我可以使用PHP将URL变量传递给IFrame吗？ [英] Can I Pass a URL variable to an IFrame using PHP?

问题描述

之前我没有使用太多PHP（或根本没有），我有以下代码：

I've not used PHP much (or at all) before, and I have the following code:

<?php
$val = $_GET['ID'];
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid='$val'    width='100%' scrolling='vertical'></iframe>";
?>

我认为应该可以获取一个URL变量并将其传递给Iframe网址...我的问题是，当我点击页面时，这是打开而不是它：

I think that should be ok to take a URL variable and pass it to an Iframe url...my issue is that when I hit the page this is on instead of it being:

http://sitename.com/whats-on?ID=2

其

http://sitename.com/whats-on/?ID=2

我不知道之前斜线在哪里？？ID来自 - 但我认为这是导致我的问题 - iframe显示页面未找到消息。

I don't know where that slash before /?ID is coming from - but I believe it is causing my problem - the iframe displaying a page not found message.

任何建议表示赞赏。

谢谢

Simon

推荐答案

iFrame只需要一个网址 - 参数可以嵌入到网址中。

iFrames just take a url - and parameters can be embedded in urls just fine.

问题，如果我清楚地理解了这个问题，就是你在混淆你的报价：

The problem, if I understand the question clearly, is that you're mixing up your quotes:

 echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid='$val'
        width='100%' scrolling='vertical'></iframe>";

将输出为

 <iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=' 21254545' 
  width='100%' scrolling='vertical'></iframe>

其中21254545是iframe的一个属性，而不是url的一部分。

where 21254545 is an attribute of the iframe instead of part of the url.

假设您实际上不需要网址中的引号，请将回显线更改为：

Assuming that you don't actually need the quotes in the url, change the echo line to:

echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=$val' width='100%' scrolling='vertical'></iframe>";

它应该有效。
