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. 0:00 By using the symfony HTTP foundations package, 0:05 we not only have access to flash messages in the session, we also have 0:09 an easier way to access the cookie on the request and response objects. 0:14 Cookies work a little differently than sessions. 0:19 For this session, we just need to turn on sessions and 0:23 then we can read and write a session variable at any point in our script. 0:26 For cookies, first, 0:31 we need to create a cookie with all the details we wish to set, and 0:32 then we must send that cookie to our browser by passing it through a response. 0:36 Let's see how this works in our application. 0:41 We're saving user data in the functions_auth file, 0:44 under the saveUserSession function. 0:47 Well let's start here, we aren't going to modify anything right now. 0:50 We're just going to add some cookies. 0:54 To create a cookie, we'll use the cookie class from the symphony package 0:57 that we already included in this application. 1:01 We'll add a new cookie and 1:04 we'll set it equal to 1:09 new\symfony\component httpfoundation\cookie 1:12 The two required pieces of information are the cookie name and the value. 1:24 We'll start with our auth_user_id. 1:29 We'll set this equal to our auth_user_id above. 1:35 There we go, now let's copy this cookie and 1:52 we'll make a second cookie named auth_roles, 1:57 And set this to the role_id. 2:05 Now we can name the cookie, cookieID and cookieRoles. 2:09 Now that we have our cookies, we're ready to pass them through a response. 2:15 We can do this on our redirect, but 2:20 we'll need to adjust the redirect function to add those cookies to our header. 2:22 In the settings file, We'll 2:28 scroll down to our redirect, and we'll add a new parameter. 2:32 This optional parameter will be in array of extra details we want to accept. 2:37 So we'll name it extra and we'll set it equal to an empty array. 2:42 Next we need to add these cookies to our response. 2:46 So after the response, we'll check if key_exist, 2:49 Cookies in our extra array. 2:57 Since we're passing multiple cookies, 3:06 we want to add each of those cookies to our headers. 3:08 We can use a foreach extra Cookies as cookie, 3:11 And then we'll modify our 3:23 response to add response headers 3:27 setCookie equal to our cookie. 3:33 Finally we're ready to pass our cookie to our redirect. 3:38
