[英]PHP - Calculate days between two dates - not working in March and April 2013
[英]php calender goes to march 2013 after february 2012
我的酒店客房預訂系統具有php mysql calneder。 但這顯示了一個奇怪的問題,我不知道為什么。 它不會在2013年之后,並且在2012年2月之后直接進入2013年3月。
另一個問題是我要讓日歷顯示要預訂的房間。 如果我從23-25預定房間,則它標記為24和25小麥,則應分別為23和24。這是壓延機的代碼:

index.php用於上一個下一個功能:
$prev_month = (($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 $prev_year ?>" class="prev"> >></a>
<span class="month"><?php echo date('F',mktime(0,0,0,$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">
<<</a>
在此先感謝所有人。
我只看了第二個片段,但是我很確定這是問題所在:
$next_year = ($prev_month == 1) ? $year + 1 : $year;
如果是2月,則$prev_month
設置為1,因此您的$next_year
變為$year + 1
。
我認為您要做的就是將該行更改為:
$next_year = ($month == 12) ? $year + 1 : $year;
我無法確切地說出代碼中的錯誤是什么,但是我很確定這與今年-2012年-being年有關。
確保您的變量(例如$ days_in_month)在2月有29天的選項。
應該是這個嗎?
<?php
$next_month = (($month + 1) == 13) ? 1 : $month + 1 ;
$next_year = ($prev_month == 12) ? $year + 1 : $year;
?>
