magento - create a global function

Question

I want to create a function that can be accessed by all *.phtml files. Where should i place this function in the magento framework?

Answer 1

For down and dirty things, you can always define it in index.php. for example, I always put this function there:

function dumpit($obj)
{
  print '<pre>';
  print_r($obj);
  print '</pre>';
}

Then you can quickly call this routine from anywhere, without having to remember all the other overhead function names to get at the helper.

Answer 2

You should create a module and a helper class in that module (Usually MyCompany_Mymodule_Helper_Data by default). Then, add your function to that helper class. You can get to that function in your PHTML like this:

Mage::helper("mymodule")->someFunction();

Hope that helps!
