多图像上传文件上传错误数量

Question

我喜欢用数组的帮助上传一些图像到目录。因此，我有这样的代码：

$allowedExtensions = array('jpg', 'jpeg', 'png', 'bmp', 'tiff', 'gif'); 
      $maxSize = 2097152; 
      $Dir = "a/b/c/d"; 
      $storageDir = "a/b/c/d/tmp_images"; 

      //Arrays 
      $errors2 = $output = array(); 


      if(!empty($_FILES['image'])){ 

      // Validation loop (I prefer for loops for this specific task) 
      for ($i = 0; isset($_FILES['image']['name'][$i]); $i++) { 

       $fileName = $_FILES['image']['name'][$i]; 
       $fileSize = $_FILES['image']['size'][$i]; 
       /*$fileErr = $_FILES['image']['error'][$i];*/ 
       $fileExt = strtolower(pathinfo($fileName, PATHINFO_EXTENSION)); 

       // Dateiendung überprüfen 
       if (!in_array($fileExt, $allowedExtensions)) { 
        $errors2[$fileName][] = "format $fileExt in $fileName is not accepted"; 
       } 

       // check filesize 
       if ($fileSize > $maxSize) { 
        $errors2[$fileName][] = "maxsize of 2MB exceeded"; 
       } 


      } 

      /*// Handle validation errors here 
      if (count($errors) > 0) { 
       echo "Fehler beim Upload des Bildmaterials:"; 
       echo ($errors); ->gibt "Array" aus 
      }*/ 


      if (is_dir($Dir)){ 
       mkdir($storageDir, 0755); 
      }else{ 
       mkdir($Dir, 0755); 
       mkdir($storageDir, 0755); 
      } 


      // Fileupload 
      for ($i = 0; isset($_FILES['image']['name'][$i]); $i++) { 

      // Get base info 
      $fileBase = basename($_FILES['image']['name'][$i]); 
      $fileName = pathinfo($fileBase, PATHINFO_FILENAME); 
      $fileExt = pathinfo($fileBase, PATHINFO_EXTENSION); 
      $fileTmp = $_FILES['image']['tmp_name'][$i]; 

      // Construct destination path 
      $fileDst = $storageDir.'/'.basename($_FILES['image']['name'][$i]); 
      for ($j = 0; file_exists($fileDst); $j++) { 
       $fileDst = "$storageDir/$fileName-$j.$fileExt"; 
      } 

      // Move the file 

      if (count($errors2) == 0) { 
       if (move_uploaded_file($fileTmp, $fileDst)) { 
            ... 
           } 
         } 

与代码的问题是以下内容：在上载与所接受结束它将回声出两个或多个文件的情况下：

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to access abc2.png in /a/b/xxx.php on line xxx 

这指的是线：

if (move_uploaded_file($fileTmp, $fileDst)) { 

此消息将显示除第一个以外的每张图片。所以我不知道我做错了什么。如果有人能够帮助我，我会非常感激。我真的很感激。非常感谢。

你的代码是非常similar我的答案在limiting the checking condition while uploading swf files

这是你应该如何实现这样的..

    return is_dir ($pathname) || mkdir ($pathname, $mode);

Answer 2

首先，我将命名上传的字段分隔。例如。命名第一个字段<input name="image_1" type="file" />和第二个<input name="image_2" type="file" />。然后你可以遍历数组$_FILES改为：

foreach($_FILES as $fileId => $file){ 
    //make sure it's a file you want (optional) 
    if(!preg_match("/^image\_\d+$/",$fileId){ 
     continue; 
    } 

    //the rest of your code from the for loop 
} 

其次，你需要确保你的表单的加密类型是multipart/form-data。

这有帮助吗？

Answer 3

你为什么要访问$_FILES超全局数组作为三维数组？

如果您想从<input type="file" name="image"/>上传文件的文件名，您所要做的只是$name = $_FILES[ 'image' ][ 'name' ]最后不需要[ $i ]。

您需要循环像这样在$ _FILES中的条目：

foreach ($_FILES as $inputName => $fileData) 
{ 
    // $inputName is be 'image` for the first input and so on, 
    // $fileData will be an array of the attributes [ 'name', 'tmp_name', ... ] 
} 

Answer 4

我不知道这是否可以为您解决，但你可以尝试将这些转换为“正常” $_FILES值。

$arr_files = @$_FILES['image']; 

$_FILES  = array(); 
foreach(array_keys($arr_files['name']) as $h) 
$_FILES["image_{$h}"] = array( 'name'  => $arr_files['name'][$h], 
            'type'  => $arr_files['type'][$h], 
            'tmp_name' => $arr_files['tmp_name'][$h], 
            'error'  => $arr_files['error'][$h], 
            'size'  => $arr_files['size'][$h]); 

然后像正常一样运行循环。
