Alternative to hit the "Back Button"

[joaquin112]

I have a client who asked for a page where people order products for his site. This is then sent to the shopping cart. I am currently displaying an error message, "Please click the back button to try again", but my client does not want this. Is there a simple way with PHP to redirect users to the previous page, or should I code the custom error handling by hand?

There are a number of options, really. You could code the previous page link into this page they are on, you could use a redirect to push them back to that page, or you could process messages and include the html source from the previous page again.

The problem is that all the pages are actually in a single script. Is there any way to make PHP display a button which, on click, returns the user to the previous page and posts exactly the same $_POST? I am not sure if I am explaining this properly. Thanks anyway!

If the button was in a form you could pass back all posted variables in either hidden form fields or in a session. Then, when you get back to the page you were on you would read these values in if they existed and print them in the "value" attribute of the <input> element for that page.
