嗨，我是 codeigniter 的新手，你能帮我在 codeigniter 中插入多个文件（文档和图像）吗？这是我的示例代码

看法：

<label>Picture</label>
            <input type="file" name="userfile" size="100" /> 

<label>Document</label>
           <input type="file" name="documentfile" size="10" />

控制器：

 $m = $_FILES['userfile']['name'];
 $n = $_FILES['documentfile']['name'];
  if ($m !== "")
        {
            $config['upload_path'] = './upload_images/';
            $config['allowed_types'] = 'jpg|png|jpeg|gif';
            $config['max_size'] = '0'; // 0 = no file size limit
            $config['max_width']  = '0';
            $config['max_height']  = '0';
            $config['overwrite'] = TRUE;
            $this->load->library('upload', $config);
             $this->upload->do_upload();
             $upload_result = $this->upload->data();
        }
       elseif ($n !== "")
        {
            $config_document['upload_path'] = './upload_documents/';
            $config_document['allowed_types'] = 'pdf';
            $config_document['max_size'] = '0';
            $config_document['overwrite'] = TRUE;
            $this->load->library('upload', $config_document);
             $this->upload->do_upload();
             $upload_result2 = $this->upload->data();
        }   
 $image_filename = $upload_result['file_name'];
 $docu_filename = $upload_result2['file_name '];
$this->MODEL->add_asset($image_filename, $docu_filename);

我试图回显两个文件名并且它有效，但我的 $docu_filename 生成 NULL 值；请帮忙。谢谢你

您好，只需检查上传文件的文件扩展名并据此进行设置即可。您还必须设置 html 表单 enctype 的另一件事。检查以下示例

表单视图

<form method="post" action="controller" enctype="multipart/form-data"> 
    <input type="file" name="test">
    <input type="submit" value="submit" />
</form>

在控制器中

 $path = $_FILES['test']['name'];
 $ext = pathinfo($path, PATHINFO_EXTENSION);
 $img_ext_chk = array('jpg','png','gif','jpeg');
 $doc_ext_chk = array('pdf','doc');

if (in_array($ext,$img_ext_chk))
        {
            $config['upload_path'] = './upload_images/';
            $config['allowed_types'] = 'jpg|png|jpeg|gif';
            $config['max_size'] = '0'; // 0 = no file size limit
            $config['max_width']  = '0';
            $config['max_height']  = '0';
            $config['overwrite'] = TRUE;
            $this->load->library('upload', $config);
             $this->upload->do_upload();
             $upload_result = $this->upload->data();
        }
       elseif (in_array($ext,$doc_ext_chk))
        {
            $config_document['upload_path'] = './upload_documents/';
            $config_document['allowed_types'] = 'pdf';
            $config_document['max_size'] = '0';
            $config_document['overwrite'] = TRUE;
            $this->load->library('upload', $config_document);
             $this->upload->do_upload();
             $upload_result2 = $this->upload->data();
        }
