If you are wanting to limit the number of selections (so the user can
only select 2 etc), instead of using checkboxes, I would use radio
buttons or select lists. Anyway, after making the selections and
submitting your form, on the next page you can access the data
selected by using $value=$_POST["obj_name"]; where obj_name is the
name value on your form. With radio buttons, checkboxes, or select
lists the information placed in $value will be whatever you have setup
for the form objects value, or option value. Use $_POST only if you
are using POST for the method to submit the form, otherwise if you use
GET for the method, use $_GET.

It's not too hard. In our first page, have something like:

<form name="form1" method="post" action="/page2.php">
<input type="checkbox" name="user[]" value="1">
<input type="checkbox" name="user[]" value="2">
<input type="checkbox" name="user[]" value="3">
<input type="checkbox" name="user[]" value="4">
</form>

In your second page, $_POST['user'] contain the data:

if (isset($_POST['user'])) {
if (count($_POST['user'])) > 2) :
echo "Too many users selected!";
}
else {
foreach ($_POST['user'] as $user) {
// validate and handle the data here
}
}
}
else {
echo "No users selected";
}

A few points that you must keep in mind....

1. If you want to limit the number of selections to the user, one way
you can do this is with JavaScript. In that case, be sure that the use
of Name and Id properties of the checkboxes is ok. For example,
usually the name of a collection of checkboxes is
NAME='checkbox_name[]' and the id can be ID='checkbox_id_1'. Why?
Because the PHP script take the value of NAME as an array with
$_POST['checkbox_name'], and some function with JavaScript can limit
the number of selected options, using the ID (must be unique!!!!).
Only the selected options are submitting to the PHP script.
2. Be careful, the Radio control only accept one selection.
3. If you are using a Select Multiple control, be sure that you are
selecting every selected option before submitting the information of
the form.

I hope this help.

Sorry for my english.....

And also check it on the server end in case the user has javascript
disabled.

Which is why I use checkboxes.
