Facades are supposed to live in global namespace. Try to use \Ajax::test() instead of Ajax::test in your controller, and see if it works. If it doesn't, your alias is not registering properly.

In my controller it work perfectly in both ways \Ajax::test() and simply Ajax::test() but is not working if I call it from my template file in this way {{ Ajax::test() }} or {!! Ajax::test() !!}

I'm also deleted the cache with php artisan cache command and also force to regenerate the compiled.php file that is inside the /vendor folder..but still nothing.

The alias is registered into the app.php file like any other Facade aliases.

any other ideas?

Right, you should also remove use App\Facades\Ajax\Facade\Ajax; from your controller.

Or, alternatively, try Ajax::test() in php artisan tinker console.

Ok..done already this test using tinker with two different facade defined in the same way..below the result:

Psy Shell v0.4.4 (PHP 5.5.9-1ubuntu4.9 — cli) by Justin Hileman
>>> Currency::test()
hello Currency⏎
=> null
>>> Ajax::test()
PHP Fatal error:  Class 'Ajax' not found in eval()'d code on line 1

both are in app.php aliases and also registered into the FacadeServiceProvider that is loaded into the app.php as showed above.

full FacadeServiceProvider code

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Facades\Currency\Currency;
use App\Repositories\Currency\CurrencyEloquent;
use App\Currency as CurrencyModel;
use App\Facades\Language\Language;
use App\Language as LanguageModel;
use App\Repositories\Language\LanguageEloquent;
use App\Facades\Helper\Helper;
use App\Facades\Ajax\Ajax;

class FacadeServiceProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot() {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register() {

        // Repository Facade
        $this->app->bind('currency', function($app) {
            return new Currency(new CurrencyEloquent(new CurrencyModel()), new LanguageEloquent(new LanguageModel()));
        });

        // Language Facade
        $this->app->bind('language', function($app) {
            return new Language();
        });

        // Helper Facade
        $this->app->bind('helper', function($app) {
            return new Helper(
                    $this->app->make('App\Repositories\Generic\GenericInterface'), 
                    $this->app->make('App\Repositories\Auction\AuctionInterface'), 
                    $this->app->make('App\Repositories\Lot\LotInterface'), 
                    $this->app->make('App\Repositories\Good\GoodInterface')
            );
        });

        // Ajax Facade
        $this->app->bind('ajax', function($app) {
            return new Ajax();
        });
        
    }

}

ideas?

Does the log file have a backtrace for the "Class not found" error?

The test :

class AjaxTest extends TestCase{
    //put your code here
    
    public function tearDown() {
        parent::tearDown();
        Mockery::close();
    }
    
    public function testTest(){
        \Ajax::shouldReceive('test')->withAnyArgs();
//      \Currency:shouldReceive('test')->withAnyArgs();       // WORK FINE
        
    }
    
}

The trace :

really don't know what to do..I check everything. I understand that for some reason this class is not instantiated by laravel but don't know why...Also look like any other facade I define are not working anymore..I'm gonna try to put the same code in a fresh project and see what happen! I'll let you know.

Ok..same code on different project and it work perfectly! what can I do? I can't rewrite all the code because is a big project...any ideas? thank you all..

Bloody file permissions!

I'm moving from Windows to Mac at the moment and this is a constant issue.

I'm actually looking at going on some kind of network admin course so I can get my head round this once and for all
