Can I Pass a URL variable to an IFrame using PHP?

Question

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>";
?>

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

its

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.

Any advice appreciated.

Thanks

Simon

Answer 1

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

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>";

will be outputted as

 <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.

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>";

And it should work.

Answer 2

• Add http:// before sitename.com.au/
• Change memberid='$val' to memberid=$val' [remove that single quote on left of $val]

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

Seems that the

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

 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.
