错误方法不会返回任何内容,如您所见。代码如下:

表格:

<form action="ticket.php" method="post">
    <table>
        <tr>
            <td>Full Name:</td> 
            <td><input type="text" name="name" value="<?=(!empty($_POST['name'])) ? $_POST['name'] : ''?>" /></td>
        </tr>
        <tr>
            <td>E-mail:</td> 
            <td><input type="text" name="email" value="<?=(!empty($_POST['email'])) ? $_POST['email'] : ''?>" /></td>
        </tr>
        <tr>
            <td>Topic:</td>
            <td><input type="text" name="topic" value="<?=(!empty($_POST['topic'])) ? $_POST['topic'] : ''?>" /></td>
        </tr>
        <tr></tr>
        <tr>
            <td>Question:</td>
        </tr>
        <tr>
            <td colspan="2"><textarea cols="30" rows="5" name="question" "<?=(!empty($_POST['question'])) ? $_POST['question'] : ''?>"></textarea></td>
        </tr>
        <tr>
            <td colspan="2">
                <?php
                  require_once('recaptchalib.php');
                  $publickey = "public key here";
                  echo recaptcha_get_html($publickey);
                ?>
            </td>
        </tr>
        <br>
        <tr>
            <td colspan="2" style="text-align:center;"><input type="submit" name="submit" value="Submit Question" /></td>
        </tr>
    </table>
</form>

-您的本地主机版本是否正常工作?(记住,localhost或仅127.0.0.1)我直接在托管站点中进行测试。合乎逻辑的做法是使用reCaptcha制作尽可能简单的表单,并在本地服务器上进行测试,然后使用var_dump()输出您似乎已经安装并依赖的此类。仅仅使用谷歌提供的例子有什么不对?
