The NotEmpty validator

The NotEmpty validates only that the given input has a non empty value. This differs from empty and thus native boolean conversion in PHP.

Predefined errormessage Template formatting parameters:

1. :value - the string representation of the validated $value
2. :type - the datatype of the validated $value
   1. :type = "boolean" - for boolean type
   2. :type = "integer" - for integer type
   3. :type = "float" - for float type
   4. :type = "string" - for string type
   5. :type = "array" - for array type
   6. :type = "object" - for object type
   7. :type = "resource" - for resource type
   8. :type = "resource (closed)" - for closed resource type
   9. :type = "NULL" - for nulls
   10. :type = "unknown type" - for unknown types
3. :strict-type - the strict datatype of the validated $value differs from :type
   1. any object corresponds to the name of the class get_class() results
