How do I submit multiple forms with one button

I have an Edit Profile Page which consists of up to 4 forms. How do I submit data from this forms in my template events from one submit event?

Just fetch the data from each input element. If you are using Blaze you might consider using Viewmodel (the package name is manuel:viewmodel, see viewmodel.org for great documentation). Viewmodel improves Blaze quite a bit and saves you loads of tedious work.
