I’m working on implementing WordPress coding standards on a theme which has several custom post-types, each of which have underscores in their handles.
The theme uses the custom post-type handle in the file-names, eg:
archive-my_posttype.php for the
my_posttype post-type… But WordPress coding standards require that filenames use hyphens and not underscores, ( see
WordPress.Files.FileName.NotHyphenatedLowercase for more info )
I’ve changed the file-name of the archive-template to
archive-my-posttype.php but I’m apprehensive because I remember this behavior didn’t exist previously.
register_post_type( 'my_posttype' /* truncated for brevity */ );
Would correspond to the template-files
single-my_posttype.php but not
I recall being required to use the underscores in my filenames in the past. Can anyone tell me when this was changed and if it has anything to do with the rewrite-attribute being set when the CPT is registered?
I’m happy to see that I can replace the underscores with hyphens without issue, I’m just wondering when this became not an issue & if anyone knows any other conditions of this feature that people should be aware of
