Magento

I would like to display the customer’s first name only in the welcome message created when $this->getWelcome() is called.  Example: ‘Welcome, Jon!’ instead of ‘Welcome, Jon Smith!’
I did some searching on this site and in the core files of Magento and I was unable to determine the method that needs to be called or parameter that needs to be given to just return the first name of a customer for the given session.  Any help with this question is much appreciated.

Also, is there any documentation available for the general core Magento API?  If not, is there any plan in place to make them available in the future?

Thank you,
Josh

My first ever answer to a question

You need to go to:
app/code/core/mage/page/block/html/header.php

The code that generates the message is on line 62:

Change getName to getFirstname

Thanks for the snippet of code.  Worked like a charm.

I’d like to note that all the variables provided by blocks core code are optional, and this could be achieved without changing core files by embedding this code directly in the template instead of reference to block’s provided variable:

Thanks Moshe

That’s really useful info.

Just a small typo:

getFirstName in your code should be getFirstname

Then it all works perfectly.
