我正在使用PHPMailer脚本从用户填写的表单中发送电子邮件，然后用户从下拉列表中选择一个图像，然后该表单根据用户选择将相应的图像与电子邮件一起发送。所以它非常简单，我让它工作了一段时间，然后突然停止工作了，我什么也记不清了。我也在使用bootstrap和DDSlick（用于下拉列表）。
映像是错误日志中未定义的内容，所有其他信息都起作用！
这是错误：
Undefined index: image in /home/name/website/assets/php/store-email.php on line 8

最佳答案
事实证明DDSlick是导致无法发送图像的原因。
尝试在您的Ajax请求之前添加以下内容：
$(document).find(".dd-selected-value").attr("name","image");
这会将我们正在寻找的缺少名称属性添加到DDSlick用于所选“选项”的隐藏输入中。
并且图像信息将与其他信息一起发送。
