I am using D7 and views for one of my projects. I have created a view that displays the name, age, role and orders of the user. I would like these things to displayed only for the logged in user. For instance user/1 should get his name,age,role and orders only, he should not be able to see the other's details. Similarly each and every user must be able to see their own details. I know i can use the uid from the url, but not sure how to achieve this.
