如何使用 PDO POST Bootstrap 模态形式值到 MYSQL 数据库

Question

需要您的帮助来解决本应非常简单的问题。

我在 Bootstrap 中有一个收集客户信息的模态表单，我希望将此信息保存在 MYSQL 数据库中。

我没有收到任何错误，但值没有插入到数据库中 table。 PDO 连接似乎是因为 table 中的自动增量值在提交时被添加（但不是表单中的值）。

模态表单代码如下：

<!-- Modal Insert Form -->

<div class="modal fade" id="insert" tabindex="-1" role="dialog" aria-labelledby="insert" aria-hidden="true">

    <div class="modal-dialog">

        <div class="modal-content">

            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">
                    <span class="glyphicon glyphicon-remove" aria-hidden="true"></span>
                </button>
                <h4 class="modal-title custom_align" id="Heading">Add New Customer Detail</h4>
            </div>

            <form class="form-horizontal" method="post" action="customers_add.php">  

            <div class="modal-body">
                    
             <div class="row">
             <div class="col-xs-6">
                 <input name="firstname" id="firstname" type="text" class="form-control" placeholder="First Name">                 
                 
             </div>
             <div class="col-xs-6">
                 <input type="text" class="form-control" placeholder="Last Name">
             </div>
         </div>
         
  <br>
  
  <div class="row">
             <div class="col-xs-12">
                 <input type="text" class="form-control" name="company" placeholder="Company">
             </div>
         </div>
         
  <br>
                
                <div class="row">
             <div class="col-xs-12">
                 <input type="text" class="form-control" name="address1" placeholder="Address Line 1">
             </div>
         </div>
         
  <br>
  
  <div class="row">
             <div class="col-xs-12">
                 <input type="text" class="form-control" name="address2" placeholder="Address Line 2">
             </div>
         </div>
         
  <br>

         <div class="row">
             <div class="col-xs-4">
                 <input type="text" class="form-control" name="town" placeholder="Town">
             </div>
             <div class="col-xs-4">
                 <input type="text" class="form-control" name="county" placeholder="County">

             </div>
         </div>
         
         <br>

  <div class="row">
             <div class="col-xs-6">
                 <input type="text" class="form-control" name="telephone1" placeholder="Telephone 1">
             </div>
             <div class="col-xs-6">
                 <input type="text" class="form-control" name="telephone2" placeholder="Telephone 2">

         </div>
         
         <br>                     

         <div class="row">
             <div class="col-xs-6">
                 <input type="text" class="form-control" name="website" placeholder="Website">
             </div>
             <div class="col-xs-6">
                 <input type="text" class="form-control" name="referredby" placeholder="Referred By">
             </div>
         </div>

  <br>
          
                <div class="form-group">
                    <div class="col-xs-12"> 
                     <textarea rows="2" class="form-control" name="dietaryreq" placeholder="Dietary Requirements"></textarea>
                    </div>
                </div>

  <div class="form-group">
                    <div class="col-xs-12"> 
                     <textarea rows="2" class="form-control" name="notes" placeholder="Notes"></textarea>
                    </div>
                </div>

            </div>

            <div class="modal-footer ">
                
                <button type="submit" name="submit" id="submit" class="btn btn-success btn-lg" style="width: 100%;" value="Add Customer">
                 <span class="glyphicon glyphicon-ok-sign"></span>
                     Add New Customer
                </button>
               
            </div>
     </form> 
        </div> <!-- /.modal-content --> 

    </div> <!-- /.modal-dialog --> 

</div>

... 这是应该将表单值处理到 mysql 数据库中的 php：

<?php

include('config.php');

// check if variable is set and Add Customer Button pressed.
if(isset($_POST["submit"])=="Add Customer")

{

// Define Variables
$userref = $_SESSION['user']['User_Ref'];
$customerref = $POST[customerref];
$firstname = $POST[firstname];
$lastname = $POST[lastname];
$company = $POST[company];
$addressline1 = $POST[addressline1];
$addressline2 = $POST[addressline2];
$town = $POST[town];
$county = $POST[county];
$postcode = $POST[postcode];
$telephone1 = $POST[telephone1];
$telephone2 = $POST[telephone2];
$emailaddress = $POST[emailaddress];
$website = $POST[website];
$referredby = $POST[referredby];
$dietaryreq = $POST[dietaryreq];
$notes = $POST[notes];

// Prepare SQL Query
$STM = $db->prepare("INSERT INTO Customers(User_Ref, Customer_Ref, First_Name, Last_Name, Company, Address_Line_1, Address_Line_2, Town, County, Post_Code, Telephone_1, Telephone_2, Email_Address, Website, Referred_By, Dietary_Req, Notes) VALUES (:userref,:customerref,:firstname,:lastname,:company,:addressline1,:addressline2,:town,:county,:postcode,:telephone1,:telephone2,:emailaddress,:website,:referredby,:dietaryreq,:notes)");
     
// Bind parameters, Named parameters always start with colon(:)
$STM->bindParam(':userref',$userref);
$STM->bindParam(':customerref',$customerref);
$STM->bindParam(':firstname',$firstname);
$STM->bindParam(':lastname',$lastname);
$STM->bindParam(':company',$company);
$STM->bindParam(':addressline1',$addressline1);
$STM->bindParam(':addressline2',$addressline2);
$STM->bindParam(':town',$town);
$STM->bindParam(':county',$county);
$STM->bindParam(':postcode',$postcode);
$STM->bindParam(':telephone1',$telephone1);
$STM->bindParam(':telephone2',$telephone2);
$STM->bindParam(':emailaddress',$emailaddress);
$STM->bindParam(':website',$website);
$STM->bindParam(':referredby',$referredby);
$STM->bindParam(':dietaryreq',$dietaryreq);
$STM->bindParam(':notes',$notes);

// Execute prepared statement
$STM->execute();
     
// Redirecting it to other page where we will show success message.
header("location:customers.php");                 
}

?>

希望修复起来很简单，谢谢

Answer 1

我想你错过了变量定义中的引号和下划线

// [...]
$customerref = $_POST['customerref'];
//[...]

Answer 2

当您省略引号时，PHP 认为您在 POST 超全局中的键是一个定义的常量，并且在您可能的应用程序的所有范围内都可以找到：

$customerref = $POST[customerref];

当PHP找不到这个常量时，它会发送一个错误。

如果您的代码和数据库中一切顺利，那么错误就在 POST[key] 赋值中。

然后尝试在超全局POST两边加上引号:

$customerref = $POST['customerref'];
