Question

I have the following code in config:

<?php
return array(
    'di' => array(
        'instance' => array(
            'alias' => array(
                'sms_message' => 'Sms\Message',
            ),
            'sms_message' => array(
                'parameters' => array(
                    'from' => 'SENDER',
                ),
            ),
        ),
    ),
);

And in Message.php class I have a setter (I dont want to use contructor):

/**
 * From
 * @var string
 */
protected $from;

/**
* @param string $from
*/
public function setFrom($from)
{
    $this->from = $from;
}

But when I try to load it I get unconfigured object:

var_dump($this->getLocator()->get('Sms\Message'));exit;

object(Sms\Message)[596]
    protected 'to' => null
    protected 'from' => null
    protected 'body' => null

How do I can make it work?

For setter-injection you have to use the injections keyword:

array(        
    'di' => array(
        'instance' => array(
            'alias' => array(
                'sms_message' => 'Sms\Message'
            ),
            'Sms\Message' => array(
                'injections' => array(
                    'setFrom' => array(
                        'from' => 'SENDER'
                    ),
                ),
            ),
        ),
    ),
);

I’m not sure if the instance configuration is supposed to work with aliases. Better use the FQCN instead.

I also discovered that currently injections are not executed when requesting an alias while reproducing your example:

// The will call setFrom(...)
$di->get('Sms\Message);
// This will not call setFrom(...)
$di->get('sms_message');

I don’t know if this behavior is intended or not. (I’ll report this test which is currently failing)
