我在这个网站上找到了一个不错的表单验证插件:http://formvalidator.net/index.html
当我尝试实现服务器端验证时,插件似乎不起作用。它声明它会通过POST方法将url发送到我在属性data-validation-url中声明的url。但是当我尝试回显post变量时,它似乎没有在Web浏览器中显示。
有人可以帮忙调查一下吗?也许我可能在某处做错了什么。道歉,我对编程很新! :)

}
echo json_encode($response);
答案 0 :(得分:0)
编辑:我完全错过了用户名输入中的斜线,这就是问题所在,现在测试它,现在它会触发发布请求。
您只需在表单上添加方法帖子。
尝试使用适当的缩进,它更容易阅读,没有人会责怪你这样做。

检查一下,似乎工作正常。
祝你好运。
