Adding more steps to the "Post an ad" form
Hello,
I am trying to create an additional step for the ad submission form, with no success.
I am using this tutorial :
https://docs.appthemes.com/developer...p-to-checkout/
I run tests with the given code snippets, but I still don't manage to modify the checkout steps at all (no changes).
Are this codes snippets meant to be placed in the functions.php of my classipress child theme ? Or in a plugin ?
Is there a specific action hook to use, with specific priority ?
Thank you in advance for your help.
