Average score

[Teach]

Hi there!

Another quick question please.
We use a 'feedback' form which lets visitors choose a select from 1 - 10, with 1 being poor, 10 being excellent.

These are echo'ed across into our mailer as follows:

$msg .= "Type1.............. ".$_POST['type1']."\n";
$msg .= "Type2.............. ".$_POST['type2']."\n";
$msg .= "Type3.............. ".$_POST['type3']."\n";
$msg .= "Type4.............. ".$_POST['type4']."\n";
$msg .= "Type5.............. ".$_POST['type5']."\n\n";

Would it be possible to show an 'average' score for the selections in the form of:

$msg .= "Average score...... avghere\n";

Thanks!

Yes.

Would it be something like

$score = "".$_POST['type1']." + ".$_POST['type2']." + ".$_POST['type3']." + ".$_POST['type4']." + ".$_POST['type5']." / 5";
echo $score;

?

Why have you thrown in double quotes all over the place? Do you want PHP to store a literal " + " in the variable, or do you want it to add some numbers?

$score = ($_POST['type1'] + $_POST['type2'] + $_POST['type3'] + $_POST['type4'] + $_POST['type5']) / 5;

Also note the use of parenthesis (goes back to elementary math and order of operations).
