We will use the HTTP Foundations package to make it easier to set and retrieve cookies. First, we need to create a cookie with all the detail we wish to set, then we must send that cookie to our browser by passing is through with a response.
NOTE: Because we set our extra parameter to accept an array, make sure you pass the cookie as an array.
Tips for Reading and Writing Cookies
To test reading a cookie after login: on index.php
if (request()->cookies->has('access_token')) {
echo "logged in";
} else {
echo "not logged in";
}

Cookies can be a bit tricky to work with using only the built-in PHP functions.
-
0:05
By using the symfony HTTP foundations package,
-
0:09
we not only have access to flash messages in the session, we also have
-
0:14
an easier way to access the cookie on the request and response objects.
-
0:19
Cookies work a little differently than sessions.
-
0:23
For this session, we just need to turn on sessions and
-
0:26
then we can read and write a session variable at any point in our script.
-
0:31
For cookies, first,
-
0:32
we need to create a cookie with all the details we wish to set, and
-
0:36
then we must send that cookie to our browser by passing it through a response.
-
0:41
Let's see how this works in our application.
-
0:44
We're saving user data in the functions_auth file,
-
0:47
under the saveUserSession function.
-
0:50
Well let's start here, we aren't going to modify anything right now.
-
0:54
We're just going to add some cookies.
-
0:57
To create a cookie, we'll use the cookie class from the symphony package
-
1:01
that we already included in this application.
-
1:04
We'll add a new cookie and
-
1:09
we'll set it equal to
-
1:12
new\symfony\component httpfoundation\cookie
-
1:24
The two required pieces of information are the cookie name and the value.
-
1:29
We'll start with our auth_user_id.
-
1:35
We'll set this equal to our auth_user_id above.
-
1:52
There we go, now let's copy this cookie and
-
1:57
we'll make a second cookie named auth_roles,
-
2:05
And set this to the role_id.
-
2:09
Now we can name the cookie, cookieID and cookieRoles.
-
2:15
Now that we have our cookies, we're ready to pass them through a response.
-
2:20
We can do this on our redirect, but
-
2:22
we'll need to adjust the redirect function to add those cookies to our header.
-
2:28
In the settings file, We'll
-
2:32
scroll down to our redirect, and we'll add a new parameter.
-
2:37
This optional parameter will be in array of extra details we want to accept.
-
2:42
So we'll name it extra and we'll set it equal to an empty array.
-
2:46
Next we need to add these cookies to our response.
-
2:49
So after the response, we'll check if key_exist,
-
2:57
Cookies in our extra array.
-
3:06
Since we're passing multiple cookies,
-
3:08
we want to add each of those cookies to our headers.
-
3:11
We can use a foreach extra Cookies as cookie,
-
3:23
And then we'll modify our
-
3:27
response to add response headers
-
3:33
setCookie equal to our cookie.
-
3:38
Finally we're ready to pass our cookie to our redirect.
