Decoding Cookies

We have an off cookie being set on login, and removed on logout. 0:00 Now we need to switch our authentication to use this cookie instead of the session. 0:06 Let's create a helper function to make it easier to read the cookie properties. 0:12 Function DecodeAuthCookie(). 0:17 Cookie = json_decode(request() 0:28 cookies->get('auth') and 0:36 return $cookie. 0:44 Let's call this new function on our homepage. 0:48 We can remove those request and call decondeAuthCookie. 0:54 Now let's go back to the browser. 1:03 Great, we can see both the auth, user ID and the auth roles. 1:06 But what if we just want to grab the user ID? 1:11 Let's go back to the function. 1:14 We're going to accept a new optional argument. 1:19 Prop = null. 1:24 Then we're going to check if, $prop === null, 1:29 Then we're just going to return the cookie. 1:41 Next, we want to check if 1:45 (!isset($cookie->$prop)) then 1:50 we'll return false. 1:59 And finally we can return 2:03 the cookie $prop. 2:08 Four conditionals. 2:12 First we check if the property is null. 2:13 If so we're returning the whole cookie. 2:16 Next, if we have a property, we're going to check if the cookie has that property. 2:19 If not, we're going to return false. 2:24 And finally, if both of those paths we have an actual property on our cookie so 2:27 we will return that single property. 2:33 Now let's go back to our homepage. 2:36 And to our decodeAuthCookie, we'll add auth_user_id. 2:39 Now we can go back to the browser. 2:45 And now, in the browser, we see only the user ID. 2:50 Let's clean up the homepage. 2:54 We'll remove the var_dump and then we can close the index.php. 2:59 Now we're ready to use this new decode auth cookie. 3:05
