我可以重定向到我当前的php页面，但具有不同的功能（基于用户的决定）？ [关闭]

Basically, I have a function that creates a calendar and only needs modifying to display the next/prev month in a calendar ie. createCal($nextM, $y) and I just need to call this function with the new parameters whenever someone clicks a link. I don't think we can use javascript so i'd like to avoid that if at all possible.

Pretty much, all i want to do is something like--

if (user clicks on 'next') then 
    createCal($nextM, $y) 
else if (user clicks on 'prev') then 
    createCal($prevM, $y)

^is there anything I can do like this above? Thanks!

There are lots of ways to do this. One suggestion is to use a $_GET parameter to send the month you want to display. Something like:

PHP:

if (isset($_GET['month'])) {
     createCal($_GET['month'], $y)
}

HTML:

<a href='cal.php?month=<?=$nextM?>'>Next Month</a>
<a href='cal.php?month=<?=$prevM?>'>Prev Month</a>

Depending on your system, you might also want to send the year - for situations where next month is Jan of the next year, or previous month is Dec last year...
