我需要帮助，我的代码不起作用，它不会插入到表 db 中。我认为我的代码写得不好。我需要处理的部分是第一个开关案例！
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();

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, $partner_country";
应该看起来更像这样：
INSERT INTO poslovni_partneri(Partner_name,Partner_street, Partner_zip, Partner_city, Partner_country)
VALUES('$partner_name','$partner_street','$partner_zip', '$partner_city', '$partner_country')";
您还应该与引号保持一致，有时在变量周围使用它，有时不使用它。
此外，你甚至不应该以这种方式查询;你应该使用预准备语句，因为这样你就可以为SQL注入打开。
编辑
您说您需要 PDO，您正在建立 PDO 连接，但您正在使用mysql_*特定函数进行查询，这不是您应该使用 PDO 的方式，与 PDO 无关。
编辑 2
您还应该验证帖子参数是否实际可用，对帖子参数执行类似操作：
$partner_name = isset($_POST['partner_name']) ? $_POST['partner_name'] : '';
（注意小写的p）
使用三元运算符，并对所有 post 参数执行此操作，如果您的任何参数是空字符串，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）与您尝试在 post 参数中匹配的属性标识符不匹配。
