我正在使用3个提交按钮：
-第一个按钮，用于根据下拉列表搜索值
-第二个按钮，仅更新值
-第三个按钮，用于下载pdf文件。
我的表格应该是
<?php
include("config/config.php");
include("header.php");
?>
<?php
if (!empty($_POST['mailing-submit'])) {
Query1;
query2;
query3;
} else if (!empty($_POST['contact-submit'])) {
update query;
} else {
$sheet_no = 202565;
header('Location: print_details.php?num='.$sheet_no);
}
?>

那些提交按钮不起作用。我在编码中犯了什么错误。当我更改为关闭标签时，将不会显示任何输出。如何纠正错误？
答案 0 :(得分：0)
您的提交按钮不起作用，因为您在按钮之前关闭了表单。
像这样更改代码：
<?php
include("config/config.php");
include("header.php");
?>
<?php
if (!empty($_POST['mailing-submit'])) {
Query1;
query2;
query3;
}
else if (!empty($_POST['contact-submit'])) {
{
update query;
}
else {
$sheet_no = 202565;
header('Location: print_details.php?num='.$sheet_no);
}
?>
