var $validate = array(
'password' => array(
'passwordlength' => array('rule' => array('between', 8, 50),'message' => 'Enter 8-50 chars'),
'passwordequal' => array('checkpasswords','message' => 'Passwords dont match')
)
);
function checkpasswords()
{
return strcmp($this->data['Airline']['password'],$this->data['Airline']['confirm password']);
}
这段代码无法正常工作，并且始终会显示错误消息，即使它们匹配。此外，当我进行编辑时，会出现以下错误，因为没有密码字段。有什么解决方法吗？
Undefined index: password [APP/models/airline.php, line 25]
你是否正在使用 AuthComponent？请注意它会对所有传入的密码字段进行哈希处理（但不包括“确认密码”字段，请通过debug($this->data)检查），因此这些字段将永远不相同。请阅读手册并使用AuthComponent::password进行检查。
话虽如此，以下是我使用的一些内容：
public $validate = array(
'password' => array(
'confirm' => array(
'rule' => array('password', 'password_control', 'confirm'),
'message' => 'Repeat password',
'last' => true
),
'length' => array(
'rule' => array('password', 'password_control', 'length'),
'message' => 'At least 6 characters'
)
),
'password_control' => array(
'notempty' => array(
'rule' => array('notEmpty'),
'allowEmpty' => false,
'message' => 'Repeat password'
)
)
);
public function password($data, $controlField, $test) {
if (!isset($this->data[$this->alias][$controlField])) {
trigger_error('Password control field not set.');
return false;
}
$field = key($data);
$password = current($data);
$controlPassword = $this->data[$this->alias][$controlField];
switch ($test) {
case 'confirm' :
if ($password !== Security::hash($controlPassword, null, true)) {
$this->invalidate($controlField, 'Repeat password');
return false;
}
return true;
case 'length' :
return strlen($controlPassword) >= 6;
default :
trigger_error("Unknown password test '$test'.");
}
}
以下是此方法不好的原因：
password_control的字段。如果您的数据中没有该字段，则需要使用字段白名单或禁用验证，例如：$this->User->save($this->data, true, array('field1', 'field2'))。尽管如此，该方法仍然能够透明地验证并生成正确的错误消息，而无需在控制器中添加任何额外的代码。
这里有错误
'passwordequal' => array('checkpasswords','message' => 'Passwords dont match')
'passwordequal' => array('rule' =>'checkpasswords','message' => 'Passwords dont match')
另外，strcmp函数在以上代码中也存在错误，因为它总是返回0（即False）。
if(strcmp($this->data['Airline']['password'],$this->data['Airline']['confirm_password']) ==0 )
{
return true;
}
return false;
return strcmp(...) == 0。 - deceze验证密码时，需要输入旧密码和确认密码。
class Adminpassword extends AppModel
{
public $name = 'Admin';
public $primaryKey = 'id';
public $validate = array(
'oldpassword' => array(
array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Please Enter Current password'
),
array(
'rule' =>'checkcurrentpasswords',
'message' => 'Current Password does not match'
)
),
'password' => array(
array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Please Enter password'
),
array(
'rule' => array('minLength', 6),
'message' => 'Passwords must be at least 6 characters long.',
)
),
'cpassword' => array(
array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Please Enter Confirm password'
),
array(
'rule' => 'checkpasswords',
'required' => true,
'message' => 'Password & Confirm Password must be match.'
)
)
);
function checkpasswords() // to check pasword and confirm password
{
if(strcmp($this->data['Adminpassword']['password'],$this->data['Adminpassword']['cpassword']) == 0 )
{
return true;
}
return false;
}
function checkcurrentpasswords() // to check current password
{
$this->id = $this->data['Adminpassword']['id'];
$user_data = $this->field('password');
//print_r(Security::hash($this->data['Adminpassword']['oldpassword'], 'sha1', true));
if ($user_data == (Security::hash($this->data['Adminpassword']['oldpassword'], 'sha1', true)))
{
return true;
}
else
{
return false;
}
}
}
对于使用身份验证的CakePHP 2.x用户，您可能会注意到“AuthComponent不再自动哈希它可以找到的每个密码。”也就是说，上面的解决方案可能不是解决2.x问题的正确方法。 http://book.cakephp.org/2.0/en/core-libraries/components/authentication.html#hashing-passwords
public function match($check, $with) {
// Getting the keys of the parent field
foreach ($check as $k => $v) {
$$k = $v;
}
// Removing blank fields
$check = trim($$k);
$with = trim($this->data[$this->name][$with]);
// If both arent empty we compare and return true or false
if (!empty($check) && !empty($with)) {
return $check == $with;
}
// Return false, some fields is empty
return false;
}
而且$validate方法必须像这样：
public $validate = array(
'password' => array(
'match' => array(
'rule' => array('match', 'password2'),
'message' => 'Passwords doesnt match',
),
),
);
其中password2是要与您的第一个password字段进行比较的字段
我很高兴分享它！:D
$this->datadata是否是你想要的？如果不是，那就是问题所在了。 - Stephenstrcmp返回0。但0将被理解为false，因此它会做与您预期的完全相反的事情。 - deceze
