* An example for creating required fields only if payment type is CreditCard:
*
*
* new CustomRequiredFields(
* array(
* "PaymentMethod",
* array(
* "js" => "
* for( var i = 0; i <= this.elements.PaymentMethod.length -1; i++){
* if(this.elements.PaymentMethod[i].value == 'CC' && this.elements.PaymentMethod[i].checked == true){
* require('CardHolderName');
* require('CreditCardNumber');
* require('DateExpiry');
* }
* }
*
* ",
* "php" => 'if($data[PaymentMethod] == "CC") {
* $this->requireField($field,"$field is required","required");
* $this->requireField("CardHolderName", $data);
* $this->requireField("CreditCardNumber", $data);
* $this->requireField("DateExpiry", $data);
* }',
* )
* )
* );
*
*
* And example for confirming mobile number and email address:
*
*
* $js = << $js, 'php' => 'return true;'), array('js' => $js2, 'php'=>'return true;')));
