所以我正在制作联系表单，当我们点击提交时，它应该向管理员发送包含输入的电子邮件。电子邮件功能已经工作，我缺少的是验证输入字段是否为空。我尝试在输入标记中添加必需的属性。它适用于localhost，但由于某种原因不在服务器上。此外，它需要弹出一条消息，确认您已提交表单。我在这里使用了 onclick 功能。但是我无法澄清它是否有效，因为它只需要在提交成功且没有空字段时弹出消息。
这是我使用的代码。联系已经建立。

有不同的方法吗？
答案 0 :(得分：-1)
这是我用作内部开发工具一部分的验证器。它是服务器端，是更大框架的一部分，但它对你来说还可以。

}
这样的呼叫验证：
$validator = new InputValidation();
$val = $validator->validateInputs($data);
if (isset($val['error']) && $val['error'] == true) {
// do whatever
);
}
验证器还接受其他可选参数，如
$ exceptionList ['formField'，'anotherFormFiled'] 用于免除某些字段的验证
$ alias传递为数组（'formField'=＆gt;'Form Filed Caption'） 用于显示自定义字段标题
$ filters as ['email'=＆gt;数组（'must'=＆gt;“@”）] 用于验证输入。例如电子邮件
