Question

我正在尝试将表单输入到数据库中，但是显示两个不同的错误

"Error: INSERT INTO movie (firstname, surname, phonenumber, email, movie, session, day) values(jon, doe, johndoe@icloud.com, 123456789, halloween, afternoon, tuesday)You have an error in your SQL syntax;
 check the manual that corresponds to your MariaDB server version for the right syntax to use near '@icloud.com, 123456789, halloween, afternoon, tuesday)' at line 3"

我尝试删除“ @”符号，但出现了这种情况：

"Error: INSERT INTO movie (firstname, surname, phonenumber, email, 
movie, session, day) values(jon, doe, johndoeicloud.com, 123456789, 
halloween, afternoon, tuesday)Unknown column 'jon' in 'field list'"

这是我的代码

if (!empty($firstname) || !empty($surname) || !empty($email) || !empty($phonenumber) || !empty($Localmovie) || !empty($session) || !empty($day)) {
        $host = "localhost";
        $dbUsername= "root";
        $dbPassword="";
        $dbName="tickets";

        //create connection
        $conn= new mysqli($host, $dbUsername, $dbPassword, $dbName);

        if (mysqli_connect_error()) {
        die('Connect 
Error('.mysqli_connect_errno().')'.mysqli_connect_error());
    }else{


             //$sql = "INSERT INTO tutorials_inf(name)VALUES ('".$_POST["name"]."')";
            $sql= "INSERT INTO movie
                        (firstname, surname, phonenumber, email, movie, session, day) 
                   values($firstname, $surname, $email, 
$phonenumber, $Localmovie, $session, $day)";
            if (mysqli_query($conn, $sql)) {
               echo "New record created successfully";
            } else {
               echo "Error: " . $sql . "" . mysqli_error($conn);
            }
            $conn->close();

在您的值中添加单引号以表示字符串，并根据您的列正确重新排列值（您错位了phonenumber和email列值序列）

$sql= "INSERT INTO movie (firstname, surname, phonenumber, email, movie, session, day) values($firstname, $surname, $email, $phonenumber, $Localmovie, $session, $day)";

收件人

$sql= "INSERT INTO movie (firstname, surname, phonenumber, email, movie, session, day) values('$firstname', '$surname', '$phonenumber', '$email','$Localmovie', '$session', '$day')";

日期和字符串值应放在单引号中。
数字值不需要用引号引起来。

怎么了？ “错误：INSERT INTO...。'字段列表'中的未知列'jon'”
