在CodeIgniter中上傳多個文件

Question

在我的CodeIgniter項目中，我在項目創建期間上傳文件。這裏的上傳功能：

function uploadFiles(){ 

    $this->load->library('upload'); 
    $error = 0;  
    $projectName = $_POST['projectname']; 
    mkdir('./uploads/'.$projectName); 

    for($i=0; $i<count($_FILES); $i++) 
    { 

     $_FILES['userfile']['name'] = $_FILES['files']['name'][$i]; 
     $_FILES['userfile']['type'] = $_FILES['files']['type'][$i]; 
     $_FILES['userfile']['tmp_name'] = $_FILES['files']['tmp_name'][$i]; 
     $_FILES['userfile']['error']  = $_FILES['files']['error'][$i]; 
     $_FILES['userfile']['size'] = $_FILES['files']['size'][$i]; 

     $config['upload_path'] = './uploads/'.$projectName; 
     $config['allowed_types'] = 'xml|etl'; 
     $config['max_size']  = '0'; 
     $config['overwrite']  = TRUE; 

     $this->upload->initialize($config); 

     if($this->upload->do_upload()) 
     { 
     $error += 0; 
     }else{ 
     $error += 1; 
     } 
    } 

    if($error > 0){ return FALSE; }else{ return TRUE; } 

} 

我呼籲在create_project功能，此功能是這樣的：

public function create_project() { 
    $this->load->library('form_validation'); 

    $this->form_validation->set_rules('projectname', 'Project name', 'required'); 

    $this->form_validation->set_message('required', 'This is an obligatory field'); 

    if($this->form_validation->run() == FALSE) { 
     $this->load->view('project_creation_view'); 
    } else { 
     $this->load->model('Project_management_model'); 
     $this->Project_management_model->create_project(); 
     $this->uploadFiles(); 
    } 
} 

然而，這並不做任何事情。這些文件沒有被上傳。即使是空目錄也沒有被創建。有人能幫我找到錯誤嗎？

謝謝。

Answer 1

您可以上傳任意數量的文件..

$config['upload_path'] = 'upload/Main_category_product/'; 
$path=$config['upload_path']; 
$config['allowed_types'] = 'gif|jpg|jpeg|png'; 
$config['max_size'] = '1024'; 
$config['max_width'] = '1920'; 
$config['max_height'] = '1280'; 
$this->load->library('upload', $config); 

foreach ($_FILES as $fieldname => $fileObject) //fieldname is the form field name 
{ 
    if (!empty($fileObject['name'])) 
    { 
     $this->upload->initialize($config); 
     if (!$this->upload->do_upload($fieldname)) 
     { 
      $errors = $this->upload->display_errors(); 
      flashMsg($errors); 
     } 
     else 
     { 
      // Code After Files Upload Success GOES HERE 
     } 
    } 
}

我想你錯過了這一點：

 
$config['file_name']  = 'somename_'.$i; 
$config['upload_path'] = './uploads/'.$projectName; 
...

這是我修改上傳多個文件，只是這個複製到MY_Upload.php文件CI_Upload類的擴展。它也使目錄。

然後，所有你需要在控制器功能做的是安排您的文件到一個數組，其中字段的名稱和關鍵是數組鍵和配置是數據。在你的情況下是這樣的：

$project_files['files'][0] = array(
      'upload_path' => './uploads/'.$projectName.'/', 
      'max_size' => 0, 
      'allowed_types' => 'xml|etl', 
      'overwrite' => TRUE, 
      'remove_spaces' => TRUE, 
     ); 
$project_files['files'][1] = array(
      'upload_path' => './uploads/'.$projectName.'/', 
      'max_size' => 0, 
      'allowed_types' => 'xml|etl', 
      'overwrite' => TRUE, 
      'remove_spaces' => TRUE, 
     ); 

如果所有文件的configs是一樣的只是做一個for循環來設置的，它也將採取「命名的鍵」，即。 $project_files['files']['file_key']。

然後只要致電：

if($this->upload->upload_files($project_files)){/*all files uploaded successfully*/}

思想我之前看到這個完全相同的問題在這裏;）

嘗試輸出$這個 - > upload->的display_errors（）你在哪裏遞增$錯誤變量。那會告訴你究竟出了什麼問題。我的錢是在權限...

Answer 5

我修改立方眼的MY_upload返回上傳的所有文件的文件信息。就像這樣，調用data方法時只能訪問最後一個文件的信息。我還將上傳器的IP地址添加到該列表中。

http://pastebin.com/tG8A85gY

它可以通過下面的被利用：

$upload_files = $this->upload->upload_files($project_files); 
if ($upload_files->status == true) 
{ 
$fileInfo = $uploaded_files->file_info; 
} 

我意識到這將是更好的編輯到立方眼睛，但是這是我的第一篇文章，我沒有信譽。

爲了簡單起見，我創建了這個CI幫助文件。您可以從配置文件&中加載它在項目中的任何位置使用。它只是需要3個patrameters

@fileobject = HTML文件對象的名稱

@fileopath =您要的文件路徑上傳

@filetypes =默認*，EX-「JPG | PNG | MP4 | pdf'

function fileUploader($fileobject, $filepath = "uploads/", $filetypes = "*"){ 
// retrieve the number of images uploaded; 
$number_of_files = sizeof($_FILES[$fileobject]['tmp_name']); 

// considering that do_upload() accepts single files, we will have to do a small hack so that we can upload multiple files. For this we will have to keep the data of uploaded files in a variable, and redo the $_FILE. 
$files = $_FILES[$fileobject]; 

$errors = array(); 
$file_arr = array(); 
$result = array(); 

// first make sure that there is no error in uploading the files 
for ($k = 0; $k < $number_of_files; $k++) { 
    if ($_FILES[$fileobject]['error'][$k] != 0) $errors[$k][] = 'Couldn\'t upload file ' . $_FILES[$fileobject]['name'][$k]; 
} 
if (sizeof($errors) == 0) { 
    // now, taking into account that there can be more than one file, for each file we will have to do the upload 
    // we first load the upload library 
    $CI =& get_instance(); 

    $CI->load->library('upload'); // load library 

    // next we pass the upload path for the images 
    $config['upload_path'] = FCPATH . $filepath; 
    // also, we make sure we allow only certain type of images 
    $config['allowed_types'] = $filetypes; 
    //$config['max_size'] = (int)(ini_get('upload_max_filesize')); 
    $config['max_size'] = '10000'; 
    $config['overwrite'] = FALSE; 

    for ($i = 0; $i < $number_of_files; $i++) { 
     $_FILES['uploadedimage']['name'] = $files['name'][$i]; 
     $_FILES['uploadedimage']['type'] = $files['type'][$i]; 
     $_FILES['uploadedimage']['tmp_name'] = $files['tmp_name'][$i]; 
     $_FILES['uploadedimage']['error'] = $files['error'][$i]; 
     $_FILES['uploadedimage']['size'] = $files['size'][$i]; 
     //now we initialize the upload library 
     $CI->upload->initialize($config); 
     // we retrieve the number of files that were uploaded 
     if ($CI->upload->do_upload('uploadedimage')) { 
      $imageup = $CI->upload->data(); 
      // print_r($imageup["orig_name"]);die; 
      array_push($file_arr, $imageup["orig_name"]); 
      $result["response"] = "true"; 
      $result["message"] = "Files uploaded successfully."; 
      $result["files"] = $file_arr; 

     } else { 
      $result["response"] = "false"; 
      $result["message"][$i] = $CI->upload->display_errors(); 
     } 
    } 

} else { 
    $result["response"] = "false"; 
    $result["message"] = $errors; 

} 
return $result;} 

測試&已被證實。

由於我的聲望級別，我還不能評論，但Zoom在接受的關於$ fieldname變量的答案下做了一個評論，該變量是導致錯誤的數組。我對該答案有同樣的問題，並發現這是因爲我用[]將所有文件輸入名稱附加在表單上，​​這使得php以數組變量的形式提取這些輸入。要解決該問題，只需爲每個文件輸入一個唯一的名稱，而不是使其成爲一個PHP數組。我這樣做後，這個問題對我來說就消失了，接受的答案就像一個魅力。只是以爲我會把這些信息一起傳給那些在這個問題上磕磕絆絆的人。
