If you have multiple checkboxes :

HTML


<form name="myform" action="" method="POST">
<input type="checkbox" name="options[]" value="Mac OS X">Mac OS X
<input type="checkbox" name="options[]" value="Linux">Linux
<input type="checkbox" name="options[]" value="Windows"> Windows
<input type="submit" value="Send me your name!">
</form>

You can get the count using this :

php

$boxcount = isset($_POST['options']) ? count($_POST['options']) : 0;

echo $boxcount;
