在 mysql/php 中插入错误 - Insert error in mysql/php

Insert error in mysql/php

本文关键字：插入错误 php mysql | 更新日期: 2023-09-27

我有这个功能：

   public static function insert_user($user)
{
    $con = mysql_connect("localhost","root","") or die(mysql_error());
    mysql_select_db("speakom",$con) or die(mysql_error());
    mysql_query("INSERT INTO user (user_ip,user_name,full_name,email_address,password,gender,birthday,banned,role,country) 
        VALUES('".$user->ip."','".$user->name."','".$user->full_name."','".$user->email."','".$user->password."',".$user->gender.",'".$user->birthday."',".$user->banned.",".$user->role.",'".$user->country."'") or die(mysql_error());
    mysql_close($con);
}

我收到此错误：

您的 SQL 语法有误;请查看与您的 MySQL 服务器版本对应的手册，了解在第 2 行的 '' 附近使用的正确语法

错误指向何处？我如何知道错误在哪里？

您缺少VALUES (子句的结束)。通常，在将变量传递给 mysql_query 之前，将 SQL 分配给变量（您可以输出该变量以进行调试）会更容易。

与其大喊大叫，不如使用 PDO 和准备好的语句，以下是 PDO 风格的答案：

$con = new PDO('mysql:host=localhost;dbname=speakom', 'root', ''); // optionally add encoding options
$con->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // enable exception throwing
$stmt = $db->prepare('INSERT INTO user (user_ip, user_name, full_name, email_address, password, gender, birthday, banned, role, country) 
    VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)');
$stmt->execute(array(
    $user->ip, $user->name, $user->full_name, $user->email, $user->password, 
    $user->gender, $user->birthday, $user->banned, $user->role, $user->country,
));

免责声明没有对此进行测试，但它应该给你一个好主意:)

你会运行

吗

echo "INSERT INTO user (user_ip,user_name,full_name,email_address,password,gender,birthday,banned,role,country)      VALUES('".$user->ip."','".$user->name."','".$user->full_name."','".$user->email."','".$user->password."',".$user->gender.",'".$user->birthday."',".$user->banned.",".$user->role.",'".$user->country."'";

我建议您使用"用户"而不是user

VALUES('".$user->ip."','".$user->name."','".$user->full_name."','".$user->email."','".$user->password."',".$user->gender.",'".$user->birthday."',".$user->banned.",".$user->role.",'".$user->country."'"

你最后错过了)。顺便说一下，使用 PDO 或 mysqli。

您要插入的某些值不在引号中，并且您错过了VALUES的结束)。试试这个

mysql_query("INSERT INTO user (user_ip,user_name,full_name,email_address,password,gender,birthday,banned,role,country) 
    VALUES('$user->ip', '$user->name','$user->full_name', '$user->email', '$user->password', '$user->gender', '$user->birthday', '$user->banned', '$user->role', '$user->country')") or die(mysql_error());
