//我有3个.php。代码没有给出任何错误，但它没有;修改数据。第一个是edit.php，这里是以下代码：

    <?php

       include"db.php";//database connection


        /*$result = mysql_query("SELECT * FROM inward ");
    $row = mysql_fetch_array($result);*/
          $order = "SELECT * FROM inward";
          $result = mysql_query($order);
          while ($row=mysql_fetch_array($result))
          {
           $inwardid = $row['inwardID'];    
                    echo "<tr align='center'>";

Answer 1

if(isset($_POST['save']))将其更改为：

，您的检查不正确

if(isset($_POST['submit']))

因为您没有任何名为save

的输入

Answer 2

在edit_data.php中

变化

if(isset($_POST['save']))

到

if(isset($_POST['submit']))

并输入mysql_query（$ order）;在if语句中

更改代码

include "db.php";
if(isset($_POST['save']))
{   
    $inreceiptno= $_POST['inreceiptno'] ;                   
    $inreceiptdt=$_POST['inreceiptdt'] ;
    $sendername=$_POST['sendername'] ;
    $senderaddress=$_POST['senderaddress'] ;
    $insubject=$_POST['insubject'] ;
    $inacceptedby=$_POST['inacceptedby'] ;
    $inreceiptmode=$_POST['inreceiptmode'] ;
    $remark=$_POST['remark'];
    $person=$_POST['person'];
    $duedate=$_POST['duedate'];
    $compliancemode=$_POST['compliancemode'];
    $adreceiptdate=$_POST['adreceiptdate'];
    $filename=$_POST['filename'];



$order= "UPDATE inward SET inreceiptno='$inreceiptno',
                                    inreceiptdt='$inreceiptdt',
                                    sendername='$sendername',
                                    senderaddress='$senderaddress',
                                    insubject='$insubject',
                                    inacceptedby='$inacceptedby',
                                    inreceiptmode='$inreceiptmode',
                                    remark='$remark',
                                    person='$person',
                                    duedate='$duedate',
                                    compliancemode='$compliancemode',
                                    adreceiptdate='$adreceiptdate',
                                    filename='$filename'
            WHERE inwardID='$id'";
mysql_query($order);
            }
header("location:edit.php");

?>
