00:00:00.650 --> 00:00:04.680
The final part of logging
in is a log out system.

2
00:00:04.680 --> 00:00:09.180
We've already covered all of this,
so it should not be anything new.

3
00:00:09.180 --> 00:00:11.800
We need to create a do log out procedure.

4
00:00:13.040 --> 00:00:15.175
Let's close up the ink folder.

5
00:00:17.171 --> 00:00:20.682
DoLogout.php.

6
00:00:26.194 --> 00:00:27.646
Require,

7
00:00:34.121 --> 00:00:39.909
Inc/bootstrap.php.

8
00:00:39.909 --> 00:00:44.170
Now, we're going to set the bad cookie and
then redirect.

9
00:00:44.170 --> 00:00:47.136
Let's go to our function and
copy these two lines.

10
00:00:53.437 --> 00:00:56.044
Now, let's change our navigation and

11
00:00:56.044 --> 00:00:59.289
check if the user should see the log in or
log out.

12
00:01:06.437 --> 00:01:11.280
If not is authenticated,

13
00:01:15.128 --> 00:01:20.060
When we're breaking up our conditional
statement over multiple code blocks,

14
00:01:20.060 --> 00:01:24.476
it can be easier to follow if we use
a secondary format using a colon and,

15
00:01:24.476 --> 00:01:25.001
and if.

16
00:01:34.148 --> 00:01:37.424
We can also add an else for
our log out link.

17
00:01:53.369 --> 00:01:56.494
Procedures/doLogout.

18
00:01:59.891 --> 00:02:05.086
Because we're using the is authenticated
function in our navigation file, we'll

19
00:02:05.086 --> 00:02:10.075
need to add the bootstrap file to the rest
of our login and register pages as well.

20
00:02:31.357 --> 00:02:33.900
We also need to clean up our home page.

21
00:02:38.067 --> 00:02:40.322
We'll move the bootstrap file to the top.

22
00:02:42.577 --> 00:02:45.120
And remove this extra logged in code.

23
00:02:49.798 --> 00:02:51.831
Let's take a look at this in the browser.

24
00:02:58.681 --> 00:03:01.530
While we're logged in,
we see the link to log out.

25
00:03:02.660 --> 00:03:07.740
And when we log out, we see the links
to log in or register again.

26
00:03:07.740 --> 00:03:12.690
Also, when we click on the Add Book,
we get redirected to the log in page.
