无法发送邮件PHP Recaptcha

Question

我对recaptcha遇到问题，即使我正确输入了代码，它也无法发送邮件，我尝试了很多次，甚至还有其他人尝试它和另一个人，其次是在contact.php

Answer 1

Your variable is $response, but you're checking to see if $resp is not valid. Change this:

    if (!($resp->is_valid)) {
        $captchaErrorMsg = true;
    }

To

    if (!($response->is_valid)) {
        $captchaErrorMsg = true;
    }

Answer 2

The problem might be the way you're checking value of $captchaerrorMsg.

<?php if ($captchaErrorMsg){ ?>    
    <p style="color:red">Please enter correct verification code.</p>
<?php } ?>

PHP does evaluate what it think you're checking when you don't clearly specify what it is. Therefore does the above code also run when $captchaErrorMsg is 1, when it is true or even when the variable just contains a character, like 'x'.

You only want to run the above code when error message is true , therefore you could do like this:

<?php if ($captchaErrorMsg === true){ ?>    
    <p style="color:red">Please enter correct verification code.</p>
<?php } ?>

If it still doesn't work, you will have to figure out the actual value you're getting. Just do a var_dump of the variable like this:

var_dump($captchaErrorMsg);

If this doesn't work, look at this workaround at weird reCaptcha error in PHP
