PHP表单处理和验证不起作用
我的表单有下面的代码，它似乎不起作用，在填写完所有字段后查询不会插入。如果有人能看一下，帮我改正错误，我会非常感激的。表单的方法是post，操作是PHP表单处理和验证不起作用,php,forms,validation,processing,Php,Forms,Validation,Processing,我的表单有下面的代码，它似乎不起作用，在填写完所有字段后查询不会插入。如果有人能看一下，帮我改正错误，我会非常感激的。表单的方法是post，操作是。这是我在PHP中的第一个代码，非常新，谢谢 <?php $counter=1; if (isset($_POST["post"])) { $gender= $_POST['gender']; $fname= $_POST['fname']; $lname= $_POST['lname']; $email=

请显示表格代码，并在表格处理结果中具体说明。到底是什么不起作用
同时，以下是一些观察结果：
您可以执行以下操作，而不是一次分配每个$\u POST
元素：
foreach（$\发布为$key=>$value）$$key=$value
*$output\u form*
和*$is\u error*
始终具有相同的值，为什么重复
您的“$query=“INSERT INTO'elect_conference”…”代码严重混乱…在编写问题时可能会出现一些明显的错误；例如，$query
字符串定义中有一些值在分号（，$other'）；”之后重复电子邮件“，”学校“
等）；您的标签
是用
标签“关闭”的，您有在这里输入代码
在不同的地方。。。请尽你所能解决问题，并详细告诉我们哪些不适合你（而不仅仅是“它不适合你”）。你的yourdoingforeach（$\u POST as$key=>$value）$$key=$value可能很危险。如果将其添加到当前代码中，我可以在页面上定制帖子，并以alert（“您被劫持”）的形式传递计数器，javascript将在页面上运行。这就是所谓的跨站点脚本，这是一个禁忌
