cakephp Custom validation rule message - cakephp

I have a custom validation rule to check if two passwords entered are the same, and if they arent I wish to have a message that says "Passwords do not match".
The rule works, however, when the passwords don't match it simply displays the normal error message, what's going on?
var $validate=array(
'passwd2' => array('rule' => 'alphanumeric',
'rule' => 'confirmPassword',
'required' => true,
'allowEmpty'=>false));
function confirmPassword($data)
{
$valid = false;
if ( Security::hash(Configure::read('Security.salt') .$data['passwd2']) == $this->data['User']['passwd'])
{
$valid = true;
$this->invalidate('passwd2', 'Passwords do not match');
}
return $valid;
}
It says "This field cannot be left blank"
EDIT:
The strange thing is, if I leave one of the password fields blank, both error messages say "This field cannot be left blank"
However, if I put something in both, then it correctly says "Passwords do not match"

I think you made it too complex. Here is how I do it:
// In the model
public $validate = array(
'password' => array(
'minLength' => array(
'rule' => array('minLength', '8')
),
'notEmpty' => array(
'rule' => 'notEmpty',
'required' => true
)
),
'confirm_password' => array(
'minLength' => array(
'rule' => array('minLength', '8'),
'required' => true
),
'notEmpty' => array(
'rule' => 'notEmpty'
),
'comparePasswords' => array(
'rule' => 'comparePasswords' // Protected function below
),
)
);
protected function comparePasswords($field = null){
return (Security::hash($field['confirm_password'], null, true) === $this->data['User']['password']);
}
// In the view
echo $form->input('confirm_password', array(
'label' => __('Password', true),
'type' => 'password',
'error' => array(
'comparePasswords' => __('Typed passwords did not match.', true),
'minLength' => __('The password should be at least 8 characters long.', true),
'notEmpty' => __('The password must not be empty.', true)
)
));
echo $form->input('password', array(
'label' => __('Repeat Password', true)
));

You should use the 'message' key in your $validate array to specify the message:
'message' => 'Your passwords do not match'
Further reading: http://book.cakephp.org/view/1143/Data-Validation

And then you can access the fields and the messages by $this->modelName->invalidFields(), which will return you the fields that didn't pass the validation and the message that you have setted for them...
In the controller I mean...

Cakephp isUnique is not working properly

isUnique validation doesn't work if there there is validation error only of uniqueness in user creating form and gives error of 'The page isn't redirecting properly'.
Model code is:
class User extends AppModel {
public $validate = array(
'username' => array(
'notEmpty' => array(
'rule' => array('email'),
'message' => 'Please supply a valid email address.'
),
'isUnique' => array(
'rule' => 'isUnique',
'message' => 'This email has already been taken.'
)
),
'password' => array(
'min' => array(
'rule' => array('minLength', 3),
'message' => 'Password must be at least 3 characters.'
),
'required' => array(
'rule' => 'notEmpty',
'message' => 'Please enter a password.'
),
),
'cpassword' => array(
'required' => 'notEmpty',
'match' => array(
'rule' => 'validatePasswdConfirm',
'message' => 'Passwords do not match'
)
)
);
}
When I enter mismatch passwords then it gives error of 'Passwords do not match' and also gives error 'This email has already been taken.' if a username is already there in users table but the problem is when I Only enter the username which already exists and enter a match password then it goes to a page with error "The page isn't redirecting properly".
How can I fix this issue?
Thanks in advance.
if you have used $this->Auth->login() in beforeFilter for any condition, remove it and use !empty($this->Auth->user('id')) instead of $this->Auth->login() for you conditions in beforeFilter.

isUnique Validation in CakePHP hasMany association

Database Structure
I have two tables, users and nicks.
In users table I have a field username and in nicks table I have a field nick_name
There is a hasMany association between users and nicks
public $hasMany = array(
'Nick' => array(
'className' => 'Nick',
'foreignKey' => 'user_id',
'dependent' => true
)
);
In the User model I am validating to allow only unique username during registration by
'username must be unique' => array(
'rule' => 'isUnique',
'message' => 'username is already taken'
)
but I also don't want to allow users to register any previously used nick names as their username. for that.
'somebody use that name as a nickname' => array(
'rule' => 'checkNickName',
'message' => 'That name is already in use'
)
and
public function checkNickName(){
$nick2 = $this->find('all');
$nickNames = array();
foreach($nick2 as $name2){
foreach($name2['Nick'] as $name1){
array_push($nickNames,strtolower($name1['nick_name']));
}
}
$username = strtolower($this->data['User']['username']);
return in_array($username,$nickNames);
}
But that's not working. What should I to make it work?
If I understand correctly, you want to ensure the username is unique but also that the username has not been used as a nickname by anybody also, so why not use something like this?
public function checkNickIsUnique($check = array()) {
$value = array_values($check);
$nicknameExists = $this->Nick->find('count', array(
'conditions' => array(
'Nick.nick_name' => $value[0]
)
));
return ($nicknameExists > 0) ? false : true;
}
And in your user model, assuming it's directly related to nick, have this in the validation.
public $validate = array(
'username' => array(
'isUnique' => array(
'rule' => 'isUnique',
'message' => 'That username has already been taken'
),
'checkNickIsUnique' => array(
'rule' => array('checkNickIsUnique'),
'message' => 'Your username has already been taken as a nickname'
)
),
);
All it's doing is passing the value from the validation to the method, and checking if that value exists as a nickname within the nicks table, if it does it fails validation otherwise it passes.
First find the nicknames.
$nick2 = $this->Nick->find('all');
Then the result array will be
nick2 = array(
0 => array( //first foreach
'Nick' => array(
nickname => 'TEST'
)
)
)
so remove the second foreach and save the value as using $name2['Nick']['nickname']
public function checkNickName(){
$nick2 = $this->Nick->find('all');
$nickNames = array();
foreach($nick2 as $name2){
array_push($nickNames,strtolower($name2['Nick']['nick_name']));
}
$username = strtolower($this->data['User']['username']);
return in_array($username,$nickNames);
}
just need use the username of the input form.
in your view example:
<?php echo $this->Form->input('username', array(
'label' => array(
'text' => 'Provide your username'
)
)); ?>
and in your model you need change
'username' => array(
'nonEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'not empty please',
'allowEmpty' => false
),
'unique' => array(
'rule' => array('isUniqueUsername'),
'message' => 'username is already taken'
),
),
'nickname' => array(
'nonEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'not empty',
'allowEmpty' => false
),
'unique' => array(
'rule' => array('checkNickName'),
'message' => 'That name is already in use'
)
)
your condition example for is validation is unique user name, use this:
EDIT
'username' => array(
'unique' => array(
'rule' => array('checkNickName'),
'message' => 'username is already taken'
),
),
in your function:
public function checkNickName($check) {
$this->loadModel('Nick');
$username = $this->Nick->find(
'first',
array(
'fields' => array(
'Nick.id',
'Nick.nickname'
),
'conditions' => array(
'Nick.nickname' => $check['username']
)
)
);
if(!empty($username)){
if($this->data[$this->alias]['id'] == $username['User']['id']){
return true;
}else{
return false;
}
}else{
return true;
}
}
A better solution that doesn't require tons of additional code is this:
$valid = $this->User->saveAll($this->request->data, array(
'atomic' => false,
'validate' => 'only'
));
debug($valid);
It will validate the record and all other records attached to it as well, no more code required, just make sure you have the isUnique rule in your associated nicknames model. It will as well invalidate the correct fields in your form.

Controller validation in Cakephp

I wish to validate in controller in cakephp. Though my validations are working well in Models but instead of model I wish to validate it in controller as well.
What I did to validate in contrller.
$validates = array('email' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A email is required'
),
'isUnique' => array(
'rule' => array('notEmpty'),
'message' => 'This email is already registered'
),
'email' => array(
'rule' => array('email'),
'message' => 'Enter valid mail address'
)
));
if ($this->User->validates($validates)) {
die("Action can be performed as validated !! Fields are correct");
} else {
die("Action can't be performed !! Fields are in-correct");
}
It always end me in correct condition no matters if field is correct or not. Please help
Setting $this->Model->validates = $validates; will work for you as suggested in the previous answer but you risk overwriting all other validation rules which may be set in the Model. It's much better to add, modify and remove validation rules on the fly like such:
$this->Model->validator()
->add('email', 'required', array(
'rule' => array('notEmpty'),
'message' => 'A email is required'
))
->add('email', 'isUnique', array(
'rule' => array('notEmpty'),
'message' => 'This email is already registered'
))
->add('email', 'email', array(
'rule' => array('email'),
'message' => 'Enter valid mail address'
));
I left your array exactly as you presented it, however I assume you have the wrong rule on isUnique
You can read more about binding rules here: http://book.cakephp.org/2.0/en/models/data-validation.html#dynamically-change-validation-rules
Try this -
$data = $this->request->data;
$this->ModelName->set($data);
if ($this->ModelName->validates()) {
// it validated logic
} else {
// didn't validate logic
$errors = $this->ModelName->validationErrors;
}
Suppose you want to validate a particular field in cakephp Controller, then for that below code will be use -
$this->ModelName->validationErrors['html_field_name'][] = 'Your Error Message goes here';
Edit your code:
$this->$Model->validate = array('email' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A email is required'
),
'isUnique' => array(
'rule' => array('notEmpty'),
'message' => 'This email is already registered'
),
'email' => array(
'rule' => array('email'),
'message' => 'Enter valid mail address'
)
));
It work with me :)

Auth not validating properly on saving passwords

This seemed to be working perfectly, I added a checkbox to my form so the user can decide whether to change the password or not. In the add user action the validation works fine and won't save the user if there are any errors, but with my edit user action it will still save them when both password fields are blank, but still validate them properly if there's any data in either password input. Here's my model:
class User extends AppModel {
var $name = 'User';
var $displayField = 'name';
var $validate = array(
'username' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'User must have a username to login with',
),
),
'password' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'User must have a password',
),
'alphanumeric' => array(
'rule' => array('alphanumeric'),
'required' => true,
'message' => 'User must have a password'
),
'minlength' => array(
'rule' => array('minlength', 6),
'message' => 'Password must be at least 6 characters',
),
'confirmPassword' => array(
'rule' => array('confirmPassword', 'password'),
'message' => 'Passwords do not match'
),
),
'password_confirm' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'User must have a password',
),
'alphanumeric' => array(
'rule' => array('alphanumeric'),
'required' => true,
'message' => 'User must have a password'
),
'minlength' => array(
'rule' => array('minlength', 6),
'message' => 'Password must be at least 6 characters',
),
),
);
function confirmPassword($data) {
return ($data['password'] === Security::hash(Configure::read('Security.salt').$this->data['User']['password_confirm']));
}
And here's my edit user action:
function admin_edit($id = null) {
$this->set('title_for_layout', 'Users / Editing User');
if (!$id && empty($this->data)) {
$this->Session->setFlash(__('Invalid user specified', true), 'flash_error');
$this->redirect(array('action' => 'index'));
}
if (!empty($this->data)) {
$redirect = array('action' => 'index');
if ($this->data['User']['edit_password'] == 1) {
$fields = array('username', 'confirm_password', 'password', 'name');
if ($this->data['User']['id'] == $this->Auth->user('id')) {
$redirect['action'] = 'logout';
}
} else {
$fields = array('username', 'name');
}
if ($this->User->save($this->data, true, $fields)) {
$this->Session->setFlash(__(sprintf('The user <i>%s</i> was saved successfully.', $this->data['User']['username']), true), 'flash_success');
$this->redirect($redirect);
} else {
$this->Session->setFlash(__('There were errors when trying to save the user', true), 'flash_error');
}
}
if (empty($this->data)) {
$this->data = $this->User->read(null, $id);
$this->data['User']['password'] = '';
$this->data['User']['edit_password'] = 0;
}
}
Sorry in advance as this is only a half-answer, but should get you moving in the right direction.
The Auth component will automatically hash the password field if the username field is also present in the submitted data
So you have set up your data to either anticipate this.. or avoid it.
This method will come in handy too.

Cakephp - checkPasswords is always false

I'm working on the signup process and want to check if the two passwords (password + re-entered password) are equal. These are my validation rules in the User Model:
var $validate = array(
'username' => array(
'notEmpty' => array(
'rule' => array('minLength', 5),
'required' => true,
'allowEmpty' => false,
'message' => 'User name has to be at least 5 characters long'
),
array(
'rule' => 'isUnique',
'message' => 'User name taken. Use another'
)
),
'password' => array(
'notEmpty' => array(
'rule' => array('minLength', 6),
'required' => true,
'allowEmpty' => false,
'message' => 'Password has to be at least 6 characters long'
),
'password_similar' => array(
'rule' => 'checkPasswords',
'message' => 'Entered passwords does not match'
)
),
'email' => array(
'rule' => 'email',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a valid email'
)
);
In the users_controller.php I have the checkPasswords function:
function checkPasswords($data) {
if($data['password'] == $this->data['User']['password2hashed'])
return true;
else
return false;
}
An my singup function looks like this:
function signup(){
if (!empty($this->data)) {
if(isset($this->data['User']['password2']))
$this->data['User']['password2hashed'] = $this->Auth->password($this->data['User']['password2']);
$this->User->create();
if ($this->User->save($this->data)) {
.
.
.
}
No matter what I do, the passwords do not match. Even if I change the checkPasswords function to this:
function checkPasswords($data) {
return true;
}
What could cause this behavior?
OMG I just realised that the checkPasswords Function is not supposed to be in the controller but in the model. Problem solved, I'm ashamed...
