The problem is actually with f5, if I press f5, then an empty form flies to the base, how to fix it?

    for example, if the summit button is pressed with the name "go"

    That handler will start with

    if (isset($_REQUEST['go'])){ //заносим в базу }
    • Plus use the captcha and as an example, and after entering the base, do exit (header ("Location: / path")) - Maksym Prus

     <?php if(isset($_POST['sbt'])){ // fill db ?> <script type="text/javascript"> setTimeout(function(){location.replace(location.href);}, 3000); </script> <p>Форма заполнена, вы будете переадресованы через 3 секунды. Если не получилось - жмите <a href="<?=$_SERVER['PHP_SELF']?>">сюда</a>.</p> <?php } else { ?> <form action="<?=$_SERVER['PHP_SELF']?>" method="post"> <input type="submit" name="sbt" /> </form> <?php } ?>
