Passed variables in HREFs

[jeffpim]

New to PHP... I think there is a simple answer to this... I have a page with this simple link code:

 

<a href="details.php?id=847288">view details</a>

 

I want to be able to grab the id # and place in a new HREF within a SmartFrame on the 'details.php' page.

 

I currently have this code at the top of 'details.php'...

 

<?php

 

$id = $_GET['id'];

 

?>

 

My code for the SmartFrame is...

 

<iframe name="smart_frame" width="740" height="950" marginwidth="1" marginheight="1" src="http://www.riliving.com/SmartFrames/sfdetails.asp?MLSid=$id">

 

I can not get $id to display the passed variable of 847288 - I just get a blank SmartFrame.

 

When I hard code like below... it works correctly. How can I get $id to display 847288

 

<iframe name="smart_frame" width="740" height="950" marginwidth="1" marginheight="1" src="http://www.riliving.com/SmartFrames/sfdetails.asp?MLSid=847288">

Are you starting PHP and echoing the line?

 

Or maybe something like

 

<iframe name="smart_frame" width="740" height="950" marginwidth="1" marginheight="1" src="http://www.riliving.com/SmartFrames/sfdetails.asp?MLSid=<?php echo $id ?>">

 

I don't use iframes, so I'm just tossing out a idea.

Since that variable $id is a php variable, you can use it when its between the php '<?' '?>' tags. If you try and use it outside of the php tags, then I think you will just get the actually '$id' being passed instead of the '847288'

<?php echo $id ?> worked!

 

Thanks!
