[Resolved] A Few Questions I Had
I am fairly new to the WordPress blogging system and so far, I must say that it is an impressive offering. However, in my few days worth of experience with WordPress I have come up with a few questions.
First, what does it mean when plugin installation instructions tell you to place the PHP function code within the “LOOP” of WordPress. What constitutes as the LOOP?
Secondly, I have noticed that many plugins require you to place a string of PHP within the main Index template or some other file. Is this considered “Hacking The Core Files” and if I upgrade WP in the future from 2.2 to whatever version that comes after, will all of these plugins that required a piece of PHP code to be inserted into a file be broken? Will I have to reinstall all of these plugins?
Thanks for the answers, and I am really impressed with WordPress thus far.
