我正在尝试向我的mysql数据库发送一个值，我对php/bootstrap编程非常陌生，我已经尝试了所有的方法，但是大多数指南都超出了我的理解范围。请引导我在正确的路径上，这样在按钮点击按钮将更新特定的数据库。
下面是按钮单击将要做的：在卸载按钮单击它将发送更新数据库，如
update activate=“no”from software where uid（or id）=“单击按钮的行的相同id”[我知道这个mysql查询是错误的]
这是我的密码：

如果您希望它立即发生，那么使用ajax将请求发送到php服务器，请参阅https://www.w3schools.com/php/php_ajax_database.asp 更多信息。
如果你想它与重定向然后使用

$conn = new mysqli("DBservername", "DBusername", "DBpassword", "DBname");
if ($conn->connect_errno) {
    $errormsg = ("Database Connection failed: " . $conn->connect_error );
    return $errormsg;
}
$res=mysqli_query($conn, "SELECT * FROM 'table' WHERE 'something'");
$row=$res->fetch_array();
$count = mysqli_num_rows($res); // if fetch correct it returns must be 1 row
mysqli_close($conn);
if( $count == 1 ) etc

发送查询、更新、删除等。

$sql = "DELETE FROM 'table' WHERE 'something';
mysqli_query($conn,$sql);

粗糙和糟糕的php代码，但应该工作。
在我理解了您的实际要求之后进行编辑：当呈现来自数据库的结果时，锚定每个按钮以重定向到页面/update/{rowid}或/update.php？id={rowid}
并在该链接中使用条件等执行查询。

您可以通过此代码向服务器发送请求。

$con = new mysqli_connect("servername", "username", "password", "name");
    if(!$con)
    {
       die("DB CONNECTION ERROR");

    }
    $result=mysqli_query($con, "SELECT * FROM 'table' WHERE 'something'");
    $row=$result->fetch_array();
    $count = mysqli_num_rows($result); 
    mysqli_close($con);
    if( $count == 1 )
