Javascript HTML/PHP文件上载状态
我是新手，在搜索的过程中，我可以找到我面临的问题。 我的问题是：我有这个表单，它应该上传文件，然后作为邮件发送。如何显示正在上载的文件的状态。因为，人们只是简单地提交表单，而不允许上传文件。 以下是我的php代码：Javascript HTML/PHP文件上载状态,javascript,php,html,forms,file-upload,Javascript,Php,Html,Forms,File Upload,我是新手，在搜索的过程中，我可以找到我面临的问题。 我的问题是：我有这个表单，它应该上传文件，然后作为邮件发送。如何显示正在上载的文件的状态。因为，人们只是简单地提交表单，而不允许上传文件。 以下是我的php代码： <?php if(isset($_POST['Email'])) { $to = "<<email id>>"; $fromEmail = $_POST['Email']; $fromName = $_POST['Na

我已经尝试了很多东西，但仍然不清楚。如果你想阻止发送没有附件的电子邮件，你应该更改“附件检查” 更改此行：
if(isset($_FILES['attachment']['tmp_name']))
有一个叫做Swift Mailer的库，它可以很好地处理这个问题亲爱的@Skynet，只需在许多帖子中添加标签，就可以获得这个小小的声誉，这就是所谓的垃圾邮件。。。请停止向随机问题添加标签。
if(!empty($_FILES['attachment']['tmp_name']))
