將 MySQL 數據庫中的值顯示到日歷中
[英]Displaying values in a MySQL database into a calendar
問題描述
我目前有一個 MySQL 數據庫，其中有保留。 它有 ArrivalDate 和 DepartureDate。 我正在尋找一種方法，讓它在他們逗留期間的所有日子里將每個預訂的姓名顯示到日歷中，以便輕松查看。 至少有一個關於如何解決這個問題的大綱將不勝感激。
謝謝！
目前，我有以下內容來計算他們逗留的所有天數：
$period = new DatePeriod(
new DateTime($row['ArrivalDate']),
DateInterval::createFromDateString('+1 day'),
new DateTime($row['DepartureDate'])
);
foreach ( $period as $dt ) {
echo $dt->format( 'd-m-Y' ) . "\n";
}

初始樣本數據：
+----+------------+-------------+---------------+
| id | name | arrivalDate | departureDate |
+----+------------+-------------+---------------+
| 1 | John Smith | 2020-07-17 | 2020-07-20 |
| 2 | John Doe | 2020-07-18 | 2020-07-22 |
| 3 | Jack Smith | 2020-07-28 | 2020-08-02 |
+----+------------+-------------+---------------+
3 rows in set (0,00 sec)
大綱是：您可能可以每月在單個 sql 查詢中執行此操作以獲得所需的數據，但我采用了不同的方法。 在 php 中獲取您要顯示的月份（如果未提供，則為當前月份）。 計算那個月的第一天和最后一天 - 做一個周期。 對於該期間的每一天，獲取當天有效的預訂。 現在，您擁有該月的所有日期以及每天的所有預訂，您可以根據需要顯示它。 還計算上個月和下個月並顯示此信息，以便您可以瀏覽下個月/上個月。
我把它作為一個接受一個月作為參數的腳本來做，如果沒有提供參數，它會顯示當前月份。
<?php
// database and query
$db = new PDO("mysql:host=localhost;dbname=calendar", 'z', 'z');
function selectFromDate(DateTime $date): array {
global $db;
$q = $db->prepare("SELECT * FROM reservations WHERE arrivalDate <= :date AND departureDate >= :date");
$q->execute([':date' => $date->format('Y-m-d')]);
return $q->fetchAll(PDO::FETCH_OBJ);
}
// initial dates
$yearMonthDate = new DateTime();
if ($argc > 1) {
$yearMonthDate = new DateTime($argv[1]);
}
$yearMonth = $yearMonthDate->format('Y-m');
$nextYearMonth = (clone $yearMonthDate)->modify('first day of next month')->format('Y-m');
$previousYearMonth = (clone $yearMonthDate)->modify('first day of previous month')->format('Y-m');
$firstDayDate = (clone $yearMonthDate)->modify('first day of this month');
$lastDayDate = (clone $yearMonthDate)->modify('last day of this month');
$monthPeriod = new DatePeriod($firstDayDate, new DateInterval('P1D'), $lastDayDate);
// fetch data
$monthData = [];
foreach ($monthPeriod as $date) {
$dayInfo = new stdClass();
$dayInfo->date = $date->format('Y-m-d');
$dayInfo->reservations = [];
foreach (selectFromDate($date) as $reservation) {
$dayInfo->reservations[] = $reservation->name;
}
$monthData[] = $dayInfo;
}
var_dump($monthData);
// display
echo 'Displaying: '.$yearMonth.PHP_EOL;
foreach ($monthData as $day) {
echo ' '.$day->date.': '.join($day->reservations, ', ');
echo PHP_EOL;
}
echo 'Previous month: '.$previousYearMonth. ', next month: '.$nextYearMonth.PHP_EOL;
你這樣稱呼它： file.php並像這樣得到 output （沒有參數 - 當月的 output ）：

如您所見，它是一個包含 30 個元素的數組（一個月中的每一天）。 每個元素都包含這一天的日期和預訂，因此現在可以輕松地以您認為合適的方式顯示它（例如 html）。
如果你想在下個月看到這樣的調用： file.php 2020-08 ，你會得到這個 output：

如果您想要瀏覽器版本，只需通過鏈接參數傳遞YYYY-MM參數。 如果要從日歷中排除出發日期，請修改查詢departureDate >:date
