"Invalid Argument". Then $_POST['BannerSize'] is not what it is expecting.
Run a is_array() on it before you are using it.
Something like the following should do.
if ( isset($_POST['BannerSize']) && is_array($_POST['BannerSize']) ) {
$BannerSize = implode(',', $_POST['BannerSize']);
} else {
$BannerSize = "";
}
You could also go a little further and do something like this...
if ( isset($_POST['BannerSize']) ) {
if ( is_array($_POST['BannerSize']) ) {
$BannerSize = implode(',', $_POST['BannerSize']);
} else {
$BannerSize = $_POST['BannerSize'];
}
} else {
$BannerSize = "";
}
The latter one would assume that you would only receive a valid string
instead of an array if $_POST['BannerSize'] was set at all.
so... YMMV
