it is essential to manage user data efficiently to personalize the experience

00:00:10

and enhance performance.

00:00:12

Name formulas represent a recent and powerful feature

00:00:16

that allows you to define calculated expressions

00:00:19

once and reuse them throughout the application.

00:00:23

Unlike traditional variables,

00:00:25

name formulas are immutable and automatically recalculate when needed,

00:00:29

greatly simplifying maintenance and improving the app's responsiveness.

00:00:34

In this tutorial,

00:00:35

you will learn how to use name formulas

00:00:37

to retrieve information about the logged in user,

00:00:39

such as their name,

00:00:41

email address,

00:00:42

and profile picture.

00:00:44

We will focus on simple and practical examples

00:00:47

to ensure ease of understanding.

00:00:51

To access information about the logged in user,

00:00:54

a specific data source must be added to the application.

00:00:58

In Power apps on the left-hand panel,

00:01:00

click on data,

00:01:02

then click Add Data Source.

00:01:05

In the search bar,

00:01:06

type Office 365 users,

00:01:09

select the suggested connector,

00:01:11

and if prompted,

00:01:12

sign in using your work or school credentials.

00:01:16

This connection enables your application

00:01:18

to automatically query your professional account

00:01:21

to obtain the necessary data without requiring complex configurations.

00:01:26

The next step involves creating name formulas

00:01:29

that will fetch the user's profile information.

00:01:32

In the application tree view,

00:01:34

select the app object,

00:01:36

then in its properties,

00:01:37

choose formula.

00:01:40

This is where you will centrally write your formulas,

00:01:43

so they can be used throughout the application without code duplication.

00:01:47

The first formula to create is the following.

00:01:51

The name FAX current user is used here as an example,

00:01:55

but you may choose a different name if you prefer.

00:01:58

This formula uses the Office 365 users,

00:02:02

my profile function to retrieve all the details of the currently logged in user.

00:02:07

These include the full name,

00:02:09

professional email address,

00:02:10

phone number,

00:02:11

and other useful properties to personalize the application.

00:02:15

Next,

00:02:15

you need to add a second formula.

00:02:19

Similarly,

00:02:20

FX user photo is a suggested name that you

00:02:22

are free to adapt based on your naming conventions.

00:02:25

This formula allows access to the user's profile picture.

00:02:29

It uses the Office 365 user user Photo V2 function,

00:02:34

which requires the user's unique identifier to retrieve the image.

00:02:39

Instead of making a new complete request to Office 365,

00:02:43

this formula leverages the already available identifier via FX current user,

00:02:48

which optimizes the application's overall performance.

00:02:53

Thanks to these two formulas,

00:02:55

both the user data and their photo

00:02:58

will be accessible throughout your application

00:03:00

without requiring any additional action.

00:03:04

Once the formulas are created,

00:03:06

you can use them to display the logged in user's information on your main screen.

00:03:10

To do this,

00:03:12

insert a text control and use the formula FX current user.

00:03:16

display name

00:03:17

to display the full name.

00:03:20

Add a 2nd text control and refer to FX current user.mil

00:03:25

to display the email address.

00:03:29

Finally insert an image control

00:03:32

and set its image property to FX user photo

00:03:35

to display the profile picture.

00:03:38

All user information will then automatically

00:03:40

appear when the application is launched.
