Question

我通过phpmailer发送带有多个附件的电子邮件。我用来发送多个附件的循环是带附件的消息，只包含最后选择的文件，并且不发送前两个或一个文件。 Loop有问题吗？请：

     foreach($_FILES as $key => $file){
    $target_path = "uploads/";
    $target_path = $target_path .basename($file['name']);

   if(move_uploaded_file($file['tmp_name'], $target_path)) {
   echo "the file ".basename($file['name'])." has been uploaded";
   }else {
  echo "there was an error";
   }
  mail->AddAttachment($target_path);
   }

     <form id=
       "mail" name="mail" method="POST" action="<?php $PHP_SELF ?>" 
    enctype="multipart/form-data">
     <input type="file" name="uploaded" multiple="" />
    <input name="Submit1" type="submit" value="Submit"  />
    </form>

Answer 1

将[]添加到输入字段的名称中，如下所示：

<input type="file" name="uploaded[]" multiple="" />

每个文件使用相同的名称“上传”，因此“上传”将被处理的每个连续文件替换。通过添加括号，每个连续文件都会添加到“已上载”数组中。这是添加$_FILES后我得到的[]数组：

Array
(
  [uploaded] => Array
    (
      [name] => Array
        (
          [0] => file4.txt
          [1] => file1.txt
          [2] => file2.txt
          [3] => file3.txt
        )

      [type] => Array
        (
          [0] => text/plain
          [1] => text/plain
          [2] => text/plain
          [3] => text/plain
        )

      [tmp_name] => Array
        (
          [0] => C:\temp\php95.tmp
          [1] => C:\temp\php96.tmp
          [2] => C:\temp\php97.tmp
          [3] => C:\temp\php98.tmp
        )

      [error] => Array
        (
          [0] => 0
          [1] => 0
          [2] => 0
          [3] => 0
        )

      [size] => Array
        (
          [0] => 7
          [1] => 2850
          [2] => 27
          [3] => 231
        )
    )
)

每个数组中的索引0是一个文件，每个数组中的索引1是下一个文件，依此类推。

这也是你如何获得同名的多个复选框的值。（有关示例，请参阅this comment。

以下是循环上传文件的方法。

// first get the count of how many files are uploaded
$numFiles = count(array_filter($_FILES['uploaded']['name']));

for ($i = 0; $i < $numFiles; ++$i) {
    $target_path = 'c:/temp/' . basename($_FILES['uploaded']['name'][$i]);
    if(move_uploaded_file($_FILES['uploaded']['tmp_name'][$i], $target_path)) {
        echo "the file ".basename($_FILES['uploaded']['name'][$i])." has been uploaded<br />";
    }
}

注意我如何在$i循环中使用for来跟踪当前文件的索引。

（如果您想知道为什么我打电话给array_filter()来获取计数，如果您没有上传任何文件，它看起来就像一个空白条目。array_filter()删除该空白/无效条目。）

尝试通过循环在每次迭代中为每个文件添加一个唯一的数字，如下所示：

$counter = 0;
foreach($_FILES as $key => $file){
    $counter++;
    $target_path = "uploads/";
    $target_path = $target_path .basename($file['name'], ".jpg") . $counter . ".jpg";



if(move_uploaded_file($file['tmp_name'], $target_path)) {
   echo "the file ".basename($file['name'])." has been uploaded";
   }else {
  echo "there was an error";
   }
  mail->AddAttachment($target_path);
   }

 <form id=
   "mail" name="mail" method="POST" action="<?php $PHP_SELF ?>" 
enctype="multipart/form-data">
 <input type="file" name="uploaded" multiple="" />
<input name="Submit1" type="submit" value="Submit"  />

仅通过phpmailer附加第三个文件
