How Can I save my current "state of employment" (form function) and show it in the frontend (widget function) ?
// 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 $this->get_field_id( 'employment' ); ?>" type="radio" name="employment" value="unemployed"> Unemployed<br>
</p>
<?php
}
Try this code
<input type="radio" <?php checked($instance[ 'employment' ] ,'employment'); ?> id="<?php echo $this->get_field_id( 'employment' ); ?>" value="employment" name="<?php echo $this->get_field_name( 'employment' ); ?>" ><br>
<input type="radio" <?php checked($instance[ 'employment' ] ,'unemployed'); ?> id="<?php echo $this->get_field_id( 'unemployed' ); ?>" value="unemployed" name="<?php echo $this->get_field_name( 'employment' ); ?>" >
