无法使用POST方法将数据从API发送到AJAX

Question

I am having very weird problem. My ajax request, returns only the strings without the actual values in it / except where the class ID is, only there it retrieves the postID /. I am not sure where the problem is but here is my code:

JQUERY:

var roomID = jQuery(this).closest('li').attr('id');
        jQuery.ajax({
            url: '/wp-json/api/hotelRooms',
            data: {
                'post_id':roomID
            },
            type: 'POST',
            dataType: 'json',
            success: function (data) {
            jQuery(".rooms-popups-container").empty();
            jQuery(".rooms-popups-container").append(data);
            console.log(data);
            },
            error: function hotelRooms(data) {
                console.log('Error:', data);
            }
        });

PHP: / not posting all the code just small part of it

add_action( 'rest_api_init', function (){
    register_rest_route( 'api', '/hotelRooms', array(
        'methods' => 'POST',
        'callback' => 'hotelRooms',
    ));
});

function hotelRooms($returndata){
  $postID = $_POST['post_id'];
  $posttitle = get_the_title($postID);
  $postcontent = get_post_field('post_content', $postID);
  $galleries = get_post_meta( $postID, '_hb_gallery', true );
  $returndata = "";
  $returndata .= '<div class="hb_single_room room-popup" id="popup-room-'.$postID.'">
      <div class="summary entry-summary">
          <div class="title">
              <h4>
                  <a href="#">'. $posttitle .'</a>
                  <img class="close-room-popup" room_id="'.$postID.'" alt="x" src="https://www.micasas.it/wp-content/uploads/2018/03/x.png">
              </h4>
          </div>';
  return $returndata;
}

In POSTMAN it returns the actual values and everything i need -> http://prntscr.com/me517n but in the Jquery returns only part of the information: http://prntscr.com/me51e0

Ok i get it

You are currently sending room-<id> from your js instead of <id> that's why your functions are returning empty values. You can use something like the following in hotelRooms()

$postID = explode("room-",$_POST['post_id'])[1];
