使用表单 POST 后如何将变量存储在会话中？

Question

这可能吗？我已经使用表单 post 发送了一个值并在 php 中检索但是如果我刷新它就会消失。可以存储吗？

Answer 1

是的，您可以将其存储在 SESSION 中。请阅读以下代码：-

<?php
// Start the session
session_start();
?>
<!DOCTYPE html>
<html>
<body>

<?php
// Check Post variables are available
if(isset($_POST['username']))
{
    echo $_POST['username']." Username found in form <br />";
    // Set session variables
    $_SESSION["username"] = $_POST['username'];
    echo $_SESSION["username"]." stored in session <br />";;
}
else
    echo 'No, form submitted. Your old stored username was '.$_SESSION["username"];
    //echo 'No, form submitted.';
?>

</body>
</html>

开始会话

在您的 functions.php

中写入以下代码

function register_my_session()
{
    if( !session_id() )
    {
        session_start();
    }
}

add_action('init', 'register_my_session');

Answer 2

// set session to start
/*session is started if you don't write this line can't use $_Session  global variable*/
session_start();


$_SESSION["newsession"]= $value;
$_SESSION['post_session'] = $_POST;

你可以看到session的文档 http://php.net/manual/en/reserved.variables.session.php
