我需要帮助，我的代码不能正常工作，它不会插入到表db中。我认为我的代码编写得不好。我需要工作的部分是第一个开关盒！
我需要它在pdo中，我的数据库和表数据是正确的。
<?php
if (isset($_GET['poslovni_korisnici'])) {
$active1 = 'class="active"';
}
else {
$active1 = '';
}
if(isset($_GET['korisnici'])) {
$active2 = 'class="active"';
}
else {
$active2 = '';
}
/*** mysql hostname ***/
$hostname = 'localhost';
/*** mysql username ***/
$username = 'root';
/*** mysql password ***/
$password = '';
try {
$dbh = new PDO("mysql:host=$hostname;dbname=zadatak1", $username, $password);
/*** echo a message saying we have connected ***/
/**echo 'Connected to database';**/
}
catch(PDOException $e)
{
echo $e->getMessage();
}

答案 0 :(得分：2)
您的SQL查询无效，因为它缺少右括号（)）;
INSERT INTO poslovni_partneri(Partner_name,Partner_street, Partner_zip, Partner_city, Partner_country)
VALUES('$partner_name','$partner_street',$partner_zip, $partner_city, $partner_country";
看起来应该更像这样：
INSERT INTO poslovni_partneri(Partner_name,Partner_street, Partner_zip, Partner_city, Partner_country)
VALUES('$partner_name','$partner_street','$partner_zip', '$partner_city', '$partner_country')";
你应该与引语保持一致，你有时会围绕变量使用它，有时候不会。但/ p>
此外，你甚至不应该这样查询;您应该使用prepared statements，因为这样您就可以SQL injections打开。
修改
您说您需要PDO，您正在建立PDO连接但是您使用mysql_*特定功能进行查询，这些功能不您应该如何使用PDO并与PDO无关。
修改2
您还应该验证帖子参数是否实际可用，使用您的帖子参数执行类似的操作：
$partner_name = isset($_POST['partner_name']) ? $_POST['partner_name'] : '';
（注意小写p ）
使用ternary operator，并对所有post参数执行此操作，如果任何参数为空字符串，则显示错误而不是查询。
编辑3
正如fred所指出的，partner_name！= Partner_name，即您的name属性标识符（在html中）与您尝试匹配的属性标识符不匹配在后论据中。
