我无法读取在php页面上设置的帖子值“To”和“From”日期。 任何帮助，将不胜感激。这是代码： -
在代码中你可以找到我尝试过的三个代码片段，但没有一个有效。不确定需要修复。

您必须使用像
这样的函数中的参数传递此值function export_excel_csv($stdt1, $enddt1) { // create function with parameter here
}
在打电话时你必须传递相关参数
if($_SERVER['REQUEST_METHOD']=="POST") // Code Snippet 3
{
if(isset($_POST['download']))
{
$stdt1=$_POST['stdt'];
$enddt1=$_POST['enddt'];
export_excel_csv($stdt1, $enddt1); // pass parameter here
}
}

实际上我不知道这个日历类和功能，但我认为你可以做一件事来解决你的问题，如下所示，
首先，您可以使用 document.f1.stdt.value ＆amp;来使用javascript来获取此值。 document.f1.enddt.value
对于PHP，您可以使用：$_REQUEST["stdt"];
您也可以参考此链接获取有关tc_calendar
的任何帮助http://www.triconsole.com/php/calendar_datepicker.php
如果需要更多帮助，请告诉我。

您已在函数范围之外定义变量，您无法访问它。 See the PHP manual for more details
或解决您的问题
function export_excel_csv()
{
global $stdt1,$enddt1;
......
}
