我只是在此SQL查询中找不到语法错误

Question

您能告诉我此查询出了什么问题吗？我只是找不到错误，这使我发疯。

<?php
$query = "INSERT INTO atable (fortlaufend, vorname, nachname, land, email, caption1, caption2, caption3, caption4, caption5, datum) 
VALUES (NULL, 
" . mysql_real_escape_string($_POST[vorname]) . ", 
" . mysql_real_escape_string($_POST[nachname]) . ", 
" . mysql_real_escape_string($_POST[land]) . ", 
" . mysql_real_escape_string($_POST[email]) . ", 
" . mysql_real_escape_string($_POST[caption1]) . ", 
" . mysql_real_escape_string($_POST[caption2]) . ", 
" . mysql_real_escape_string($_POST[caption3]) . ", 
" . mysql_real_escape_string($_POST[caption4]) . ", 
" . mysql_real_escape_string($_POST[caption5]) . ", 
CURRENT_TIMESTAMP)";
?>

“ fortlaufend”是AUTO_INCREMENT的主要索引。mysql_error是

查询无效：您的SQL语法有误；检查与您的MySQL服务器版本相对应的手册以获取正确的语法，以在“名称，姓氏，国家/地区，电子邮件”附近使用，这使这张照片对您特别吗？，第3行

谢谢！

对于非整数值，您需要单引号。

  <?php
    $query = "INSERT INTO atable (fortlaufend, vorname, nachname, land, email, caption1, caption2, caption3, caption4, caption5, datum) 
    VALUES (NULL, 
    '" . mysql_real_escape_string($_POST[vorname]) . "', 
    '" . mysql_real_escape_string($_POST[nachname]) . "', 
    '" . mysql_real_escape_string($_POST[land]) . "', 
    '" . mysql_real_escape_string($_POST[email]) . "', 
    '" . mysql_real_escape_string($_POST[caption1]) . "', 
    '" . mysql_real_escape_string($_POST[caption2]) . "', 
    '" . mysql_real_escape_string($_POST[caption3]) . "', 
    '" . mysql_real_escape_string($_POST[caption4]) . "', 
    '" . mysql_real_escape_string($_POST[caption5]) . "', 
    CURRENT_TIMESTAMP)";
    ?>
