Re: form vars

Assuming you POST the form variables, then the data will be in the associative array $HTTP_POST_VARS. Here's an example of code I use to simply print out every variable POSTed by a form. This code can also cope with an array from a form. The code shows a way of looping through each variable, which you could adapt to do whatever you need to do. for( reset($HTTP_POST_VARS); $key = key($HTTP_POST_VARS); next($HTTP_POST_VARS) ) { if ( is_array($HTTP_POST_VARS[$key]) ) { $num=count($HTTP_POST_VARS[$key]); for ($i=0; $i<$num; $i++) print "$$key"."[$i] = ". $HTTP_POST_VARS[$key][$i]. "<br>\n"; } else { print "$$key = ". $HTTP_POST_VARS[$key]. "<br>\n"; } } Hope this helps - Nick Nick Talbott IT Policy and Strategy Manager, Powys County Council, UK email nickt@powys.gov.uk FAX +44 (0) 1597 824781 web http://www.powys.gov.uk and http://www.powysweb.co.uk
