Application ($app)

$app in a controller

$app = $this->app;

$app in a custom class

/** @var \Concrete\Core\Application\Application */
protected $app;
public function __construct(\Concrete\Core\Application\Application $app)
{
    $this->app = $app;
}
public function myMethod()
{
    $app = $this->app;
}

(create instances of custom classes with $app->make(\ClassName::class))

$app in other places

$app = \Concrete\Core\Support\Facade\Application::getFacadeApplication();

Superglobals

Direct access to PHP superglobals (that is, $_REQUEST, $_POST, $_GET, $_SERVER, $_FILES) should be avoided: concrete5 have a nicer way to work with them with the $request instance.

• instead of $_GET['key']: use $request->query->get('key')
• instead of $_POST['key']: use $request->request->get('key')
• instead of $_REQUEST['key']: use $request->get('key', $default = null)
• instead of $_SERVER['key']: use $request->server->get('key')
• instead of $_FILES['key']: use $request->files->get('key')

For more options check \concrete\vendor\symfony\http-foundation\ParameterBag.php

$request in a controller

$request = $this->request;

$request in a custom class

    $this->request = $request;
}
public function myMethod()
{
    $request = $this->request;
}

Different places for storing data

Database

Databse Table: Config

configNamespace	configGroup	configItem	configValue
my_package	front_end	show_header	1

FileSystem

File: application\config\generated_overrides\configNamespace\configGroup.php

return array(
    'configItem' => TRUE,
    'configItem2' => 2,
    'configItem3' => 'Hey!',
);

Different ways to read and write config values

1: Using a Package object

$packageObject = \Package::getByHandle('my_package');

//Database

//save config value
$packageObject->getConfig()->save('front_end.show_header', true);
//get config value
$showHeader = $packageObject->getConfig()->get('front_end.show_header');
//has config value
$hasShowHeader = $packageObject->getConfig()->has('front_end.show_header');
//set config value
//$packageObject->getConfig()->set('front_end.show_header'); //not working
//clear config value
//$packageObject->getConfig()->clear('front_end.show_header'); //not working


//FileSystem:

//save config value
$packageObject->getFileConfig()->save('front_end.show_header', true);
//get config value
$showHeader = $packageObject->getFileConfig()->get('front_end.show_header');
//has config value
$hasShowHeader = $packageObject->getFileConfig()->has('front_end.show_header');
//set config value
//$packageObject->getConfig()->set('front_end.show_header'); //not working
//clear config value
//$packageObject->getConfig()->clear('front_end.show_header'); //not working

2: Using a service provider

$key = 'configNamespace::configGroup.configItem';
$value = '5';
$default = -1;

//Database
$configDatabase = \Core::make('config/database');
$configDatabase->save($key, $value);
$configDatabase->get($key, $default);
$configDatabase->has($key);
//$configDatabase->set($key, $value); //not working
//$configDatabase->clear($key); //not working

//FileSystem:
$configFile = \Core::make('config');
$configFile->save($key, $value);
$configFile->get($key, $default);
$configFile->has($key);
//$configFile->set($key, $value); //not working
//$configFile->clear($key); //not working

3: Using Config

$key = 'configNamespace::configGroup.configItem';
$value = '5';
$default = -1;

//FileSystem:
\Config::save($key, $value);
\Config::get($key, $default);
\Config::has($key);
//\Config::set($key, $value); //not working
//\Config::clear($key); //not working

Helpers

$th->email($email); //Leaves only characters that are valid in email addresses (RFC).
$th->alphanum($string); //Leaves only characters that are alpha-numeric.
$th->entities($v); //always use in place of htmlentites(), so it works with different languages.
$th->decodeEntities($v); //Decodes html-encoded entities (for instance: from '>' to '>').
