$_POST没有得到任何值，我已经尝试了很多已经提到的堆栈溢出程序，但它们对我不起作用。我试过打印$_POST它是空的。我需要一些建议..请帮助
以前工作时它是在mysql数据库但我试图将数据库更改为sqlserver，现在它无法工作，但我不明白我没有对这个特定的代码做任何更改，我也看到了它也没有受到其他文件的影响。
在空状态下没有错误我自己写了检查它是否为空而且它总是显示为空我是否提交数据
我附上了一些与此相关的代码。

只有''数组为空时才会运行代码。
将您的代码更改为以下内容。
null除此之外，我认为没有问题。
答案 1 :(得分：1)
最好将提交按钮作为执行服务器端编码执行的关注中心。
因此，请检查是否已使用isset发送$ _POST数据：
if (isset($_POST['submit']))
{
// the data has successfully been sent
}
答案 2 :(得分：0)
你确定没问题吗？
if(empty($_POST))
如果$ _POST为空，你总是执行代码
if(!empty($_POST))
在$ _POST NOT 为空时执行
答案 3 :(得分：0)
这可能不是您的问题，但通常提交按钮是
<input type="submit" value="submit">
而不是
<button type="submit">Submit</button>
答案 4 :(得分：0)
我弄错了。我不知道如何，但表格的价值不仅转移到这个PHP文件，而且还转移到另一个php文件名check-email.php，这是我的项目的一部分，在register.php中没有提到。
我通过在堆栈溢出中查看与此类问题相关的帖子来了解问题，他说要检查PHP_error_log和Apache错误日志。那里的错误清楚地说明了。通过对check-email.php进行一些更改，它现在正常工作。无论如何，谢谢大家的帮助
