I wanna validate multiple fields at one place. So in a form I have included 4 fields
as follows
facebook_link
twitter_link
google_plus_link
linked_in_link
The user atleast type any one field of above. Please help me to get the solution like, the user types anyone of the links in the form.
you may add your own Validation Methods.
public $validate = array(
'facebook_link' => array(
'rule' => array('validateLink'),
'message' => '...'
),
'twitter_link' => array(
'rule' => array('validateLink'),
'message' => '...'
),
'google_plus_link' => array(
'rule' => array('validateLink'),
'message' => '...'
),
'linked_in_link' => array(
'rule' => array('validateLink'),
'message' => '...'
),
);
public function validateLink($link) {
$allFieldsAreEmpty = (
empty($this->data[$this->alias]['facebook_link']) &&
empty($this->data[$this->alias]['twitter_link']) &&
empty($this->data[$this->alias]['google_plus_link']) &&
empty($this->data[$this->alias]['linked_in_link'])
);
return !$allFieldsAreEmpty;
}
Hope this will work for you.
public $validate = array(
'facebook_link' => array(
'rule' => array('customValidation','facebook_link'),
'message' => 'Please enter facebook link.'
),
'twitter_link' => array(
'rule' => array('customValidation','twitter_link'),
'message' => 'Please enter twitter link.'
),
'google_plus_link' => array(
'rule' => array('customValidation'),
'message' => 'Please enter google plus link.'
),
'linked_in_link' => array(
'rule' => array('customValidation'),
'message' => 'Please enter linkedin link.'
),
);
function customValidation($data , $filed) {
if(empty($data[$filed])) {
return false;
}
return true;
}

I am loading a model in different controller.
Controller name in which I am loading different model is - "MembersController" and I am loading "Usermgmt" Model of "UsermgmtController".
"Usermgmt" Model has validation as following-
public $validate = array(
'email' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for email.'
),
'duplicate' => array(
'rule' => 'isUnique',
'on' => 'create',
'message' => 'This email is already exist.'
),
'duplicate1' => array(
'rule' => 'email',
'message' => 'Please enter valid email.'
)
),
'firstname' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for first name.'
)
),
'username' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for user name.'
),
'duplicate' => array(
'rule' => 'isUnique',
'on' => 'create',
'message' => 'This user is already exist.'
)
),
'password' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for password.'
)
),
'confirm_password' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for confirm password.'
),
'duplicate2' => array(
'rule' => 'matchpassword',
'on' => 'create',
'message' => 'Password must be same.'
)
)
);
And now I am applying and loading model in following way.
$this->loadModel('Usermgmt');
$this->Usermgmt->set($this->data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}
But validation are not working and it is inserting empty values.
try uses to load model
Example :
public $uses = array('Usermgmt');
You are using two different instances of $data. namely $this->data and $data
You should be validating the same set of data you want to save, like either of the two following examples, whichever holds your data.
$this->loadModel('Usermgmt');
$this->Usermgmt->set($data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}
Or
$this->loadModel('Usermgmt');
$this->Usermgmt->set($this->data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($this->data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}
Unless you are requiring to do some other logic after validation and before saving you could do away with explicitly calling validates() and just save the data as save() will automatically validate the data for you. Also, I've noticed you are using $this->data, it looks like you are using CakePHP 2 in which case you need to use $this->request->data instead:-
$this->loadModel('Usermgmt');
if ($this->Usermgmt->save($this->request->data) !== false) {
$this->Session->setFlash('User has been added', 'success');
}
If this still fails then make sure you are not overriding beforeValidate() in your model in a way that would cause validation to break.
Folks,
I'm trying to ensure at least one of two fields (last_name or email) is being populated. Each field also has multiple rules. I'm using CakePHP version 2.4.2.
The problem I have at the moment, after multiple permutations of updating and/or moving around the use 'last', 'allowEmpty', 'required', etc, is that the fields just aren't validating at all, or aren't executing all the rules when a field is populated.
Any advice on how to modify the code below to achieve the following behaviour is much appreciated:
1. One of the two fields must be populated;
2. The other rules attached to each field must validate as well (i.e. if a last name is passed, then it must be between 2 and 45 chars and alphanumeric only)
Here's the model code:
public $validate = array(
'last_name'=> array(
'needOne' => array (
'required' => FALSE,
'allowEmpty' => TRUE,
'last' => TRUE,
'rule' => array('checkOne','last_name'),
'message' => 'You must enter at least a contact name or email address.'
),
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'message' => 'Alphabets and numbers only'
),
'between' => array(
'rule' => array('between', 2, 45),
'message' => 'Between 2 to 45 characters'
)
),
'email' => array(
'needOne' => array (
'required' => FALSE,
'allowEmpty' => TRUE,
'last' => TRUE,
'rule' => array('checkOne','email'),
'message' => 'You must enter at least a contact name or email address.'
),
'emailAddress' => array (
'last' => TRUE,
'rule' => array('email', FALSE),
'message' => 'A valid Email address is required'
)
)
);
// Ensure at least the last name or email field value is provided
function checkOne($field) {
if(!empty($this->data[$this->User]['last_name']) ||
!empty($this->data[$this->User]['email'])){
return true;
} else {
return false;
}
}
Thanks in advance!
Thanks very much vicocamacho. I kept at it and, in addition to your advice, found the solution also lay in adding a 'required' => false in the view.
Here's the working solution for any one else with this problem:
The model:
public $validate = array(
'last_name'=> array(
'needOne' => array (
'rule' => 'checkOne',
'message' => 'You must enter at least a contact name or email address.'
),
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'message' => 'Alphabets and numbers only',
'allowEmpty' => TRUE
),
'between' => array(
'rule' => array('between', 2, 45),
'message' => 'Between 2 to 45 characters',
'allowEmpty' => TRUE
)
),
'email' => array(
'needOne' => array (
'rule' => 'checkOne',
'message' => 'You must enter at least a contact name or email address.'
),
'emailAddress' => array (
'rule' => 'email',
'message' => 'A valid Email address is required',
'allowEmpty' => TRUE
)
)
);
// Ensure at least the last name or email field value is provided
public function checkOne($data) {
if(!empty($this->data[$this->alias]['last_name'])
|| !empty($this->data[$this->alias]['email'])) {
return TRUE;
} else {
return FALSE;
}
}
The view/fields (I'm using Bootstrap):
echo $this->Form->input('last_name', array(
'required' => false,
'fieldset' => false,
'label' => false,
'before' => '<label class="control-label">Last Name <span class="one-required">*</span></label>',
'class' => 'form-control',
'placeholder' => 'Last Name',
'div' => 'form-group col-sm-12',
'error' => array(
'attributes' => array(
'wrap' => 'div',
'class' => 'alert alert-danger'
)
)
)
);
echo $this->Form->input('email', array(
'required' => false,
'fieldset' => false,
'label' => false,
'before' => '<label class="control-label">Email <span class="one-required">*</span></label>',
'after' => '',
'class' => 'form-control',
'div' => 'form-group col-sm-12 col-xs-12',
'error' => array(
'attributes' => array(
'wrap' => 'div',
'class' => 'alert alert-danger'
)
)
)
);
Thanks.
Write a custom rule that will check if one of both fields is not empty and use that rule on both fields. And set allowEmpty to true for the other rules.
You should allowEmpty in all the rules that do not check if the fields are present, i updated your code so you can see what i mean, also you need to change the $this->User index in your checkOne to $this->alias otherwise it will always return false:
public $validate = array(
'last_name'=> array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'message' => 'Alphabets and numbers only',
'allowEmpty' => true
),
'between' => array(
'rule' => array('between', 2, 45),
'message' => 'Between 2 to 45 characters',
'allowEmpty' => true
)
),
'email' => array(
'needOne' => array (
'rule' => 'checkOne',
'message' => 'You must enter at least a contact name or email address.'
),
'emailAddress' => array (
'allowEmpty' => true,
'rule' => 'email',
'message' => 'A valid Email address is required'
)
)
);
// Ensure at least the last name or email field value is provided
function checkOne($field) {
if(
!empty($this->data[$this->alias]['last_name']) ||
!empty($this->data[$this->alias]['email'])
)
{
return true;
} else {
return false;
}
}
Okay, so, in short, I'm trying to validate a form, as I've done a million times before with no trouble. However, I'm finding that on logging the validation errors, all the invalidated fields have an index in the validationErrors array but the messages are empty.
Yes, I've definitely set the validation messages in the model so I'm unsure why it's empty.
Here are my model validations:
public $validate = array(
'effective_policy_date' => array(
'date' => array(
'rule' => array('date'),
'message' => 'Invalid date format',
),
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Policy date required',
),
),
'business_address' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Business address required',
),
),
'city' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'City required',
),
),
'zip_code' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Zip code required',
),
),
'state_id' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'State required',
),
),
'contact_person' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Contact person required',
),
),
'phone' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Phone number required',
),
),
'email' => array(
'notEmpty' => array(
'rule' => array('notEmpty'),
'message' => 'Email address required',
),
'email' => array(
'rule' => array('email'),
'message' => 'Invalid email format',
),
),
);
Here's the output of the validationErrors array after submitting the form with empty fields:
[AccountsRequest] => Array
(
[effective_policy_date] => Array
(
)
[policy_number_one] => Array
(
)
[policy_number_two] => Array
(
)
[policy_number_three] => Array
(
)
[policy_number_four] => Array
(
)
[business_address] => Array
(
)
[city] => Array
(
)
[zip_code] => Array
(
)
[state_id] => Array
(
)
)
For completeness sake, here's my Form->create array I use in the view and the controller action responsible for handling the form submission:
Form create() method
<?php
echo $this->Form->create(
'Request',
array(
'novalidate' => 'novalidate',
'action' => 'new_request',
'inputDefaults' => array(
'label' => false,
'div' => false,
'error' => array(
'attributes' => array(
'wrap' => 'label', 'class' => 'error'
)
)
)
)
);
?>
Controller action
public function new_request()
{
$this->page_id = 'requester_newform';
if($this->request->is('post'))
{
if($this->Request->saveAll($this->request->data, array('deep' => true, 'validate' => 'only')))
{
$this->Session->setFlash('Request saved successfully', 'flash/success');
}
else
{
$this->Session->setFlash('Could not save request. Please correct validation errors', 'flash/error');
}
}
}
You'll see some indeces in the validation array that aren't in the validationErrors, that's simply because I haven't quite finished converting the raw HTML to CakePHP forms.
Problem: The validationErrors array shouldn't be empty. It should contain the messages for the notEmpty rules and as a result there are empty error validation elements on the Form's frontend. Any ideas about what I'm doing wrong?
Aarg, how annoying. I've figured it out and it's a lesson well learnt.
For anyone having a similar issue in the future, make sure that your input fields conform to the relationships of the current form's Model.
For instance, in this example, my form's model is 'Request'. Request hasMany 'AccountsRequest'. So my form inputs were something like:
AccountsRequest.effective_policy_date
where it should have been
AccountsRequest.0.effective_policy_date
With this change, my model validation messages are now showing without issue.
I'd still love to know, however, why CakePHP even picked up those fields as invalid and further, if it was intelligent enough to pick up those fields as invalid why it didn't give me validation messages.
Oh well.....
I just downloaded a fresh copy of cakephp version 2.3.0 and I am trying to validate a select field of a form that I have just created:
echo $this->Form->input('province_id', array('empty' => '- select -', 'options' => $options));
echo $this->Form->input('username');
And the validation:
public $validate = array(
'username' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A username is required'
)
),
'province_id' => array(
'rule' => 'notEmpty',
'message' => 'Select something'
)
);
The username field is being validated correctly, but the province_id is being ignored. What can it be?
You should write like this:
public $validate = array(
'username' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A username is required'
)
),
'province_id' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'Select something'
)
)
);
It looks like your form helper declarations are fine.
My experience with Cake shows that the validation is screwy when you start to mix the syntax (one of your fields has a nested array, while the other doesn't). I am sure there is some rhyme or reason to what is going on, but I haven't really dived that deep and usually just do trial and error.
Try this:
public $validate = array(
'username' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'A username is required'
),
'province_id' => array(
'rule' => 'notEmpty',
'required' => true,
'message' => 'Select something'
)
);
Better late then never, try this:
public $validate = array(
'username' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'A username is required'
)
),
'province_id' => array(
'required' => array(
'rule' => array('myOwnValidationRule'),
'message' => 'Select something'
)
)
);
function myOwnValidationRule($data)
{
if($data["province_id"] != 'empty')
{
return true;
}
}
I'm using CakePHP 2.1.1 and whilst my methods which use the form helper, for example my add method in my Users Controller validates correctly, I can't get my mobile_register method in the controller to validate, it saves even when data is missing.
This is my mobile_register method:
public function mobile_register() {
if ($this->request->is('post')) {
$jsonData = file_get_contents("php://input");
if(isset($jsonData) && !empty($jsonData)){
$data = json_decode($jsonData,true);
$data = $this->User->configureUser($data);
$this->User->create();
if($this->User->save($data)){
$jsonResponse = array('status' => 'OK', 'token' => $data['User']['token'], 'message' =>'SUCCESS');
}else{
$errors = $this->User->validationErrors;
$this->log($errors,'errors');
$jsonResponse = array('status' => 'ERROR','message' => $errors);
}
}
}else{
$jsonResponse = array('status' => 'ERROR','message' => 'API method expects POST data');
}
$this->set('response' , $jsonResponse);
}
I've been using curl to test my method and it always saves despite post the following data:
[User] => Array
(
[firstname] => Andy
[token] => cc42030bbb49faf2cf0393418036e44f
[role] => user
)
curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"User":{"firstname":"Andy"}}' url/users/mobile_register
My validation rules in my model are:
public $validate = array(
'username' => array(
'username-1' => array(
'rule' => array('notempty'),
'message' => 'Username is required',
),
'username-2' => array(
'rule' => 'alphaNumeric',
'message' => 'Usernames must only contain letters and numbers.',
),
),
'password' => array(
'password-1' => array(
'rule' => array('notempty'),
'message' => 'Password is required',
),
'password-2' => array(
'rule' => array('between', 5, 15),
'message' => 'Passwords must be between 5 and 15 characters long.',
),
),
'firstname' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'Forename is required'
),
),
'surname' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'Surname is required',
),
),
'email' => array(
'email-1' => array(
'rule' => 'notempty',
'message' => 'Email is required',
),
'email-1' => array(
'rule' => 'email',
'message' => 'Please enter a valid email',
)
)
);
Am I missing something?
Perhaps a better approach to this solution would be to make a good use of the "required" and "allowEmpty" validation options:
CakePhp's data validation
This is what solved my problem, I thought it was related with the way I was requesting the action, but instead it was that I wasn't even setting the fields I wanted to validate.
I figured it out. Basically I learnt that if you don't pass the fields then they will not be validated.
