Is there a way to make this work with hierarchical CPT?
E.g.
example.com/parent-1/subpage
example.com/parent-2/subpage

Subpage has the same name, with a different parent, and has different contents. Just the slugs are identical.

@kellenmace is this still working? For some reason, this still allows me to create a slug on my CPT that already exists on a live Page.

Hey @Garconis - Yeah, this still works and has for several years. I would make sure you’re using both code snippets from my blog post, though: https://kellenmace.com/remove-custom-post-type-slug-from-permalinks/ If you are missing the other one, that may be why WP is allowing your custom post type and pages to have the same slugs.

Your blog post said to create a plugin, do I insert both snippets into one php file? or two?

@TailonR Both snippets can go in the same PHP file. So the plugin will end up looking something like this: https://gist.github.com/kellenmace/f8a3393385f01ee226a087ff19cc6056

@kellenmace Thank you once I did that, I change "race" on lines 16 and 49, and for consistency, on line 25, and it worked.

@TailonR Nice! Glad to hear it. 👍🏼

@kellenmace could you please help me with the version of your script to remove the slug for multiple cpt's at once? I tried your answer to this on kallenmace.com from June23, 2015 (attached) but I simply can't get it to work..

I try to remove the slug from 'example1' and 'example 2' with the following code -> only 'example2' is removed,
and I get a syntax error /unexpected $EOF as well..

Thank you so much!

Greetings, Stefan

@stevek28 It looks like you're missing the $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link ); line and the curly brace after that. I assume that didn't get copied & pasted in properly. Other than that, your code looks correct to me.

Have you tried flushing the permalinks by to Settings > Permalinks in the WordPress admin and re-saving your settings (even if you haven’t changed anything on that page)?

What happens if you list example2 first and then example1 after in both places? Does only the example1 slug get removed if you do that?

@kellenmace, Hi Kellen thx for your answer! Oops I lost that line somewhere.. Now the error is gone but the slugs (both) are not removed..
Permalinks saved a few times, caches cleared, clean install, latest WP, CPT's created with CPT UI.. For a single CPT your script still woks fine..
Any Ideas? Here is the code I have right now:

`/**

• Remove the slug from published post permalinks. Only affect our custom post type, though.
  */
  function gp_remove_cpt_slug( $post_link, $post ) {

  $custom_post_types=array ( 'example1', 'example2' );

  if ( ! in_array( $post->post_type, $custom_post_types ) ||'publish'!=$post->post_status ) {
  $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );
  }

  return $post_link;
  }
  add_filter( 'post_type_link', 'gp_remove_cpt_slug', 10, 2 );

Thank you so much for your help! Stefan

The code works for Parent Pages but for the child pages.
I am trying to remove the word 'slug' here

domain.com/slug/hosting (works)
domain.com/slug/hosting/wp-engine (getting 404 error)

My CPT is hierachical where the second links is the child of the first link. I am getting 404 error for the second.
