Duplicate php value problem

[komrad]

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

Are you using a Mysql database? If you are then there is one simple way you can do it from there. If you can access your database, then all you have to do is make on of your fields 'unique'. This means that your database will not accept information into that field that is duplicates. I would recommend only using this on the field/column that you definately will not have duplicates in and it would be best to use it on your smallest field/column as it's an index of sorts. It may not be the best way, but it is one way.

PHP is a popular, free and efficient alternative to competitors such as Microsoft ASP.

In this PHP tutorial you will learn about PHP and how to run scripts on your server.

Another solution is to asign a default value of this variable(0 or NULL for example) and when you are sending this you have to check if this value is the value you have set and if you meet those values, do not send them
