arrays - 使用CodeIgniter 2.0上传多个文件(数组)

转载作者：行者123 更新时间：2023-12-03 09:13:15

我已经进行了3天的搜索和苦苦挣扎，但仍无法完成。
我想要做的是使用多个文件输入表单，然后上传它们。我不能只使用固定数量的文件进行上传。我在StackOverflow上尝试了许多解决方案，但找不到有效的解决方案。

这是我的上传 Controller

<?php

class Upload extends CI_Controller {

function __construct()
{
    parent::__construct();
    $this->load->helper(array('form', 'url','html'));
}

function index()
{    
    $this->load->view('pages/uploadform', array('error' => ' ' ));
}

function do_upload()
{
    $config['upload_path'] = './Images/';
    $config['allowed_types'] = 'gif|jpg|png';


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

 foreach($_FILES['userfile'] as $key => $value)
    {

        if( ! empty($key['name']))
        {

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

            if ( ! $this->upload->do_upload($key))
            {
                $error['error'] = $this->upload->display_errors();

                $this->load->view('pages/uploadform', $error);
            }    
            else
            {
                $data[$key] = array('upload_data' => $this->upload->data());

                $this->load->view('pages/uploadsuccess', $data[$key]);


            }
         }

    }    
  }    
 }
 ?>

我的上传表单是This。

 <html>
 <head>
    <title>Upload Form</title>
</head>
<body>

<?php echo $error;?>

<?php echo form_open_multipart('upload/do_upload');?>

<input type="file" multiple name="userfile[]" size="20" />
<br /><br />


<input type="submit" value="upload" />

</form>

</body>
</html>

我只是一直有这个错误:

You did not select a file to upload.

这是示例的数组:

Array ( [userfile] => Array ( [name] => Array ( [0] => youtube.png [1] => zergling.jpg ) [type] => Array ( [0] => image/png [1] => image/jpeg ) [tmp_name] => Array ( [0] => E:\wamp\tmp\php7AC2.tmp [1] => E:\wamp\tmp\php7AC3.tmp ) [error] => Array ( [0] => 0 [1] => 0 ) [size] => Array ( [0] => 35266 [1] => 186448 ) ) )

如果我选择2个文件，我会连续5次这样做。
我还使用标准的上传库。

最佳答案

我终于设法在您的帮助下使其正常运行!

这是我的代码:

 function do_upload()
{       
    $this->load->library('upload');

    $files = $_FILES;
    $cpt = count($_FILES['userfile']['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES['userfile']['name']= $files['userfile']['name'][$i];
        $_FILES['userfile']['type']= $files['userfile']['type'][$i];
        $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
        $_FILES['userfile']['error']= $files['userfile']['error'][$i];
        $_FILES['userfile']['size']= $files['userfile']['size'][$i];    

        $this->upload->initialize($this->set_upload_options());
        $this->upload->do_upload();
    }
}

private function set_upload_options()
{   
    //upload an image options
    $config = array();
    $config['upload_path'] = './Images/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size']      = '0';
    $config['overwrite']     = FALSE;

    return $config;
}
