我的PHP变量没有插入我的MySQL表
[英]My PHP variables aren't inserting into my MySQL table
问题描述
<?php
mysql_connect("10.246.16.129", "alanay_org", "SNIP")or die("Cannot Connect");
mysql_select_db("alanay_org")or die("cannot select DB");
INSERT INTO members ('id', 'username', 'password')
VALUES
(NULL, '$_POST[username]','$_POST[password]')";
?>
My code isn't inserting into my MySQL table, the rows go by id, username then password. 
我的代码没有插入我的MySQL表，行按id，用户名和密码。 I've checked and I haven't gotten anything wrong from the HTML register form. 我已经检查过，我没有从HTML注册表单中得到任何错误。 Please help. 请帮忙。
Sorry, I'm really new to PHP. 对不起，我是PHP新手。 Give me a break. 给我一个休息时间。
EDIT: 编辑：
This is the register.php 这是register.php
<!DOCTYPE html>
<html>
<head>
<title>Login</title>
<link rel="stylesheet" type="text/css" href="/form/stylesheet.css" />
</head>
<body>
<center>
<form action="/form/registered.php" method="post">
<input class="username" name="username" type="text" placeholder="Username" />
<input class="password" name="password" type="password" placeholder="Password" />
<input class="submit" type="submit" value="Register" />
</form>
</center>
</body>
</html>
This is the registered.php 这是registered.php
<?php
$con = mysqli_connect("10.246.16.129","alanay_org","password","alanay_org");
$sql = "INSERT INTO members ('username', 'password') VALUES ('$_POST['username']','$_POST['password']')";
mysqli_query($con, $sql);
?>
What am I doing wrong? 我究竟做错了什么？ :( :(

Your post variables have the wrong syntax. 您的帖子变量的语法错误。 This: 这个：
$_POST[username]
should be: 应该：
$_POST['username']
Plus what @Dagon said. 再加上@Dagon说的话。

Here is how to do it: 这是怎么做的：
$con=mysqli_connect("host","username","password","database_name");
mysqli_query($con,"INSERT INTO members ('username', 'password') VALUES ($_POST['username'], $_POST['password']);
You don't need to put id if it is auto-increment. 如果是自动增量，则不需要输入id。
This method is not secure from SQL injections. SQL方法不能保证此方法的安全性。 You can use prepared statements for security purposes. 出于安全目的，您可以使用预准备语句。

<?php
mysql_connect("10.246.16.129", "alanay_org", "SNIP")or die("Cannot Connect");
mysql_select_db("alanay_org")or die("cannot select DB");
mysql_query("INSERT INTO members ('username', 'password') VALUES ('".$_POST['username']."','".$_POST['password']."')");
?>
If this doesn't work for you, your POST-variables are missing or empty. 如果这对您不起作用，则POST变量将丢失或为空。
