Thread: Duplicate php value problem

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,

I'm not sure if the OP still needs the answer, but others might.

Try something called PRG (or post->redirect->get)...

Basically, use the POST method to send data to a page.
That page then processes the information, then redirects the user to another page with any necessary values in GET form (page.php?out=variables).
The receiving page simply displays the required output.

Now, when a users refreshes their browser, they'll be on the output page, so they can refresh it as much as they want without interfering with your database, or doing any double-processing.

are you looping? if so check your conditions. if you are trying to insert single row then dont use loops . just get values, assign to php variables, and using mysql query insert them into your db.
