I am using following code to add customise default e

Answer 1

The StringLength validator does not check for the input to be empty or not. It checks against lengths. Following message templates exist for StringLength validator:

const INVALID   = 'stringLengthInvalid';
const TOO_SHORT = 'stringLengthTooShort';
const TOO_LONG  = 'stringLengthTooLong';

/**
 * @var array
 */
protected $messageTemplates = array(
    self::INVALID   => "Invalid type given. String expected",
    self::TOO_SHORT => "The input is less than %min% characters long",
    self::TOO_LONG  => "The input is more than %max% characters long",
);

See the example of @Developer for a direct approach. Though i suggest going with the CamelCased naming of the Validators, so 'name' => 'NotEmpty' instead of 'name' => 'not_empty'

You can check which messageTemplates exist if you see the code for each of the validator classes. You will find them under ./vendor/zendframework/zendframework/library/Zend/Validator/*
