Trigger Yii field validation onchange of another field

Question

I have two related fields in a Yii model. They are items_per and items_period.

items_per is an integer that reflects how many items to be processed

Answer 1

I created the following javascript function, which I manually call when changing specific fields. It performs ajax validation on all form elements.

/**
 * @author marcovtwout
 * Force performing full ajax validation on given form.
 * @param Object $form jQuery form object
 */
performFullAjaxValidation = function($form){
    var settings = $form.data("settings");
    $.each(settings.attributes, function () {
        this.status = 2; // force ajax validation
    });
    $form.data("settings", settings);

    // trigger ajax validation
    $.fn.yiiactiveform.validate($form, function (data) {
        $.each(settings.attributes, function () {
            $.fn.yiiactiveform.updateInput(this, data, $form);
        });
        $.fn.yiiactiveform.updateSummary($form, data);
    });
}
