How to link event location to venue website

I received this request on the WordPress.org forum:

Is there a way to assign a link to the “location” field? I’d like to list all events for a specific production on a page and have the “location” field linkable to the theatre address.

By default your events look something like this:

Default event HTML — The default event output where the title and thumbnail link to the production detail page.

Now add the following code to your (child)theme’s functions.php file:

	<?php
	/**
	* Adds a new 'Venue URL' field to the event editor.
	*
	* @param array $fields The current fields of the event editor.
	* @return array The new fields of the event editor.
	*/
	function wpt_event_editor_add_venue_url_field($fields) {
	$new_fields = array();
	foreach($fields as $field) {
	$new_fields[] = $field;
	if ('venue' == $field['id']) {
	$new_fields[] = array(
	'id' => 'venue_url',
	'title' => 'Venue URL',
	'edit' => array(
	'placeholder' => 'http://',
	),
	);
	}
	}
	return $new_fields;
	}
	add_filter( 'wpt/event_editor/fields', 'wpt_event_editor_add_venue_url_field');

	/**
	* Adds a link to the venue HTML if the venue URL is set.
	*
	* @param string $html The current venue HTML.
	* @param WPT_Event $event The event.
	* @return string The new venue HTML.
	*/
	function wpt_event_add_venue_url($html, $event) {
	$venue_url = $event->custom('venue_url');
	if (!empty($venue_url)) {
	$html = '<a href="'.esc_attr($venue_url).'" target="_blank" style="display: block;">'.$html.'</a>';
	}
	return $html;
	}
	add_filter( 'wpt_event_location_html', 'wpt_event_add_venue_url', 10, 2);
