由于checkbox特殊性所以我们要获取它的值,在很我语言中都不一样的,在php教程 以我们是以数组形式来处理,并且利用遍历他的值,下面有大量实例。

$valid = true;
if (is_array($_get['input'])) {
    $valid = true;
    foreach($_get['input'] as $input) {
        if (!in_array($input, $options)) {
            $valid = false;
        }
    }
    if ($valid) {
        //process input
    }
}
?>
