MVC Helpers
Just as Leaf has a couple of built-in helpers, Leaf MVC also ships with a bunch of helpers to make your life easier. These helpers are available throughout your application and help you with common tasks like finding files and loading paths.
Loading app paths
Since Leaf MVC and Leaf API come with a robust structure out of the box, they also come with quick ways to reference files in these structures. For example, if you want to reference a file in your public
folder, you can use the PublicPath()
helper.
AppPaths()
This returns an array of all the paths in your application.
$paths = AppPaths();
$controllersPath = AppPaths('controllers'); // you can do this
$controllersPath = $paths['controllers']; // or this
If the path you are looking for doesn't have a helper function, you can use the AppPaths()
helper to get the path. Just make sure that the path is defined in your config/paths.php
file.
AppPaths('weirdPath');
assets()
This returns the path to your assets folder. You can pass in a file name to get the path to that file.
$asset = assets('css/main.css');
// -> public/assets/css/main.css
You can configure the path to your assets folder in your config/paths.php
file.
'assets' => 'public/assets'
ConfigPath()
This returns the path to your config folder. You can pass in a file name to get the path to that file.
$dbConfigFile = ConfigPath('db.php');
// -> config/db.php
CommandsPath()
This returns the path to your commands folder. You can pass in a file name to get the path to that file.
$command = CommandsPath('MainCommand.php');
// -> app/commands/MainCommand.php
ControllersPath()
This returns the path to your controllers folder. You can pass in a file name to get the path to that file.
$controller = ControllersPath('MainController.php');
// -> app/controllers/MainController.php
DatabasePath()
This returns the path to your database folder. You can pass in a file name to get the path to that file.
$database = DatabasePath('migrations');
// -> app/database/migrations
FactoriesPath()
This returns the path to your factories folder. You can pass in a file name to get the path to that file.
$factory = FactoriesPath('UserFactory.php');
// -> app/database/factories/UserFactory.php
HelpersPath()
This returns the path to your helpers folder. You can pass in a file name to get the path to that file.
$helper = HelpersPath('MainHelper.php');
// -> app/helpers/MainHelper.php
LibPath()
This returns the path to your lib folder. You can pass in a file name to get the path to that file.
$lib = LibPath('MainLib.php');
// -> lib/MainLib.php
MigrationsPath()
This returns the path to your migrations folder. You can pass in a file name to get the path to that file.
$migration = MigrationsPath('MainMigration.php');
// -> app/database/migrations/MainMigration.php
ModelsPath()
This returns the path to your models folder. You can pass in a file name to get the path to that file.
$model = ModelsPath('User.php');
// -> app/models/User.php
PublicPath()
This returns the path to your public folder. You can pass in a file name to get the path to that file.
$public = PublicPath('index.php');
// -> public/index.php
RoutesPath()
This returns the path to your routes folder. You can pass in a file name to get the path to that file.
$routes = RoutesPath('_auth.php');
// -> app/routes/_auth.php
SeedsPath()
This returns the path to your seeds folder. You can pass in a file name to get the path to that file.
$seed = SeedsPath('MainSeed.php');
// -> app/database/seeds/MainSeed.php
StoragePath()
This returns the path to your storage folder. You can pass in a file name to get the path to that file.
$storage = StoragePath('MainStorage.php');
// -> storage/MainStorage.php
ViewsPath()
This returns the path to your views folder. You can pass in a file name to get the path to that file.
$view = ViewsPath('index.leaf.php');
// -> app/views/index.leaf.php
Loading app config
There are some situations that may require you to load up your config files. For such situations, we've prepared a couple of helpers to help you load up your config files.
MvcConfig()
This returns an array of all the config files in your application.
$configs = MvcConfig();
$dbConfig = MvcConfig('db'); // you can do this
$dbConfig = $configs['db']; // or this
It also allows you to load up a specific config from the config file you pass in.
$config = MvcConfig('db', 'host'); // you can do this
$config = $configs['db']['host']; // or this
AppConfig()
This returns an array of all the config in your config/app.php
file.
$configs = AppConfig();
$debug = AppConfig('debug'); // you can do this
$debug = $configs['debug']; // or this
AuthConfig()
This returns an array of all the config in your config/auth.php
file.
$configs = AuthConfig();
$auth = AuthConfig('auth'); // you can do this
$auth = $configs['auth']; // or this
CorsConfig()
This returns an array of all the config in your config/cors.php
file.
$configs = CorsConfig();
$origin = CorsConfig('origin'); // you can do this
$origin = $configs['origin']; // or this
DatabaseConfig()
This returns an array of all the config in your config/db.php
file.
$configs = DatabaseConfig();
$host = DatabaseConfig('host'); // you can do this
$host = $configs['host']; // or this
MailConfig()
This returns an array of all the config in your config/mail.php
file.
$configs = MailConfig();
$host = MailConfig('host'); // you can do this
$host = $configs['host']; // or this
ViewConfig()
This returns an array of all the config in your config/view.php
file.
$configs = ViewConfig();
$host = ViewConfig('viewEngine'); // you can do this
$host = $configs['viewEngine']; // or this
View Helpers
View helpers are in charge of outputting your views.
view()
This method calls the render()
method of whatever view engine you are using. It takes in the name of the view you want to render and an optional array of data you want to pass to the view.
view('index', [
'name' => 'Leaf'
]);
The only issue here is that not all view engines directly output the view. For example, Blade and Twig return the view as a string. This means that you have to echo the view.
echo view('index', [
'name' => 'Leaf'
]);
To make this easier, Leaf MVC ships with a render()
method that calls the view()
helper and echoes the view.
render()
This method calls the view()
helper and echoes the view. It takes in the name of the view you want to render and an optional array of data you want to pass to the view.
render('index', [
'name' => 'Leaf'
]);
