Currently, the only way to add new input fields to the “Add a listing” page is via wordpress hooks (php code)
Our plugins are perfect examples of this. They add fields to the “Add a Listing” page, as well as other features like the search filter.
These hooks are not well documented. However, you can easily see them in the template files. You can use them like any other wordpress hook
In general, every layout aspect of BePro Listings has hooks including, listings, filter search, add a listings page, and the item page. There are also tons of hooks spread throughout the system to interface with various events like form saving.
