Can I Pass a URL variable to an IFrame using PHP?
提问by Simon
I've not used PHP much (or at all) before, and I have the following code:
我以前很少（或根本没有）使用 PHP，我有以下代码：
<?php
$val = $_GET['ID'];
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid='$val' width='100%' scrolling='vertical'></iframe>";
?>
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:
我认为采用 URL 变量并将其传递给 iframe url 应该没问题……我的问题是，当我点击页面时，它是打开的，而不是：
http://sitename.com/whats-on?ID=2
its
它的
http://sitename.com/whats-on/?ID=2
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.
我不知道 /?ID 之前的斜杠是从哪里来的 - 但我相信这是导致我的问题 - 显示页面未找到消息的 iframe。
Any advice appreciated.

iFrames just take a url - and parameters can be embedded in urls just fine.
iFrame 只需要一个 url - 参数可以很好地嵌入到 url 中。
The problem, if I understand the question clearly, is that you're mixing up your quotes:
如果我清楚地理解这个问题，问题在于你混淆了你的报价：
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid='$val'
width='100%' scrolling='vertical'></iframe>";
will be outputted as
将输出为
<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=' 21254545'
width='100%' scrolling='vertical'></iframe>
where 21254545 is an attribute of the iframe instead of part of the url.
其中 21254545 是 iframe 的一个属性，而不是 url 的一部分。
Assuming that you don't actually need the quotes in the url, change the echo line to:
假设您实际上不需要 url 中的引号，请将 echo 行更改为：
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=$val' width='100%' scrolling='vertical'></iframe>";
And it should work.
它应该工作。

- Add http://before sitename.com.au/
- Change memberid='$val' to memberid=$val'[remove that single quoteon left of $val]
- 在 sitename.com.au/ 前添加http://
- 将 memberid='$val' 更改为memberid=$val'[删除$val 左侧的单引号]
<?php
$val = $_GET['ID'];
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=$val' width='100%' scrolling='vertical'></iframe>";
?>

Seems that the
似乎
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=$val' width='100%' scrolling='vertical'></iframe>";
doesn't work anymore. You have to add the variable like this
不工作了。你必须像这样添加变量
echo "<iframe src='sitename.com.au/directory/app/pagename.cfm?memberid=".$val."' width='100%' scrolling='vertical'></iframe>";
Since the anwser was from 2012... maybe PHP patched it to be used like that now.
由于 anwser 是从 2012 年开始的……也许 PHP 修补了它现在可以这样使用。
