registration form post field as empty - yii

Question

i'm using Yii-user, and have made some modification to the user/views/user/registration.php file.
for some reason even when i fill in firstname and lastname, it still says i left those fields empty. any idea why?
$form=$this->beginWidget('bootstrap.widgets.TbActiveForm', array(
'id'=>'registration-form',
'type'=>'vertical',
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
),
));
<?php echo $form->textField($model,'email', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('email'))); ?>
<?php echo $form->passwordField($model,'password', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('password'))); ?>
<?php echo $form->passwordField($model,'verifyPassword', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('verifyPassword'))); ?>
<p class="text-seperator"> about you </p>
<?php echo $form->textField($profile,'firstname', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('firstname'), 'maxlength'=> 255)); ?>
<?php echo $form->textField($profile,'lastname', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('lastname'), 'maxlength'=> 255)); ?>
and in my user/models/registrationform.php i have this
class RegistrationForm extends User {
public $firstname; //added
public $lastname; //added
public $verifyPassword;
public $verifyCode;
public function rules() {
$rules = array(
array('firstname, lastname, password, verifyPassword, email', 'required'),
array('firstname', 'length', 'max'=>225, 'min' => 3,'message' => UserModule::t("Incorrect First Name (length between 3 and 225 characters).")),
array('lastname', 'length', 'max'=>225, 'min' => 3,'message' => UserModule::t("Incorrect Last Name (length between 3 and 225 characters).")),
.........
}
}
to fill up firstname and last name using the original code they used this...
$profileFields=Profile::getFields();
if ($profileFields) {
foreach($profileFields as $field) {
?>
<!--div class="row"-->
<?php echo $form->labelEx($profile,$field->varname); ?>
<?php
if ($widgetEdit = $field->widgetEdit($profile)) {
echo $widgetEdit;
} elseif ($field->range) {
echo $form->dropDownList($profile,$field->varname,Profile::range($field->range));
} elseif ($field->field_type=="TEXT") {
echo$form->textArea($profile,$field->varname,array('rows'=>6, 'cols'=>50));
} else {
echo $field->varname.'<br />';
echo $form->textField($profile,$field->varname,array('size'=>60,'maxlength'=>(($field->field_size)?$field->field_size:255)));
}
?>
<?php echo $form->error($profile,$field->varname); ?>
<!--/div-->
<?php
}
}

Answer 1

I think you need to change this,
you have passed $model in here:
<?php echo $form->textField($model,'email', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('email'))); ?>
but you have given $profile here:
<?php echo $form->textField($profile,'firstname', array('class' => 'input-block-level', 'placeholder' => $model->getAttributeLabel('firstname'), 'maxlength'=> 255)); ?>
if you check out the generated html, you will notice that the generated input has different name!

i'm not sure why this works (would be great is someone could explain in detail)
but the issue was here..
public function rules() {
$rules = array(
array('firstname, lastname, password, verifyPassword, email', 'required'),
array('firstname', 'length', 'max'=>225, 'min' => 3,'message' => UserModule::t("Incorrect First Name (length between 3 and 225 characters).")),
array('lastname', 'length', 'max'=>225, 'min' => 3,'message' => UserModule::t("Incorrect Last Name (length between 3 and 225 characters).")),
.........
}
}
firstname, lastname when this is removed it works. and it still is set as required.
