联系表格重定向到PHP错误页面

Question

我试图将我的HTML表单提交给PHP脚本（工作正常），但是PHP应该将它发送到电子邮件。相反，它最终会出现在错误页面上。所以我认为HTML代码不是问题，PHP中必须存在错误。任何人都可以帮助我解决这个错误？

更新：现在有没有更多的错误，但它重定向我到一个空白网站..

Answer 1

的代码

if (isset($_POST["submit"])) 

返回false表单被回发时，因为虽然您有一个带有name="submit"的按钮，但它没有value属性。因此，当您提交表单时，“submit”变量为空，导致isset返回false。

只需添加

value="submit" 

到您的按钮，例如

<button class="btn btn-primary col-sm-offset-5" name="submit" id="submit" type="submit" value="submit">Submit</button> 

N.B.没有要求value有任何特定的内容。 value="x"也会起作用 - 所有的代码测试都是存在一个值。
