整数的无效输入语法：“”

Question

我有一个问题，用 HTML 表单代码构建 INSERT PHP 文件。 当我从 HTML 表单中删除时，此错误会弹出“”整数的无效输入语法：“”第 2 行：“”

在所有代码中，我对每一行都进行了注释，没有任何注释。

有我的 PHP 脚本

`

$order_nr = pg_escape_string($_POST['order_nr']);
$date = pg_escape_string($_POST['date']);
$place = pg_escape_string($_POST['place']);
$service = pg_escape_string($_POST['service']);
$Vards = pg_escape_string($_POST['vards']);
$Uzvards = pg_escape_string($_POST['uzvards']);
$phone = pg_escape_string($_POST['phone']);
$email = pg_escape_string($_POST['email']);
$veids = pg_escape_string($_POST['veids']);
$passw = pg_escape_string($_POST['passw']);
$papildaprikojums = pg_escape_string($_POST['papildaprikojums']);
$save_info = pg_escape_string($_POST['save_info']);
$defekts = pg_escape_string($_POST['defekts']);

$query = " INSERT INTO serviss (order_nr, place, service, vards, uzvards, email, veids, passw, save_info, papildaprikojums, defekts)
                       VALUES ('$order_id', '$place', '$service', '$vards', '$uzvards', '$email', '$veids', '$passw', '$papildaprikojums', '$save_info', '$defekts') " ;
$result = pg_query($query);
if (!$result) {
    $errormessage = pg_last_error();
    echo "Error with query: " . $errormessage;
    exit();
}
printf ("These values were inserted into the database - %s %s %s", $order_id);
pg_close();

有我的 HTML 表单代码

我希望你能帮助我。

我使用 PostgreSQL 10.10

就像您将“order_id”与“order_nr”混为一谈。 名称值属性是“order_id”，因此当您尝试获取它时

$_POST['order_id'] not `$_POST['order_nr']`

这意味着要么你应该说

$order_nr = pg_escape_string($_POST['order_id']);

为了使用变量插入insert语句然后

$query = " INSERT INTO serviss (order_nr, place, service, vards, uzvards, email, veids, passw, save_info, papildaprikojums, defekts)
                   VALUES ('$order_nr', '$place', '$service', '$vards', '$uzvards', '$email', '$veids', '$passw', '$papildaprikojums', '$save_info', '$defekts') " ;

或者你应该说

$order_id = pg_escape_string($_POST['order_id']);

进而

$query = " INSERT INTO serviss (order_nr, place, service, vards, uzvards, email, veids, passw, save_info, papildaprikojums, defekts)
                   VALUES ('$order_id', '$place', '$service', '$vards', '$uzvards', '$email', '$veids', '$passw', '$papildaprikojums', '$save_info', '$defekts') " ;
