Accepting the Vote3:45 with Alena Holligan
We will set the database to use a vote table which accepts a book id and a user id for the vote instead of adding a column to the book table for score. This will allow more control over user voting.
Next up is the actual procedure for the voting. 0:00 To do this, let's create a single file called vote.php in the procedures folder. 0:03 We need to start with our bootstrap file and pull a couple values. 0:18 $vote is going to = request()->get('vote'). 0:38 And then our $bookId = request()->get('bookId'). 0:50 Next we're going to use a switch statement for 1:01 stating which direction we're going to vote. 1:03 Case 'up', We're 1:20 going to vote($bookId, 1). 1:25 Case 'down', we're going to vote($bookId, -1). 1:35 And finally, we can redirect to the book's page. 1:50 $response = 1:56 \Symfony\Component\HttpFoundation\Respons- 1:59 e::create(null, 2:07 \Symfony\Component\HttpFoundation\Respon- se:: 2:22 HTTP_FOUND. 2:36 Then our location. 2:40 '/books.php'. 2:46 $response->send. 2:52 And then exit. 2:55 Now, let's give this a try in the browser. 2:57 Those arrows aren't in the right place, let's go take a look. 3:01 Sure enough, I forgot a div. 3:07 "media-left". 3:16 Great, now let's try the vote. 3:29 Awesome, our book voting system works. 3:34 We'll extend this as we move forward with our authentication system, 3:37 allowing a single user to vote only once for a book. 3:41
