Details:
A “Code” page/section allows web programmers who know php, to enter
specialised, customised php code for a page, from scratch.
A code section is supposed to contain php code, and will cause errors if it
contains just plain html, or plain text!
The Code Editor contains a simple text area, where the php code can be typed.
Simply enter the code in the text area, as desired, and click the “Save” button when
ready. To go back to Admin->Pages without saving, click “Cancel”.
You are neither required nor allowed to use an opening “<?php”, nor a
closing “?>”.
If you use opening and closing php tags in your code – for instance, to intermix
your php code with straight html - they will be removed when saving, and will
cause an error when the page is viewed!
