ZF2 form validation not working properly for email - regex

Question

i have a input box with type="email" and validation it with zend validator
<input type="email" name="email" > email </input>
'email' => array(
'required' => true,
'validators' => array(
array(
'name' => 'Regex',
'options' => array(
'pattern'=>'/^[a-zA-Z0-9.!#$%&\'*+\/=?^_`{|}~-]+#[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/',
'messages' => array(
\Zend\Validator\Regex::NOT_MATCH=>'Please fill correct email ',
)
),
'break_chain_on_failure' => true
),
),
problem is if i use another array to check for
IS_EMPTY
zend regex again does not display the above error instead display default zend regex error and if i remove IS_EMPTY then it works fine. regex error is
1. input does not match to expression '/^[a-zA-Z0-9.!#$%&\'*+\/=?^_`{|}~-]+#[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/'
EXACTLY NOT ABLE TO UNDERSTAND WHY THIS WORKS FINE WITHOUT EMPTY CHECK AND DOESN'T WORK ALONG WITH IT

Answer 1

You don't need to use notEmpty, you only need to set the field as "required" and specify the error message:
$this->add(array(
'name' => 'email',
'required' => true,
'error_message' => 'Please entry e-mail.',
'validators' => array(
array(
'name' => 'EmailAddress',
'options' => array (
'messages' => array(EmailAddress::INVALID => 'Please specify a valid e-mail.'),
),
'break_chain_on_failure' => true,
),
),
));

Answer 2

I have also the same dilemma where this "input does not match to expression" always appears instead of the message for EmailAddress::INVALID_FORMAT. But I found that the code you posted fixed the same error I had. This is my code.
'validators' => array(
array (
'name' => 'Regex',
'options' => array(
'pattern'=>'/^[a-zA-Z0-9.!#$%&\'*+\/=?^_`{|}~-]+#[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/',
'messages' => array(
Regex::NOT_MATCH => 'Please provide a valid email address.',
),
),
'break_chain_on_failure' => true
),
array(
'name' => 'EmailAddress',
'options' => array(
'messages' => array(
EmailAddress::INVALID_FORMAT => 'Please provide a valid email address.',
EmailAddress::DOT_ATOM => '',
EmailAddress::INVALID_FORMAT => '',
EmailAddress::INVALID_LOCAL_PART => '',
EmailAddress::QUOTED_STRING => '',
)
),
),
),
