How could I use the $.prettyPhoto.close(); in a php page?

[wffger]

I use the prettyPhoto.
I open an External page B(iframe) in the page A. Then I want to click an button and submit a form to a .php page C.
How can I close the page B and return to the page A just like I click on the black background around the iframe, after I submit the form in the page B?

You'll need to use top or parent (or window. in front of either) to access the parent page. Call this onload from the PHP page C, e.g.

top.$.prettyPhoto.close();
