我正在尝试将我的HTML表单提交到PHP脚本（工作正常），但PHP应该将其发送到电子邮件。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中必定存在错误。任何人都可以帮我解决这个错误吗？
更新：现在没有更多错误，但它会将我重定向到空白网站..
更新了HTML：

答案 0 :(得分：0)
代码
if (isset($_POST["submit"]))
返回false，因为虽然您有一个name="submit"的按钮，但它没有value属性。因此，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。 value没有要求具有任何特定内容。 value="x"也可以正常工作 - 所有代码测试都是值的存在。
