00:00:00,520 --> 00:00:09,450
The next step in our project is to create the logo dot P HP page create a new document and save the

2
00:00:09,450 --> 00:00:14,240
file as logout dot P. HP in your perfect cup directory.

3
00:00:17,490 --> 00:00:19,350
Now insert the following block of code

4
00:00:23,210 --> 00:00:23,590
here.

5
00:00:23,600 --> 00:00:31,330
We've cleared each session that we'd initially created and this is done using the UNset function so

6
00:00:31,330 --> 00:00:38,050
that the log in session variable f name and l name are all cleared once they're cleared we redirect

7
00:00:38,050 --> 00:00:42,110
the user back to the index dot p p page.

8
00:00:42,180 --> 00:00:48,450
We also pass along a variable called logout with the value set to true and you'll see why we do this

9
00:00:48,450 --> 00:00:50,990
in just a moment.

10
00:00:51,250 --> 00:01:03,520
Make sure you save any changes you made to this file and open your index DRP HP page.

11
00:01:03,550 --> 00:01:09,160
We want to create an alert notifying the user that they've been successfully logged out of the system

12
00:01:09,260 --> 00:01:13,720
and I'll show you an example on the completed Web site.

13
00:01:13,730 --> 00:01:21,090
This is the message we want to display and you'll see that it's position directly underneath the address.

14
00:01:21,120 --> 00:01:28,650
Here is the variable logout with the value set to true.

15
00:01:28,830 --> 00:01:47,100
So in order to do this you're going to insert the following block of code directly under the address.

16
00:01:47,140 --> 00:01:53,470
Here we first check to see if the variable logout is contained within our U.R.L. using the get method

17
00:01:55,560 --> 00:01:59,050
if the variable is found.

18
00:01:59,420 --> 00:02:06,450
We check to see if the value of the logout variable is equal to true and if the value is equal to true

19
00:02:06,690 --> 00:02:14,200
we display our alert message stating that the user has been logged out of the system.

20
00:02:14,320 --> 00:02:19,650
So I'm just gonna test this out now and when to refresh the blog that BHP page.

21
00:02:19,730 --> 00:02:23,780
So now it's asking me to log in and I'll just log in using one of the test accounts

22
00:02:34,250 --> 00:02:38,690
so we've been authenticated and it says Welcome Joel.

23
00:02:39,000 --> 00:02:41,820
And here's the logout link.

24
00:02:42,060 --> 00:02:50,210
So when you click logout and you can see that we have been logged out and here's the success message

25
00:02:51,350 --> 00:02:55,920
I'll try to go back to the blog just to verify that we had been logged out.

26
00:02:56,030 --> 00:03:03,060
So it did work because now it's asking me to log back in and so at this point you can go ahead and test

27
00:03:03,120 --> 00:03:05,220
out the log in function.
