you could first check for isset($_POST['keyword']) and then if that passes
check what keywords you have. or you could write an additional html tag to
the page like. <input type="hidden" name="keyword[]" value="NA">. This
would force the $_POST['keyword'] array to exist and then you'd have to
strip that from your array when processing it

Subject: Determining if checkbox is selected in PHP
09/09/2003 08:09

I'm storing the values from a groups of checkboxes
in an array "keyword[]", but $_POST['keyword'] is
undefined if none of the checkboxes is checked.
I tried using "in_array()" with $_POST to determine
if any of the group of 'keyword' checkboxes is checked,
but can't get it to work; does anyone have any
suggestions?
