我目前正在做一个在 TutsPlus 上找到的教程。本教程是通过 PHP 将信息从 AS3 保存到 MySQL，然后检索此信息。
到目前为止，它有效。I 可以输入用户名和分数，保存到数据库中。但是有一个问题，我希望能够在表格中显示所有名称和分数，而不必搜索名称然后找到该特定用户的分数。
保存信息的代码（有效）如下。
package {
import flash.display.*;
import flash.events.*;
import flash.net.*;
public class register extends MovieClip {
public function register ():void {
register_button.buttonMode = true;
register_button.addEventListener(MouseEvent.MOUSE_DOWN, checkForm);
username_text.text = "";
userbio_text.text = "";
}
public function checkForm (e:MouseEvent):void {
if (username_text.text != "" && userbio_text.text != "") {
sendForm();
} else {
result_text.text = "PLEASE ENTER A NAME";
}
}
public function sendForm ():void {
/*
we use the URLVariables class to store our php variables
*/
var phpVars:URLVariables = new URLVariables();
phpVars.username = username_text.text;
phpVars.userbio = userbio_text.text;
/*
we use the URLRequest method to get the address of our php file and attach the php vars.
*/
var urlRequest:URLRequest = new URLRequest("localhost/php/register.php");
/*
the POST method is used here so we can use php's $_POST function in order to recieve our php variables.
*/
urlRequest.method = URLRequestMethod.POST;
/*
this attaches our php variables to the url request
*/
urlRequest.data = phpVars;
/*
we use the URLLoader class to send the request URLVariables to the php file
*/
var urlLoader:URLLoader = new URLLoader();
urlLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
/*
runs the function once the php file has spoken to flash
*/
urlLoader.addEventListener(Event.COMPLETE, showResult);
/*
we send the request to the php file
*/
urlLoader.load(urlRequest);
}
/*
function to show result
*/
public function showResult (e:Event):void {
result_text.text = "" + e.target.data.result_message;
}
}
}
从这里，我可以转到另一个应用程序并搜索用户名，然后显示该用户的分数。下面的代码：
package actions {
import flash.display.MovieClip;
import flash.events.*;
import flash.net.*;
import flash.text.*;
public class main extends MovieClip {
public function main ():void {
submit_button.buttonMode = true;
submit_button.addEventListener(MouseEvent.MOUSE_DOWN, checkLogin);
username.text = "";
}
public function checkLogin (e:MouseEvent):void {
if (username.text == "") {
username.text = "Enter your username";
}
else {
processLogin();
}
}
public function processLogin ():void {
var phpVars:URLVariables = new URLVariables();
var phpFileRequest:URLRequest = new URLRequest("http://xx.xx.xx.uk/~bf93fv/Source%202/php/controlpanel.php");
phpFileRequest.method = URLRequestMethod.POST;
phpFileRequest.data = phpVars;
var phpLoader:URLLoader = new URLLoader();
phpLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
phpLoader.addEventListener(Event.COMPLETE, showResult);
phpVars.systemCall = "checkLogin";
phpVars.username = username.text;
phpLoader.load(phpFileRequest);
}
public function showResult (event:Event):void {
result_text.autoSize = TextFieldAutoSize.LEFT;
result_text.text = "" + event.target.data.systemResult;
}
}
}
单独显示用户名和分数的 controlpanel.php 文件如下：
<?php
include_once "connect.php";
$username = $_POST['username'];
if ($_POST['systemCall'] == "checkLogin") {
$sql = "SELECT * FROM users WHERE username='$username'";
$query = mysql_query($sql);
$login_counter = mysql_num_rows($query);
if ($login_counter > 0) {
while ($data = mysql_fetch_array($query)) {
$userbio = $data["user_bio"];
print "systemResult=$username Scored $userbio";
}
}
else {
print "systemResult=The login details dont match our records.";
}
}
?>
有没有人知道任何简单的方法可以将数据库中的所有信息查看到表中？
