我需要将getrowid更改为在所选行中获取id的值,如何???

这是我的data.php

<?php
error_reporting(0);
#Include the connect.php file
include('connect.php');
#Connect to the database
//connection String
$connect = mysql_connect($hostname, $username, $password)
or die('Could not connect: ' . mysql_error());
//Select The database
$bool = mysql_select_db($database, $connect);
if ($bool === False){
   print "can't find $database";
}
// get data and store in a json array
$query = "SELECT * FROM weekang";
if (isset($_GET['insert']))
{
    // INSERT COMMAND 
    $insert_query = "INSERT INTO `weekang`(`id`, `name`, `email`, `subject`, `confirmcode`, `username`, `password`) VALUES ('".$_GET['id']."','".$_GET['name']."','".$_GET['email']."','".$_GET['subject']."','".$_GET['confirmcode']."','".$_GET['username']."','".$_GET['password']."')";

   $result = mysql_query($insert_query) or die("SQL Error 1: " . mysql_error());
   echo $result;
}
else if (isset($_GET['update']))
{
    // UPDATE COMMAND 
    $update_query = "UPDATE `weekang` SET `name`='".$_GET['name']."',
    `email`='".$_GET['email']."',
    `subject`='".$_GET['subject']."',
    `confirmcode`='".$_GET['confirmcode']."',
    `username`='".$_GET['username']."',
    `password`='".$_GET['password']."' WHERE `id`='".$_GET['id']."'";
     $result = mysql_query($update_query) or die("SQL Error 1: " . mysql_error());
     echo $result;
}
else if (isset($_GET['delete']))
{
    // DELETE COMMAND 
    $delete_query = "DELETE FROM `weekang` WHERE `id`='".$_GET['id']."'";   
    $result = mysql_query($delete_query) or die("SQL Error 1: " . mysql_error());
    echo $result;
}
else
{
    // SELECT COMMAND
    $result = mysql_query($query) or die("SQL Error 1: " . mysql_error());
    while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
        $weekang[] = array(
            'id' => $row['id'],
            'name' => $row['name'],
            'email' => $row['email'],
            'subject' => $row['subject'],
            'confirmcode' => $row['confirmcode'],
            'username' => $row['username'],
            'password' => $row['password']
          );
    }

    echo json_encode($weekang);
}
?>

您可以使用'getrowdata'方法。它将返回特定索引处的数据记录。
