GenerateWP allows you to generate code for your WordPress theme using simple forms. I’m not sure how much help it would be to someone unfamiliar with theme development or PHP (simply because troubleshooting the code itself could still be necessary), but I’ve found it very handy in creating snippets for
functions.php files without having to dig around in the WordPress Codex for code examples.
Some of the code you can create includes functions for custom taxonomies, custom posttypes, post statuses and even snippets for your
wp-config.php file. As you’re filling out forms to generate the code, it’s also a great way to make sure all the function variables are accounted for — for me, that means not forgetting important elements that help users, like updating all of the page labels for custom post types.
