Question

我已经制作了一个编辑表格......但是当我按下编辑按钮时......它可以工作......当完成编辑后如果按下更新按钮...它会进入主页但没有更新字段。

edit.page

<body>
<table align="center">
<tr>

</tr>
<tr>
<td>
<table border="2">
<th>SL</th>
<th>name</th>
<th>address</th>
<th>action</th>
<?php
include"dbc.php";//database conncetion
$order = "select * from tbl_record";
$result = mysqli_query($con,$order);
while ($row=mysqli_fetch_array($result)){
echo ("<tr><td>$row[employees_number]</td>");
echo ("<td>$row[name]</td>");
echo ("<td>$row[address]</td>");
echo ("<td><a href=\"edit_form.php?id=$row[employees_number]\">Edit</a></td></tr>");
}
mysqli_close($con);
?>
</table>
</td>
</tr>
</table>
</body>
</html>

编辑表格

<body>
<table border=2>
  <tr>
    <td align=center>Form Edit Employees Data</td>
  </tr>
  <tr>
    <td>
      <table border="1">
      <?php
      include "dbc.php";//database connection
      $id = $_GET["id"];
      $order = "SELECT * FROM tbl_record where employees_number='$id'";
      $result = mysqli_query($con,$order);
      $row = mysqli_fetch_array($result);
      ?>
      <form method="post" action="edit_data.php">
      <input type="hidden" name="id" value="<?php echo "$row[employees_number]"?>">
        <tr>        
          <td>Name</td>
          <td>
            <input type="text" name="name" 
        size="20" value="<?php echo "$row[name]"?>">
          </td>
        </tr>
        <tr>
          <td>Address</td>
          <td>
            <input type="text" name="address" size="40" 
          value="<?php echo "$row[address]"?>">
          </td>
        </tr>
        <tr>
          <td align="right">
            <input type="submit" 
          name="submit value" value="Edit">
          </td>
        </tr>
      </form>
      </table>
    </td>
  </tr>
</table>
</body>

更新页面

<?php
//edit_data.php
include "dbc.php";
if (isset($_POST['submit']))
{
 $id = $_GET['id'];
$name = $_POST["name"];
$address = $_POST["address"];

mysqli_query("UPDATE tbl_record SET name='$name', address='$address' WHERE employees_number='$id'")
 or die(mysqli_error()); 
}
header("location:edit.php");
?>

Answer 1

根据您的评论“我现在收到此错误mysqli_query（）预计至少有2个参数，1个给定...用于更新页面”

将您的连接参数添加到查询中：

mysqli_query("UPDATE

它的内容为

mysqli_query($con, "UPDATE ...

另外，您的提交按钮应显示为：

<input type="submit" name="submit" value="Edit">

现在它中的name="submit value"与它的条件语句不匹配 if (isset($_POST['submit']))

编辑数据后更新失败[无错误]
