IFrame and Parent window

Can an iframe install a cookie or session on the parent page? How do i get value in an iframe to the parent page without using Ajax? I am trying to pass an Id value from th开发者_C百科e iframe to the parent page and then submit it.

From within your iframe, you can reference the parent document using parent.document. If you had an input field in your parent window and wanted to set a value on it without using AJAX, you should simply be able to do the following using JavaScript:

parent.document.getElementById('myInputId').value = 'some value';
parent.document.getElementById('yourFormId').submit();

You can call functions in your parent page as well:

parent.someFunction();

I'm not sure about manipulating a parent's cookie(s) from a child frame, but your post it seems like all you need to do is store and submit a value. You won't be able to do it with just PHP.
