Custom Post types not working

Hi @goldfinch44.

First off, you never want to directly edit a plugin, theme, or core WordPress file. Any changes you make will be lost when you update the plugin/theme/WordPress.

This is what filters and actions are for. You can safely add support for additional post types in this plugin using the fpw_post_types filter (referenced in the FAQ). You can see examples of how to use that in this gist.

The code you write should go in your theme’s functions.php file or a custom plugin for your site.

OK yes I’m totally not a php guy, sorry – so I added the code (for adding a post type, not removing one) on your gist page to my theme’s functions.php file, changed your example “book” to mine, “books”, and it’s still not working. Is there a plugin you recommend I can add the php to and maybe that’ll work?

It sounds like that should be working, so I’m not quite sure what to tell you. I’d double-check that “book” is the actual slug of your custom post type. For example if you go to the “All Books” page of your admin, it’ll be at a URL like this:

https://example.com/wp-admin/edit.php?post_type=xyz_books

In that case, “xyz_books” is the value the filter will need. I wouldn’t recommend a PHP execution plugin. If you want to try something else, try an mu-plugin.

okay, got it to work, thanks for bearing with me. NOW… I want to have TWO custom post types added, but if I paste that snippet twice I get an error. Do I just append another post type to that filter? If so, where exactly?

For posterity, can you post your solution to help other people?

You can’t declare the same function name twice. Instead, you just need to add a second post type to the $post_types array:

<?php
add_filter( 'fpw_post_types', 'fpw_add_post_type_to_feature' );
function fpw_add_post_type_to_feature( $post_types ) {
	$post_types[] = 'book';
	$post_types[] = 'another_post_type'; /* ADD THIS LINE */
	return $post_types;
}
?>

I redid everything you told me to do above, and this time it worked. I don’t know if it was a cache thing keeping it from working, or what. For example, after I just added “authors,” it took quite a while for it to work, after several cache purges. (Can you tell I’m not super technical?)

THANKS!!

Glad I could help ??
