Working with Namespaces in the Fat Free framework

Question

I am trying to work with namespaces in Fat Free. Everything works fine, but when i ad the namespace, i get this:

Internal Server Error

Fatal error: Class 'Gadgets\iPad' not found

here is my code:

index.php

$f3=require('lib/base.php');

$f3->set('AUTOLOAD','ui/');

$f3->route('GET /', function(){

$obj=new Gadgets\iPad;

echo $obj->hallo('cat');

});

$f3->run();

ui/iPad.php

namespace Gadgets;

class iPad { 

    function hallo($word){ echo $word;}}

Thank you

Your class file should appear in the ui\Gadgets folder (full path: ui\Gadgets\iPad.php) in order for F3 to find and autoload it. See this answer for more details on F3's autoloader behaviour.

To answer your comment "i thought i have to use a namespace so i do not have to make a Gadgets folder", here are two points to keep in mind:

• namespaces are here to help you organize your code: store all the classes related to a common functionality into one same namespace.
• autoloader is here to help you organize your files: store one class per file and stop caring about require or include calls.

Both functionalities (namespaces/autoloader) are optional. Use them if you understand and need them.
