Magento – Magento 2: Date in email template

In this case you need to rewrite the above specified class using your module. You can use this module. I love to call this module as Rkt_CustomerSPTemplateModifier

File : app\etc\modules\Rkt_CustomerSPTemplateModifier.xml

<config>
    <modules>
        <Rkt_CustomerSPTemplateModifier>
            <active>true</active>
            <codePool>local</codePool>
            <depends>
                <Mage_Customer />
            </depends>
        </Rkt_CustomerSPTemplateModifier>
    </modules>
</config>

This file tells to magento that, I am going to include a module Rkt_CustomerSPTemplateModifier in local code pool and it depends on Mage_Customer mdoule.

File: app\code\local\Rkt/CustomerSPTemplateModifier/etc/config.xml

<config>
    <modules>
        <Rkt_CustomerSPTemplateModifier>
            <version>1.0.0</version>
        </Rkt_CustomerSPTemplateModifier>
    </modules>
    <global>
       <models>
          <customer>
              <rewrite>
                  <customer>Rkt_CustomerSPTemplateModifier_Model_Customer</customer>
              </rewrite>
          </customer>
       </models>
    </global>
</config>

This configuration tells to magento that, it should use the custom class Rkt_CustomerSPTemplateModifier_Model_Customer whenever it requires to use Mage_Customer_Model_Customer.

Now we need to define our custom model class Rkt_CustomerSPTemplateModifier_Model_Customer. For this.

File : app\code\local\Rkt/CustomerSPTemplateModifier/Model/Customer.php

<?php

/**
 * Rewriting core class `Mage_Customer_Model_Customer`
 *
 * The methods which are defined inside this class will be used prior to those methods which are
 * defined inside the class `Mage_Customer_Model_Customer`.
 *
 */
class Rkt_CustomerSPTemplateModifier_Model_Customer extends Mage_Customer_Model_Customer
{

     /**
     * Send email with reset password confirmation link
     *
     * @return Mage_Customer_Model_Customer
     */
    public function sendPasswordResetConfirmationEmail()
    {
       $storeId = $this->getStoreId();
        if (!$storeId) {
            $storeId = $this->_getWebsiteStoreId();
        }
        $customVar = $this->getCustomvar();

        $customCollection= Mage::getModel('namespace_extension/customcollection')->load(5);

        $this->_sendEmailTemplate(
            self::XML_PATH_FORGOT_EMAIL_TEMPLATE, self::XML_PATH_FORGOT_EMAIL_IDENTITY,
            array(
                'customer' => $this, 
                'customvar' => $customVar, 
                'customcollection' => $customCollection
            ), 
            $storeId
        );

        return $this;
    }
}

That's it. A tiny module is successfully created. Now clear all caches and then try again.

First you need to understand how inline-css and non-inline-css work in magento.

For adding any inline-css using a separate file you define it using

{{inlinecss file="email-inline.css"}}

It will inject css defined in your file within style attribute of each tag with provided class.

So if you need to style button in your email, you need to define a class in email-inline.css like following:

.btn {

}

then you need to apply this class to an element in your template like following:

<input type="button" class="btn" />

Magento will automatically inject the css in style attribute before sending an email.
