我正在创建一个带有验证码的php联系表单，但我无法弄清楚如何实际获得验证码图像显示。到目前为止，它只显示了一个关闭按钮x和单词CAPTCHA图像代替真实的图像。我还想将name字段拆分为同一行上的First name和Last name两个字段。非常感谢任何帮助。下面是html代码和php代码:

该图像可能不会出现，因为captcha图像的路径是securimage/securimage_show.php，这可能相对于您的表单位置不正确。
像/securimage/securimage_show.php这样的名字可能更合适。也检查，以确保captcha图像显示正确，并在您的系统上工作通过转到securimage/example_form.php。
Securimage还提供了一种方法，可以为您呈现captcha html，这可能会更好地工作。在这种情况下，试试:
<?php
// show captcha HTML using Securimage::getCaptchaHtml()
require_once 'securimage.php'; // CHANGE THIS TO THE CORRECT PATH
$options = array();
echo Securimage::getCaptchaHtml($options);
?>
