PHP日历将于2012年2月之后进入2013年3月

[英]php calender goes to march 2013 after february 2012

问题描述

我的酒店客房预订系统具有php mysql calneder。 但这显示了一个奇怪的问题，我不知道为什么。 它不会在2013年之后，并且在2012年2月之后直接进入2013年3月。

另一个问题是我要让日历显示要预订的房间。 如果我从23-25预定房间，则它标记为24和25小麦，则应分别为23和24。这是压延机的代码：

function.php 

     function draw_calendar($month,$year){

 }

index.php用于上一个下一个功能： 

     $prev_month = (($month - 1) == 0) ? 12 : $month -1 ;
        $prev_year = ($prev_month == 12) ? $year - 1 : $year;
     ?>
   <h2 class="calender">
     <a href="index.php?month=<?php echo $prev_month ?>&year=<?php echo $prev_year ?>" class="prev"> &gt;&gt;</a>


    <span class="month"><?php echo  date('F',mktime(0,0,0,$month,1,$year)).' '.$year.''; ?></span>
    <?php 
        $next_month = (($month + 1) == 13) ? 1 : $month + 1 ;
        $next_year  = ($prev_month == 1) ? $year + 1 : $year;
     ?>
     <a href="index.php?month=<?php echo $next_month ?>&year=<?php echo $next_year ?>" class="next"> 
        &lt;&lt;</a>

在此先感谢所有人。

我只看了第二个片段，但是我很确定这是问题所在： 

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

如果是2月，则$prev_month设置为1，因此您的$next_year变为$year + 1 。

我认为您要做的就是将该行更改为： 

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

我无法确切地说出代码中的错误是什么，但是我很确定这与今年-2012年-being年有关。

确保您的变量（例如$ days_in_month）在2月有29天的选项。

应该是这个吗？ 

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