Magento is a very large eCommerce package and therefor you easily get lost in the code. We do Magento themes a lot and below you will find a few of our developers most-used code snippets.
Load a static block from the admin in your theme. First add this piece of XML to your cms.xml for example.
<block type="cms/block" name="static_block_name"> <action method="setBlockId"><block_id>static_block_name</block_id></action> </block>
If you have made the reference in the theme XML you are now able to get the output from the static block in your .phtml file like this.
Format a price integer to a money format including currency symbol.
Mage::helper("checkout")->formatPrice(15.99); // Use cart subtotal on cart.phtml Mage::helper("checkout")->formatPrice($this->getSubtotal());
Get the price block including sales etc. on a catalog product page.
