yii validate an input array of phone numbers - php

Question

I'm working on a multiple contact form in Yii 1.1.16. Where the user can add multiple phone numbers.
Problem is, how would i validate this using Yii's rules()?
<div class="form-group">
<?php
echo $form->labelEx($model,'contacts', array('class'=>'col-md-3 control-label'));
?>
<div class="col-md-9">
<div class="multiple-contact multiple-form-group input-group padding-bottom-10px" data-max="5">
<div class="input-group-btn input-group-select">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span class="concept">Phone</span> <i class="fa fa-caret-down"></i>
</button>
<ul class="dropdown-menu" role="menu">
<li>Phone</li>
<li>Fax</li>
<li>Mobile</li>
</ul>
<?php echo $form->textField($model,'contacts',array('type'=>'text', 'class'=>'input-group-select-val', 'name'=>'contacts[type][]','value'=>'phone')); ?>
</div>
<?php echo $form->textField($model,'contacts',array('size'=>60,'maxlength'=>255, 'name'=>'contacts[value][]','class'=>'form-control')); ?>
<?php echo $form->error($model,'contacts'); ?>
<span class="input-group-btn">
<button type="button" class="btn btn-success btn-add"><i class="fa fa-plus"></i></button>
</span>
</div>
</div>
</div>
i tried using this, but doesn't work
public function rules()
{
return array(
array('contacts[value][]', 'required'),
array('contacts[value][]', 'integerOnly'=>true),
array('contacts[value][]','type','type'=>'array','allowEmpty'=>false)
);
}
Here is a sample Fiddle on how the jQuery side works. I want it to be able to validate with 'enableAjaxValidation'=>true,. Also, when more fields are added, it duplicates the id of the input. and no ajax post is done onblur/onfocus

Answer 1

Use custom validation.
Declare a custom validator in your rules, and define the validation you require in the validator method.
public function rules()
{
return array(
array('contacts', validateContacts),
);
}
public function validateContacts($attribute,$params)
{
if (length($this->contacts) == 0) {
$this->addError($attribute, 'You must add at least one contact!');
}
foreach($this->contacts as $contact) {
// ...
}
}
In your controller, assign the contacts array to the Model field and call the model's validation method. If there are any errors it will display through the line
<?php echo $form->error($model,'contacts'); ?>
in the view.
The controller contains the code to invoke the validation.
$contactModel = new Contact;
// assign the array of contacts to the model
$contactModel->contacts = $POST['myForm]['contacts']
$contactsModel->validate();
$this->render('myform', contactModel);
If you want the validation to happen through Ajax, you need to specify so when creating your form:
$form=$this->beginWidget('CActiveForm', array(
'id'=>'top-websites-cr-form',
'enableAjaxValidation'=>true,
'clientOptions' => array(
'validateOnSubmit'=>true,
'validateOnChange'=>true),
));
In this case your controller can check for ajax forms.
if(isset($_POST['ajax']) && $_POST['ajax']==='branch-form')
{
echo CActiveForm::validate($model);
Yii::app()->end();
}

Answer 2

You should make it a separate model with it's own validation.
Then in your controller you have to validate the main models and the related models separately.
Here is a good guide for such a setup:

To my opinion for best validation regarding phonenumbers you should use libphonenumber php library and there is an extension for it regarding yii framework here http://www.yiiframework.com/extension/libphonenumber/
basic usage:
Yii::setPathOfAlias('libphonenumber',Yii::getPathOfAlias('application.vendors.libphonenumber'));
$phonenumber=new libphonenumber\LibPhone($your_phone_number);
$phonenumber->validate();
for more details regarding usage and capabilities of libphonenumber php library you can find here:

Let us consider you have a model called ContactNo and it looks like
class ContactNo extends CFormModel
{
public $contact;
public function rules()
{
return array(
// your rules
array('contact', 'required'),
array('contact','length','min'=>2)
);
}
/**
* Declares attribute labels.
*/
public function attributeLabels()
{
return array(
'contact'=>'Contact No',
);
}
}
The controller as SiteController and the action Name as actionIndex
Then your controller should look something like this
public function actionIndex()
{
// set how many contact fields you want here
$contactCount = 3;
$models = array();
if(isset($_POST['ContactNo']))
{
$successModels = 0;
foreach($_POST['ContactNo'] as $key=>$value)
{
$model = new ContactNo;
$model->attributes = $value;
if($model->validate()) // this validates your model
$successModels++; // it tells how many contact No.s have been validated
$models[$key]=$model;
}
// if all the contact nos are validated, then perform your task here
if($successModels === $contactCount)
{
// save your models
echo 'models saved';
Yii::app()->end();
}
}
else
{
for($index = 0;$index < $contactCount; $index++)
$models[] = new ContactNo;
}
$params = array();
$params['contactCount']=$contactCount;
$params['models']= $models;
$this->render('index',$params);
}
Now lets Go to view. Obviously the view is index.php and it will be something like
// Include all the initial part required for activeforms
<?php echo $form->errorSummary($models); ?>
<?php foreach ($models as $index=>$model): ?>
<div class="row">
<?php echo $form->labelEx($model,"[{$index}]contact"); ?>
<?php echo $form->textField($model,"[{$index}]contact",array('size'=>60,'maxlength'=>128)); ?>
<?php echo $form->error($model,"[{$index}]contact"); ?>
</div>
<?php endforeach; ?>
// Include the submit button
Hope this helps you or might give you an idea atleast to achieve your goal.
