passing variable through Iframes?

[spires]

Hi

 

I'm new to Iframes and am having trouble passing PHP

varables from outside the Iframe to inside the Iframe.

 

this is what i'm trying at the moment:

main page

<iframe src="listings_text.php?time_frame=this" NAME="ishort" width="385" height="290"> </iframe>

 

 

I was thinking it would be something like this, but this is not working.

<?php
$time_frame = 'this';
?>
<iframe src="<?php echo 'listings_text.php?time_frame='.$time_frame.''; ?>" NAME="ishort" width="385" height="290"> </iframe>

 

 

This is the page that the Iframe links to, This is where i'm trying to get the variable.

<?php
$time_frame = $_GET['time_frame'];
echo $time_frame;
?>

 

 

I hope this makes sence,

Thank you for helping.
