Question

<?php

require('conn.php');

session_start();

ini_set('default_charset', 'UTF-8');

conopen();

mysql_query("SET NAMES utf8;");
$idedit = $_SESSION['id'] ;
$firstname = mysql_real_escape_string($_POST['firstnameedit']);
$lastname = mysql_real_escape_string($_POST['lastnameedit']);
$email = mysql_real_escape_string($_POST['emailedit']);
$username = mysql_real_escape_string($_POST['usernameedit']);
$password = mysql_real_escape_string($_POST['passwordedit']);


$query = " UPDATE `users` SET `firstname`= '" . $firstname . "',`lastname`='" . $lastname . "',`email`='" . $email . "',`username`='" . $username . "',`password`='" . $password . "', WHERE id = '" . $idedit . "'";
if (mysql_query($query) === true) {
   echo '<meta http-equiv="Refresh" content="0; URL=profile.php" />';
} 
else {
echo 'wrong';
}

conclose();
?>

我不知道为什么echo输出不正确。谁能告诉我什么是错的？我正在尝试重定向到profile.php。什么可能导致查询返回false？

Answer 1

在where子句之前有一个额外的逗号。

试试这个：

$query = " UPDATE `users` SET `firstname`= '" . $firstname . "',`lastname`='" . $lastname . "',`email`='" . $email . "',`username`='" . $username . "',`password`='" . $password . "' WHERE id = '" . $idedit . "'";

通常，您应该学会在变量替换后打印出查询，以查看真实查询的内容。执行此操作时，错误通常很明显。

Answer 2

我认为问题是查询中WHERE前面的逗号。

查询未执行，但没有错误
