adding numbers from 2 different arrays

space_cadet · June 23, 2011

I have a form that is working except for that I can't get the total amount from the two different arrays i have. $total = $extras + $additional isn't working and honestly, i have a growing feeling that it is not going to be that easy anyway! ... Any suggestions on what formula to use so that I can get a total dollar amount of all of the options that are selected?

One more thing...Can anyone with a fresh set of eyes see why the checkbox options are all being produced in a whole new table and not just a new row? I don't know if i can look through any more sets of <tr> and <td> tags! LOL

Thanks!!!!!

<?php

$value = array("Short Trip"=>15.99, "Long Trip"=>28.00, "Overnight"=>10.00);

if(isset($_POST['travel'])) {
$extras = array("brush"=>1.50, "shampoo"=>1.50, "toothpaste"=>1.50, "cream rinse"=>1.50);
if (isset($_POST['extras'])) {
	foreach ($_POST['extras'] as $additional) {
		echo "<table border =\"2\">
			<tr><td>Item</td><td>Charges</td></tr>
			<tr><td>".$_POST['travel']."</td>
			<td> $".$value[$_POST['travel']]."</td></tr>
			<tr>

    <td>".$additional."</td>
    <td> $".$extras[$additional]."</td>

    </tr>
			<tr><td>Your total</td> <td>".$total."</td></tr>
			</table>";
	}
}
}

?>
