1. Eloquent Minus Laravel April 2014
2. Hi My name is David, ! I am a designer, developer, and all-around good guy. ! @davidhemphill
3. Why would you use Eloquent outside of Laravel?
4. 1. Existing codebase is not on Laravel ! 2. It’s a small project that doesn’t need the power ! 3. Get a taste of Laravel without the commitment
5. It’s really easy to get started.
6. Install Composer getcomposer.org
7. Install composer into your project
8. { "require": { "illuminate/database": "4.1.*@dev" } } Create a composer.json
9. $ composer install $ php composer.phar install
10. Pull in composer’s autoloader require_once('vendor/autoload.php');
11. In your existing codebase, create a ‘start.php’ file
12. <?php use Illuminate\Database\Capsule\Manager as Capsule; ! $capsule = new Capsule; ! $capsule->addConnection([ 'driver' => 'mysql', 'host' => $database['DB_SERVER'], 'database' => $database['DB_DATABASE'], 'username' => $database['DB_USERNAME'], 'password' => $database['DB_PASSWORD'], 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci' ]); ! $capsule->bootEloquent();
13. Pull in that start file require_once('start.php');
14. But first, here’s a real-life use case
15. Live Stream • Email-based logins (no user account) • Basic PHP Session handling • Needed to interface with an existing database table • Wanted a way to pull out users without a bunch of fuss. (I also wanted to use Eloquent outside of Laravel)
16. Just a simple class that extends Eloquent Create a Model
17. <?php namespace Circles; ! use Illuminate\Database\Eloquent\Model as Eloquent; use Circles\Session; ! class User extends Eloquent { protected $table = 'registrations'; protected $timestamps = false; ! public function isLoggedIn() { if ($session_logged_in = $_SESSION['session_logged_in']) { $session_id = $_SESSION['session_id']; $session_email = $_SESSION['session_email']; ! // Get the user with this email $user = User::whereEmail($session_email)->first(); ! return Session::whereUserId($user->id)->first(); } return false; } ! public function hasSession() { return $session = User::whereEmail($this->email) ->where('last_activity', '<', new DateTime) ->first(); } }
18. "autoload": { "classmap": [ "./lib", "./models" ], "files": [ "./helpers.php", "./config/database.php", "./config/config.php", "./start.php" ] }
19. <?php require_once('vendor/autoload.php'); use Circles\User as User; session_start(); // Do stuff...
20. Adding users at the conference
21. $email = validate($_POST[‘email’]); $user = new User; $user->email = $email; $user->save();
23. $user = User::whereEmail(‘hi@davidhemphill.com') ->first();
24. $user = User::find(1); $user->email = 'hi@carrots.com'; $user->save();
25. Why? Because you can. (and it makes life easier)
26. That’s it.
