creating a zf2 module without controllers with some autoloaded classes

Question

I'm trying to create a Zend Framework 2 module that has some generic classes that I want to use in some of my controllers.

I created a directory called 'tux-drink-zf2-module' in 'vendor' directory.

I added that directory to 'application.config.php'.

my Module.php has the following:

<?php

namespace TuxDrink;

use Zend\ModuleManager\Feature\AutoloaderProviderInterface;

class Module implements AutoloaderProviderInterface
{
public function getAutoloaderConfig()
{
    return array(
        'Zend\Loader\ClassMapAutoloader' => array(
            __DIR__ . '/autoload_classmap.php',
        ),
        'Zend\Loader\StandardAutoloader' => array(
            'namespaces' => array(
                __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
            ),
        ),
    );
}
}

update

new:

my autoload_classmap.php has the following:

<?php
// Generated by ZF2's ./bin/classmap_generator.php
return array(
'TuxDrink\Module'                                  => __DIR__ . '/Module.php',

);

but still when I try to refresh my project I get the following error:

 Fatal error: Uncaught exception 'Zend\ModuleManager\Exception\RuntimeException' with message 'Module (tux-drink-zf2-module) could not be initialized.' in /Volumes/2g-storage/projects/php-projects/myalcoholist/vendor/zendframework/zendframework/library/Zend/ModuleManager/ModuleManager.php on line 144

maybe i'm missing some other files in order to properly configure this as a Module? remember, this is a package for sources, without controllers, views and actions.

any information regarding the issue would be greatly appreciated.

update

this issue was solved when i fixed the directories structure.

but when I'm trying to use the module in one the the controllers.

in my case i need to use two classes from the TuxDrink module.

class 'TuxDbMysqlDrink' and class 'TuxDbMysql'.

I need to use them in controller 'DrinkController' in action 'drink-brand-autocomplete'.

I use the following code:

use \TuxDb\Mysql\Drink\TuxDbMysqlDrink;

use \TuxDb\Mysql\TuxDbMysql;


public function drinkBrandAutocompleteAction() {
    $param=$this->getRequest()->getQuery('q');
    if ($param) {
        $drink = new TuxDbMysqlDrink();
        $result=$drink->autoCompleteDrinkBrand($param);
        return $result;
    }
}

and I get the following error message:

 Fatal error: DrinkManagement\Controller\DrinkController cannot use TuxDrink\TuxDb\Mysql\Drink\TuxDbMysqlDrink - it is not a trait in /Volumes/2g-storage/projects/php-projects/myalcoholist/module/DrinkManagement/src/DrinkManagement/Controller/DrinkController.php on line 197

any ideas?

tried to google, couldn't understand what it means "it is not a trait"

update

resolved it with this code:

public function drinkBrandAutocompleteAction() {
    $param=$this->getRequest()->getQuery('q');
    if ($param) {
        $drink = new \TuxDrink\TuxDb\Mysql\Drink\TuxDbMysqlDrink();
        $result=$drink->autoCompleteDrinkBrand($param);
        die(var_export($result,1));
     ...

Answer 1

Going by the error, the Module name is tux-drink-zf2-module . Taking sanitization into account, i'll assume your module is CamelCased like TuxDrinkZf2Module . Therefore the namespace you're assigning inside Module.php doesn't match, as it's only TuxDrink .

So my guess would be, either of your names is incorrect.
