我要疯了，试图学习如何使用会话来存储自定义字段的值在我的registration_form.php，所以我可以调用其他页面上的数据。我读过各种各样的网站，但似乎没有人解释我到底应该把代码捕获的数据。我有两个自定义注册字段，我添加到一个脚本(生物和displayname)。我尝试在注册表单的顶部和底部以及register.php(下面的两个脚本)上插入此代码。
将这些字段存储到会话的代码在哪里?我知道这是错误的，因为在这一点上，我已经试着把它放在任何地方，我可以....
//registration_form.php<?php session_start();
$_SESSION['displayname'] = $displayname;
$_SESSION['bio'] = $bio;
$author = $_SESSION['displayname'];
$bio = $_SESSION['bio'];
?>

我不确定你在这里想要什么，但不应该在regiisration_form .php中的表单动作设置为register.php?
<form class="form-horizontal" id="register_form" method="post" action="register.php">
然后您的表单将被提交到register.php。您在register.php中设置Session的方式基本上是正确的。要访问其他页面中的会话值，执行以下命令:
$displayname= $_SESSION['displayname'];
$bio=$_SESSION['bio'];
