如何在 PHP 中使用准备好的语句在多个表中插入数据？

Question

我有两张表是billing_info, shipping_info。 billing_id 是主键，billing_id 是 shipping_info 中的外键。

我有 billing_info 地址表格。用户将填写账单信息，填写信息后有一个复选框，称为shipping address is different。如果任何用户选中该复选框，那么它将询问运输信息。根据数据填写运输信息后，billing info 将存储在 billing_info 表中，shipping_info 将存储在 shipping info 表中。

如果用户未选中该复选框，则只有帐单信息将存储在帐单信息表中。

<input type="checkbox" name="shipping_status" value="1">

如果用户未选中复选框但在选中复选框后无法插入数据，我只能将数据插入到 billing_info 的数据库中。 查询可能存在一些问题。我试过查询是

1)  START TRANSACTION;
    INSERT INTO table1 (column name)VALUES (values);
    INSERT INTO table2 (column name) VALUES (values);
    COMMIT;

 2) BEGIN;
    INSERT INTO table1 (column name)VALUES (values);
    INSERT INTO table2 (column name) VALUES (values);
    COMMIT; 

但仍然无法插入数据。 你愿意帮忙吗？

这是存储 int 用户信息的正确方法吗？

if (isset($_POST['submit'])){
  $b_firstname=$conn->real_escape_string(trim($_POST['b_firstname']));
  $b_lastname=$conn->real_escape_string(trim($_POST['b_lastname']));
  $b_address =$conn->real_escape_string(trim($_POST['b_address']));
  $b_country=$conn->real_escape_string(trim($_POST['b_country']));
  $b_state=$conn->real_escape_string(trim($_POST['b_state']));
  $b_city=$conn->real_escape_string(trim($_POST['b_city']));
  $b_pincode=$conn->real_escape_string(trim($_POST['b_pincode']));
  $b_mobileno=$conn->real_escape_string(trim($_POST['b_mobileno']));
  //$login_user_id=$conn->real_escape_string(trim($_POST['login_user_id']));
  //echo $shipping_status=$conn->real_escape_string(trim($_POST['shipping_status']));

  /*Shipping address*/
  $s_firstname=$conn->real_escape_string(trim($_POST['s_firstname']));
  $s_lastname=$conn->real_escape_string(trim($_POST['s_lastname']));
  $s_address =$conn->real_escape_string(trim($_POST['s_address']));
  $s_country=$conn->real_escape_string(trim($_POST['s_country']));
  $s_state=$conn->real_escape_string(trim($_POST['s_state']));
  $s_city=$conn->real_escape_string(trim($_POST['s_city']));
  $s_pincode=$conn->real_escape_string(trim($_POST['s_pincode']));
  $s_mobileno=$conn->real_escape_string(trim($_POST['s_mobileno']));

if (empty($conn->real_escape_string(trim($_POST['shipping_status'])))) {
  $shipping_status=0;
}
else{
$shipping_status=1;
}

if ($shipping_status==0) {

echo $sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)";
//  print_r($sql);
  $stmt = $conn->prepare($sql);
  $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added);

}
else{
  // prepare and bind
  echo $sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?);INSERT INTO shipping_info (s_firstname, s_lastname, s_address, s_country, s_state, s_city, s_pincode, s_mobileno,b_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?);";

  $stmt = $conn->prepare($sql);
  $stmt->bind_param("ssssssiiiisssssssiii", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added,$s_firstname, $s_lastname, $s_address, $s_country, $s_state, $s_city, $s_pincode, $s_mobileno,LAST_INSERT_ID());

}


  $stmt->execute();
  $stmt->close();

  }

//redirect code
//header('Location: contactus.php');
  $conn->close();
}

默认情况下，每次您要插入计费信息时，都不应在 if 语句中插入计费信息查询。

  $sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)";
        //  print_r($sql);
          $stmt = $conn->prepare($sql);
          $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added);
         $stmt->execute();
  $stmt->close();

选择配送状态

if ($shipping_status==1) {
        $sql="INSERT INTO shipping_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)";
        //  print_r($sql);
          $stmt = $conn->prepare($sql);
          $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added);
 $stmt->execute();
  $stmt->close();
        }

     if (empty($conn->real_escape_string(trim($_POST['shipping_status'])))) {
      $shipping_status=0;
$sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?)";
//  print_r($sql);
  $stmt = $conn->prepare($sql);
  $stmt->bind_param("ssssssiiiis", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added);

    }
    else{
    $shipping_status=1;
$sql="INSERT INTO billing_info (b_firstname, b_lastname, b_address, b_country, b_state, b_city, b_pincode, b_mobileno,login_user_id,shipping_status, b_date_of_added) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?,?);INSERT INTO shipping_info (s_firstname, s_lastname, s_address, s_country, s_state, s_city, s_pincode, s_mobileno,b_id) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?);";

  $stmt = $conn->prepare($sql);
  $stmt->bind_param("ssssssiiiisssssssiii", $b_firstname, $b_lastname, $b_address, $b_country, $b_state, $b_city, $b_pincode, $b_mobileno,$login_user_id=1,$shipping_status, $date_of_added,$s_firstname, $s_lastname, $s_address, $s_country, $s_state, $s_city, $s_pincode, $s_mobileno,LAST_INSERT_ID());
    }

Answer 3

在bind_params 之后你必须插入这个

$firstname = "John";
$lastname = "Doe";
$email = "john@example.com";
$stmt->execute();
