I have a bookings table represented by the code below, i wish to add a mouseover function to display customer details eg. number of persons in a room,meal plan etc.All data is fetched from the database.How can i go about it? 

<?php
    session_start();
    if (!isset($_SESSION["user"])) {
        header("location:index.php");
    }

    require_once(__DIR__ . '/db.php');

    //Get all the rooms from the database
    $roomsSQL  = "SELECT TRoom FROM room";

    $days = 30;

    $roomsArray = array();

    $roomsResult = mysqli_query($con, $roomsSQL);

    $roomsArray = array();

    while ($row = mysqli_fetch_assoc($roomsResult)) {
        array_push($roomsArray, $row);
    }

    //Get all date bound bookings
    date_default_timezone_set('Africa/Nairobi');

    $startDate = $_GET['start_date'] ?? date("Y-m-d");
    $endDate = date('Y-m-d', strtotime($startDate . " + $days days"));

    $sql = "SELECT tbl_events.id, tbl_events.title, tbl_events.start, tbl_events.end, tbl_events.color, room.TRoom\n
    FROM tbl_events\n
    INNER JOIN roombook\n
    ON tbl_events.roombook_id =  roombook.id\n
    INNER JOIN room\n
    ON roombook.TRoom = room.TRoom\n
    WHERE tbl_events.start BETWEEN '$startDate' AND '$endDate'\n
    OR (tbl_events.start < '$startDate' AND tbl_events.end > '$startDate');";

    $result = mysqli_query($con, $sql);

    $bookingsArray = array();

    while ($row = mysqli_fetch_assoc($result)) {
        array_push($bookingsArray, $row);
    }

    /**

                }
            }

I didn't read all your code, but on a macro-level you have a couple choices. Either get all the information on page load and use PHP to put it into JS variables or HTML data attributes, or use AJAX on the mouse over event and do it dynamically (slower, but IMO a better choice).

This thread is more than a year old. Please don't revive it unless you have something important to add.
