Best way to retrieve Checkbox values?

Hi,

I'm writing a script and I'm having some problems with retrieving checkbox values, say for example I have for checkbox's values are 1, 2, 3, 4 respectively
eg.

• 1
• 2
• 3
• 4

What I need it do is when the user checks for example 1 and 2 how do I make $check = 1,2 and so fourth.

$check = 1,2;

Code (markup):

Any help would be greatly appreciated, thanks a lot.

 

put a name attribute to the input tags like:

and
$fields = $_POST['fields'];
will save the selected values in an array;
You may need some functions dealing with arrays like
print_r; foreach; the html <pre> tag is also useful.

 

as Martin Said make the name of the checkbox field as and array "fields[]"


then in the page that process the form use the following
