I have an html page with checkboxes:

<input type=submit name=submit value=Submit>
and mailform2.php containing:
echo "you selected: <br>";
/* line 81 */ foreach ($_POST[option] as $a)
{
echo "$a";
}
but I'm getting the error:
you selected:

I googled some checkbox/foreach pages on google, but I don't see
where I'm going wrong. I'm running php 5.2.5 on Apache 2.2.4 on
Fedora Linux. Any help?
There's nothing wrong with your php code, but there is something
wrong with your html and methodology.
First, always use quotes in html for attributes and values (i.e.,
type="checkbox" value ="Submit").
Second, always plan for what the user may do (IOW clean your input).
If "none of the above" is an acceptable answer, then plan for it.
Cheers,
