Question

我在删除桌面上的某条记录时遇到问题。我目前所做的是为删除和编辑创建两个表单。出于某种原因，我无法获得已删除的所需ID。

我尝试回显从该表单传递的id的值。并且传递的ID是13.

所以基本上我为行做了一个循环。我在从某一行获取ID时遇到问题。

这是我桌子的截图。

这是我如何使用表单

customer.php

<div class="box-body table-responsive">
                                    <form id='edit' action="functions/edit.php" method="post"></form>
                                    <form id='delete' action="functions/delete.php" method="post"></form>
                                    <table id="example1" class="table table-bordered table-striped">
                                        <thead>
                                            <tr>
                                                <th>Actions</th>

                                        </tfoot>
                                    </table>


                            </div>

这里是我的delete.php的样子

<?php

  include('config.php');

  $deleteID = $_POST['id'];


  //----- Check if user to be deleted is the user in session -----//

  echo $deleteID;
  //   $deleteSQL = mysqli_query($conn, "delete from customer where id = '$deleteID'");


  echo "<script type='text/javascript'>alert('Deleted succesfuly');</script>";
  //header('Refresh: 0; url=../customers.php');

  //
?>

你的delete.php应该是这样的：

<?php
  include('config.php');
  $deleteID = $_POST['id'];
  // Create connection
  $conn = new mysqli($servername, $username, $password, $dbname);
  // Check connection
  if ($conn->connect_error) {
      die("Connection failed: " . $conn->connect_error);
  }
  $deleteSQL = mysqli_query($conn, "delete from customer where id = '$deleteID'");
  if ($conn->query($sql) === TRUE) {
      echo "<script type='text/javascript'>alert('Deleted succesfuly');</script>";
  //header('Refresh: 0; url=../customers.php');
  } else {
      echo "Error: " . $sql . "<br>" . $conn->error;
  }

  $conn->close();
  ?>

现在，如果在 config.php 中正确指定$servername, $username, $password, $dbname，这将有效。

你身边的编码很差。
