无法访问AJAX数据[PHP] [英] Unable to access AJAX data [PHP]

问题描述

主页上的表单（ index.php ）提交后，会在新标签中打开随机生成的URL。该随机网址运行的脚本名为 run.php

A form on my homepage (index.php) opens a randomly generated URL in a new tab, after being submitted. That random url is running a script called run.php

<form action="/run.php" method="POST" target="_blank">
    <input type="hidden" id="idgen" name="idgen" value="<?php echo $random ?>">
    <input type="text" name="userinput" id="userinput">
    <button type="submit" onclick="calcResult();">Go!</button>
</form>

我首页上的JS函数使用 userinput 数据来计算结果。

There are JS functions on my homepage that use the userinput data to calculate a result.

我正在尝试使用AJAX从我的 index.php 到表单生成的随机网址。

I'm trying to use AJAX to send a value from my index.php to the random url generated by the form.

function calcResult() {
  var userinput = document.getElementById('userinput').value;
  var randomid = document.getElementById('idgen').value;

  // various functions

    $.ajax({
            type: "POST",
            url: 'http://example.com/' + randomid, // same random url as the form sends to
            data: {result: "Hello!"}, // using simple result for testing purposes
            success: function(response){
                console.log(response);
           }
});

我添加了<？php echo $ _POST ['result']; ？> 到 run.php 文件（表单打开的随机URL正在运行 run.php ）

I added <?php echo $_POST['result']; ?> to the run.php file (the random url that the form opens is running run.php)

console.log（response）表示它可以正常工作。它控制台记录整个 example.com/<randomID> 源代码（显示整个 run.php 代码），甚至替换<？php echo $ _POST ['result']; ？> 和 Hello。

console.log(response) shows it working. It console logs the entire example.com/<randomID> source code (shows entire run.php code), and even replaces <?php echo $_POST['result']; ?> with "Hello".

但是，这仅在控制台中有效。通过该表单打开该网页时，不会显示 Hello。

However, this only works in the console. When that webpage is opened by the form, "Hello" is not shown.

我有一个MySQL数据库，可以从 run.php 文件。我尝试对 $ _ POST ['result']; 做同样的事情，但是没有运气。

I have a MySQL database that I insert values into from the run.php file. I tried to do the same for $_POST['result']; with no luck.

没有使用上述代码时出现控制台错误，错误日志中也没有致命错误。

There are no console errors when I use the above code, nor are there any fatal errors in the error log.

其他信息

• 表单提交到 run.php ，其中包含 header（'Location：http ：//example.com/'.$_POST ['idgen']）; 以便重定向到随机网址。


• 使用htaccess的RewriteRule RewriteRule ^（[0-9a-zA-Z] +）$ /run.php?idgen=$1 [L]


• 试图使用'Flight'框架，但在尝试与它一起使用JS函数时遇到问题。

• The form submits to run.php which contains header('Location: http://example.com/'.$_POST['idgen']); in order to redirect to the random url.
• The random urls exist using a htaccess RewriteRule RewriteRule ^([0-9a-zA-Z]+)$ /run.php?idgen=$1 [L]
• Attempted to use 'Flight' framework, but was runnning into issues when trying to use JS functions with it.

目标

• 总体目标是将结果（从我首页的JavaScript函数获得）发送到PHP。这样，它们将显示在提交表单后打开的随机URL上-这样我就可以显示它们，并将它们添加到数据库等。

推荐答案

您可以尝试JavaScript的windows.location并传递您的值而不是标头位置。

you can try windows.location of JavaScript and pass your value instead of header location.
