php - 我想在 php mysql 中添加两个文本框的数值

Question

我想添加两个文本框的值并将两个文本框的值存储起来，使用 php 将其求和到 mysql 数据库表中，如下代码

        <?php
    //Include Database
    include 'db.php';
    $data = new Databases;
    $msg = '';
    if(isset($_POST["submit"]))
    {
     $insert_data = array(
     'first' => mysqli_real_escape_string($data->con, $_POST['first']),
     'Second' => mysqli_real_escape_string($data->con, $_POST['Second']),
     );
     if($data->insert('sum', $insert_data))
     {
     $msg = "Inserted Data Successfully!";
     }
    }
    ?>

    <?php
    if(isset($msg))
    {
     echo $msg;
    }
    ?>

尝试这个而不是数组。

  $sum = $_POST['first'] + $_POST['Second'];
  if($data->insert('sum',$sum)){
   $msg = "Inserted Data Successfully!";
  }else{
   $msg = "Inserted Data Successfully!";
  }
