API and form processing
I'm trying to build my first app for a project. Part of this requires a form to be added to a page for visitors to complete. I'm getting on OK but i'm struggling to figure out just how I go about actually saving the submitted form data into the app database table. Is there a specific method that does this? I can add the form to the page and can see the data being passed when the form processes, then I get lost.
I'm looking to save a text field and also an image field. When I look at the database I see that often data is stored in JSON format which makes me think I should be looking for a method that I can pass an encoded string to.
Any help or pointers appreciated. Also, is there an A to Z for the available api methods somewhere?
