获取多输入PHP的输入名称

Question

我很难搞清楚这一点。如何将来自不同输入的不同图像放入不同的文件目录中。

例如我想要“$ _FILES ['ma'];”去销售/ ma/xxxxxxx.jpg和“$ _FILES ['ny'];”去销售/ ny/xxxxxxx.jpg，我怎么做到这一点。

非常感谢你的任何帮助。

这是我非常简单的HTML

<form action="includes/upload.php" method="post" enctype="multipart/form-data"> 
    <label for="ma">ma</label> 
    <input type="file" name="ma" id="ma" multiple=""> 
    <label for="ma">ny</label> 
    <input type="file" name="ny" id="ny" multiple=""> 
    <label for="ma">nj</label> 
    <input type="file" name="nj" id="nj" multiple=""> 
    <label for="va">va</label> 
    <input type="file" name="va" id="va" multiple=""> 
    <input type="submit" value="Upload Image" name="submit"> 
</form> 

，这里是PHP。

<?php   
    $ma_file = $_FILES['ma']; 
    $ny_file = $_FILES['ny']; 
    $nj_file = $_FILES['nj']; 
    $va_file = $_FILES['va']; 

    $all_files = array($ma_file,$ny_file,$nj_file,$va_file); 

    foreach($all_files as $file) { 

     try { 
      if (
       !isset($file['error']) || 
       is_array($file['error']) 
      ) { 
       throw new RuntimeException('Invalid parameters.'); 
      } 

      // Check $_FILES['upfile']['error'] value. 
      switch ($file['error']) { 
       case "0": 
        break; 
       case UPLOAD_ERR_NO_FILE: 
        // throw new RuntimeException('No file sent.'); 
        // it's ok to have no file. 
        break; 
       case UPLOAD_ERR_INI_SIZE: 
       case UPLOAD_ERR_FORM_SIZE: 
        throw new RuntimeException('Exceeded filesize limit.'); 
       default: 
        throw new RuntimeException('Unknown errors.'); 
      } 

      if ($file['size'] > 1000000) { // under one mb. 
       throw new RuntimeException('Exceeded filesize limit.'); 
      } 

      $finfo = new finfo(FILEINFO_MIME_TYPE); 

      if (false === $ext = array_search(
       $finfo->file($file['tmp_name']), 
       array(
        'jpg' => 'image/jpeg', 
        'png' => 'image/png', 
        'gif' => 'image/gif', 
       ), 
       true 
      )) { 
       throw new RuntimeException('Invalid file format.'); 
      } 

      if (!move_uploaded_file(
       $file['tmp_name'], 
       sprintf('../sale/%s.%s', 
        sha1_file($file['tmp_name']),$ext 
       ) 
      )) { 
       throw new RuntimeException('Failed to move uploaded file.'); 
      } 



     } 
     catch (RuntimeException $e) { 
      echo $e->getMessage(); 
     } 
    } 
?>

合并$ _FILES有什么意义？

foreach($_FILES as $code => $subfiles) { 
        ^^^^^^^^ 
    ... $code will be ma/ny/nj/va 
    move_uploaded_files(.... "/some/path/$code/whatever/else"); 
}
