Question

我收到此错误：

错误：INSERT INTO用户（用户名，密码，邮件，余额， depost1，depost2，depost3）VALUES（测试， 4f4dfc9a3bec784d456fafabc725977e，test @ test.test，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;）您的SQL语法有错误;检查手册对应于您的MariaDB服务器版本，以获得正确的语法靠近＆＃39; @ test.test，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;，＆＃39; 0＆＃39;）＆＃39;在2号线。

所以，我查看了我的语法，但我找不到任何错误的东西。这是我的代码：

<?php
inculde('config.php');
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
$sql = "INSERT INTO users (username, password, mail, balance, depost1, depost2, depost3)
VALUES ($user, $result, $mail, '0', '0', '0', '0')";
if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>

Answer 1

您错过了查询中的引号

<?php
    inculde('config.php');
    $conn = new mysqli($servername, $username, $password, $dbname);
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 
    $sql = "INSERT INTO users (username, password, mail, balance, depost1, depost2, depost3)
    VALUES ('$user','$result', '$mail', '0', '0', '0', '0')";
    if ($conn->query($sql) === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
    $conn->close();
?>

Answer 2

在查询中使用值中的单引号

$sql = "INSERT INTO users (username, password, mail, balance, depost1, depost2, depost3) VALUES ('$user', '$result', '$mail', '0', '0', '0', '0')"

Answer 3

将变量直接放在字符串中时，它们不会自动用引号括起来，即使它们是字符串。

您必须将查询更改为以下内容：

$sql = "INSERT INTO users (username, password, mail, balance, depost1, depost2, depost3) VALUES ('$user', '$result', '$mail', '0', '0', '0', '0')";
