error in my code: (was an extra parenthesis..)
should be:
if (isset($_POST['Submit'])) {
$result_check = mysql_query("select date, media, add, edit, name from test where date = '{$_POST['date']}' and media = '{$_POST['media']}' and add = '{$_POST['add']}' and edit = {$_POST['edit']} and name = '{$_POST['name']}'") or die("Query error: " . mysql_error());
if (mysql_num_rows($result_ch
$sql = "INSERT INTO test(date,media,add,edit,n
$result = mysql_query($sql) or die(mysql_error());
}
}

as i have an id in there with auto incresment would this all code work if everything was the same except the auto id
yup. this code won't add your item again.
but, if you don't want it to be strict, like you can add same item again, then the code will never add the item once you refresh.

If you're refering to the code I wrote, then no.
This code will not work if you use the auto_incremented ID field.
My code simply checks if such a record exists. If so... don't add a new one.
If you want to be able to add more rows later, but not right now... (best explanation I could come up with now)
I suggest adding a field call f.ex: ts (short for timestamp)
Then say: if ts of last similar row is older than 5minutes, OK add another row.
Best suggestion I can come up with now.

Also:
Have a look at this thread: https://www.experts-exchange.com/questions/21481938/POSTed-Variables.html
Diablo84's last post is a simple and easy fix at this.
Basically what he says is:
After the form/POSTDATA has been processed once, redirect to the same page.
This will clear the POSTDATA, and stop addition of more records.
To account for this, your code will be:
if (isset($_POST['Submit'])) {
$sql = "INSERT INTO test(date,media,add,edit,n
$result = mysql_query($sql) or die(mysql_error());
header("location: {$_SERVER['PHP_SELF']}");
}
