Hey, i Just made my first script ever! (YA!!!)

It is a very basic script that will give people a quote depending on what options they select from a form.

Anyway,It works fine but i would just like someone to look over it and tell me if there is a way i can write cleaner, point out any mistakes i make, and any improvements i should consider applying to my future scripts. THANKS!

<?php
//Only process if Send button was pressed
if (array_key_exists('send', $_POST)) {

//Assign Value according to numer of pages requires
if ($_POST['pages'] == 'five') {
$multi_pages ='10.00';
}
elseif ($_POST['pages'] == 'ten'){
$multi_pages = '20.00';
}
elseif ($_POST['pages'] == 'fifteen'){
$multi_pages = '30.00';
}
elseif ($_POST['pages'] == 'over_fifteen'){
$multi_pages = '40.00';
}
else {
$multi_pages = '0';
}

//Assign Value according to numer of images to be supplied
if ($_POST['images'] == 'no') {
$multi_images = '10.00';
}
elseif ($_POST['images'] == 'few'){
$multi_images = '$20.00';

I personally would use a switch for this, it would clean it up quite alot.

A switch would be great for this... and it looks very clean... the only problem there is that I don't think you can use variables within a switch...which means that you won't be able to add up the cost of the pages and the cost of the images.

Just for your own personal reference... this is how you would use the switch for your case... but still make reference to the URL thesavior posted =]

if (array_key_exists('send', $_POST)) {

switch ($_POST['pages']) {
case five:
echo '$10.00';
break;
case ten:
echo '$20.00';
break;
case fifteen:
echo '$30.00';
break;
case over_fifteen:
echo '$40.00';
break;
default:
echo '$0.00';
break;
}
}

You could eliminate the need for switches altogether if you used more useful form values.

<?php
//Only process if Send button was pressed
if (array_key_exists('send', $_POST)) {

//Assign Value according to number of pages requires
$multi_pages = $_POST['pages'] ? number_format($_POST['pages']*2,2) : 0;

//Assign Value according to numer of images to be supplied
$multi_images = $_POST['images'] ? number_format($_POST['images']*2,10) : 0;

}
?>

If you want to validate that form values are only the values you want to allow, replace

//Assign Value according to number of pages requires
$multi_pages = $_POST['pages'] ? number_format($_POST['pages']*2,2) : 0;

//Assign Value according to numer of images to be supplied
$multi_images = $_POST['images'] ? number_format($_POST['images']*2,10) : 0;

with

//Assign Value according to number of pages requires
$allowed = array(5,10,15,20);
$multi_pages = in_array($_POST['pages'],$allowed) ? number_format($_POST['pages']*2,2) : 0;

//Assign Value according to numer of images to be supplied
$allowed = array(1,2,3,4,5);
$multi_images = in_array($_POST['images'],$allowed) ? number_format($_POST['images']*2,10) : 0;
