I just verified that the form is infact posted twice (by IE) by using session variable. When form is posted I set a session variable after doing the import and at start of the same import script I check if the form has been already posted from session variable and if the form has already been posted just return to some other page which unsets that session variable. But still I want to find the cause of the problem. ----- Original Message ----- From: Dan Shirah To: Sukhwinder Singh Cc: php-windows@xxxxxxxxxxxxx Sent: Thursday, June 26, 2008 1:31 AM Subject: Re: IE/ IIS / PHP - Form posted twice in case of redirection Are you sure it's not something in your code? I am also using IE/IIS/PHP and I have a form that on submission closes the page and opens up a new window displaying "Your data has been saved" and it does not create 2 rows in my MSSQL database.
