我也不太擅长php和英语。但是在这里，我将尝试让您了解我的问题我的问题是，当我在addproduct页面中将数据插入数据库而不设置会话时，它可以成功运行并且没有问题。但是当我设置会话并且user_status不是客户时，然后在同一页面中插入数据将无法正常工作，并将我发送到索引页面，我不知道为什么它将我重定向到该页面更新：当我尝试进入该页面时没有设置会话或我的状态是客户，则此条件成功运行以下是addproduct.php页面的一些代码
<?php //Condition for sessions
if(!isset($_SESSION['user_email']) || $_SESSION['user_status']=="customer") {
echo "session is not set";
}
else
{
//else it will stay in this page (means that session is set and user_status is not customer)

最佳答案
根据条件，在设置会话且会话为$ _SESSION ['user_status'] ==“ customer”时，它将重定向，您需要做的是根据情况更改条件
