For Example: app/code/local/CompanyName/ModuleName/Block/Adminhtml/ModuleName/Edit/Tab/Form.php

Add the following code:

$dateFormatIso = Mage::app()->getLocale()->getDateTimeFormat(Mage_Core_Model_Locale::FORMAT_TYPE_SHORT);
$fieldset->addField('start_date', 'date', array(
  'name'   => 'start_date',
  'label'  => Mage::helper('events')->__('Start Date'),
  'title'  => Mage::helper('events')->__('Start Date'),
  'image'  => $this->getSkinUrl('images/grid-cal.gif'),
  'input_format' => $dateFormatIso,
  'format'       => $dateFormatIso,
  'time' => true
));

The key things to make it work are the “input_format”, “format”, and “time” parameters in the addField array. Setting the “time” variable to “true” makes the time input fields appear in the date selector pop-up.

Developing code locally on your computer has some major benefits over using a web server. For one, it’s usually faster as you don’t have to wait for your file changes to upload to the web.

I’ll be using WampServer, a program that lets you run a local web environment (Apache, PHP & MySQL)

You’ll need to download & install WampServer before continuing with this tutorial.

This tutorial assumes WAMP is installed under C:\wamp. You may change this path to reflect your own installation if it differs.

Step 1: Create the folder which will hold your subdomains

For example. Create the following folder

C:\wamp\www\subdomains

Each folder contained within the subdomains folder will essentially become a subdomain. For example:

example.localhost.com will point to C:\wamp\www\subdomains\example\

Step 2: Configuring Apache VirtualHosts

1) Enable the alias_module and vhost_alias_module for apache.

Doing this will enable virtualhost aliasing in apache for your subdomains.

2) Open C:\wamp\bin\apache\Apache2.2.21\conf\extra\httpd-vhosts.conf

3) In the httpd-vhosts.conf file, you’ll most likely see some example data.  Replace everything with the following:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName localhost.com
    ServerAlias www.localhost.com
    DocumentRoot "C:\wamp\www"
    ErrorLog "logs\errors.log"
    <directory "C:\wamp\www">
        Options Indexes FollowSymLinks
        AllowOverride all
        Order Deny,Allow
        Deny from all
        Allow from all
    </directory>
</VirtualHost>

<VirtualHost *:80>
    ServerName localhost.com
    ServerAlias *.localhost.com
    VirtualDocumentRoot C:\wamp\www\subdomains\%1
    ErrorLog "logs\errors.log"
    <directory "C:\wamp\www\subdomains\%1">
        Options Indexes FollowSymLinks
        AllowOverride all
        Order Deny,Allow
        Deny from all
        Allow from all
    </directory>
</VirtualHost>

Each <VirtualHost> tag contains a host definition.   The asterisk in <VirualHost *80> tells apache that any IP address can be used to access this host definition.  If you wanted to restrict it to just your computer, you could do <VirtualHost 127.0.0.1:80>

ServerName
ServerName localhost.com
The domain.  I use localhost.com. Just remember that whatever you choose to use will essential replace any real domains (EX: using google.com will not let you access the real google.com later)

ServerAlias
ServerAlias *.localhost.com
An alternate domain alias (usually www.localhost.com)

DocumentRoot
DocumentRoot "C:\wamp\www"
The absolute directory to your domain’s root (accessed by going to localhost.com)

ErrorLog Path to your error log.  This is optional.
ErrorLog "logs\errors.log"

VirtualDocumentRoot
VirtualDocumentRoot C:\wamp\www\subdomains\%1
The absolute directory for your subdomain, with a wildcard to define the subdomain’s name.  I use a wildcard %1 to get the name of the subdomain. example.localhost.com will point to C:\wamp\www\subdomains\example

<directory ________>
<directory "C:\wamp\www">
<directory "C:\wamp\www\subdomains\%1">
The directory permission definitions. Defined twice for both localhost.com and it’s virtual subdomains.

4) After making the changes to your httpd-vhosts.conf file, you must restart apache for the changes to take effect. Just click the WAMPSERVER icon in your Notification Area and choose “Restart All Services”.

Step 3: Updating Windows Host File

In order for you to access your localhost.com or example.localhost.com, you must first point these domains to your local IP address.  Windows unfortunately does not allow you to use a wildcard in the hosts file.  You will have to input each new subdomain into your hosts file for it to work in your browser.

1) Open C:\Windows\System32\drivers\etc\hosts using Notepad

2) Add a the following line to the bottom of your hosts file.

127.0.0.1       example.localhost.com

127.0.0.1       localhost.com
127.0.0.1       www.localhost.com
127.0.0.1       example.localhost.com
127.0.0.1       example2.localhost.com
127.0.0.1       mysubdomain.localhost.com

Test! Check if your subdomains work.

Open your browser and go to your local subdomain: example.localhost.com

Apache should now be serving files for that subdomain from C:\wamp\www\subdomains\example

Additionally: Custom Domain Definitions

If you ever wanted to create a custom domain definition that pointed to a folder outside of your “subdomains” folder, you can do that! Just open your httpd-vhosts.conf file (See step 2.2), and paste the following directly after NameVirtualHost *:80 and before the first instance of <VirtualHost *:80>.

This custom definition MUST be before your wildcard VirtualHost definition to work.

<VirtualHost *:80>
    ServerName mycustomlocaldomain.com
    ServerAlias www.mycustomlocaldomain.com
    DocumentRoot "C:\Documents\mycustomlocaldomain.com"
    ErrorLog "logs\errors.log"
</VirtualHost>

And how the httpd-vhosts.conf should finally look with this custom definition:

NameVirtualHost *:80

<VirtualHost *:80>
    ServerName mycustomlocaldomain.com
    ServerAlias www.mycustomlocaldomain.com
    DocumentRoot "C:\Documents\mycustomlocaldomain.com"
    ErrorLog "logs\errors.log"
</VirtualHost>

<VirtualHost *:80>
    ServerName localhost.com
    ServerAlias www.localhost.com
    DocumentRoot "C:\wamp\www"
    ErrorLog "logs\errors.log"
    <directory "C:\wamp\www">
        Options Indexes FollowSymLinks
        AllowOverride all
        Order Deny,Allow
        Deny from all
        Allow from all
    </directory>
</VirtualHost>

<VirtualHost *:80>
    ServerName localhost.com
    ServerAlias *.localhost.com
    VirtualDocumentRoot C:\wamp\www\subdomains\%1
    ErrorLog "logs\errors.log"
    <directory "C:\wamp\www\subdomains\%1">
        Options Indexes FollowSymLinks
        AllowOverride all
        Order Deny,Allow
        Deny from all
        Allow from all
    </directory>
</VirtualHost>
