Question

我正在尝试使用单个浏览按钮上传多个文件，但我无法通过它获得成功。我试过类似查询中提到的建议。下面的代码只上传一个文件，我需要使用相同的浏览按钮上传多个文件。

知道代码中有什么问题吗？

<html>
<body>

<form enctype="multipart/form-data" action="uploadj.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile[]" type="file" multiple /><br />



  <p>

    <input type="submit" name="button" id="button" value="Submit">
  </p>

</form>


</html>
</body>

Php Code :


   <?php

$get_folder = $_POST['textfield'];
mkdir ("/opt/lampp/htdocs/test_upload/" . $get_folder, 0777);
echo "Analysis Directory created successfully";

$target_path = "$get_folder/";


for($i=0;$i < count($_FILES['uploadedfile']['name']);$i++){



$target_path = $target_path . basename( $_FILES['uploadedfile']['name'][$i]);


if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_path))
{
    echo "The file has been uploaded";

} else

{
  echo "There was an error uploading the file, please try again!";
}


}



?>

谢谢！

Answer 1

这是错误的：$ _FILES [＆＃39;上传文件＆＃39;] [0] [＆＃39;名称＆＃39;]

你应该这样做：$ _FILES [＆＃39;上传文件＆＃39;] [＆＃39;名称＆＃39;] [0]

我已更新此代码以支持多次上传。如果有效，请告诉我

     for($i=0;$i<count($_FILES['uploadedfile']['tmp_name']);$i++){
      $target_path = ""; //to clear the values on each loop//
      $target_path = basename( $_FILES['uploadedfile']['name'][$i]);
      move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_path);
     }

您遇到的一个错误是在定义之前使用$target_path。我指的是：

$target_path = $target_path . basename( $_FILES['uploadedfile'][0]['name']);

如果之前未定义，则不能在右侧使用$target_path。最重要的是，0处于错误的位置。它应该是$_FILES['uploadedfile']['name'][0]。

您可能遇到的其他错误：

php.ini
php.ini
网络服务器用户（通常是www-data或apache）无法写入文件夹

<强>更新

另一个错误，就是你只是在你的循环中附加$target_path这使得第二次迭代试图将之前的上传用作文件夹，这是不允许的。例如，如果我上传了foo.png和bar.jpg，则第二个目标路径将是/opt/lampp/htdocs/test_upload/foo.png/bar.png，这不是有效路径。

我会通过改变这一行在你的循环中解决这个问题：

$target_path = $target_path . basename( $_FILES['uploadedfile']['name'][$i]);

为：

 $target_file =  $target_path . basename( $_FILES['uploadedfile']['name'][$i]);

并改变：

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_path))

为：

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_file))

以下代码适用于我的服务器（Ubuntu Server上传文件夹属于www-data，权限为755）：

<?php if($_SERVER['REQUEST_METHOD'] != 'POST'):?>
<html>
<body>

<form enctype="multipart/form-data" action="index2.php" method="POST">
Choose a file to upload: <input name="uploadedfile[]" type="file" multiple /><br />



  <p>

    <input type="submit" name="button" id="button" value="Submit">
  </p>

</form>


</html>
</body>

<?php else: ?>

<?php

$target_path = "./videos/";


for($i=0;$i < count($_FILES['uploadedfile']['name']);$i++){



$target_file = $target_path . basename( $_FILES['uploadedfile']['name'][$i]);


if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_file))
{
    echo "The file has been uploaded";

} else

{
  echo "There was an error uploading the file, please try again!";
}


}
?>

<?php endif; ?>

FORM：

<form enctype="multipart/form-data" action="" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload: <input name="uploadedfile[]" type="file" multiple /><br />

 <p>
 <input type="submit" name="button" id="button" value="Submit">
 </p>

</form>

PHP代码：

 if(isset($_POST['button'])){
     $upload_folder = "./textfiles/";
     for($i=0;$i<count($_FILES['uploadedfile']['tmp_name']);$i++){
          $target_path = ""; //to clear the values on each loop//
          $target_path = $upload_folder.basename( $_FILES['uploadedfile']['name'][$i]);
          if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'][$i], $target_path))
             {
             //do your redirect
             }else {
                //do your redirect
             }
   }
  }

注意：php代码将放在表单的顶部！我已经测试了这段代码，它在我的结尾很有用：
