Creating a Custom Function

ello,

On my website, we have a list of aircraft that our company has for sale. Much like an online shop, we have a page with a picture of each aircraft and a link to the product details for each. I would like to create a function so that my company can add aircraft as needed through a backend form. My guess is that I would need one function to add the pic/link to product details and another function to add the product details on a separate page?

I have already tried WooCommerce; however, I basically want an online catalog (with no ecommerce options). I tried a few different plugins to disable the ecommerce options, but they did not work. On the products page, I just ended up with a bunch of lines of code all over the page.

Here is the URL for reference: https://www.usaviation.aero/services/aircraft-sales/aircraft-for-sale/

With that being said, I have tried to create my own function but have not had any success. When I tried to find more information on how to do it, I ended up hopelessly confused. Does anyone out there know how I can set this up?

Your help is much appreciated.
