将上传的文件数据存储到数组中

Question

我有以下情况： 当用户单击时，我需要一次上传3个文件。还有的代码，我有我的观点：

<?php echo form_open_multipart('uploads/do_upload', 'class="dropzone", id="dropzone-prod", data-nextFormExecDropzone="#dropzone-promo"');?> 
    <div class="fallback"> 
    <input type="file" name="userfile" size="20" /> 
    </div> 
</form> 
<?php echo form_open_multipart('uploads/do_upload', 'class="dropzone", id="dropzone-promo", data-nextFormExecDropzone="#dropzone-plan"');?> 
    <div class="fallback"> 
    <input type="file" name="userfile" size="20" /> 
    </div> 
</form> 
<?php echo form_open_multipart('uploads/do_upload', 'class="dropzone", id="dropzone-plan"');?> 
    <div class="fallback"> 
    <input type="file" name="userfile" size="20" /> 
    </div> 
</form> 
<div class="col-lg-4"> 
    <button id="processQueue" class="btn btn-primary" type="button"><i class="fa fa-upload"></i>Start Upload</button> 
</div> 

当用户点击该按钮时，我有向各自形成我希望它的顺序JavaScript代码。 在我的控制，我有以下方法（do_upload（））：

function do_upload() { 
    //$filePath = $this->config->item('base_current_upload_url'); 
    $filePath = APPPATH.'UPLOADS/'; 
    $filePathAfterUploaded = $this->config->item('base_uploaded_url'); 

    $config['upload_path'] = $filePath; 
    $config['allowed_types'] = '*'; 
    $config['max_size'] = 1024 * 100; 

    $this->load->library('upload', $config); 

    //$this->load->library('csvreader'); 
    //$filePathAfterUploaded = $this->config->item('base_uploaded_url'); 
    //print_r($filePath); die(); 
    $basefilepath = APPPATH.'UPLOADS/'; 
    $this->load->model('uploads_m'); 

    if (! $this->upload->do_upload('file')) { 
     $error = array('error' => $this->upload->display_errors()); 

     print_r($error); 
    } 
    else { 
     $data = array('upload_data' => $this->upload->data()); 
     print_r($data); die(); 
    } 

}

问题：

我需要上传3个文件。如果只有一个失踪，我不能继续。 我这样做，函数do_upload被称为每个文件的上传过程中，所以我需要找到一种方法来确定3个文件上传。 （之后，我将使用mysql'load data infile'将这些文件中的数据加载到某些表中，但是如果这三个文件已上传，我只能这样做。 您能帮我找到一种方法来处理这种情况吗？

的$数据每次do_uplaod被称为的结构是这样的：

Array 
(
[upload_data] => Array 
    (
     [file_name] => PROMOWEB111120131.txt 
     [file_type] => text/plain 
     [file_path] => C:/Program Files/EasyPHP-DevServer-13.1VC9/data/localweb/projects/integration/www/application/UPLOADS/ 
     [full_path] => C:/Program Files/EasyPHP-DevServer-13.1VC9/data/localweb/projects/integration/www/application/UPLOADS/PROMOWEB111120131.txt 
     [raw_name] => PROMOWEB111120131 
     [orig_name] => PROMOWEB11112013.txt 
     [client_name] => PROMOWEB11112013.txt 
     [file_ext] => .txt 
     [file_size] => 2.67 
     [is_image] => 
     [image_width] => 
     [image_height] => 
     [image_type] => 
     [image_size_str] => 
    ) 

)

如果do_upload是一个独立的函数，然后引入计算呼叫的次数一个静态变量

function do_upload() { 
    static $count = 0; 
    // The rest of your function goes here 
    if (no_errors_occurred) { 
     static::$count++; 
    } 
    if ($count == 3) { 
     // This function has been called 3 times; trigger something here 
    } 
} 

更好但是，如果是这样在一个类...

class MyClass { 
    protected static $data = array(); 

    // Other functions and properties 

    public function do_upload() { 
     // The rest of your function 
     if (no_errors_occurred) { 
      static::$data[] = array (
       'upload_data' => array (
        'file_name' => ..., 
        // Populate the data array 
       ) 
      ); 
     } 
     $this->do_mysql_load_data_infile(); 
    } 

    protected function do_mysql_load_data_infile() { 
     if (count(static::$data) != 3) { 
      return false; 
     } 
     // Do MySQL load data infile 
     // Get information about file uploads by accessing the static::$data array 
     foreach (static::$data as $file) { 
      echo $file['upload_data']['file_name']; 
     } 
    } 
}
