Re: PHP and PostgreSQL question on identifier limits.

Hi,

> $sort || $sort="field1";

First of all I don't feel very comfortable with this exotic syntax, but
this is not the right place to discuss about it ;)

> $query="SELECT
> field1 AS \"<a href=$PHP_SELF?sort=field1>field1</a>\",
> field2 AS \"<a href=$PHP_SELF?sort=field2>field2</a>\",
> field3 AS \"<a href=$PHP_SELF?sort=userid>field3</a>\"
> FROM my_table ORDER BY $sort";

> $tbl=new Table($query);
> $tbl->print();

Is there a good reason why you don't add hyperlinks inside your Table
class, instead than using column names for such a purpose?

P.S.
Handling column sorting like you're doing is a big security risk! I hope
you are doing some more checks on $sort, otherwise SQL injection attacks
would be very easy to do.
