I'm using Phalcon and his capability to make easier the translation with his Class Translate. So far I'm passing the t variable from the index to all the views, right when I set up volt, like this :
$view = new View();
$view->setViewsDir(WEBSITE_PATH.'/views/');
// Return a translation object
$view->t = new Phalcon\Translate\Adapter\NativeArray([
"content" => $localization
]);
That is working, but I also have pages to translate outside from the folder views, in .php, not .volt.
How can I share/set/pass this variable 't' to other places?
You can register the translations in your dependency injector like
$di->setShared('translations', function() use($di) {
// Include or set your translations here, must be an array
$translations = ['Phalcon' => 'Falcon', 'Word' => 'Translation'];
return new \Phalcon\Translate\Adapter\NativeArray(array(
'content' => $translations
));
});
Then you can call the translations in any controller like
$this->translations->_('Phalcon')
and in views like
<?=$this->translations->_('Word') ?>

I just started working with Laravel. I need to rewrite a whole system I made some years ago, using Laravel 4 as base framework. In my old system, I used to have a constant.php file with some constants declared, and a globals.php file which contained lots of array sets (for example, categories statuses, type of events, langs, etc.). By doing so, I could use something like
foreach ( $langs as $code => $domain ) {
// Some stuff
}
anywhere in my app.
My question is, how can I store that info in the so called "laravel way". I tried using some sort of object to store this info, setting this as a service and creating for it a facade:
app/libraries/Project/Constants.php
namespace PJ;
class Constants {
public static $langs = [
'es' => 'www.domain.es',
'en' => 'www.domain.us',
'uk' => 'www.domain.uk',
'br' => 'www.domain.br',
'it' => 'www.domain.it',
'de' => 'www.domain.de',
'fr' => 'www.domain.fr'
];
}
app/libraries/Project/ConstantsServiceProvider.php
namespace PJ;
use Illuminate\Support\ServiceProvider;
class ConstantsServiceProvider extends ServiceProvider {
public function register() {
$this->app->singleton('PJConstants', function() {
return new Constants;
});
}
}
app/libraries/Project/ConstantsFacade.php
namespace PJ;
use Illuminate\Support\Facades\Facade;
class ConstantsFacade extends Facade {
protected static function getFacadeAccessor() {
return 'PJConstants';
}
}
composer.json
"psr-4": {
"PJ\\": "app/libraries/Project"
},
and so I access that property as PJ\Constants::$langs.
This works, but I doubt it is the most efficient or correct way of doing it. I mean, is it the right way to "propagate" a variable by creating a whole Service Provider and facades and all such stuff? Or where should I put this data?
Thanks for any advice.
EDIT # 01
Data I want to pass to all controllers and views can be directly set in script, like in the example at the beginning of my post, but it can also be generated dynamically, from a database for example. This data could be a list of categories. I need them in all views to generate a navigation bar, but I also need them to define some routing patterns (like /category/subcategory/product), and also to parse some info in several controllers (Like get info from the category that holds X product).
My array is something like:
$categories = [
1 => ['name' => 'General', 'parent' => 0, 'description' => 'Lorem ipsum...'],
2 => ['name' => 'Nature', 'parent' => 0, 'description' => 'Lorem ipsum...'],
3 => ['name' => 'World', 'parent' => 0, 'description' => 'Lorem ipsum...'],
4 => ['name' => 'Animals', 'parent' => 2, 'description' => 'Lorem ipsum...']
]
Just as an example. Index is the id of the category, and the Value is info associated with the category.
I need this array, also, available in all Controllers and Views.
So, should I save it as a Config variable? How else could I store these data; what would be the best and semantically correct way?
For most constants used globally across the application, storing them in config files is sufficient. It is also pretty simple
Create a new file in the app/config directory. Let's call it constants.php
In there you have to return an array of config values.
return [
'langs' => [
'es' => 'www.domain.es',
'en' => 'www.domain.us'
// etc
]
];
And you can access them as follows
Config::get('constants.langs');
// or if you want a specific one
Config::get('constants.langs.en');
And you can set them as well
Config::set('foo.bar', 'test');
Note that the values you set will not persist. They are only available for the current request.
Update
The config is probably not the right place to store information generated from the database. You could just use an Eloquent Model like:
class Category extends Eloquent {
// db table 'categories' will be assumed
}
And query all categories
Category::all();
If the whole Model thing for some reason isn't working out you can start thinking about creating your own class and a facade. Or you could just create a class with all static variables and methods and then use it without the facade stuff.
For Constants
Create constants.php file in the config directory:-
define('YOUR_DEFINED_CONST', 'Your defined constant value!');
return [
'your-returned-const' => 'Your returned constant value!'
];
You can use them like:-
echo YOUR_DEFINED_CONST . '<br>';
echo config('constants.your-returned-const');
For Static Arrays
Create static_arrays.php file in the config directory:-
class StaticArray
{
public static $langs = [
'es' => 'www.domain.es',
'en' => 'www.domain.us',
'uk' => 'www.domain.uk',
'br' => 'www.domain.br',
'it' => 'www.domain.it',
'de' => 'www.domain.de',
'fr' => 'www.domain.fr'
];
}
You can use it like:-
echo StaticArray::$langs['en'];
Note: Laravel includes all config files automatically, so no need of manual include :)
Create common constants file in Laravel
app/constants.php
define('YOUR_CONSTANT_VAR', 'VALUE');
//EX
define('COLOR_TWO', 'red');
composer.json
add file location at autoload in composer.json
"autoload": {
"files": [
"app/constants.php"
]
}
Before this change can take effect, you must run the following command in Terminal to regenerate Laravel’s autoload files:
composer dump-autoload
For global constants in Laravel 5, I don't like calling Config for them. I define them in Route group like this:
// global contants for all requests
Route::group(['prefix' => ''], function() {
define('USER_ROLE_ADMIN','1');
define('USER_ROLE_ACCOUNT','2');
});
I think the best way is to use localization.
Create a new file messages.php in resources/lang/en (en because that is what is set in my config/app 'locale'=>'en')
return an array of all your values
return [
'welcome' => 'Welcome to our application'
];
to retrieve for laravel 5.3 and below
echo trans('messages.welcome');
or
echo Lang::get('messages.welcome');
for 5.4 use
echo __('messages.welcome')
laravel 5.0 localization
or
laravel 5.4 localization
Just to add to the above answer you will have to include the config class before you could start using it in Laravel 5.3
use Illuminate\Support\Facades\Config;
Atleast in Laravel 5.4, in your constructor you can create them;
public function __construct()
{
\Config::set('privileged', array('user1','user2');
\Config::set('SomeOtherConstant', 'my constant');
}
Then you can call them like this in your methods;
\Config::get('privileged');
Especially useful for static methods in the Model, etc...

Just put a file constants.php file into the config directory and define your constants in that file, that file will be auto loaded,
Tested in Laravel 6+
Create a constants class:
<?php
namespace App\Support;
class Constants {
/* UNITS */
public const UNIT_METRIC = 0;
public const UNIT_IMPERIAL = 1;
public const UNIT_DEFAULT = UNIT_METRIC;
}
Then use it in your model, controller, whatever:
<?php
namespace App\Models;
use App\Support\Constants;
class Model
{
public function units()
{
return Constants::UNIT_DEFAULT;
}
}
So, i am new in Zend Framework, i installed ZfcUser and i want when the user is not logged to didn't access to some routes for example : /blog/article/add,
actually i use <?php if($this->zfcUserIdentity()) :?> to check if the user is logged but how can i redirect the user to my login route/user if is try to access to /blog/article/add,
so plz if someone has any idea i will be very appreciative :)
I disagree with the selected answer because it's not really practical to do these kind of things inside every action of every controller that you want to deny access to.
There are two big modules out there that are used for this task. The first one being BjyAuthorize and the other big one being ZfcRbac. Please check them out. ZfcRbac is my favorite (because i wrote documentation for it) but it requires PHP 5.4+
Simple Way:
in controller:
if (!$this->zfcUserAuthentication()->hasIdentity()) {
return $this->redirect()->toRoute('route_to_login',array('param' => $param));
}
Some more:
(after auth zfcuset will redirect you to previous controller)
in module.config.php
'controllers' => array(
'invokables' => array(
'zfcuser' => 'Application\Controller\UserController',
),
...
),
next copy file vendor\zf-commons\zfc-user\src\ZfcUser\Controller\UserController.php
to module Application (same folder as in module.config.php)
delete all function except authenticateAction
add:
use Zend\Session\Container;
and change
return $this->redirect()->toRoute($this->getOptions()->getLoginRedirectRoute());
to
$redirect_session = new Container('redirect');
$redirect = $redirect_session->redirect;
if($redirect!='')
{
unset($_SESSION['redirect']);
return $this->redirect()->toRoute($redirect, array('lang' => $lang));
}
return $this->redirect()->toRoute($this->getOptions()->getLoginRedirectRoute(),array('param' => $param));
and at last add in controller
use Zend\Session\Container;
...
if (!$this->zfcUserAuthentication()->hasIdentity()) {
$redirect_session = new Container('redirect');
$redirect_session->redirect = 'route_to_this_controller_action';
return $this->redirect()->toRoute('route_to_login',array('param' => $param));
}
I would like to connect to a second database with Yii at runtime. The database name would come from a database table after the user to login.
I saw in a tutorial I should do this:
$db2 = Yii::createComponent(array(
'class' => 'EMongoClient',
'server' => 'mongodb://127.0.0.1:27017',
'db' => $emp['database']
));
Yii::app()->setComponent('db2',$db2);
But in my controler when I access Yii::app()->db2 get the error:
Property "CWebApplication.db2" is not defined
What am I doing wrong?
The following works for me:
Yii::app()->mongodb->setActive(false);
Yii::app()->mongodb->setServer('mongodb://localhost:27017');
Yii::app()->mongodb->setDb('db1');
Yii::app()->mongodb->setActive(true);
UPDATED: Try, instead instance, pass configurations:
Yii::app()->setComponent( 'db2', array(
'class' => 'EMongoClient',
'server' => 'mongodb://127.0.0.1:27017',
'db' => $emp['database']
)
);
Or, you may create special index on params in configurations, such as:
...
'params' => array(
'db2' => null,
),
And the use Yii::app()->params['db2'] = $db2
From this comment:
My problem is not with the creation of the component. Soon after
creating if I access Yii::app()->db2 its works, but when I try to
access via another model or controller I get the error
I think you are setting this component only once somewhere, and then making subsequent requests to different controllers.
You need to put the code, somewhere it is being called EVERYTIME, on every Request. thats how PHP works, there is no "global application state"
by default Yii comes with protected/components/controller.php has base controller for the rest of the app.
my suggestion would be to put your code on the init() method of that controller, so that it always gets called.
You mentioned the database name comes from a table once the user logs in, so you need to save that value in the session, in other to be able to access it in the other requests:
<?php
// After login in
Yii::app()->user->setState('db_name', $db_name);
// in protected/components/controller.php
public function init()
{
if (!Yii::app()->user->isGuest) {
$db2 = Yii::createComponent(array(
'class' => 'EMongoClient',
'server' => 'mongodb://127.0.0.1:27017',
'db' => Yii::app()->user->getState('db_name')
));
Yii::app()->setComponent('db2',$db2);
}
}
Hope it helps, I am assuming many things here :)
i wanted to know in which file we can set common code, for example i wanted to set timezone to UTC, instead of putting same code in all controllers file is there any way to put the code once and it will be reflect in all files.
You may create your file in ''components'' folder. You can see this folder in "protected" folder.
Or you can write your code in controller.php
File path: webroot/protected/components/Controller.php
Can you please try to add the codes in bootstrap.php file
If you need to set the server time you can check here.It is a simple method
Change time zone
Use application params, ie:
// config part
return array(
// ...
'params' => array(
'myParam' => 123
)
// ...
);
// Then in app use
Yii::app()->params['myParam'] // Will return 123
You can also create your own params holder as component, ie:
// config part
'components' => array(
'myConfigs' => array(
'class' => 'ext.MyConfigs'
'myParam1' => 123,
'myParam2' => 'blah'
)
)
// Component in extensions
class MyConfigs extends CComponent
{
public $myParam1;
public $myParam2 = 'defaultValue';
}
// Then in app use it:
Yii::app()->myConfigs->myParam1 // will return 123
