我正在尝试创建一个多图像上传器，我遇到了这个link。我对下面的代码感到困惑，链接是我必须有 2

$this->upload->do_upload(); 运行我的代码的函数或如何使用

$this->upload->initialize($config);在以下情况？

代码：

//Image Upload Function

$conceptOne = 'conceptOne';
$conceptTwo = 'conceptTwo';

$location = $_SERVER['DOCUMENT_ROOT'].'/_assets/quote/uploads/';

$folderName = $this->quote->getCompanyDetails()->companyName;
$folderName = str_replace(" ", "_", $folderName);
$folderName = strtolower($folderName);

if(!is_dir($location.$folderName))
{   
    mkdir($location.$folderName);
    chmod($location.$folderName, 0777);

    //Set File Settings 
    $config['upload_path'] = $location.$folderName; 
    $config['allowed_types'] = 'jpg|png|pdf'; 
    $config['file_name'] = $conceptOne;
    $config['remove_spaces'] = TRUE;
    $config['overwrite'] = TRUE;
    $config['max_size'] = '1024'; 
    $config['max_width'] = '1024'; 
    $config['max_height'] = '768'; 

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

    print_r($config);

    if(!$this->upload->do_upload($conceptOne)) { #= try upload
        $data['uploadError'] = array('uploadError' => $this->upload->display_errors()); #Error
        $this->load->view('layout', $data);
    } // Do upload
    else{
        $data = array('upload_data' => $this->upload->data($conceptOne));
    }// end else
}// end if folder

Answer 1

您需要一个循环来重新初始化文件上传库，以便您可以处理用户上传的其他一些图像。

假设用户上传了 2 张图片。那么这意味着您需要将初始化文件上传库并在该循环中执行文件上传的代码。

for ($i = 0; $i < 2; $i++)
{
     // Change the config here if necessary
     $this->upload->initialize($config);
     // Call do_upload() here
}

Kemal 是对的：您必须遍历您拥有的文件。我会把“概念”放在一个数组中，这样你就可以使用foreach：

// Load upload library without any configuration
$this->load->library('upload');

$concepts = array('conceptOne','conceptTwo');

$location = $_SERVER['DOCUMENT_ROOT'].'/_assets/quote/uploads/';

$folderName = $this->quote->getCompanyDetails()->companyName;
$folderName = str_replace(" ", "_", $folderName);
$folderName = strtolower($folderName);

if(!is_dir($location.$folderName))
{   
    mkdir($location.$folderName);
    chmod($location.$folderName, 0777);
}

$config['upload_path'] = $location.$folderName;
$config['allowed_types'] = 'jpg|png|pdf';
$config['remove_spaces'] = TRUE;
$config['overwrite'] = TRUE;
$config['max_size'] = '1024';
$config['max_width'] = '1024';
$config['max_height'] = '768';

// Upload 'concepts'
foreach($concepts as $concept)
{
    $config['file_name'] = $concept;
    $this->upload->initialize($config);
    $this->upload->do_upload($concept);
}

// Upload logo
$config['file_name'] = 'logo-filename.gif';
$this->upload->initialize($config);
$this->upload->do_upload('logo');
