from表单提交数据库

我遇到了from表单无法提交至数据库的问题

```html
        <from method="post" action="tijiao.php">
        <input type="text" placeholder="在此述说" class="van-field__control" name="name"/>
        <input type="submit" value="提交至数据库"/>
    from>

在点击submit后程序无任何相应

在出现错误后我将inpu标签改为textarea再次尝试依旧无法解决

以下是php代码

```php

$conn=mysqli_connect('localhost','uersname,'password','        ');
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "连接成功";
mysqli_query($connect, "ste names 'utf8'");
$name = $_POST['name'];

$sql = "INSERT INTO newyear2023 (id, neirong) VALUES (NULL, '$name')";

mysqli_close($conn);
?>

```

form表单。不是from而是form标签，你好像写错了
