Topic: Garfield & Dilbert Cartoons

[Ken (OP)]

We've changed the cartoons displayed at the bottom of the forum page, the daily Dilbert cartoon was turned off and the Garfield daily was turned on.  :bigteeth:




I edited the code that was originally posted on the TinyPortal site by Freddy and reused it for this Garfield feed. If you would like to see what the code looks like, here 'tis:

Code: [Select]

/*
A PHP block with code that accesses the Garfield RSS feed and returns
a set number of cartoons.
Original RSS feed code author unknown.

NOTE: Freddys original code was set for the Dilbert cartoon; it was
edited to display the daily Garfield cartoon by Ken. July 2010.
