Display Error Message for Custom Validation in Laravel 4

I have created a custom error function by creating a class;

<?php

class CoreValidator extends Illuminate\Validation\Validator
{
    public function validatePostcode($attribute, $value, $parameters = null)
    {
        $regex = "/^((GIR 0AA)|((([A-PR-UWYZ][0-9][0-9]?)|(([A-PR-UWYZ][A-HK-Y][0-9][0-9]?)|(([A-PR-UWYZ][0-9][A-HJKSTUW])|([A-PR-UWYZ][A-HK-Y][0-9][ABEHMNPRVWXY])))) [0-9][ABD-HJLNP-UW-Z]{2}))$/i";
        if(preg_match($regex ,$value)) {
            return true;
        }
        return false;
    }
}

I reference it in my model;

public static $rules = array(
        'first_name' => 'required|Max:45',
        'surname' => 'required|Max:45',
        'address_line_1' => 'required|Max:255',
        'address_line_2' => 'Max:255',
        'address_line_3' => 'Max:255',
        'town' => 'required|Max:45',
        'county' => 'Max:45',
        'postcode' => 'required|Postcode',
        'phone_number' => 'required|Max:22'
    );

It has been registered in my global.php;

Validator::resolver(function($translator, $data, $rules, $messages) {
        return new CoreValidator($translator, $data, $rules, $messages);
    });

It all works well, but the error message it returns is

validation.postcode

How/where do I set a custom error message for this?
I have tried setting app/lang/en/validation.php with (neither work);

'custom' => array(
        "validation.postcode" => "my error message 1",
        "postcode" => "my error message 2"
    )

P.S. I know that there is a regex validation method already, but this problem is more generic for me.

The code below also works perfectly, take note of the underscore on the index of the $customValidatorMessages array. Hope it helps someone :-)

class CoreValidator extends Illuminate\Validation\Validator
{
    /**
     * The array of custom validator error messages.
     *
     * @var array
     */
    protected $customValidatorMessages = array(); 

    public function validatePostcode($attribute, $value, $parameters = null)
    {
        $regex = "/^((GIR 0AA)|((([A-PR-UWYZ][0-9][0-9]?)|(([A-PR-UWYZ][A-HK-Y][0-9][0-9]?)|(([A-PR-UWYZ][0-9][A-HJKSTUW])|([A-PR-UWYZ][A-HK-Y][0-9][ABEHMNPRVWXY])))) [0-9][ABD-HJLNP-UW-Z]{2}))$/i";
        if(preg_match($regex ,$value)) {
            return true;
        }

        $this->customValidatorMessages['post_code'] = 'Postcode error message.';

        $this->setCustomMessages($this->customValidatorMessages);

        return false;
    }
}

You can use setCustomMessages() method to assign custom messages like the bellow code

<?php

class CoreValidator extends Illuminate\Validation\Validator
{

    private $custom_messages = array(
        "customvalidation" => "my error message.",
    );

    public function __construct($translator, $data, $rules, $messages = array(), $customAttributes = array())
    {
        parent::__construct($translator, $data, $rules, $messages, $customAttributes);
        $this->setCustomMessages($this->custom_messages);
    }

    public function validateCustomvalidation($attribute, $value, $parameters = null)
    {
        // validation code here
    }

}

If you want to utilize the custom validation messages array in app/lang/xx/validation.php, the correct way is as follows:

'custom' => array(
    'formFieldName' => array(
        'postcode' => 'error message for PostCode rule',
        'iamalwayslowercase' => 'error message for this rule'
    ),
),

Note that you use the name of the form field and then in the array you use the lowercased name of the rule.

From documentation:

In some cases, you may wish to specify your custom messages in a language file instead of passing them directly to the Validator. To do so, add your messages to custom array in the app/lang/xx/validation.php language file.

'custom' => array(
    'email' => array(
        'required' => 'We need to know your e-mail address!',
    ),
),

That means, in your case,

'custom' => array(
    'postcode' => array(
        'PostCode' => 'error message for PostCode rule',
        'required' => 'error message for required rule',
    ),
),

maybe this code more better :

// for example I am using sub-array custom at default validation file, but you can do it in other file as you wishes.
..other..
'custom' => array(
        'email' => array(
            'required' => 'We need to know your e-mail address!',
        ),
        "required"         => "Hey!!! don't forget at :attribute field is required.",
    ),
..other..

// you can determine your custom languages at your wishes file
$messages = \Lang::get('validation.custom');

Validator::make($input, $rules, $messages);

I think I have cracked it.

I added the message to the main array in app/lang/en/validation.php, not into the custom sub-array.

return array(
    ...
    "url" => "The :attribute format is invalid.",
    "postcode" => "my error message 2",
    ...
)

If this isn't the correct way, then someone is free to correct me.
