php - 如何在codeigniter中重置方法

问题描述

我有一个同时上传许多文件和图像的表单。问题是这种方法

$this->upload->display_errors()

每次循环通过此方法时，它都会保存上一轮循环的错误

$error[$i]= "File error: ".$this->upload->display_errors();

例如，如果我上传了两个非法文件，它会显示这个

索引 0：不允许
文件 索引 1：不允许文件 不允许文件

那么如何重置此方法？ps：我尝试了reset()函数，但是没有用

更新 这是方法

          public function do_upload($product_id)
        {
            $error = array();

            if(isset($_FILES['files']['name'])&&!empty($_FILES['files']['name'][0])):

         for ($i=0; $i <count($_FILES['files']['name']) ; $i++) :


                $config['upload_path']          = './images/';
                $config['allowed_types']        = 'gif|jpg|png';
                $config['max_size']             = 1;



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





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

               if(!$this->upload->do_upload('files[]')){


 $error[$i]= "File name: ". $_FILES['files']['name'][$i] ." ". $this->upload->display_errors() ."<br>";

               }else{

              $files = $this->upload->data();

$data = array('file_name'=>$files['file_name'],'product_id'=>$product_id,'file_type'=>$files['file_type']);

               $this->Files_model->create_file($data);
               }





endfor;








  endif;
 return $error;
//end method
        }

解决方案

我们无法重置 $this->upload->do_upload();

但是我们可以像这样重新初始化

// first upload 
$this->config->load('upload');
-- Code to upload Here -- 

// Another file
$this->config->load('upload_other_files');
-- Code to upload Here --

或者您可以为每个文件定义多个配置数组，如下面的代码：

$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';

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

对于其他文件

$config2['upload_path'] = './uploads/';
$config2['allowed_types'] = 'gif|jpg|png';
$config2['max_size'] = '100';
$config2['max_width'] = '100';
$config2['max_height'] = '100';

$this->load->library('upload', $config2);

// Alternately you can set
$this->upload->initialize($config2);
