如何在圖片上傳功能中提供動態路徑？

我想用PHP將圖像上傳到各自的文件夾。共有6個文件夾和2個文件夾都有子文件夾。我創建了一個包含文件夾和子文件夾列表的下拉列表。現在我可以創建縮略圖，但無法將原始圖像存儲在相應的文件夾中。我如何在函數中編寫動態路徑？如何在圖片上傳功能中提供動態路徑？

我想用下面的動態路徑：

$target_folder = "images/website/". $_POST["path"]."/";

，但我得到的錯誤了這條道路。

下面是cwUpload函數的以下代碼。

<?php 
function cwUpload($field_name = '', $target_folder = '', $file_name = '', $thumb = FALSE, $thumb_folder = '', $thumb_width = '', $thumb_height = ''){ 
//folder path setup 
$target_path = $target_folder; 
$thumb_path = $thumb_folder; 

//file name setup 
$filename_err = explode(".",$_FILES[$field_name]['name']); 
$filename_err_count = count($filename_err); 
$file_ext = $filename_err[$filename_err_count-1]; 
if($file_name != '') 
{ 
    $fileName = $file_name.'.'.$file_ext; 
} 
else 
{ 
    $fileName = $_FILES[$field_name]['name']; 
} 

//upload image path 
$upload_image = $target_path.basename($fileName); 

//upload image 
if(move_uploaded_file($_FILES[$field_name]['tmp_name'],$upload_image)) 
{ 
    //thumbnail creation 
    if($thumb == TRUE) 
    { 
     $thumbnail = $thumb_path.$fileName; 
     list($width,$height) = getimagesize($upload_image); 
     $thumb_create = imagecreatetruecolor($thumb_width,$thumb_height); 
     switch($file_ext){ 
      case 'jpg': 
       $source = imagecreatefromjpeg($upload_image); 
       break; 
      case 'jpeg': 
       $source = imagecreatefromjpeg($upload_image); 
       break; 
      case 'png': 
       $source = imagecreatefrompng($upload_image); 
       break; 
      case 'gif': 
       $source = imagecreatefromgif($upload_image); 
       break; 
      default: 
       $source = imagecreatefromjpeg($upload_image); 
     } 
     imagecopyresized($thumb_create,$source,0,0,0,0,$thumb_width,$thumb_height,$width,$height); 
     switch($file_ext){ 
      case 'jpg' || 'jpeg': 
       imagejpeg($thumb_create,$thumbnail,100); 
       break; 
      case 'png': 
       imagepng($thumb_create,$thumbnail,100); 
       break; 
      case 'gif': 
       imagegif($thumb_create,$thumbnail,100); 
       break; 
      default: 
       imagejpeg($thumb_create,$thumbnail,100); 
     } 
    } 

    return $fileName; 
} 
else 
{ 
    return false; 
} 
} 
    if(!empty($_FILES['fileToUpload']['name'])){ 

//call thumbnail creation function and store thumbnail name 
$upload_img = cwUpload('fileToUpload','images/','',TRUE,'images/thumbs/','200','160'); 

//full path of the thumbnail image 
$thumb_src = 'images/thumbs/'.$upload_img; 

//set success and error messages 
$message = $upload_img?"<span style='color:#008000;'>Image thumbnail have been created successfully.</span>":"<span style='color:#F00000;'>Some error occurred, please try again.</span>"; 

    }else{  
    `//if form is not submitted, below variable should be blank 
    $thumb_src = ''; 
     $message = ''; 
    } 
    ?>

之前只需創建一個目標文件夾，請檢查相應的文件夾 – Elby

的權限，請添加一些明智的代碼縮進 – RiggsFolly

@Elby我檢查的權限。當我嘗試直接上傳圖片而不創建縮略圖時，我可以添加圖片。我只需要$ target_folder部分中的一個正確路徑 – HebleV

您需要創建一個動態目錄來做到這一點。一個 move_uploaded_file

mkdir("images/website/'. $_POST[path].'"); 
$target_folder = "images/website/". $_POST['path']."/";

創建了Asusual縮略圖，但出現此錯誤Warning：mkdir（）：Invalid argument in – HebleV

如何在圖片上傳功能中提供動態路徑？
