You can add additional attributes and rules to the model. You don't need to only use attributes that are directly related to fields in the database table. Let's look at a basic example. You have a custom (custom) table that has the following fields:
- ID
- password
And you have another table that stores information about the user profile (UserProfile), which has the structure:
- ID
- user_id
- Country
When a user creates their account, you will have a form that captures their information. Your user model will have rules like:
array('email, password', 'required'),
array('email', 'unique', 'message'=>'Email already in use'),
...
You can add a country attribute to your user model like this:
class User extends CActiveRecord {
public $country;
...
And then in your rules, you can add a new attribute:
array('email, password, country', 'required'),
array('email', 'unique', 'message'=>'Email already in use'),
...
The country attribute will now be part of your user model. Now you can add this to your form:
<?php echo $form->dropDownList($model,'country',CHtml::listData(Country::model()->findAll(),'id','country_name'),array('empty'=>'-- select a country --')); ?>
Now, when submitting the form, the method $model->validate()
will check the country field. You can save this manually into a second model (UserProfile), for example:
if(isset($_POST['User'])){
if ($model->validate()){
$user_profile = new UserProfile;
$user_profile->user_id = $model->id;
$user_profile->country = $model->country;
$user_profile->save();
...
Hope this answers your question.
