JonnoTheDev Posted May 13, 2009 Share Posted May 13, 2009 No. Are you sure you are not just refreshing the page. This will resubmit the form. Quote Link to comment https://forums.phpfreaks.com/topic/157981-a-doubt-on-_postsubmit/#findComment-833291 Share on other sites More sharing options...
Cosizzle Posted May 13, 2009 Share Posted May 13, 2009 Where is the form going after you hit submit? If you have it change location I doubt it will say hello Quote Link to comment https://forums.phpfreaks.com/topic/157981-a-doubt-on-_postsubmit/#findComment-833307 Share on other sites More sharing options...
