Hi @cmwwebfx
ACF has the acf_form() function that allows you to add the custom field inputs on the backend to the front end. Unfortunately, it needs you to click the save button to save the changes. If you want it to save automatically, I’m afraid you need to use AJAX and custom handler for the AJAX action. In this custom handler, you can use the update_field() function to update the custom field.
If you don’t have the idea how to do it, I suggest you hire a developer to help you out with it, and I’d recommend looking for one on https://studio.envato.com/ or https://www.upwork.com/.
I hope this makes sense.
