如何获得不同的按钮来提交不同的mySQL查询

Question

我正在尝试在HTML表单中创建一个按钮，在相应的mySQL位置添加一个数字。基本上，一个帖子的投票选项。现在，按钮都做同样的事情：他们从底部提交原始帖子查询。我如何让他们单独行动？

PHP：                                                               
                        

                    if (!$thepipeline) {
                        echo "Error: Unable to connect to MySQL." . PHP_EOL;
                        echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
                        echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
                        exit;
                    }
                    if (!empty ($_POST)) { 
                        $squery = "INSERT INTO votes (votes) VALUE (1)";
                        print $squery;                                                      
                        $votes_result = mysqli_query ($thepipeline, $squery);
                    }
                    $query = "SELECT p.post_id, p.member_id, p.content, p.date_created,
