无法弄清楚我的错误来自哪里，我确定问题出在电话号码上。我的课程说，电话号码preg_match是数字格式 555-5555 或 （888） 555-5555，但当我插入所有数据时，例如：名字、姓氏和电话号码这些格式，我收到错误"不是有效的电话号码"。请帮帮我，我想不通。
谢谢。
字段 phoneButton 被视为电话号码，因为它通过了您的条件if (preg_match("/phone/i",$field))，它的值"提交电话号码"然后被验证为电话号码，从而生成错误"提交电话号码不是有效的电话号码"。
"phoneButton"字段重命名为"提交按钮"，您应该没问题。
替换
$phone_patt = "/^[0-9)(xX -]{7,20}$/";
跟
$phone_patt = "/^([1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/";
