Prestashop - Increasing State ISO-Code Length

I believe that many Prestashop users has issue when inserting ISO Code for state due to the character length. Some countries accept 4 character state ISO Code. However, for certain countries like Malaysia, there are 5 character state ISO Code. Hence, I created this random post for solving this problem, guiding you how to increase ISO Code character.

Let's start the action.
Step 1: Update PS_STATE In SQL Database
i. Go to Database in PhpMyAdmin
ii. Search for ps_state
iii. Go to Structure Tab
iv. Select ISO Code and click on Change
v. Insert 5 to Length/Value field and click Save

Step 2: Change The Length of ISO Code Length Validation
i.  Open /classes/State.php with your editor
ii. Go to line #46 (For version 1.4.7 & above)
iii. Change the following code from
protected  $fieldsSize = array('iso_code' => 4, 'name' => 32);
To protected  $fieldsSize = array('iso_code' => 5, 'name' => 32);

Step 3: Change The Regular Express of ISO Code
i. Open /classes/Validation.php 
ii. Go to line #310 (For version 1.4.7 & above)
iii. Change the following code from
static public function isStateIsoCode($isoCode)
 return preg_match('/^[a-z]{1,4}$/ui', $isoCode);
static public function isStateIsoCode($isoCode)
return preg_match('/^[a-z0-9-]{1,5}$/ui', $isoCode);

Step 4: Change The Length Input Textbox 
i. Open admin/tabs/AdminStates.php
ii. Go to line #120  (For version 1.4.7 & above)
iii. Update the size value

<input maxlength="5" name="iso_code" size="5" style="text-transform: uppercase;" type="text" value="'.htmlentities($this->getFieldValue($obj, 'iso_code'), ENT_COMPAT, 'UTF-8').'" /> <sup>*</sup>
'.$this->l('1 to 5 letter ISO code').' ('.$this->l('official list here').')

It is done now!
