I have managed to add a custom post type in a plugin using online tutorials. I don't know what to do next. I have copied the single.php and archive.php from my theme as single-listing.php and archive-listing.php but that does nothing.
I have put this
<?php query_posts( 'post_type=listing' ); ?> in my page following some of the instructions in tutorials I have read but still limited success.
I have read loads of stuff on CPT but I am not a coder. Most of the material online gives heaps of information on how to build a CPT but little advice about what to do after.
What I am trying to achieve is a directory site using a CPT.
What should I do next?
