错误

Error: INSERT INTO release (id, producers, company, title) VALUES ('null', 'lol', 'lol', 'lol') 
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'release (id, producers, company, title) VALUES ('null', 'lol', 'lol', 'lol')' at line 1

解决：是为增加蜱release

什么错误的表现？ – JYoThI

也添加mysql错误，你看到 –

释放一个MySQL keyword简单，并应在反引号括起来：'release`

它应该在评论区 – JYoThI

哦shiet，感谢这.... – Jordan

在我看来，这id不应该被分配字符串值'null'。通常id列自动递增，在这种情况下，你应该简单地忽略列：

$sql = "INSERT INTO `release` (producers, company, title) 
VALUES ('".addslashes($producers)."', '".addslashes($company)."', '".addslashes($title)."'";

的addslashes是保护再次SQL injection。你还应该净化你的输入：

$producers = strval($_POST['producers']); 
$company = strval($_POST['company']); 
$title = strval($_POST['title']);

尝试使用表名反引号，如果它是关键字release

$sql = "INSERT INTO `release` (id, producers, company, title) 
      VALUES ('null', '$producers', '$company', '$title')";

而且最好是写你的数据库的格式如下数据库名称 - >db_name例如db_release和表名称 - >tb_name例如tb_release

以免关键字错误

我个人更喜欢简单的未装饰的名称，以减少我的代码中的混乱。 –

yaah它不是很糟糕，但我建议你先用db_或tb_ –
