Question

我选择了这个脚本，并且检查/验证了reCAPTCHA的工作原理。我迷失在那里，我必须添加PHP命令＆＃34;邮件到＆＃34;通过邮件获取联系表格。请参阅下面的代码。我必须在

之后将＆＃34;邮件添加到＆＃34; -stuff

if($response->success) {

正确？但我不知道这是怎么回事。 Evrytime我尝试s.th.我只得到＆＃34;试图获得非对象的属性＆＃34;对于＆＃34; if（$ response-＆gt; success）{＆＃34;是

<form class="form-horizontal" action="" name="contactForm" method="post">

<input type="text" name="nickname" class="input_nickname" placeholder="Name" required="required"/>
<input type="email" name="mail" class="input_mail" placeholder="Mail" required="required"/>
<input type="text" name="remotekey" class="input_key" placeholder="REMOTE private key (optional)"/>
<textarea type="text" name="message" class="input_message" placeholder="Message" required="required"/></textarea>

    } 

}

<div class="g-recaptcha" data-sitekey="<?php echo $siteKey; ?>"></div>
<button name="submit" type="submit" class="btn btn-default">Submit</button>
</form>

如何在我的自定义动态PHP网站中实现reCAPTCHA？
