Boutons radio non sauvegardés Widget

Question

Comment puis-je sauvegarder mon "état actuel" (fonction formulaire) et le montrer dans le frontend (fonction widget)?

// Create the widget output. 
public function widget($args, $instance) { 
    $title = apply_filters('widget_title', $instance[ 'title' ]); 
    $employment = apply_filters('widget_title', $instance[ 'employment' ]); 
    echo $args['before_widget'] . $args['before_title'] . $title . $args['after_title']; ?> 
    <p>Current state of employment: <?php echo $employment ?></p> 
    <?php echo $args['after_widget']; 
} 


// Create the admin area widget settings form. 
public function form($instance) { 
    $title = ! empty($instance['title']) ? $instance['title'] : ''; 
    $employment = ! empty($instance['employment']) ? $instance['employment'] : 'help'; 
    ?> 
    <p> 
    <label> Current State of employment:</label><br> 
    <input for="<?php echo $this->get_field_id('employment'); ?>" type="radio" name="employment" value="employed"> Employed<br> 
    <input for="<?php echo $this->get_field_id('employment'); ?>" type="radio" name="employment" value="unemployed"> Unemployed<br> 
</p> 
<?php 
}
