PHP无法读取post值

我无法读取php页面上设置的post值“to”和“From”日期。 任何帮助都将不胜感激。代码如下：-

在代码中，您可以找到我尝试过的三个代码段，但都不起作用。不确定所需的修复

必须使用函数中的参数传递此值，如下所示

function export_excel_csv($stdt1, $enddt1) { // create function with parameter here

}

调用时，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
    } 
} 

事实上，我不知道这个日历类和功能，但我认为您可以做一件事来解决您的问题，如下所示

首先，您可以使用javascript通过使用document.f1.stdt.value和document.f1.enddt.value

对于PHP，您可以使用：
$\u请求[“stdt”]

您也可以参考此链接以获取有关tc_日历的任何帮助


如果需要更多帮助，请告诉我

谢谢
您已经定义了函数范围之外的变量，您无法访问此变量

或者你的问题的解决方案是

function export_excel_csv()
{
   global $stdt1,$enddt1;
......

}

$myCalendar->writeScript（）-此处生成了什么HTML代码？它必须包含名称为的输入标记。类型为？？你能给我确切的代码吗？$myCalendar->writeScript（）将提供一个日历符号，单击它将允许用户选择日期、月份、年份。print\r（$\u POST）将返回所有POST值。如果您得到'stdt'和'enddt'的值，那么使用datetime类对象来转换输入。尝试后，它成功了。。谢谢
