允许用户附加多个文件，但可选

Question

我想允许用户在我的表单中附加多个文件，并且这些文件作为电子邮件中的附件发给我。但是我希望保持这种可选方式，即如果用户附加文件，则文件将作为附件发送，如果用户未附加文件，则表单的其余部分将出现在电子邮件中。

有人可以帮助我吗？

我是新来的PHP所以下面是我的PHP文件。

<?php

Answer 1

如果用户没有选择一个文件附件，您可以通过大小或临时名称检查：如果没有选择上传的文件的形式

，PHP将返回 $ _FILES ['userfile'] ['size']为0，$ _FILES ['userfile'] ['tmp_name'] 为空。

从http://php.net/manual/en/features.file-upload.post-method.php

，而不是打电话$mail->AddAttachment，但是从你的代码，你已经这样做，所以我不知道如果我理解你的问题，或者你可能需要解释一下多一点。

Answer 2

首先，你的表格看起来应该是这样的：

<form method="POST" enctype="multipart/form-data"> 
    <input type="file" name="fileToUpload[]" id="fileToUpload[]" multiple> 
    <input type="submit" value="upload version" /> 
</form> 

然后你可以使用PHP然后通过上传的文件循环。

if(isset($_FILES['fileToUpload']){ 
    if(!empty($_FILES['fileToUpload']['tmp_name']) && !empty($_FILES['fileToUpload']['name'])) { 
    foreach($_FILES['fileToUpload']['tmp_name'] as $key => $value) 
    $mail->AddAttachment($_FILES['fileToUpload']['tmp_name'][$key], $_FILES['fileToUpload']['name'][$key]); 
    } 
} 

当然，您需要应用相同的foreach，对于您在上载文件中进行的所有检查。

感谢你们所有的专家，特别是Rajapandian，Joel，NogDog等，他们帮了我很多。最后我的问题解决了。现在文件附件对用户是可选的。如果他附上档案，表格会附上附件，如果他没有附上档案，表格会以邮件附上而不附上。我与大家分享这个脚本。这里是PHP。再一次感谢所有人。

if (!empty($_FILES['fileToUpload']['tmp_name']) && !empty($_FILES['fileToUpload']['name'])) { 
     foreach ($_FILES['fileToUpload']['tmp_name'] as $key => $value) { 
      // added this IF block: 
      if (file_exists($_FILES['fileToUpload']['tmp_name'][$key])) { 
       $mail->AddAttachment($_FILES['fileToUpload']['tmp_name'][$key], $_FILES['fileToUpload']['name'][$key]); 
      } 
     } 
    }
