Form question?... getting a total number

[rklutts]

Hi, I am very new to PHP... heck any type of programming as a matter of fact.

What I have is a project that involves the person filling out a one page order form that will be emailed to me in the end via PHP. But before they are done and ready to send out the info is there any way I can give them a total amount ($) of what they ordered? This of course may seem simple to some but I have no idea of where to begin. I am very green to programming and would like some input on the easiest way for me to accomplish this feat. Thanks in advance.

I guess this would be considered as a shopping cart of some kind. Is that true and if so can it be done??

Well yes, it is possible.

You could use say, Javascript to sum the values, or there could be an intermediate PHP page that serves as a confirmation page.

You could also have a seperate page inbetween which lists the goods the user ordered and does the math needed.

It kind of depends on how your order form is setup. If you have a list of products the customer can choose between, i would name them all the same name="products[]" value="price_in_numbers", to try and keep it easy.

Then on the next page you just use the function:

// Calculates the total sum of the values in the array (All the products the customer clicked)
$total_amount = array_sum($_POST['products']);

echo $total_amount;

Personally i would use an product ID in the checkboxes and retrieve the price info and product name from a database. But that would probably be to big of a mouthfull for you right now.
