submit form to parent/main window from child window, FireFox 2.0


Recommended Posts

THE GOAL: Open child.php with the link on main.php. Fill out the form on child.php and submit the form variable back to main.php in the window that is already open. Close the window for child.php automatically after it submits the form. Display the contents of the variable on main.php.

 

THE PROBLEM: This is just a little test that I am putting together to incorporate into a larger project. I have had many years of experience with HTML and a couple with PHP, but I am starting to jump into combining this with Javascript and of course now I am running into browser specific issues. The following code works in IE 7 fully, but does not display the variable back on main.php using Mozilla 2.0. Possibly, the form variable is never even sent to the page (no way to prove or disprove that with my skill level).

 

[main.php]
