To answer your question:
$postfld = $HTTP_POST_VARS[$fname[$i]];
should work. BTW, I just use something like:
if ($client) { // or in your case: if (${$fname[$i]})
// code to be evaluated if $client exists and is not 0, not null/void/nil, and is
not an empty string
}

Specifically,
If I have 3 HTTP_POST_VARS:
HTTP_POST_VARS[client] = test1
HTTP_POST_VARS[directory]= test2
HTTP_POST_VARS[password] =
and I don't know the names of the vars ahead of time, how would I run a
check to see if they exist and then get the specific POST_VARS's value. This
is what I've got so far:
$squery = select * from $db where ;
$qh = fw_query(select * from $db);
$fields = odbc_num_fields($qh);
for ($i=1;$i=$fields;$i++) {
# assign $fname the possible field names in the database
(client,directory,password)
$fname[$i] = odbc_field_name($qh,$i);
# assign $postfld the variable name, ie. $HTTP_POST_VARS[client]
$postfld = $HTTP_POST_VARS[($fname[$i])];
# check that it exists and is not blank
if (isset($postfld) AND ($postfld != )) {
$value[$i] = $postfld;
$squery.= $fname[$i] like $value[$i] AND ;
}
}
# pop last AND
$squery= substr($squery, 0,-5);
so how do you make this work: $postfld = $HTTP_POST_VARS[($fname[$i])];
thanks,
