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.
