用於登錄失敗的FormElementError

Question

我對Zend Framework 2很新。當我嘗試登錄錯誤憑證時，它不顯示任何錯誤。那麼在這種情況下應該是什麼代碼來顯示FormElementError。 我LoginFilter.php在下面給出：

use Zend\InputFilter\InputFilter; 
class LoginFilter extends InputFilter 
{ 
    public function __construct() 
    { 
$this->add(array(
     'name'  => 'email', 
     'required' => true, 
     'validators' => array(
      array(
       'name' => 'EmailAddress', 
       'options' => array(
        'domain' => true, 
       ), 
      ), 
     ), 
    )); 
    $this->add(array(
     'name'  => 'password', 
     'required' => true, 
     //'validators' => array(), 
    )); 
    } 

} 

Answer 1

所以這是我如何與一個自定義輸入過濾做到這一點。我將setMessage應用到Zend-Validator,這是通過setMessage().被塞進ValidatorChain下面你可以看到$emailDoesNotExist->setMessage('This e-mail address is already in use');在這裏我設置了我的錯誤消息。你也可以像StringLength變量那樣做（$stringLength）。

namespace User\InputFilter; 

use Zend\Db\Adapter\Adapter; 
use Zend\Filter\FilterChain; 
use Zend\Filter\StringTrim; 
use Zend\I18n\Validator\Alnum; 
use Zend\InputFilter\Input; 
use Zend\InputFilter\InputFilter; 
use Zend\Validator\Db\NoRecordExists; 
use Zend\Validator\EmailAddress; 
use Zend\Validator\Identical; 
use Zend\Validator\Regex; 
use Zend\Validator\StringLength; 
use Zend\Validator\ValidatorChain; 

class AddUser extends InputFilter 
{ 
/** 
* 
* @var InputFilter $dbAdapter 
*/ 
protected $dbAdapter; 

public function __construct(Adapter $dbAdapter) 
{ 
    $this->dbAdapter = $dbAdapter; 

    $firstName = new Input('first_name'); 
    $firstName->setRequired(true); 
    $firstName->setValidatorChain($this->getNameValidatorChain()); 
    $firstName->setFilterChain($this->getStringTrimFilterChain()); 

    $lastName = new Input('last_name'); 
    $lastName->setRequired(true); 
    $lastName->setValidatorChain($this->getNameValidatorChain()); 
    $lastName->setFilterChain($this->getStringTrimFilterChain()); 

    $email = new Input('email'); 
    $email->setRequired(true); 
    $email->setValidatorChain($this->getEmailValidatorChain()); 
    $email->setFilterChain($this->getStringTrimFilterChain()); 

    $password = new Input('password'); 
    $password->setRequired(true); 
    $password->setValidatorChain($this->getPasswordValidatorChain()); 
    $password->setFilterChain($this->getStringTrimFilterChain()); 

    $repeatPassword = new Input('repeat_password'); 
    $repeatPassword->setRequired(true); 
    $repeatPassword->setValidatorChain($this->getRepeatPasswordValidatorChain()); 
    $repeatPassword->setFilterChain($this->getStringTrimFilterChain()); 

    $this->add($firstName); 
    $this->add($lastName); 
    $this->add($email); 
    $this->add($password); 
    $this->add($repeatPassword); 
} 


/** 
* Gets the validation chain for the first name and last name inputs 
* 
* @return ValidatorChain 
*/ 
protected function getNameValidatorChain() 
{ 
    $stringLength = new StringLength(); 
    $stringLength->setMin(2); 
    $stringLength->setMax(50); 

    $validatorChain = new ValidatorChain(); 
    $validatorChain->attach(new Alnum(true)); 
    $validatorChain->attach($stringLength); 

    return $validatorChain; 
} 

/** 
* Gets the validation chain for the email input 
* 
* @return ValidatorChain 
*/ 
protected function getEmailValidatorChain() 
{ 
    $stringLength = new StringLength(); 
    $stringLength->setMin(2); 
    $stringLength->setMax(50); 

    $emailDoesNotExist = new NoRecordExists(
     array(
      'table' => 'user', 
      'field' => 'email', 
      'adapter' => $this->dbAdapter 
     ) 
    ); 

    $emailDoesNotExist->setMessage('This e-mail address is already in use'); 

    $validatorChain = new ValidatorChain(); 
    $validatorChain->attach($stringLength, true); 
    $validatorChain->attach(new EmailAddress(), true); 
    $validatorChain->attach($emailDoesNotExist, true); 

    return $validatorChain; 
} 

/** 
* 
* @return ValidatorChain 
*/ 
protected function getPasswordValidatorChain() 
{ 
    $stringLength = new StringLength(); 
    $stringLength->setMax(6); 

    $oneNumber = new Regex('/\d/'); //checking to make sure it has at least one number 
    $oneNumber->setMessage('Must contain at least one number'); 

    $validatorChain = new ValidatorChain(); 
    $validatorChain->attach($stringLength); 
    $validatorChain->attach($oneNumber); 

    return $validatorChain; 
} 

/** 
* 
* @return ValidatorChain 
*/ 
protected function getRepeatPasswordValidatorChain() 
{ 
    $identical = new Identical(); 
    $identical->setToken('password'); // Name of the input whose value to match 
    $identical->setMessage('Passwords must match'); 

    $validatorChain = new ValidatorChain(); 
    $validatorChain->attach($identical); 

    return $validatorChain; 
} 

/** 
* 
* @return \User\InputFilter\FilterChain 
*/ 
protected function getStringTrimFilterChain() 
{ 
    $filterChain = new FilterChain(); 
    $filterChain->attach(new StringTrim()); 

    return $filterChain; 
}
