Question

I have a form that works perfectly. If filled in and validation passes, it takes you to another page which is also a form. However, when the user goes to this form, I want to display a “warning” at the top. I know drupal has drupal_set_message function, but what does YII have to accomplish something similar?

Answer 1

Yii uses something like

Yii::app()->user->setFlash('notice', 'This is your notice');

In the view you need to add something like this then:

foreach(Yii::app()->user->getFlashes() as $key => $message) {
    echo '<div class="flash-' . $key . '">' . $message . "</div>\n";
}
