RE: [PHP] Disabling Browser "BACK" button From: Dan Vande More (dvm <email protected>)

I do it this way

Page1 (fill in data)->Page2(write data, instant redirect to p1, unless dies from php/mysql)

Then the only way to repost, is to push the forward button.

Well, OK, then, How do you design the app NOT to allow the form to POST
again when the user hits "BACK"

Additionally, it's all nice and good that your site works fine without using cookies, and don't take this offensively, but if the client cannot use the back button without getting mishapen results, then it doesn't sound as if the site is designed very efficiently.
