For some reason, you don’t want to use our booking system but still use the search form. So you want to redirect to another website when clicking the Check Availability button. I’ll guide you on how to custom this:
1. Setup Child theme.
Hotel WP provides a child theme after you imported demo data. Install Hotel WP Child in Dashboard >> Hotel WP >> Child Themes.
2. Deploy In Child theme.
In child theme, create folder hotel-wp-child/wp-hotel-booking/search and copy file search.php to the folder (hotelwp-child/wp-hotel-booking/search/search.php)
In the file search.php, replace line 56 (file search-form.php line 67 in Hotel Booking version 1.9.7.x): <button type="submit"><?php esc_html_e( 'Check Availability', 'hotel-wp' ); ?></button>
to <a target="_blank" href="link-website"><?php esc_html_e('Check Availability', 'hotel-wp'); ?></a>
See the screenshot http://prntscr.com/iofdz8
3. Deploy In Plugin Hotel Shortcodes
In folder /wp-content/plugins/thim-hotel-wp-shortcodes/hb-rooms-search/tpl/default.php replace line 179:
$html .= '<button type="submit">' . esc_html__( 'Check Availability', 'hotel-wp' ) . '</button>';
to $html .= '<button><a target="_blank" href="link-you-want">' . esc_html__( 'Check Availability', 'hotel-wp' ) . '</a></button>';
Done! Now your site will redirect to another website when click the Check Availability button.
