我创建了一个表单来将用户添加到数据库并使用户可以登录.
I have created a form to add a user to a database and make user available for login.
现在我有两个密码字段(第二个用于验证第一个).如何向 zend_form 添加用于此类验证的验证器?
Now I have two password fields (the second is for validation of the first). How can I add a validator for this kind of validation to zend_form?
这是我的两个密码字段的代码:
This is my code for the two password fields:
$password = new Zend_Form_Element_Password('password', array(
'validators'=> array(
'Alnum',
array('StringLength', array(6,20))
),
'filters' => array('StringTrim'),
'label' => 'Wachtwoord:'
));
$password->addFilter(new Ivo_Filters_Sha1Filter());
$password2 = new Zend_Form_Element_Password('password', array(
'validators'=> array(
'Alnum',
array('StringLength', array(6,20))
),
'filters' => array('StringTrim'),
'required' => true,
'label' => 'Wachtwoord:'
));
$password2->addFilter(new Ivo_Filters_Sha1Filter());
当我在寻找相同的东西时,我发现这个非常有效的通用 Validator for Identical Fields.我现在找不到它所以我只是发布代码...
When I was looking for the same, I found this very well working generic Validator for Identical Fields. I don't find it now so I just post the code...
<?php
class Zend_Validate_IdenticalField extends Zend_Validate_Abstract {
const NOT_MATCH = 'notMatch';
const MISSING_FIELD_NAME = 'missingFieldName';
const INVALID_FIELD_NAME = 'invalidFieldName';
/**
* @var array
*/
protected $_messageTemplates = array(
self::MISSING_FIELD_NAME =>
'DEVELOPMENT ERROR: Field name to match against was not provided.',
self::INVALID_FIELD_NAME =>
'DEVELOPMENT ERROR: The field "%fieldName%" was not provided to match against.',
self::NOT_MATCH =>
'Does not match %fieldTitle%.'
);
/**
* @var array
*/
protected $_messageVariables = array(
'fieldName' => '_fieldName',
'fieldTitle' => '_fieldTitle'
);
/**
* Name of the field as it appear in the $context array.
*
* @var string
*/
protected $_fieldName;
/**
* Title of the field to display in an error message.
*
* If evaluates to false then will be set to $this->_fieldName.
*
* @var string
*/
protected $_fieldTitle;
/**
* Sets validator options
*
* @param string $fieldName
* @param string $fieldTitle
* @return void
*/
public function __construct($fieldName, $fieldTitle = null) {
$this->setFieldName($fieldName);
$this->setFieldTitle($fieldTitle);
}
/**
* Returns the field name.
*
* @return string
*/
public function getFieldName() {
return $this->_fieldName;
}
/**
* Sets the field name.
*
* @param string $fieldName
* @return Zend_Validate_IdenticalField Provides a fluent interface
*/
public function setFieldName($fieldName) {
$this->_fieldName = $fieldName;
return $this;
}
/**
* Returns the field title.
*
* @return integer
*/
public function getFieldTitle() {
return $this->_fieldTitle;
}
/**
* Sets the field title.
*
* @param string:null $fieldTitle
* @return Zend_Validate_IdenticalField Provides a fluent interface
*/
public function setFieldTitle($fieldTitle = null) {
$this->_fieldTitle = $fieldTitle ? $fieldTitle : $this->_fieldName;
return $this;
}
/**
* Defined by Zend_Validate_Interface
*
* Returns true if and only if a field name has been set, the field name is available in the
* context, and the value of that field name matches the provided value.
*
* @param string $value
*
* @return boolean
*/
public function isValid($value, $context = null) {
$this->_setValue($value);
$field = $this->getFieldName();
if (empty($field)) {
$this->_error(self::MISSING_FIELD_NAME);
return false;
} elseif (!isset($context[$field])) {
$this->_error(self::INVALID_FIELD_NAME);
return false;
} elseif (is_array($context)) {
if ($value == $context[$field]) {
return true;
}
} elseif (is_string($context) && ($value == $context)) {
return true;
}
$this->_error(self::NOT_MATCH);
return false;
}
}
