我正在尝试让表单跳过文件代码和检查我被告知使用：iF($_FILES["fileToUpload"] == UPLOAD_ERR_NO_FILE) {
我试图在我的代码中实现这一点，但我是 php 的新手，我想我可能搞砸了标题。现在，当我发送不带附件的电子邮件时，它会跳过所有文件检查。
我已经评论了我尝试跳过代码的行。
如果我没有提供足够的信息详细信息，请告诉我。

您已经在需要时添加了条件。
只需将条件替换为
if(isset($_FILES["fileToUpload"]) && !empty($_FILES["fileToUpload"]["tmp_path"])){
// your code here
}
您可以使用 is_uploaded_file（）：
if(!file_exists($_FILES['myfile']['tmp_name']) || !is_uploaded_file($_FILES['myfile']['tmp_name'])) {
echo 'No upload';
}
