How to send JS variable to php iFrame

Question

I have this variable on my form

<script>
     var type = 2;
</script>

and on the same page I am calling this iFrame

<iframe src='http://www.genpowerusa.com/crm/formal_quote_new2.php' frameborder='0'></iframe>

What I am unsure is, how could I send the variable to the php form and use the variable on the quote form, the variable is static, I have two pages that call the same iFrame.

Is such thing possible?

Answer 1

Assign an id to your iframe:

<iframe id='foo' src='http://www.genpowerusa.com/crm/formal_quote_new2.php' frameborder='0'></iframe>

Add a js line:

document.getElementByid("foo").src='http://www.genpowerusa.com/crm/formal_quote_new2.php?type='+type;

What this does is,pass your variable as a PHP url parameter.You can access it by using the following code in php:

$type=$_GET['type'];

Answer 2

Sending information via javascript to a frame that is not in the domain of the scope is not possible, because of cross site scripting . That would not be secure (eg imagine inserting an iframe with Facebook and grabbing some data from the frame...).
