In this tutorial I will share the tutorial how to use eloquent database system, for you who are not familiar with this database system. Eloquent is a database system used by the laravel framework, but it's okay to use it outside laravel including in PHP Native and of course in Microframework Slim. for those of you who have never known, you can see it at https://laravel.com/docs/5.6/eloquent. there are so many advantages we can get by using eloquent. this database system may be your choice to use it in Microframework Slim. let's get started.
The first step we have to install Eloquent in our Slim application using the help of composer :
composer require illuminate/database
After finish installing Eloquent then we have to do the setting on our Slim application, I have an index.php file with this structure
[
'displayErrorDetails' => true,
'db'=>[
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'tutorial',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
]
]
]);
$container = $app->getContainer();
$container['view'] = function ($container) {
$view = new \Slim\Views\Twig( __DIR__ .'/templates', [
'cache' => 'path/to/cache'
]);
// Instantiate and add Slim specific extension
$basePath = rtrim(str_ireplace('index.php', '', $container['request']->getUri()->getBasePath()), '/');
$view->addExtension(new Slim\Views\TwigExtension($container['router'], $basePath));
return $view;
};
$container['db'] = function ($container) {
$capsule = new \Illuminate\Database\Capsule\Manager;
$capsule->addConnection($container['settings']['db']);
$capsule->setAsGlobal();
$capsule->bootEloquent();
return $capsule;
};
$app->get('/forum',function($request,$response,$args){
var_dump($this->db->table('berita')->get());
});
$app->run();
I have installed Twig as its templating, and using a routing system, to know the system templating and routing system, you can see it in the curriculum that I have created in the curriculum below.
Setting Database
$app = new Slim\App([
'settings' =>[
'displayErrorDetails' => true,
'db'=>[
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'tutorial',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
]
]
]);
This is a setting to connect to the database, we wrap all the keys and values into an array named 'db'=> [] :
'drive' => 'mysql''host' => 'localhost''database' => 'tutorial''username' => 'root''password' => ''We have made a setting to connect to our database, next to use our database in Slim application that we make, we must make it in a container. Still in the same index.phpfile, here is how make it:
$container['db'] = function ($container) {
$capsule = new \Illuminate\Database\Capsule\Manager;
$capsule->addConnection($container['settings']['db']);
$capsule->setAsGlobal();
$capsule->bootEloquent();
return $capsule;
};
$container['db'] :We create a key from container with db name, so later if we want to access function in container db, we will use it like this $this->db .
$capsule = new \Illuminate\Database\Capsule\Manager; : This is the namespace system of the eloquent package.
$capsule->addConnection($container['settings']['db']); : Connect the connections we have wrapped in the 'db' array, which is in the settings.
$capsule->setAsGlobal(); : Set Connection as Global , So you can access anywhere in the slim apikasi we have created.
$capsule->bootEloquent(); :To run eloquent
after finished creating the container, we can test whether the connection kedatabase we succeed, if successful then we will see the data residing in database. We can test in routing / forum.
$app->get('/forum',function($request,$response,$args){
var_dump($this->db->table('berita')->get());
});
$this->db->table('berita')->get() : Eloquent method to retrieve all data in the database . I will var_dump to see its results.
If not a mistake we will see the data in our database Tutorial appears in the routing /forum.
And I'll use a little eloquent method to pull data like a regular mysql query.
Display based on id we want :
$this->db->table('berita')->where('id',15)->get() : I will only show data only id 15.
We have successfully connected to the database in Slim framework and we have also used Eloquent in Slim. We have also made Eloquent in the Container so we can use Eloquent anywhere in the Slim application that we created, Just so many tutorials this time, may be useful and I hope you keep trying to get to know other Eloquent functions, Thank you :)
