Hello,

 

I need to do some customization to the CRUD. Basically i need to upload multiple files in an Add or Edit Action, and all i'm going to save in the database is the url of the folder that will contain the images.

 

I have been searching the forum, and it seems like I have to do this myself.

 

What i'm doing, is showing multiple upload buttons using the add_field_callbak, and so far so good.

 

The problem is that i also need some custom callback, to save the name and url of the uploaded files.

 

I've been reading the GroceryCRUD source code, and cant figure out how to use or create callbacks. I'm trying to use "call_user_func" for the callbacks, however, it doesn't work because each upload creates a new PHP request, and the variable that saves the user callback is empty in this context.

 

I was wondering if someone could explain me how do the GroceryCRUD callbacks work.

 

Thank you for your time.
