我想在操作方法中传递参数，因为我无法在标头中传递参数。
<form name="mailinglist1" method="post" action="report1.php" >
以这种形式，我正在使用下载按钮来连接我的报告（html）
$st1= 3106530;
header('Location: report1.php?num='.$st1 );

pdf已下载，但未在report1.php中获得$ _GET（'num'）。如何知道是否传递参数。我附加了我页面的完整编码。
答案 0 :(得分：2)
您通过POST方法发送表单，您的数据将通过邮寄发送。
通过$ _POST更改$ _GET或将表单方法更改为GET。
答案 1 :(得分：-1)
请尝试下面的代码，这将帮助您获取PHP文件中的值。
<?php
include("config/config.php");
include("header.php");
if(isset($_POST['search'])){
$query1 = mysql_query("SELECT * from staff where staff_code=".$_POST['staff']);
$row = mysql_fetch_array($query1);
$query2=mysql_query("SELECT * from master_tab where
deo_code =".$_POST['staff']
);
$query3 =mysql_query("select * from staff_bankinfo where staff_code=".$_POST['staff']);
$row1 = mysql_fetch_array($query3);
}
else if(isset($_POST['contact']))
{
mysql_query("INSERT into staff_bankinfo (staff_code, bank_name,branch,ifsc,acno) values('$_POST[staf]', '$_POST[bank_name]','$_POST[branch]','$_POST[ifsc]','$_POST[acno]')") or die(mysql_error());
$msg= "Added";
}
else
{
if ( isset($_POST['download']) && !empty($_POST['download']) ) {
$staff_id = $_POST['staff_id'];
if ($staff_id) {
header('Location: report1.php?num='.$staff_id);
}
}
}
