hey all, i am a bit lost on this one. i have a single php page it has a login form a submit new timesheet form and a display my timesheets table. this is updated as soon as the user submits a new timesheet. my issue is, after a timesheet has been submitted once, the table will add a row from the database and its great. but if i page refresh, it submits another identical timesheet. this happens even if i unset all the post variables. what is the best resolution. is there some kind of cookie i have to use? i'd rather avoid cookies. i'd also rather avoid having a second php file. i dont fully understand the $_POST variable concept. why are they not unset?

Here is my form: <FORM action="eatnlocal_validate.php" method="post"> <P> Name: <INPUT type="text" id="name"><BR> Restaurant name: <INPUT type="text" id="restaurant"><BR> Email: <INPUT type="text" id="email"><BR> <input type="submit" value="Submit" name="submit"> </P> </FORM> Here is my eatnlocal_validate.php: <?php if (isset($_POST['name']) && isset($_POST['restaurant']) && isset($_POST['email'])){ $name = $_POST['name']; $restaurant = $_POST['restaurant']; $email = $_POST['email']; header("Location: info_ad.php"); } else{ echo "Please enter all information. Click "?><a href = "info_form.php">Here</a><?php echo" to go back."; } ?> When I enter info into all three fields, I still get the else function. What am I doing wrong? Thanks
