app/code/local/StackExchange/FreeShipping/Model/Observer.php
- o observador que verifica se você está próximo do frete grátis
<?php
class StackExchange_FreeShipping_Model_Observer
{
public function checkFreeShipping($observer)
{
//if free shipping is not enabled, do nothing
if (!Mage::getStoreConfig('carriers/freeshipping/active')) {
return $this;
}
$quote = Mage::getSingleton('checkout/session')->getQuote();
//if there are no products in the cart, again, do nothing
if (count($quote->getAllItems()) == 0 ){
return $this;
}
//get the quote subtotal
$subtotal = $quote->getSubtotal();
//get the free shipping
$freeShippingValue = Mage::getStoreConfig('carriers/freeshipping/free_shipping_subtotal');
//check if the cart is below the free shipping amount
if ($freeShippingValue > $subtotal) {
Mage::getSingleton('checkout/session')->addNotice(
Mage::helper('stackexchange_freeshipping')->__(
'Your cart has the has the value of %s. In order to get free shipping you need to order for %s more',
'<span style="color:green">'.Mage::helper('core')->currency($subtotal, true, false).'</span>',
'<span style="color:red">'.Mage::helper('core')->currency($freeShippingValue - $subtotal, true, false).'</span>'
)
);
}
}
}
app/locale/en_US/StackExchange_FreeShipping.csv
- o arquivo de tradução.Você pode adicionar isso para cada idioma que possui:
"Your cart has the has the value of %s. In order to get free shipping you need to order for %s more","Your cart has the has the value of %s. In order to get free shipping you need to order for %s more"
É claro que mude o texto se quiser diferente.
Limpe o cache e experimente.
Você deverá ver agora no carrinho uma mensagem de aviso acima da tabela do carrinho com a mensagem
Your cart has the has the value of 34$. In order to get free shipping you need to order for 15$ more.
