Ignoring the first input box you could also use a loop since the field names
are sequential. You could also handle the first field, by starting $i at 0
and only appending $i if it's greater than 0, but I don't want to clutter
the code. The code below assumes the fields aren't preset to values other
than those listed above.
for ( $i = 1; $i < 4; $i++ )
{
$field = 'interest' . $i;
if ( ! empty( $$field ) )
{
$flag = TRUE;
}
}
if ( $flag == TRUE )
{
echo "At least one was checked.";
}
