如何调试不发送电子邮件的表单？

Question

我有一个应该发送电子邮件的kohana框架的表单构建。

当我按下“发送”按钮，一切似乎工作正常......没有错误信息......但没有电子邮件出现！

如果我在firebug中看不到任何东西，我可以在哪里看？

的应用程序日志状态

"error: Missing i18n entry contact.captcha.valid for language en_US"

，但我不知道怎么去的problem..any帮助欢迎.. 你的底，

Answer 1

从提供的小细节我想你使用的是来自Kohana中的的I18n库网站的国际化。另一种选择是您的网站使用Kohana消息来显示表单错误。

Validation类在生成验证错误时在内部使用__（）函数。我认为您没有关于APPPATH/messages/contact/captcha.php中指定的密钥valid的消息。

您应该尝试调查更多关于如何处理表单以及是否生成一些验证错误。验证码验证可能存在错误，尽管看起来没有错误，但可能存在错误消息，并且只能显示错误消息。

我的问题已解决！

我的电子邮件服务器设置不正确。我解决了后缀的问题，现在的评论形式，它应该工作，
