Should I post form data from a script to itself or separate the pages?

[dave247]

Ok basically I am building a simple web application where users can create accounts and log in and post bits of data that pertain to the project I am doing. I am using PHP scripts and logging data to an SQL database and I would like to make my entire site in one single script if this is a reasonable thing to do. I am concerned however about the $_POST data variable still holding the same information each time the page is refreshed... for example, I was testing my registration page and after I submitted some data from form fields, it seems like the data is still there in the $_POST variable since if I refresh the page the data gets sent again and I end up with another entry in my database. I know this is a rough explanation of what I am doing but my main point is that I want to know if it is best to just send data to an external script from a regular html page with a form, or if I can safely do it all in one single script.

 

Thanks

You can do it in one script. Just redirect back to the page after you're done processing it, and then you won't have the page refresh issue.
