accessing multiple values for a variable

[Brian]

I'm creating a simple order form that allows visitors to order
photographs from an artist's web site. For each photo available for
sale, there is a checkbox whose name is "photo". The form uses post
to transfer data to a php form, where the visitor will enter name and
contact info.

When I try to access the posted information in the destination php
form, I only get the last photo selected. How do I access these
values if the user selected more than one photo?

Change the name for the checkbox to "photo[]" - that makes
$_POST['photo'] an array that you can look at.

When PHP gets several form variables with the same name, each values
overrides the previous ones. You have two options:

* Give fields different names: photo01, photo02...
* Force an array: photo[], photo[]...

You can even mix both solutions ;-)

photo[1], photo[2]...
