Re: Question Regarding Cookies, Sent Headers, and Functions That Return Values

Here is the code in a readable form (alterations for security, simplicity ...) if ((stristr($HTTP_SERVER_VARS["remote_address"],"XXX.YYY.ZZZ"))||($pwprotect== 'password')) { setcookie("pwprotect2","1",time()+300); } else { echo "<form>(ASK FOR PASSWORD)</form>"; } Now when you say "blank line" does that mean actual empty lines between the <? tag and the beginning of the code? ie <? if ((stristr(.... might cause problems? Seems kind of snarky, but I'm willing to try anything. Anyway, thanks for responding ... ON A COMPLETELY SEPARATE NOTE, does anyone here understand how the odbc_primarykeys() function ... err .. functions? Tried all avenues, kept getting an SQL Error in SQLPrimaryKey, I imagine I'm not entering proper values for the parameters, but I don't know any proper values for the parameters ... any help? Once again, thanks a lot!
