string [string] form_fields()
- Similiar to form_field(), but returns a map with all the name/value pairs from the relay request being handled. Unlike the form_field() function, this allows iterating over all the fields, and can distinguish a field with a blank value from a nonexistent field. (The exception to this being checkboxes, which return no information when unchecked.)
Used to read form information in User Interface Scripts.
Read the form fields in a UI script for use later.
string [string] fields; fields = form_fields(); boolean success = count(fields) > 0;
