The knowledge base has this page explaining how to add new page.

It works fine if I only put html contents in the page, but would there be
any way to put php code in the new page?

For example, if I put

<?
echo "hello world";
?>

in the body.tpl, then I get an internal error on the new page. Putting
the same code in the viewer, at the end of the file, gives what I expect. However, if I put

<?
$a="hello world";
echo $a;
?>

instead, then the entire site gets messed up. Would anyone know how to achieve this? Thank you in advance.

All php code goes to classes files. You can't put any of it in the templates. If you need something on the page to show dynamically you have to make a call to the class file from the template which will return whatever you need to show.
There are other examples in the KB to show you how to do this

Thank you for pointing me to KB examples. I tried to follow http://kb.x-cart.com/display/XDD/Working+with+viewer+classes and it goes fine if I add

protected function myVariable()
{
return "Hello World!";
}

to the viewer class. However, instead, if I write

protected function myVariable()
{
$mynewvariable="Hello World!";
return $mynewvariable;
}

then the entire site gets messed up. So, I reformulate my question: would there be a way to use variables in the codes for added pages?

The above change should not cause any errors. Please check the syntax (you might miss a letter) and make sure that quotes are " and ' (sometimes when you copy the source code from a website quotes become wrong characters).

Do you see any error messages in log files that are located in the var/log/ directory?

Oh, thank you very much. According to php_errors.log, I must have put
'' '' (twice single quotes) instead of " " (once double quotes)

Next time, I will check log files before posting here asking for answer, promised.
