You can also use an array :

form
input type=checkbox name=check[] value=someValue1nbsp;Some
Value 1
input type=checkbox name=check[] value=someValue2nbsp;Some
Value 2
input type=checkbox name=check[] value=someValue3nbsp;Some
Value 3
/form

to get the the third value from the form you can do like this :

?php
echo $_POST[check][2];
?

Good basic examples, two notes though -
1) form method=post (blindingly obvious to most, but might confuse
some)
2) the name/value pair will only be POSTed if it's checked, so that
would only work if the first two were checked.

Some people like to pair all their checkboxes with a hidden of the same
name, the hiddens value will be sent if the checkbox isn't checked.
Personally, I prefer having an actual unique name for the checkbox when
you need to check a specific one.  If you don't need to check if 'the
third one' is set, but you're just getting - for e.g. - a list of pizza
toppings, then the order doesn't matter and [] works fine.  Otherwise
(if it does), give it a unique name:
input type=checkbox name=check[0] value=someValue1nbsp;Some
Value 1
input type=checkbox name=check[1] value=someValue2nbsp;Some
Value 2
input type=checkbox name=check[2] value=someValue3nbsp;Some
Value 3

(although a little more unique would be clearer :) )

The following method worked well for me using the ternary conditional 
operator (?:):


$step = (isset($_POST['step'])) ? $_POST['step'] : NULL;

isset checks to see if a field named 'step' was received thru a POST 
operation. The statement creates a variable named $step. If the field 
'step' was passed, it sets $step to it's value. If the field 'step' was not 
passed, it sets $step to NULL (you could set it to anything you wanted).


Be sure you keep it straight whether the field you are looking for was 
passed by a POST or a GET. If the field is appended on the URL, use 
$_GET['fieldname']. It is possible to receive formfields through a POST 
operation and fields on the URL (use GET) at the same time.
