Question

如何在表单提交时设置cookie？

这是我在使用cookie后即可使用的代码。

<?php
if(isset($_COOKIE['v_regUsr']))
{
header("Location: dont-show-pop-up-with-form.php");
}
else
{
header("Location: show-pop-up-form.php");
}
?>

但是我需要在提交表单时使用'v_regUsr'的名称或值设置cookie。

因此用户访问该网站。页面检查cookie是否存在...如果是，那么它不会显示弹出窗口。如果cookie不在那里，那么它应该显示一个带有“form”的弹出窗口

一旦表单上的点击提交，就会放置cookie“v_regUsr”并且他们不会再看到弹出窗口。

任何人都可以帮助我吗？感谢

Answer 1

setcookie("v_regUsr", "value");

您还可以为Cookie添加有效的持续时间：

setcookie("v_regUsr", "value", time()+3600*24*365);  // 1 year.

Answer 2

在javascript中：

 document.cookie="v_regUsr=" + cookievalue;

参考：http://www.tutorialspoint.com/javascript/javascript_cookies.htm

如果您想使用php设置Cookie，请使用 setcookie() 功能

$value = 'Your Values';
setcookie("v_regUsr", $value, time()+3600);  /* expire in 1 hour */

<强>更新

 $(document).ready(function() {      
   $("#theForm").validate({
       submitHandler: function(form) {
       // do other things for a valid form
             var cookievalue="your value";
             document.cookie="v_regUsr=" + cookievalue;
             form.submit();
          }
      });
});

当表单从PHP提交时如何设置cookie？
