Question

我想将产品详细信息插入到数据库中，但它不会被添加到数据库中，我也会收到此错误

“注意：会话已经启动 - 忽略session_start（）在C：\ xampp \ htdocs \ regal \ admin \ insert_products.php第2行“

<?php
session_start();
echo "WELCOME:  "."<b>". $_SESSION['user']."</br>";
  if(!isset($_SESSION['ISLOGIN'])){
      echo "<script>window.open('login.php?log=NOT AN ADMIN!!','_self')</script>";
      die;
  }
  else{

使用脚本顶部的session_start（）;

检查会话是否正在运行

If(session_status() === PHP_SESSION_DISABLED || PHP_SESSION_NONE ) {
    session_start();
}

如果它仍然存在。说明db.php发布的错误

这是我将数据插入数据库的代码...但它不会插入到数据库中
