Using namespaces in Laravel 4 - php

Question

I'm new to Laravel and using PHP namespaces in general. I didn't run into any problems until I decided to make a model named File. How would I go about namespacing correctly so I can use my File model class?
The files are app/controllers/FilesController.php and app/models/File.php. I am trying to make a new File in FilesController.php.

Answer 1

Namespacing is pretty easy once you get that hang of it.
Take the following example:
app/models/File.php
namespace App\Models;
class File {
public function someMethodThatGetsFiles()
{
}
}
app/controllers/FileController.php
namespace App\Controllers;
use App\Models\File;
class FileController {
public function someMethod()
{
$file = new File();
}
}
Declare the Namespace:
namespace App\Controllers;
Remember, once you've put a class in a Namespace to access any of PHP's built in classes you need to call them from the Root Namespace. e.g: $stdClass = new stdClass(); will become $stdClass = new \stdClass(); (see the \)
"Import" other Namespaces:
use App\Models\File;
This Allows you to then use the File class without the Namespace prefix.
Alternatively you can just call:
$file = new App\Models\File();
But it's best practice to put it at the top in a use statement as you can then see all the file's dependencies without having to scan the code.
Once that's done you need to them run composer dump-autoload to update Composer's autoload function to take into account your newly added Classes.
Remember, if you want to access the FileController via a URL then you'll need to define a route and specify the full namespace like so:
Route::get('file', 'App\\Controllers\\FileController#someMethod');
Which will direct all GET /file requests to the controller's someMethod()
Take a look at the PHP documentation on Namespaces and Nettut's is always a good resource with this article

Answer 2

first, load your class with:
$ composer dump-autoload
then
$file = new File;
// your stuff like:
$file->name = 'thename';
$file->active = true;
$file->save();

Answer 3

To namespace your model, at the top of your model class right after the opening
Then when you call from controllers you will call new Whatever\Model;
You probably have to do a dump-autoload with composer the first time around.

Answer 4

have a look to it.. hopefully will clear your query....
<?php
namespace app\controllers;
use yii\web\Controller;
use app\models\users;
class UserController extends Controller{
public function actionIndex()
{
echo "working on .....";
}
}

Namespaces are defined at the top of PHP classes right after the opening php script tag like this:
<?php
namespace MyNameSpace;
When you then want to use the namespaced class in some other class, you define it like this:
new MyNameSpace\PhpClass;
or import it at the top of the file (after namespaces if present) like this:
<?php
//namespace
use MyNameSpace\MyPHPClass;
//then later on the code you can instantiate the class normally
$myphpclass = new MyPHPClass();
In Laravel namespaces can be defined anywhere composer can autoload them, I'd recommend defining namespaces within the app directory. So you can define a namespace like Utils for holding Utility classes by creating a Utils directory in the app directory, creating our utility classes and defining the namespace as we did above.
Afterwards you have run the command to ask composer to autoload classes:
$ composer dump-autoload
