更改此项:

1 mysqli_real_escape_字符串需要2个必需参数

2$Firstname和$Lastname是字符串变量。在查询中使用时,它们应该用单引号括起来

$FirstName = mysqli_real_escape_string($con, $_POST["FirstName"]);
$LastName = mysqli_real_escape_string($con, $_POST["LastName"]);
$Age = mysqli_real_escape_string($con, $_POST['Age']);

$sql="INSERT INTO Persons (Name, LastName, Age);
      VALUES ('$FirstName', '$LastName', $Age)";
卡恩奇:

  // escape variables for security
        $FirstName = mysqli_real_escape_string($_POST["FirstName"]);
        $LastName = mysqli_real_escape_string($_POST["LastName"]);
        $Age = mysqli_real_escape_string($_POST['Age']);
致:

mysqli_real_escape_字符串需要传递两个参数 1连接

2替罪羊串

您只通过了escapestring,需要在mysqli\u real\u escape\u字符串中提供链接标识符

您还需要在查询内的字符串变量中添加引号。 更改:

致:


在PHP手册中查找mysqli_real_escape_字符串,并查看它期望的参数。这是非常基本的东西,所以呢?错误消息准确地告诉您出了什么问题。看一下手册,你就会知道如何修理它。我15岁了。这是我的借口。你的是什么?你刚刚评论并回复了我,我15岁了,感谢你不仅浪费了我的时间,还浪费了其他人的时间;检查与您的MySQL服务器版本相对应的手册,以了解使用near'的正确语法;第1行$Firstname和$Lastname处的值Andrew、Brin、15'是字符串变量。在查询中使用时,它们应该用单引号括起来。请尝试我的更新答案,并尝试了解您的脚本@user3553512I中出现了什么问题。现在出现了以下错误-错误:您的SQL语法有错误;检查与您的MySQL服务器版本相对应的手册,以了解使用near'的正确语法;第1行的值“FirstName”、“LastName”、“Age”
  // escape variables for security
        $FirstName = mysqli_real_escape_string($con,$_POST["FirstName"]);
        $LastName = mysqli_real_escape_string($con,,$_POST["LastName"]);
        $Age = mysqli_real_escape_string($con,$_POST['Age']);
$sql="INSERT INTO Persons (Name, LastName, Age);
            VALUES ($FirstName, $LastName, $Age)";
$sql="INSERT INTO Persons (Name, LastName, Age)
            VALUES ('$FirstName', '$LastName', '$Age')";
