我是php的新手，我试图在我的html表单和数据库之间创建一个链接，但它不起作用。请帮助我。谢谢我在同一页面上有html标签和php代码，我已经正确安装了mysql并创建了我的数据库，但它仍然是链接。

好吧，就像评论中提到的那些人一样;什么是不起作用？我还建议您使用mySQLi而不是mySQL。

关于如何制作插入表格的表单的示例;

<form action='index.php?a=register' method='post'> <!-- You can use if(isset($_POST['submit'])) as well, but I prefer ?a(ction)= :) -->
Username: <input type='text' name='username /> Password: <input type='password' name='password' />
<input type='submit' value='Register' />
</form>

<?php
$db = mysqli_connect("server_name", "user", "password", "database") or die (mysqli_error());
if($_GET['a']=='register')
{
$username = $_REQUEST['username']; // Can also use $_POST
$password = md5($_REQUEST['password']); // Same here ^.
mysqli_query($db, "INSERT INTO users(username, password) VALUES('$username', '$password')");
}
?>

如果您仍想使用mysql，只需将“mysqli”更改为“mysql”，然后编辑连接以及查询。我会用你的代码来帮助你，但是你没有真正指出什么是错的我会简单地给你这个例子。 :) 正如其他人也说的那样;你应该熟悉如何防止SQL注入。
