i just bought more storage in the icloud storage, and it still shows that i’m out of iphone storage. How do i get more iphone storage so i can take more pictures, etc..

You can buy storage in iCloud, but that will not add any storage to your iPhone, which will never have more than it did when you bought it. The Related Article at the top of this page when you posted here explains the difference between iPhone storage and iCloud storage.

iCloud storage and phone storage are 2 different things. You cant increase the phone storage. You can move the pictures to iCloud.
