Question

我现在一直在努力寻找并努力工作3天，但我不能。我想要做的是使用多文件输入表单，然后上传它们。我不能只使用固定数量的文件上传。我在StackOverflow上尝试了很多解决方案，但我找不到工作的解决方案。

这是我的上传控制器

<?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。

 <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>

我一直有这个错误：

您没有选择要上传的文件。

以下是示例的数组：

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

如果我选择2个文件，我会连续5次这样做。我也使用标准的上传库。

Answer 1

我终于设法让它在你的帮助下工作了！

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;
}

谢谢你们！

Answer 2

您应该使用此库在CI https://github.com/stvnthomas/CodeIgniter-Multi-Upload

中进行多重上传

安装只需将MY_Upload.php文件复制到应用程序库目录即可。

使用：控制器中的函数test_up

public function test_up(){
if($this->input->post('submit')){
    $path = './public/test_upload/';
    $this->load->library('upload');
    $this->upload->initialize(array(
        "upload_path"=>$path,
        "allowed_types"=>"*"
    ));
    if($this->upload->do_multi_upload("myfile")){
        echo '<pre>';
        print_r($this->upload->get_multi_upload_data());
        echo '</pre>';
    }
}else{
    $this->load->view('test/upload_view');
}

}

在applications / view / test文件夹中的upload_view.php

<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="myfile[]" id="myfile" multiple>
<input type="submit" name="submit" id="submit" value="submit"/>

Answer 3

试试这段代码。

它对我来说很好用

每次都要初始化库

    function do_upload()
    {
        foreach ($_FILES as $index => $value)
        {
            if ($value['name'] != '')
            {
                $this->load->library('upload');
                $this->upload->initialize($this->set_upload_options());

                //upload the image
                if ( ! $this->upload->do_upload($index))
                {
                    $error['upload_error'] = $this->upload->display_errors("<span class='error'>", "</span>");

                    //load the view and the layout
                    $this->load->view('pages/uploadform', $error);

                    return FALSE;
                }
                else
                {

                     $data[$key] = array('upload_data' => $this->upload->data());

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


                }
            }
        }

    }

    private function set_upload_options()
    {   
        //upload an image options
        $config = array();
        $config['upload_path'] = 'your upload path';
        $config['allowed_types'] = 'gif|jpg|png';

        return $config;
    }

进一步修改

我找到了必须使用一个唯一输入框上传文件的方式

CodeIgniter不支持多个文件。在foreach中使用do_upload（）与在外部使用它不同。

您需要在没有CodeIgniter帮助的情况下处理它。这是一个例子https://github.com/woxxy/FoOlSlide/blob/master/application/controllers/admin/series.php#L331-370

https://stackoverflow.com/a/9846065/1171049

这就是你在交流中说的那样：）

Carlos Rincones建议;不要害怕和超级球员一起比赛。

$files = $_FILES;

for($i=0; $i<count($files['userfile']['name']); $i++)
{
    $_FILES = array();
    foreach( $files['userfile'] as $k=>$v )
    {
        $_FILES['userfile'][$k] = $v[$i];                
    }

    $this->upload->do_upload('userfile')
}

我在自定义库中使用了以下代码从我的控制器中拨打，如下所示，

function __construct() {<br />
   &nbsp;&nbsp;&nbsp; parent::__construct();<br />
   &nbsp;&nbsp;&nbsp;   $this->load->library('CommonMethods');<br />
}<br />

$config = array();<br />
$config['upload_path'] = 'assets/upload/images/';<br />
$config['allowed_types'] = 'gif|jpg|png|jpeg';<br />
$config['max_width'] = 150;<br />
$config['max_height'] = 150;<br />
$config['encrypt_name'] = TRUE;<br />
$config['overwrite'] = FALSE;<br />

// upload multiplefiles<br />
$fileUploadResponse = $this->commonmethods->do_upload_multiple_files('profile_picture', $config);

/**
 * do_upload_multiple_files - Multiple Methods
 * @param type $fieldName
 * @param type $options
 * @return type
 */
public function do_upload_multiple_files($fieldName, $options) {

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

        $this->CI->load->library('upload');
        $this->CI->upload->initialize($options);

        //upload the image
        if (!$this->CI->upload->do_upload($fieldName)) {
            $response['erros'][] = $this->CI->upload->display_errors();
        } else {
            $response['result'][] = $this->CI->upload->data();
        }
    }

    return $response;
}

Answer 10

所有已发布的文件都将出现在$ _FILES变量中，对于使用codeigniter上传库，我们需要提供我们用于上传的field_name（默认情况下它将是＆＃39; userfile＆＃39;），所以我们得到所有发布的文件并创建另一个文件数组，为每个文件创建我们自己的名称，并将此名称赋予codeigniter库do_upload函数。

public String setRedirectURL(){
    return "/redirect/" + this.statusQueryToken;
}

@RequestMapping( /* This should be the return-value of setRedirectURL */)
public URL getRedirectURL(){

codeigniter中没有预定义的方法可以一次上传多个文件，但您可以将数据发送到数组并逐个上传

这里是参考：这是在codeigniter 3.0.1中使用预览https://codeaskbuzz.com/how-to-upload-multiple-file-in-codeigniter-framework/

对我有用。

保存，然后将变量$ _FILES重新定义为您需要的任何内容。也许不是最好的解决方案，但这对我有用。

function do_upload()
{

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

    $quantFiles = count($_FILES['userfile']['name']);


    for($i = 0; $i < $quantFiles ; $i++)
    {
        $arquivo[$i] = array
                    (
                        'userfile' => array 
                                        (
                                            'name' => $_FILES['userfile']['name'][$i],
                                            'type' => $_FILES['userfile']['type'][$i],
                                            'tmp_name' => $_FILES['userfile']['tmp_name'][$i],
                                            'error' => $_FILES['userfile']['error'][$i],
                                            'size' => $_FILES['userfile']['size'][$i]
                                        )
                    );
    }


    for($i = 0; $i < $quantFiles ; $i++)
    {
        $_FILES = '';
        $_FILES = $arquivo[$i];



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


            return FALSE;
        }
        else
        {

            $data[$i] = array('upload_data' => $this->upload->data());

            var_dump($this->upload->data());
        }


    }





    if(isset($error))
        {
            $this->index($error);
        }
        else
        {
            $this->index($data);
        }

}

建立配置的单独函数..

private function set_upload_options()
{   
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'xml|pdf';
    $config['max_size'] = '10000';

    return $config;
}

我最近在研究它。试试这个功能：

/**
 * @return array an array of your files uploaded.
 */
private function _upload_files($field='userfile'){
    $files = array();
    foreach( $_FILES[$field] as $key => $all )
        foreach( $all as $i => $val )
            $files[$i][$key] = $val;

    $files_uploaded = array();
    for ($i=0; $i < count($files); $i++) { 
        $_FILES[$field] = $files[$i];
        if ($this->upload->do_upload($field))
            $files_uploaded[$i] = $this->upload->data($files);
        else
            $files_uploaded[$i] = null;
    }
    return $files_uploaded;
}

在你的情况下：

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

或

<input type="file" name="images[]">
<input type="file" name="images[]">
<input type="file" name="images[]">

在控制器中：

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

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

    if ($_FILES['images']) {
        $images= $this->_upload_files('images');
        print_r($images);
    }
}

PHP手册的一些基本参考：PHP file upload

使用CodeIgniter 2.0上传多个文件（Array）
