php - 可作为链接点击的行

Question

我用 PHP 制作了一个日历，现在我试图将<td></td>可点击的链接设置为链接，而不是像现在这样在其中包含文本

else echo "<td align='center' 
               valign='middle' 
               height='20px' 
               style='background-color:gray;'>

                    <a href='days.php?day=". ($i - $startday + 1) . "&month=$cMonth&year=$cYear'>".
                         ($i - $startday + 1).
                    "</a>
           </td>";

像这样的工作：

<td onclick="document.location = 'link.php';">&nbsp;</td>

但我不能让它在日历中工作

这是网站上的所有代码：

<?php
$monthNames = Array("January", "February", "March", "April", "May", "June", "July",         "August", "September", "October", "November", "December");
?>
<?php
if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");
?>
<?php
$cMonth = $_REQUEST["month"];
$cYear = $_REQUEST["year"];
$prev_year = $cYear;
$next_year = $cYear;
$prev_month = $cMonth-1;
$next_month = $cMonth+1;
if ($prev_month == 0 ) {
$prev_month = 12;
$prev_year = $cYear - 1;
}
if ($next_month == 13 ) {
$next_month = 1;
$next_year = $cYear + 1;
}
?>

使用一些 JavaScript 对您的代码进行微小的更改。

<?php
$monthNames = Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
?>
<?php
if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");
?>
<?php
$cMonth = $_REQUEST["month"];
$cYear = $_REQUEST["year"];
$prev_year = $cYear;
$next_year = $cYear;
$prev_month = $cMonth-1;
$next_month = $cMonth+1;
if ($prev_month == 0 ) {
$prev_month = 12;
