I need to have a PHP / HTML / JS / CSS website to find close-by hotels and link ( affiliate using booking.com or kayak for instance ) to their booking pages. I want a visitor to enter a street address + optional Conference name and date. If the conference name is entered, it is stored in DB for fast retrieval. Once entered -> the addess is geo coordinated found ( using https://apidocs.geoapify.com/ or google maps API ). This is also stored in the DB to avoid high API pricings and speed up the site. Also in the input fields: Amount of persons, check-in day, check-out day. Also : pre filled: Walking. Other options: public transport, bike. Also: time to travel: 10 minutes , 20 minutes (default option), 45 minutes Also: some filtering for hotel type or hotel stars/ratings. (to be discussed) It will show a map with centered = the destination address. It will show Isochrones distances based on the type of transport and time to travel. You will also store the API response to geoapify. Meanwhile it will also show hotel "pins" in the map. With basic info on mousover or click. They will lead to the affiliate page of booking.com or Kayak. At the moment I only have an API key for geoapify, and if needed also for google maps (but they also do this https://www.geoapify.com/geocoding-api/ ). Site language: English.
