我正在学习用Php编程。 我有一个索引页面html，它具有链接到connection.php页面的动态形式，在该页面中我已经完成了与数据库的连接，并且在其中我创建了一个查询以将数据插入数据库中（这是我进行的正确方式吗？）
我想给你看代码：
index.html

我的问题是关于插入数据库，因为我写的查询不正确。 我的数据库有2个表：
Prenotazione： 诺姆 认知度 日期 电子邮件 节 oggetto
个人服务： nome_p cognome_p email_p olo email_richiedente oggetto_richiedente
您认为谁可以编写查询以从动态表单中插入数据？
非常感谢您的帮助！

代码对我来说似乎很正确，除了一件事。插入SQL查询。可以通过$ _GET []或$ _POST []数组和'name'属性作为键来访问PHP中的表单值。由于您在表单中使用POST方法，因此请使用$ _POST []。我在这里给你一个例子，让你有个主意：
HTML：
<form action="insert.php" method="POST">
<input type="text" name="name"/><label>Name</label>
<input type="text" name="age"/><label>Age</label>
<input type="text name="submit" value="Submit"/>
</form>
PHP：
/*Now here is the part where you should change your code based on this example
As you notice we used $_POST['submit'], $_POST['name'] and $_POST['age'] because as I have said we get their values by their name attribute.
PHP works this way.
*/
/* Use isset to check if the form datas are there. Often without the isset, you'll get an undefined index error. */
if(isset($_POST['submit'])) {
/* Declare POST form datas into variables just for a better code format */
$name = $_POST['name'];
$age = $_POST['age'];
$query = "INSERT INTO users(name, age) VALUES($name, $age)";
$query_run = mysqli_query($query);
}

实际上，您必须阅读Retrieve post array values，这是因为在index.html中有一些未“正确”命名的输入标签。这可能导致混乱。输入标记中的诸如“ arr []”之类的名称大部分时间用于组织帖子中的数组，并允许它们像$ _POST ['arr']这样在php端进行访问。我不确定$ _POST ['arr []']会返回给您什么，但似乎没有什么用。在您发送的示例中，似乎您需要遍历每个$ _POST子数组以构建用于插入的sql。例如：
<html>
<body>
<?php
print_r($_POST);
?>
<form name="form1" method="POST">
<input type="text" name="name1" />
<input type="text" name="name2" />
<input type="submit" />
</form>
<form name="form2" method="POST">
<input type="text" name="name[1]" />
<input type="text" name="name[2]" />
<input type="submit" />
</form>
<form name="form3" method="POST">
<input type="text" name="name[]" />
<input type="text" name="name[]" />
<input type="submit" />
</form>
</body>
</html>
如果使用a和b作为表单输入值，将导致以下输出
Array ( [name1] => a [name2] => b )
第一种形式，
Array ( [name] => Array ( [1] => a [2] => b ) )
第二种形式，
Array ( [name] => Array ( [0] => a [1] => b ) )
对于第三种形式（“名称”数组会自动索引）
希望有帮助
