I have a Yii form accept first name
, last name
and email
from user. Using an add more
link, users can add multiple rows of those three elements.
For email validation, unique
and required
are set in model rules and everything works fine. I am using JavaScript to create addition row on clicking add more
link.
Problem
On the first row my values are John, Newman, johnnewman@gmail.com
and the second row, i'm entering Mathew, Heyden, johnnewman@gmail.com
. In this case email address is duplicated. None of the validation rules ( require
and unique
) is capable of validating this. Can some one suggest a better method to validate this ?
Update: I created a custom validation function and i guess this is enough to solve my problem. Can someone tell me how to access the whole form data
/ post data
in a custom validation function ?
public function uniqueOnForm($attribute){
// This post data is not working
error_log($_REQUEST, true);
$this->addError($attribute, 'Sorry, email address shouldn\'t be repeated');
}
You can try this:
<?php
public function rules()
{
return array(
array('first_name', 'checkUser')
);
}
public function checkUser($attribute)
{
if($this->first_name == $this->other_first_name){
$this->addError($attribute, 'Please select another first name');
}
}
?>
You can also look into this extension
You can write custom validator:
//protected/extensions/validators
class UniqueMailValidator extends CValidator
{
/**
* @inheritdoc
*/
protected function validateAttribute($object, $attribute)
{
$record = YourModel::model()->findAllByAttributes(array('email' => $object->$attribute));
if ($record) {
$object->addError($attribute, 'Email are exists in db.');
}
}
}
// in your model
public function rules()
{
return array(
array('email', 'ext.validators.UniqueMailValidator'),
...
Or better try to use THIS
public function rules(){
return array(
//other rules
array('email', 'validEmail'),
)
}
public function validEmail($attribute, $params){
if(!empty($this->email) && is_array($this->email)){
$isduplicate = $this->isDuplicate($this->email);
if($isduplicate){
$this->addError('email', 'Email address must be unique!');
}
}
}
private function isDuplicate($arr){
if(count(array_unique($arr)) < count($arr)){
return true;
}
else {
return false;
}
}
because you are using tabular input (multiple row) , so make sure input field as an array. might be like this :
<?php echo $form->textField($model, 'email[]'); ?>
