Well the variable is undefined because your selector is wrong
Your selector
$('input[name=foo]:
would find
<input type="checkbox" name="foo" value="klaybul1" />
not "foo[]"...... different names, different results
besides, i don't believe (could be mistaken) that selecting checkboxes
and saying ".val()" won't result in an array of values but rather the
value of the first selected object only
this would work though
var vals = [];
$("input[name^='foo']").each(function() {
if (this.checked) { vals.push(this.value); }
});
//So now "vals" would be an array of selected values
to send through a post, which won't easily recognize an array
$.post(
"page.php",
{ values: vals.join(",") },
function(data) {
//do something with results
}
);
