Ok,
To summarise your requirements:
1. No javascript validation (users must reload for any validation).
2. No information on which field is missing.
3. Same message on all forms in all cases.
4. Simplest possible syntax for html designers who set the required fields.
Possible syntaxes:
a) Set hidden required field on form
e.g. <INPUT TYPE="HIDDEN" NAME="REQUIRED" VALUE="name,address,phone">
b) Set variable in php e.g.
$required = 'name address phone';
$required = 'name,address,phone';
$required = array($name,$address,$phone);
c) Call function in php e.g.
required('name address phone');
required('name,address,phone');
required($name,$address,$phone);
$required = 'a b';
$required = 'a,b';
$required = array($a,$b);
$required = a b ;
//required(a b);
required(a,b);
ho handles the Javascript on-page validation? Or do you always force your users to
wait for a page
reload before telling them about simple errors? The Javascript is
