所以我搜索了很多类似的问题，但似乎无法找到解决方案。
我有联系表单，我希望它能够发送多个图像。我现在的代码有三个输入字段用于图片，但现在我只想出了如何获取其中一个图片上传和发送。我很确定我需要某种循环或数组，但这不是我的强项。

答案 0 :(得分：1)
您的所有三个字段都被命名为＆＃34;附件＆＃34;。给他们一个独特的名字，如＆＃34; attachment1＆＃34;，＆＃34; attachment2＆＃34;等。
然后在上传时使用此功能：
for ($x = 1; $x <= $numberOfFiles; ++$x) {
$tmpName = $_FILES['attachment'.$x]['tmp_name'];
$fileType = $_FILES['attachment'.$x]['type'];
$fileName = $_FILES['attachment'.$x]['name'];
// do your upload here
}
你甚至可以在这样的循环中完成它，只要你保持命名模式一致，就可以在不改变后端代码的情况下添加更多文件字段（可能使用JavaScript）。
$x = 1;
while (isset($_FILES['attachment'.$x])) {
$tmpName = $_FILES['attachment'.$x]['tmp_name'];
$fileType = $_FILES['attachment'.$x]['type'];
$fileName = $_FILES['attachment'.$x]['name'];
// do your upload here
++$x;
}
这只会在每个周期增加x，并检查是否使用该名称发送了一个文件。
在某人用收件箱填充大量文件和/或网络恶意之前，您可能还应该检查一些文件的大小和类型。
更新：这应该是一个基本上完整的解决方案。我目前无法为您测试它，所以它可能无法直接开箱即用，但它至少应该指向正确的方向。在此代码段中，它首先设置电子邮件的初始部分，然后循环并一次添加一个文件。
