Setting permalink structure to /post/%post_id%/ shows post in author slug

This is default WordPress behavior, but it can be changed. It just depends on whether or not you’re willing to mess with code. Let me know. I’ve also added this as a feature request on GitHub.

Hi, yes, I’m willing to write / edit some code. If you have something in mind or a hint of what to edit it would be a great help. Is it something that can be done with filters?
Many thanks

The below code is best place in a functionality plugin (basically a plugin that just has random functions). However, it will also work in your theme’s functions.php file. Keep an eye on the release notes of future versions of Edit Author Slug, as this will be added as a feature. It shouldn’t cause any problems, but it will be duplicating functionality.

Once you’ve placed the code, and activated your functionality plugin, should you choose that route, you’ll need to go to Settings > Permalinks, and click “Save.” No changes are necessary, but you’ll need this step to make your new author links, sans “post/”, resolve.

function my_remove_front_from_author_structure() {
	global $wp_rewrite;

	if ( empty( $wp_rewrite->permalink_structure ) ) {
		$this->author_structure = '';
		return false;
	}

	$wp_rewrite->author_structure = '/' . $wp_rewrite->author_base . '/%author%';

	return $wp_rewrite->author_structure;
}
add_action( 'init', 'my_remove_front_from_author_structure', 2 );

I just released version 1.2.0 which has this functionality baked in. If you were using the code I posted above, you’ll want to remove it, or at least comment out the add_action( 'init', 'my_remove_front_from_author_structure', 2 );, before using the built-in version.
