Why would a php script enter null data on refresh?

I have a php form ive made but every time i open the page the script sends empty data to the database – works fine with actually posting the real data to the database how can i stop the data entry on returning to the page

    what are you using to trigger the script to enter the data in the database? You would be using…
    if ($_POST){
    do something;
    }
    this way it will only send the data when someone submits the form. you can also is $_GET or $_REQUEST depending on your forms action.
