Pass variable to IFRAME

[prudens]

hi,

 

 

        I want to pass a few variables $var1 $var2 to iframe.php in IFRAME from MAIN. And I want iframe.php to read the $var1, $var2 and then send back $var3, $var4 to MAIN. How do I do it?

 

Thanks!

well you can pass value to the script inside iframe through $_GET, $_SESSION...

 

if you are calling things inside iframe on the client side, then you can use DOM.

passing variables back to main can be done using $_SESSION but i dont think this can be read from the client-side so you can use DOM here also.

I have similar issue.  I need to "pull variables" from the parent page on my child page so I can use it in several places on the child page

 

I am dynamically calling iframes so can't use the GET

 

Here is what I have in the parent

 

<script type="text/javascript">function populate(){

top.frames['frame1'].document.form2.from.value = '$email';

top.frames['frame1'].document.form2.name.value = '$fname $lname';

}

  </script>

 

 

That works before if the child page is "Form" as it sets the values.  But I have children pages that are just text and I want to be able to use the NAME within the text on the child page. 

 

"$FNAME $LNAME, thanks for visiting..."

I don't see why you can't use GET on dynamic child pages :S

You can actually use $_GET for that... I have been doing that several times on mine... even changing the content iframe with different scripts. $_GET works for me though. Why not yours?

Use sessions... You'll be able to continue the session into the iframes and grab your needed variable data that way.

Yep... use $_SESSION for globally indicated variables. But for content specific values... which is retrievable using JavaScript and cannot be identified when the page is loaded, use $_GET.
