Question

我想显示用户插入的数据，以保存到数据库中的2个表中。但是这段代码对我不起作用。

  $query = "INSERT INTO partnumber (Partnumber, Description, Min, Max) VALUES
        ('" . $_POST ["part"] . "', '" . $_POST["description"] . "', '" . $_POST["min"] . "', '" . ($_POST["max"]) . "')INSERT INTO forecast (Partnumber, Min, Max) VALUES 
        ('". $_POST ["part"] . "', '" . $_POST["min"] . "','" . ($_POST["max"]) . "')";

    $result = $db_handle->insertQuery($query);
    if(!empty($result)) {
        $error_message = "";
        $success_message = "Saved successfully!";   
        unset($_POST);
    } else {
        $error_message = "Problem in saving. Try Again!";   
    }

    $sql = "INSERT INTO forecast (Partnumber, Min, Max) VALUES 
    ('". $_POST ["part"] . "', '" . $_POST["min"] . "','" . ($_POST["max"]) . "')";

    $result = $db_handle->insertQuery($sql);
    if(!empty($result)) {
        $error_message = "";
        $success_message = "Saved successfully!";
    } else {
        $error_message = "Problem in saving. Try again!";
    }

错误是

无效查询

有人可以帮忙吗？

Your first two queries are separated by anything and it is not understood by SQL. You can use multi queries. Here is an example: bool mysqli_multi_query ( mysqli $link , string $query ). You can read more about it here.
