There are two ways of placing the Booking Engine Button on a Wordpress website: Using a WordPress widget or by placing the button with HTML only (this page).
This page gives you instructions on placing the button with HTML only.
If you want to place the Booking Engine Button on a page without the “widget-ready-areas”, you can place the button between your regular page text using HTML only.
Placing HTML
To place HTML on a page:
Go to the Wordpress Dashboard.
Go to “Pages”.
Click on "Edit”.
Click on the three dots on the right above "More tools & options".
Click on "Code editor".
Put the HTML code mentioned in the next paragraph, on the desired spot in the text.
Click on "Update" at the top right.
Click on "View page" at the bottom left.
HTML code
Replace {hotel} with your hotel ID and replace {language} with the correct language code.
<form method="post" action="https://scripts.hoteliers.com/api/v1/book-form" target="_blank" class="hoteliers-book-form">
<input type="hidden" name="hotel" value="{hotel}">
<input type="hidden" name="lang" value="{language}">
<button type="submit" class="hoteliers-book-form__button">Book now</button>
</form>
