A lil typo in the explanation of the code.
Should say
$xoopsTpl->assign('xoops_showrblock', 0); // 1 display right blocks
$xoopsTpl->assign('xoops_showlblock', 0); // 1 display left blocks
Just make the 0 a 1 and you have side blocks. Northern is right. This is the defacto standard for adding content without the help of a module. The only drawback is it can't be searched by XOOPS because the content is not in the database. Also you will need to update the pages manually one-by-one if you need to change them in the future.
Give this module a try...
Happy searchIt uses google search and should pick up the wrapped custom pages very well. As long as you have displayed the links to the custom page so google can find them.
