Adding pages to WP Template

Greyhat, did you read all that stuff I’ve linked? I mean before “trying again”. I am afraid you didn’t have the chance. You’ll find all the asnwers there.

Nothing HAS to be listed in your sidebar. You wouldn’t need a link to it, per se. However

I’d like to add another page inside the template, specifically one with a form and processing for a “email this to a friend” type link on each entry

was how you started this thread. Therefore, we have nothing else to go on. It sounds like you might be better served creating a plugin that does the funtion you want, and being able to call the function within an existing template, such as your index.php

Then you have been directed to the correct area of the codex. If it is in themes/mytheme, it is a template. Period. Be it a page template, or your index.php file, all the files in that directory are called templates. So looking at the codex in those areas is where you want to be.
http://codex.ww.wp.xz.cn/Template_Tags
All the WP specific “commands” that can be used in a template, or as you are saying “get things out of WordPress”.

No, what was too much to ask was for you to clearly explain your question, if the information provided didn’t genuinely answer your question. You asked what you needed to do to create a php file in your themes/mytheme directory. You were directed to the correct area of the codex to explain the process.
If you are asking something else, then by all means, clarify your position.

Just so we are getting on the same page
http://trac.ww.wp.xz.cn/file/trunk/wp-content/themes/default/page.php
that link is to the default page template. You could take that, and add your own php, or you can use a plugin, such as PHP Exec

Which will allow you to use a page template, and put the code directly into the page using the write page feature in the admin area.
The other option that was mentioned, was to create a plugin, which is also a php file, that would allow you to call that function within a template.

I give up. You are not following, so either someone else will find a way to explain to you that pages.php can be anything you want it to be, and can be called anything you want. It can have <?php get_header(); ?> at the top, and <?php get_footer(); ?> at the bottom, with your code and any template tags you want to include.
You can also use the plugin I showed, which would allow you to have a quicktag <phpcode>, and insert your php code via the write page.
