AJAX投递后没返回信息?

不通过ajax直接post给b.php检查不要一上来就ajax，先确定b.php的执行情况先

已经确定了b.php能正常的了这一切在本机上测试时都是正常的就是上到网购空间后 a.php貌似已经POST数据给b.php的了可是b.php就是不返回数据给a.php 导致a.php一直等待都得不到数据~~

我的意思是你测试网上那个b.php，测本地的b.php有个鸟用

我曾试图在b.php上运行部分处理代码并在b.php输出,能测试出在空间上的b.php能正常运行, 但不能知道它到底有没有接受和返回信息给a.php

你不懂简单测试么？1.发送给b.php查看输出是否符合预想值
2.修改a发送给c.php查看c能否接收a的提交，以确定a有没有发送
3.预想以外的问题，例如编码

1.发送给b.php在本机上测试是符合的，这个应该不会随环境变化吧？
2.怎么才能知道c.php是否接受到来自a.php的数据？菜鸟请教~~
3.编码统一使用utf-8 这个在本机测试也是没问题的，这个也不会随环境变化吧?

b.php接受数据后怎么输出来验证是否符合要求？b.php都不打开的!

……看来你要从新学习，连基本的查错方式都不会1.本地检查和空间检查是两回事
2.最最最最最基本的检查方式就是echo
3.form提交数据给一个php，它不需要打开么？
4.别老想着ajax，你连最基本的都没搞定写一个html，里面有form提交给b.php
把这个html和b.php一起放到空间上，运行html，看b.php的输出结果

表单举例：<html>
<body><form action="welcome.php" method="post">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" />
</form></body>
</html> 上述HTML页面包含了两个输入框[input field]和一个提交[submit]按钮。当用户将信息填写完毕并点击提交按钮时，表单的数据将被发送至“welcome.php”文件。“welcome.php”文件如下所示：<html>
<body>Welcome <?php echo $_POST["name"]; ?>.<br />
You are <?php echo $_POST["age"]; ?> years old.</body>
</html> 上述脚本将输出下面这段结果：Welcome John.
You are 28 years old.
我按照上面说的对网购的那空间进行测试,输入框分别输入了asasas和22,结果输出了
Welcome .
You are years old. 这个难道是指空间不支持？我用360浏览器浏览该网页

所以说本地和空间测试是两码事写个phpinfo或者放个探针上去看看吧，希望不会是php3...

写个phpinfo或者放个探针上去？？
php3...？？什么？？

我是说希望你那个空间不是装的旧版php<? phpinfo(); ?>把上面这句保存为一个php放到你的空间上运行

在b.php提交后
print_r($_REQUEST);
看看是什么结果

上面的那些信息是空间的信息来的,b.php在空间里面运行的结果
还有我用<?php print_r($_REQUEST); ?> 测试的结果如下按#9楼的方法测试在welcome.php(等于这里的b.php)中加入如下代码:<html>
<body>Welcome <?php echo $_POST["name"]; ?>.<br />
You are <?php echo $_POST["age"]; ?> years old.<?php print_r($_REQUEST); ?></body>
</html> 输入 asas和111输出结果
Welcome .
You are years old.Array ( [name] => asas [age] => 111 [AJSTAT_ok_times] => 23 ) 好象是正常接受到的样子?

$_REQUEST接受了，但$_post没有接受，估计php.ini有问题你可以用$_REQUEST去取值，但这样就分不清get/post了，遇着别人恶意用url发数据给你就麻烦了

http://www.wangzhengdong.com/blog/servers-register-globals-close.html看这边文章，估计是这个问题

貌似文章没提到若register_globals=Off时不用$_REQUEST去取值(因为不安全)而该用什么去取值的问题!
只提到register_globals=On时可以用$_POST来取值

相反吧？register_globals=On时，$_post可能取不到值不安全就是我上面说的原因你再试一下b.php用 $_SERVER["REQUEST_METHOD"]看看能否判断传值方式？
最终问题还是要解决能用$_post，找那边客服问一下为何$_post没有值

那问题是不是要他们把设回register_globals=Off啊？

$_SERVER["REQUEST_METHOD"] 这个怎么打印出来？

直接echo 我看看输出而已

<html>
<body>Welcome <?php echo $_REQUEST["name"]; ?>.<br />
You are <?php echo $_REQUEST["age"]; ?> years old.<?php echo $_SERVER["REQUEST_METHOD"];?></body>
</html> Welcome asas.
You are 11 years old.GET

能不能自己处理下使它能用$_POST的方式投递数据的?

<html>
<body>Welcome <?php echo $_GET["name"]; ?>.<br />
You are <?php echo $_REQUEST["age"]; ?> years old.<?php echo $_SERVER["REQUEST_METHOD"];?></body>
</html>
Welcome asas.
You are 22 years old.GET

果然是get再输出这两个只给我看
_SERVER["QUERY_STRING"]
_SERVER["REQUEST_URI"]

<html>
<body>Welcome <?php echo $_GET["name"]; ?>.<br />
You are <?php echo $_REQUEST["age"]; ?> years old.
<?php echo $_SERVER["REQUEST_METHOD"];
echo $_SERVER["QUERY_STRING"];
echo $_SERVER["REQUEST_URI"];?></body>
</html> Welcome asasas.
You are 12112 years old. GETname=asasas&age=12112/images/welcome.php?name=asasas&age=12112

整理一下<html>
<body>Welcome <?php echo $_GET["name"]; ?>.<br />
You are <?php echo $_REQUEST["age"]; ?> years old.<br />
<?php echo $_SERVER["REQUEST_METHOD"]; ?><br />
<?php echo $_SERVER["QUERY_STRING"];?><br />
<?php echo $_SERVER["REQUEST_URI"];?><br /></body>
</html>
Welcome asas.
You are 11 years old.
GET
name=asas&age=11
/images/welcome.php?name=asas&age=11

这次绝对是晕倒了把你填数据的html源代码完整贴出来

就只有这么一点
<html>
<body><form action="welcome.php" method="post">
Name: <input type="text" name="name" />
Age: <input type="text" name="age" />
<input type="submit" />
</form></body>
</html>

上面那个用于填写的取名是 index.php的

唉，不知道你那是什么空间……难道post方法被禁用了？你现在可以把ajax改成get方法测试一下，如果成功的话，估计你那个空间不支持post
服务器把你的请求都按get发送了

ajax里面应该有个选项是选post method还是get的自己试着改吧，ajax我都快忘光了

ajax里面应该有个选项是选post method还是get的? 是参数设置? 还是环境的选项设置?
以下是我的ajax部分的代码
$.ajax(
{

type: "POST",
url : "Test2.php",
dataType:'JSON',
data: _Data,
//document.getElementById("text_out").value = "转换中..秒..";
success: function(json)
{
document.getElementById("text_out").value = json.Data;
}
});要改哪里?

改成下面这样后,我曾分别把a.php和b.php分别统一用$_POST,$_REQUEST,$_GET做测试,均无反应,
type: "POST"时我也分别用它们做测试可是一样都没反应本来a.php发送数据给b.php后b.php处理完数据后会自动返回数据给a.php 然后从a.php输出结果 b.php无须打开的,我所说的没反应是说在a.php里无法看见返回数据 , 这里有个前提type: "POST"时我在本机上做测试时是没问题的统一用的是用的是$_POST$.ajax(
{

type: "GET",
//type: "POST",
url : "Test2.php",
dataType:'JSON',
data: _Data,
//document.getElementById("text_out").value = "转换中..秒..";
success: function(json)
{
document.getElementById("text_out").value = json.Data;
}
});

可能ajax不是改那里，你过ajax版问，说明服务器限制php只能接受get方法，让别人帮忙改改

主要不知道你是什么空间，合约有没有限制条款，一般空间不可能限制post的
如果你那个是特别的服务空间就有可能因为安全原因限制，你问清楚客服是不是禁止了post如果不是专项服务，大不了换一家

那个想问下过ajax版问该怎么说和该不该把代码都贴出去?
