I made an dynamic sidebar widget.
Code modifications:
Add to cd-qotd.php:
include_once('cd-qotd-widget.php'); /* Added */right after global $wpdb;
Add file cd-qotd-widget.php that reads:
<?php
class QotdWidget extends WP_Widget {
/** constructor */
function QotdWidget() {
parent::WP_Widget(false, $name = 'Quote of the day Widget');
}
/** @see WP_Widget::widget */
function widget($args, $instance) {
extract( $args );
$title = apply_filters('widget_title', empty( $instance['title'] ) ? 'Quote of the Day' : $instance['title']);
echo $before_widget . $before_title . $title . $after_title;
cd_qotd_quote();
echo $after_widget;
}
/** @see WP_Widget::update */
function update($new_instance, $old_instance) {
$instance = $old_instance;
$instance['title'] = strip_tags($new_instance['title']);
return $instance;
}
/** @see WP_Widget::form */
function form($instance) {
//Defaults
$title = esc_attr( $instance['title'] );
?>
<p><label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title:'); ?> <input class="widefat" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo $title; ?>" /></label></p>
<?php
}
} // class QotdWidget
// register QotdWidget widget
add_action('widgets_init', create_function('', 'return register_widget("QotdWidget");'));
?>
