It's easy to make a new template that you can pick for certain pages on your WordPress blog.
- Write the code you want for your new page. If you want to keep the same general look of the other pages and just make a small change, you can start with page.php (which should be in www/blog_name/wp-content/themes/theme_name/)
- at the very top of your file add <?php /* Template Name: Your New Template Name */?>
- Put the new file (make sure and name it something unique ex: newtemplate.php) in the same directory as you found page.php
- All done. Now go into the Admin -> Pages ->Quick Edit the page and pick the new template in the Template drop down and then Update. Easy!
