我讨厌寻求帮助。但是我花了很多时间试图弄清楚如何使用Recaptcha对此表格实施验证步骤。
[我了解我需要在某个地方定义私钥，但是其他大多数指南都在使用“ isset”函数，而我只是不在php的哪一部分进行此操作。
目前，该按钮显示出来并且可以检查。.但是，当我单击“提交”时，无论是否选中该框，它都会发送。 （只是在有帮助的情况下进行说明。）
谢谢，抱歉。

您可以在isset()条件中将if()功能设置为
if (isset($_POST)){...}
通过这意味着如果发布了某些内容，或者如果$_POST os设置为某个值，则代码会向前移动。
但是按照您前面提到的方式，它只是检查表单是否已发布，并且每次发布表单时都没有任何值，并且代码正在进一步移动。
