_permalink() but that returns the full URL:

http://www.example.com/imapage/subpage/subsubpage

but all I want to return is imapage/subpage/subsubpage

Is there a function that can do this or do I have to device something that can subtract the non-needed part of the url?

Answer 1

There's nothing built in to return the bit you want but it should be as easy as using the home_url() function and removing it's output from the full url eg:

function get_relative_permalink( $url ) {
    return str_replace( home_url(), "", $url );
}

Answer 2

There's actually a core function for this now. wp_make_link_relative($url)

Convert full URL paths to relative paths.

Removes the http or https protocols and the domain. Keeps the path '/' at the beginning, so it isn't a true relative link, but from the web root base.

Example

<?php echo wp_make_link_relative('http://localhost/wp_test/sample-page/'); ?>

This will output /wp_test/sample-page/

Example with Post ID <?php echo wp_make_link_relative(get_permalink( $post->ID )); ?>

Example for current post <?php echo wp_make_link_relative(get_permalink()); ?>

More about this can be found in the documentation.

Answer 3

You won't be able to use get_permalink() for that.

If you dig into the code for that function in /wp-includes/link-template.php you'll see why. After the permalink structure is parsed and prepared, the code does this:

$permalink = home_url( str_replace($rewritecode, $rewritereplace, $permalink) );

This is performed immediately after the structure of the link is created and before anything is passed through a useful filter.

So unfortunately, you'll have to extract the non-needed part of the URL yourself. I'd recommend using the str_replace() function that @sanchothefat suggested.

Answer 4

$path = parse_url(get_permalink(...), PHP_URL_PATH); ... gives the URL PATH only. This is not relative to blog root but to domain. It's the absolute URI.

Answer 5

$relative_permalink = wp_make_link_relative(get_permalink($post->ID));

wp_make_link_relative( string $link )

Removes the http or https protocols and the domain. Keeps the path ‘/’ at the beginning, so it isn’t a true relative link, but from the web root base.
