putting php code into the editor and where it goes

This is going to sound harsh, but I really don’t mean it to sound like that. This is just a realistic answer to your question.

If you don’t know about coding or how WordPress works, it will be pretyt much impossible to throw things in to be where you want them to go. The system is realtively easy (compared to a lot of other CMS’s out there) but it’s still very flexible, which means that there’s no single spot to put in code changes. That’s why there’s never much indication of “where to put them in”, because they can be put in many different places depending on what you want to achieve yourself.

Unfortunately the answer is… take some time to learn and do some messing around to see what things do and where they can go. It does take some time.

If you have something in particular that you want to do but haven’t been able to figure out, let us know what it is. We will normally have a lot more chance of ansewring single real questions rather then trying ot answer a vague open-ended question like you’ve asked now.

Ipstenu-your answer was the most informative I have received to date on this question. I understand now they are files, but are worked with in an editor. Yes, I am new to this. However there are always things your told you have to add in this place or that. I Do NOT know about code, how to use it or put it. These things are advertized as not having to know these things.
When someone sounds all upity and trys not to with out readly reading and understanding what is being asked you end up with some very angry people who have no where else to turn.
How do you edit on the server? Never heard of that either. As I said, I came to WordPress because it was billed as not having to know how to do these things.
Thank you M Lane
