Just thought I would share this for anyone who is interested... Basically I had a group of inputs (in this case, the street, city, state, and zip of an address) that I wanted to treat as one requirement, i.e., test at one time if any of the fields in the group are missing and then output a single error message. Instructions are in the comments.

// ----- PURPOSE -----
// This makes a group of form fields required
// as a group and outputs a single error message.
// ----- SETUP -----
// 1) Don't forget to add the following attribute
// to the FormIt snippet call:
// —————————————————————————————————
// &customValidators=`groupRequired`
// —————————————————————————————————
//
// 2) Name all your group fields with one prefix:
// —————————————————————————————————————————
// <input name="myGroup_field1" val="" />
// <input name="myGroup_field2" val="" />
// <input name="myGroup_field3" val="" />
// —————————————————————————————————————————
//
// 3) Call the validator in the FormIt snippet call
// using just the prefix (be sure to include a leading "|"
// if leaving the error message blank):
// —————————————————————————————————————————————————————————————————————————————————————————
// &validate=`myGroup:groupRequired=`Optional error message|_field1|_field2|_field3|...`
// —————————————————————————————————————————————————————————————————————————————————————————
//
// 4) Place the error placeholder inline on just the prefix
// —————————————————————————
// [[!+fi.error.myGroup]]
// —————————————————————————
// parse parameters
$param = explode('|',$param);
// set the error message
$errorMssg = !empty($param[0]) ? $param[0] : 'These fields are required';
// test fields
for ($i=1; $i<count($param); $i++) {
// test if field is an array or not (work with options and other field types)
if ( is_array($validator->fields[$key.$param[$i]]) ) {
$field = $validator->fields[$key.$param[$i]][0];
} else {
$field = $validator->fields[$key.$param[$i]];
}
// bounce if any field is empty
if (empty($field)) {
$validator->addError($key,$errorMssg);
return true;
}
}
return true;
