我已经在这工作了几个小时,似乎无法让这几行代码工作。这是我第一次使用MySQL,所以请耐心等待。
<?php
$con = mysql_connect("localhost","usernamewitheld","passwordwithheld");
if (!$con){die('Could not connect: ' . mysql_error());}
mysql_select_db("splashpage");
mysql_query("INSERT INTO 'email' ('emailaddress') VALUES ('$_POST[email]');", $con);
mysql_close($con);
?>
代码执行没有来自apache的任何错误,但数据库保持不受影响。有什么想法吗?
编辑:表格结构如下:
Field Type Null Key Default Extra
emailaddress text NO MUL NULL
timesubmitted timestamp NO CURRENT_TIMESTAMP

删除半冒号,在查询中使用bacticks而不是单引号。
mysql_query("INSERT INTO `email` (`emailaddress`) VALUES ('$_POST[email]')", $con)
or
die(mysql_error());
注意: Please, don't use mysql_*
functions in new code。它们不再被维护and are officially deprecated。请参阅red box?转而了解prepared statements,并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。

在列名称`
'
mysql_query("INSERT INTO 'email' ('emailaddress') VALUES ('$_POST[email]');", $con);
应该是
mysql_query("INSERT INTO `email` (`emailaddress`) VALUES ('$_POST[email]')", $con);

使用此功能。
<?php
mysql_query("INSERT INTO email (emailaddress) VALUES ('".$_POST[email]."')", $con);
mysql_close($con);
?>

尝试
<?php
$con = mysql_connect("localhost","usernamewitheld","passwordwithheld");
if (!$con){die('Could not connect: ' . mysql_error());}
mysql_select_db("splashpage",$con);
mysql_query("INSERT INTO 'email' ('emailaddress') VALUES ('$_POST[email]');", $con);
echo mysql_errno($con) . ": " . mysql_error($con) . "\n";
mysql_close($con);
?>
