Empty Plugin (Widget)

Earlier I shared my empty plugin code. Great for a quick test or maybe even as a starting point for an awesome new plugin. I’ve decided that I also need one for a widget, so here’s that:

Plugin Name: Empty Plugin (Widget)
Plugin URI: https://trepmal.com/
Description: Does nothing - testing only

add_action( 'widgets_init', 'emptypluginwidget_load' ); /* Add our function to the widgets_init hook. */
function emptypluginwidget_load() { register_widget( 'emptypluginwidget' ); } /* Function that registers our widget. */

class emptypluginwidget extends WP_Widget {

	function emptypluginwidget() {
		$widget_ops = array( 'classname' => 'emptypluginwidget', 'description' => 'empty plugin widget' ); /* Widget settings. */
		$control_ops = array( 'width' => 450, 'height' => 250, 'id_base' => 'emptypluginwidget' ); /* Widget control settings. */
		$this->WP_Widget( 'emptypluginwidget', 'Empty Plugin Widget', $widget_ops, $control_ops ); /* Create the widget. */

	function widget( $args, $instance ) {
		extract( $args );

		echo $before_widget; /* Before widget (defined by themes). */

		if ( $instance['title'] ) echo $before_title . $instance['title'] . $after_title; /* Title of widget (before and after defined by themes). */

		echo '<ul>';
		foreach($instance as $name=>$value) {

			echo '<li>' . $name . ': ' . $value . '</li>';
		echo '</ul>';

	function update( $new_instance, $old_instance ) {
		$instance = $old_instance;

		foreach($new_instance as $k=>$v) { $instance[$k] = strip_tags($v); } /* Strip tags (if needed) and update the widget settings. */

		return $instance;

	function form( $instance ) {

		/* Set up some default widget settings. */

		$defaults = array('title' => 'Empty Plugin Widget', 'content' => 'hello world');

		$instance = wp_parse_args( (array) $instance, $defaults );

		echo '<p><label for="'.$this->get_field_id( 'title' ).'">'. 'Title'.'</label><br />
			<input type="text" id="'. $this->get_field_id( 'title' ).'" name="'.$this->get_field_name( 'title' ).'" value="'.$instance['title'].'" /></p>';

		echo '<p><label for="'.$this->get_field_id( 'content' ).'">'. 'Content'.'</label><br />
			<input type="text" id="'. $this->get_field_id( 'content' ).'" name="'.$this->get_field_name( 'content' ).'" value="'.$instance['content'].'" /></p>';

	} //end function
} //end class
