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
<?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);
?>
```
