【问题描述】：
我有这个表格可以将数据输入 MySQL 数据库。它没有给我任何错误，也没有插入数据。我浏览了网络，但无济于事。我不确定这是我的代码还是我的数据库配置错误。这是所有代码。

这里是 PHP
<?php
$dateSurvey = $_POST["dateSurvey"];
$plantName = $_POST["plantName"];
$plantLoc = $_POST["plantLoc"];
$plantContact = $_POST["plantContact"];
$direction = $_POST["direction"];

$flrLevel = $_POST["flrLevel"];
$elevation = $_POST["elevation"];
$tagNumb = $_POST["tagNum"];
$mmn = $_POST["mmn"];
$size = $_POST["size"];
$pressure = $_POST["pressure"];
$service = $_POST["service"];
$trapCond = $_POST["trapCond"];
$sql_connection = mysql_connect("localhost", "******", "******");
mysql_select_db("******", $sql_connection) or die( "Unable to select database");
$sql = "INSERT INTO steamtraps (
dateSurvey,
plantName,
plantLoc,
plantContact,

location,
flrLevel,

trapCond,

)
VALUES (
'{$dateSurvey}',

NOW()

mysql_query($sql, $sql_connection);
mysql_close($sql_connection);
?>
【问题讨论】：
-
你检查你的数据库连接了吗？
-
我在查询的最后一列之后看到一个额外的逗号
-
您是否验证了整个查询？换句话说，如果你在
mysql_query之前print $sql;，你会看到什么 -
@RonakPatel 我的服务器上有另一个文件用于检查连接性。但是，
mysql_select_db("******", $sql_connection) or die( "Unable to select database");会检查它，除非有更好的方法。 -
Please, don't use
mysql_*functions in new code。它们不再维护and are officially deprecated。看到red box？改为了解prepared statements，并使用PDO 或MySQLi - this article 将帮助您决定哪个。如果你选择 PDO，here is a good tutorial.
