arrays and arithmetic

[Anon]

Can anyone show me how to put into an array 5 variables from a form (all integers) and then calculate the total ?
Here is an example of my form:

all the values to be added are integers.

<input type=radio name=section1A value=2>
<input type=radio name=section1B value=5>
<input type=radio name=section1C value=3>
<input type=radio name=section1D value=1>
I have 24 input variables to be added up !

thanks,
Peter

Hi.

First of all, can you modify the name of the input fields? I have made this here. Try the next code. If i have understood you, it code will help you 🙂

<form action"forum.php" method="post">
<input type=radio name=section1 value="2">
<input type=radio name=section2 value="5">
<input type=radio name=section3 value="40">
<input type="submit">
</form>

<?
for ($i="1";$i<="24";$i++) {
eval( "\$total[\$i] = \$section".$i.";" );
$sum=$sum+$total[$i];
}
echo $sum;
?>

<form action"forum.php" method="post">
<input type=radio name=sesion[] value="55">
<input type=radio name=sesion[] value="66">
<input type=radio name=sesion[] value="44">
.
.
.
<input type="submit">
</form>

<?
for ($i=0;$i<count(sesion[]);$i++) {
$sum+=$sesion[$i];
}

echo $sum; // :-)
?>
