自定义模块添加到购物车成功消息Magento

Question

In my custom module I want to show the add to cart success message. I have following piece of code in my .phtml file:

echo '<form action="/checkout/cart/add/product/'.$_product->getId().'/" method="get">'."\n";
$_attributes = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray( $_product );
echo '<div class="product-attribute-options">'."\n";
$_child_products = Mage::getModel( 'catalog/product_type_configurable' )->getUsedProducts( null, $_product );
foreach( $_child_products as $_child_product ):
    if( $_child_product->isSaleable() ):
        $_child_product_qty = Mage::getModel('cataloginventory/stock_item')->loadByProduct( $_child_product->getId() )->getQty();
        if( $_child_product_qty > 0 ):
            $_child_product_size_label = $_child_product->getResource()->getAttribute('size')->getFrontend()->getValue( $_child_product );
            $_child_product_size_val = Mage::getResourceModel('catalog/product')->getAttributeRawValue( $_child_product->getId(), 'size', Mage::app()->getStore()->getId() );
            echo '<button value="'.$_child_product_size_val.'">'.$_child_product_size_label.'</button>'."\n";
        endif;
    endif;
endforeach;
echo '<input type="hidden" class="super_attribute_val" name="super_attribute[145]" value="" />'."\n";
echo '</div>'."\n";
echo '<input type="hidden" name="qty" value="1" />'."\n";
echo '<div class="add-to-cart">'."\n";
echo '<button class="button btn-cart"><span>'.$this->__('Buy Now').'</span></button>'."\n";
echo '</div>'."\n";
echo '</form>'."\n";

On pressing Buy Now, it adds the product to the cart but I want to show the green success message on top as well.

EDITED

I was advised to call the following function:

function showMessage(txt, type) {
    var html = '<ul class="messages"><li class="'+type+'-msg"><ul><li>' + txt + '</li></ul></li></ul>';
    $('messages').update(html);
}

But considering my form, I am not sure where to call this function from. I have:

echo '<button class="button btn-cart"><span>'.$this->__('Buy Now').'</span></button>'."\n"; 

and on pressing the button it submits the form with action get.

Answer 1

I think this code could help you:

Mage::getSingleton(‘customer/session’)->addMessage("Your message");

Also, this answer could be interesting for you.

Maybe you need to use $this->getMessagesBlock()->getGroupedHtml(); in your template.
