basic php adding up costs of tick boxes help?

Question

hello.
i am really stuck on some 'basic' php scripting.
It's about adopting a camel online and isn't for a real website, just one for fun.

Basically, i have tick boxes for additional things people can buy for their camels. Example: breath minds, brush etc.
These things are selected byt he user by them clicking a tick box.

My question is, how do i give each item a value, and make the php add it up depending on wht the user choses?

Answer 1

Use the Binary values
Oh my god he is now talking about complex computer programming!!!!

1,2,4,8,16 etc.
well it actually looks
etc. 16, 8, 4, 2, 1

So if items 1 and 3 are ticked then the value is 5 which in binary is 101. So you now have a unique value for those two items.
Work out the other combinations and you will find that it is just like counting. But the results will give you the different values you need.
Have fun.

Answer 2

Just create a html form, it should have a submit button which points to the PHP page which will do the processing.

When the PHP page is loaded after the user hits submit, it will have access to an array called $POST which will contain all the values set in the form.
