Duplicate php value
 

Hello all,

I'm a learning php this year but i encounters some problems.

One of them is about php value. The problem is how do i do to prevent a php file from resending the same values into the database whenever the page is refreshed?

Anyone help?


Thanks,

Asep

Check the database and see if the data is there already. If it is, then do not enter it, if it is not then enter it.

You can use a cookie or session variable to determine if the current page has already been submitted to decide if you should do an insert or not.

Cookies can be changed client side and sessions can be hijacked. If you need something solid then check on the server side and not the client side. Otherwise you will end up with duplicate values.
