phpカレンダーは2012年2月2日以降に2013年3月に行く

Question

私は私のホテルの部屋予約システムのためのPHP mysql calnederを持っています。それは私がなぜ知っているのか分からない奇妙な問題を示しています。 2012年2月2日以降は2013年3月に直接行きます。

別の問題は、部屋が予約されているかどうかを示すためにカレンダーを作成することです。

のindex.php：私は23-25から部屋を予約した場合、それは23とここで24は、カレンダーのコードですでなければなりませんwheather 24と25を予約したマーク関数：

 $prev_month = (($month - 1) == 0) ? 12 : $month -1 ; 
     $prev_year = ($prev_month == 12) ? $year - 1 : $year; 
    ?>

    ?> 
    <a href="index.php?month=<?php echo $next_month ?>&year=<?php echo $next_year ?>" class="next"> 
     &lt;&lt;</a> 

ありがとうございました。

Answer 1

：2月の場合

$next_year = ($prev_month == 1) ? $year + 1 : $year; 

を、$prev_monthは1に設定されているので、あなたの$next_yearが$year + 1となっています。それは、このことなら

$next_year = ($month == 12) ? $year + 1 : $year; 

Answer 2

あなたのコードに何があるのか​​正確には分かりませんが、今年 - 2012年 - うるう年と関係があります。

$ days_in_monthなどの変数に2月の29日間のオプションがあることを確認してください。私は第二のスニペットを見てきましたが、私はこれが問題であるかなり確信している

Answer 3

：

私は、あなたがしなければならないすべては、にその行を変更だと思いますか？

<?php 
    $next_month = (($month + 1) == 13) ? 1 : $month + 1 ; 
    $next_year = ($prev_month == 12) ? $year + 1 : $year; 
?>
