我有php显示日历和另一个php检查数据库以查看预订，如果在某一天预订显示“已预订”。在数据库中，我有预订日期和标题的列。我怎么能让它显示数据库中的标题而不是“预订”？
这是显示日历。
<?php
$monthNames = Array("January", "February", "March", "April", "May",
"June", "July", "August", "September", "October", "November", "December");
?>
<?php
if (!isset($_REQUEST["month"]))
$_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"]))
$_REQUEST["year"] = date("Y");
?>
<?php
$cMonth = $_REQUEST["month"];
$cYear = $_REQUEST["year"];
$prev_year = $cYear;
$next_year = $cYear;
$prev_month = $cMonth-1;
$next_month = $cMonth+1;
if ($prev_month == 0 )
{
$prev_month = 12;
$prev_year = $cYear - 1;
}
if ($next_month == 13 )
{
$next_month = 1;
$next_year = $cYear + 1;
}
require("BookingsDB.php");
$myBookingsDB = new BookingsDB();
$bookings = $myBookingsDB->getMonthlyBookings($cMonth,$cYear);
?>

此PHP检查数据库中的预订日期。

$result = mysqli_query($this->con,$sql);
while($row=mysqli_fetch_array($result))
{
$thisBooking = $row['date'];
$thisBookingDateTime = new DateTime($thisBooking);
array_push($this->bookings,$thisBookingDateTime);
}
return $this->bookings;

答案 1 :(得分：0)
我认为你的问题是你需要放置格式才能比较两个日期时间：
if ($thisDate->format('Y-m-d')==$bookingDate->format('Y-m-d'))
{
echo "Booked";
....
}
答案 2 :(得分：0)
除了@ SimonGuichard的回答之外，我建议你从包含getMonthlyBookings和date的{{1}}函数返回一个关联数组。这样，当需要显示时，您不必再次从数据库中选择标题。
activityTitle然后在显示日历的脚本中，您应该这样修改它：
public function getMonthlyBookings($thisMonth,$thisYear) {
$sql = "SELECT date,activityTitle FROM activityEvent WHERE YEAR(date) = $thisYear AND MONTH(date) = $thisMonth";
$result = mysqli_query($this->con,$sql);
while($row=mysqli_fetch_array($result)) {
$this->bookings[] = array('date'=>new DateTime($row['date']), 'activityTitle'=>$row['activityTitle']);
}
return $this->bookings;
}
