Wordpress Themes - WP Forum at BFA - How to put a Search form and format it in a page

Hi.

I need to insert a search form in a page and I have a couple of questions.

1. The "standard"

PHP Code:


		
			
<?php include (TEMPLATEPATH . '/searchform.php'); ?>

would not work. It gets scrambled upon saving the page.
Hover, this code works fine:

PHP Code:


		
			
<?php include ('wp-content/themes/atahualpa351/searchform.php'); ?>

2. I get a search input text field that is all the page wide. I know there is a way to personalise the way it looks (e.g. make it only 300 points wide, and so on) but I do not know how to do it....

PS I have tried several php executions plug-ins with the same results.

Thanks a lot!
