/**
* CActiveForm provides a set of methods that can help to simplify the creation
* of complex and interactive HTML forms that are associated with data models.
*
* The 'beginWidget' and 'endWidget' call of CActiveForm widget will render
* the open and close form tags. Most other methods of CActiveForm are wrappers
* of the corresponding 'active' methods in {@link CHtml}. Calling them in between
* the 'beginWidget' and 'endWidget' calls will render text labels, input fields,
* etc. For example, calling {@link CActiveForm::textField}
* would generate an input field for a specified model attribute.
*
* What makes CActiveForm extremely useful is its support for data validation.
* CActiveForm supports data validation at three levels:
* <ul>
* <li>server-side validation: the validation is performed at server side after
* the whole page containing the form is submitted. If there is any validation error,
* CActiveForm will render the error in the page back to user.</li>
* <li>AJAX-based validation: when the user enters data into an input field,
* an AJAX request is triggered which requires server-side validation. The validation
* result is sent back in AJAX response and the input field changes its appearance
* accordingly.</li>
* <li>client-side validation (available since version 1.1.7):
* when the user enters data into an input field,
* validation is performed on the client side using JavaScript. No server contact
* will be made, which reduces the workload on the server.</li>
* </ul>
*
* All these validations share the same set of validation rules declared in
* the associated model class. CActiveForm is designed in such a way that
* all these validations will lead to the same user interface changes and error
* message content.
*
* To ensure data validity, server-side validation is always performed.
* By setting {@link enableAjaxValidation} to true, one can enable AJAX-based validation;
* and by setting {@link enableClientValidation} to true, one can enable client-side validation.
* Note that in order to make the latter two validations work, the user's browser
* must has its JavaScript enabled. If not, only the server-side validation will
* be performed.
*
* The AJAX-based validation and client-side validation may be used together
* or separately. For example, in a user registration form, one may use AJAX-based
* validation to check if the user has picked a unique username, and use client-side
* validation to ensure all required fields are entered with data.
* Because the AJAX-based validation may bring extra workload on the server,
* if possible, one should mainly use client-side validation.
*
* The AJAX-based validation has a few limitations. First, it does not work
* with file upload fields. Second, it should not be used to perform validations that
* may cause server-side state changes. Third, it is not designed
* to work with tabular data input for the moment.
*
* Support for client-side validation varies for different validators. A validator
* will support client-side validation only if it implements {@link CValidator::clientValidateAttribute}
* and has its {@link CValidator::enableClientValidation} property set true.
* At this moment, the following core validators support client-side validation:
* <ul>
* <li>{@link CBooleanValidator}</li>
* <li>{@link CCaptchaValidator}</li>
* <li>{@link CCompareValidator}</li>
* <li>{@link CEmailValidator}</li>
* <li>{@link CNumberValidator}</li>
* <li>{@link CRangeValidator}</li>
* <li>{@link CRegularExpressionValidator}</li>
* <li>{@link CRequiredValidator}</li>
* <li>{@link CStringValidator}</li>
* <li>{@link CUrlValidator}</li>
* </ul>
*
* CActiveForm relies on CSS to customize the appearance of input fields
* which are in different validation states. In particular, each input field
* may be one of the four states: initial (not validated),
* validating, error and success. To differentiate these states, CActiveForm
* automatically assigns different CSS classes for the last three states
* to the HTML element containing the input field.
* By default, these CSS classes are named as 'validating', 'error' and 'success',
* respectively. We may customize these CSS classes by configuring the
* {@link clientOptions} property or specifying in the {@link error} method.
*
* The following is a piece of sample view code showing how to use CActiveForm:
*
* <pre>
* <?php $form = $this->beginWidget('CActiveForm', array(
* 'id'=>'user-form',
* 'enableAjaxValidation'=>true,
* 'enableClientValidation'=>true,
* 'focus'=>array($model,'firstName'),
* )); ?>
*
* <?php echo $form->errorSummary($model); ?>
*
* <div class="row">
* <?php echo $form->labelEx($model,'firstName'); ?>
* <?php echo $form->textField($model,'firstName'); ?>
* <?php echo $form->error($model,'firstName'); ?>
* </div>
* <div class="row">
* <?php echo $form->labelEx($model,'lastName'); ?>
* <?php echo $form->textField($model,'lastName'); ?>
* <?php echo $form->error($model,'lastName'); ?>
* </div>
*
* <?php $this->endWidget(); ?>
* </pre>
*
* To respond to the AJAX validation requests, we need the following class code:
* <pre>
* public function actionCreate()
* {
* $model=new User;
* $this->performAjaxValidation($model);
* if(isset($_POST['User']))
* {
* $model->attributes=$_POST['User'];
* if($model->save())
* $this->redirect('index');
* }
* $this->render('create',array('model'=>$model));
* }
*
* protected function performAjaxValidation($model)
* {
* if(isset($_POST['ajax']) && $_POST['ajax']==='user-form')
* {
* echo CActiveForm::validate($model);
* Yii::app()->end();
* }
* }
* </pre>
*
* In the above code, if we do not enable the AJAX-based validation, we can remove
* the <code>performAjaxValidation</code> method and its invocation.

* <ul>
* <li>ajaxVar: string, the name of the parameter indicating the request is an AJAX request.
* When the AJAX validation is triggered, a parameter named as this property will be sent
* together with the other form data to the server. The parameter value is the form ID.
* The server side can then detect who triggers the AJAX validation and react accordingly.
* Defaults to 'ajax'.</li>
* <li>validationUrl: string, the URL that performs the AJAX validations.
* If not set, it will take the value of {@link action}.</li>
* <li>validationDelay: integer, the number of milliseconds that an AJAX validation should be
* delayed after an input is changed. A value 0 means the validation will be triggered immediately
* when an input is changed. A value greater than 0 means changing several inputs may only
* trigger a single validation if they happen fast enough, which may help reduce the server load.
* Defaults to 200 (0.2 second).</li>
* <li>validateOnSubmit: boolean, whether to perform AJAX validation when the form is being submitted.
* If there are any validation errors, the form submission will be stopped.
* Defaults to false.</li>
* <li>validateOnChange: boolean, whether to trigger an AJAX validation
* each time when an input's value is changed. You may want to turn this off
* if it causes too much performance impact, because each AJAX validation request
* will submit the data of the whole form. Defaults to true.</li>
* <li>validateOnType: boolean, whether to trigger an AJAX validation each time when the user
* presses a key. When setting this property to be true, you should tune up the 'validationDelay'
* option to avoid triggering too many AJAX validations. Defaults to false.</li>
* <li>hideErrorMessage: boolean, whether to hide the error message even if there is an error.
* Defaults to false, which means the error message will show up whenever the input has an error.</li>
* <li>inputContainer: string, the jQuery selector for the HTML element containing the input field.
* During the validation process, CActiveForm will set different CSS class for the container element
* to indicate the state change. If not set, it means the closest 'div' element that contains the input field.</li>
* <li>errorCssClass: string, the CSS class to be assigned to the container whose associated input
* has AJAX validation error. Defaults to 'error'.</li>
* <li>successCssClass: string, the CSS class to be assigned to the container whose associated input
* passes AJAX validation without any error. Defaults to 'success'.</li>
* <li>validatingCssClass: string, the CSS class to be assigned to the container whose associated input
* is currently being validated via AJAX. Defaults to 'validating'.</li>
* <li>errorMessageCssClass: string, the CSS class assigned to the error messages returned
* by AJAX validations. Defaults to 'errorMessage'.</li>
* <li>beforeValidate: function, the function that will be invoked before performing ajax-based validation
* triggered by form submission action (available only when validateOnSubmit is set true).
* The expected function signature should be <code>beforeValidate(form) {...}</code>, where 'form' is
* the jquery representation of the form object. If the return value of this function is NOT true, the validation
* will be cancelled.
*
* Note that because this option refers to a js function, you should prefix the value with 'js:' to prevent it
* from being encoded as a string. This option has been available since version 1.1.3.</li>
* <li>afterValidate: function, the function that will be invoked after performing ajax-based validation
* triggered by form submission action (available only when validateOnSubmit is set true).
* The expected function signature should be <code>afterValidate(form, data, hasError) {...}</code>, where 'form' is
* the jquery representation of the form object; 'data' is the JSON response from the server-side validation; 'hasError'
* is a boolean value indicating whether there is any validation error. If the return value of this function is NOT true,
* the normal form submission will be cancelled.
*
* Note that because this option refers to a js function, you should prefix the value with 'js:' to prevent it
* from being encoded as a string. This option has been available since version 1.1.3.</li>
* <li>beforeValidateAttribute: function, the function that will be invoked before performing ajax-based validation
* triggered by a single attribute input change. The expected function signature should be
* <code>beforeValidateAttribute(form, attribute) {...}</code>, where 'form' is the jquery representation of the form object
* and 'attribute' refers to the js options for the triggering attribute (see {@link error}).
* If the return value of this function is NOT true, the validation will be cancelled.
*
* Note that because this option refers to a js function, you should prefix the value with 'js:' to prevent it
* from being encoded as a string. This option has been available since version 1.1.3.</li>
* <li>afterValidateAttribute: function, the function that will be invoked after performing ajax-based validation
* triggered by a single attribute input change. The expected function signature should be
* <code>beforeValidateAttribute(form, attribute, data, hasError) {...}</code>, where 'form' is the jquery
* representation of the form object; 'attribute' refers to the js options for the triggering attribute (see {@link error});
* 'data' is the JSON response from the server-side validation; 'hasError' is a boolean value indicating whether
