Question

我尝试同时在CodeIgniter中上传视频和图片，但只上传了图片... 我的HTML：

<form method="post" enctype="multipart/form-data" action="{$BASE_URL}multimedia/save" >
   <b>Image</b><br/>
   <input type="file" name="userfile" id="userfile"><br><br/>
   <b>Video</b><br/>
   <input type="file" name="video" id="video"><br><br/>
   <input type="submit" value="Save"></form>

我的控制器：

public function save()
{
    $storage_image_path = 'path';
    if ($_FILES["userfile"]["name"]) {
                move_uploaded_file($_FILES["userfile"]["tmp_name"], 'path' . $_FILES["userfile"]["name"]);

                $today_folders = date('Y') .'/'. date('m'). '/' ;


                if ( !file_exists(  $this->config->item("path") . 'big/' . $today_folders ) ){
                    $old_umask = umask(0);
                    mkdir( $this->config->item("path") . 'large/' . $today_folders, 0777, true );
                    umask($old_umask);
                }
                $filename       = $_FILES["userfile"]["name"];
                $filename2      = $filename;
                $extension   = end(explode(".", $filename));
                $extcnt      = strlen($extension) + 1;
                $fn_count    = strlen($filename) - $extcnt;
                $replacename = substr($filename, 0, $fn_count);
                $newfilename = $replacename . date("-d");
                $newfilename = $newfilename . '.' . $extension;
                $original_image = 'path' . $filename;
                $dimensions     = getimagesize($original_image);                   
                $width          = $dimensions[0];
                $height         = $dimensions[1];
                if ($width >= $height) {
                    $parametru = $width / 70;
                    $height    = round($height / $parametru);
                    $width     = 700;
                } else {
                    $parametru = $height / 300;
                    $width     = round($width / $parametru);
                    $height    = 300;
                }
                $config['image_library']  = 'gd2';
                $config['source_image']   = $original_image;
                $config['create_thumb']   = false;
                $config['maintain_ratio'] = true;
                $config['width']          = $width;
                $config['height']         = $height;
                $config['master_dim']     = 'width';
                $config['new_image']      = $storage_image_path . '/big/' . $newfilename;
                $this->load->library('image_lib', $config);
                $this->image_lib->resize();             
                if (!$this->image_lib->resize()) {
                    echo $this->image_lib->display_errors();
                    exit;
                }                  
                @unlink($original_image);

            } else {
                $newfilename = "no_photo.jpg";
                $image = 0;
            }
     $this->db->query("
                INSERT INTO videos (
                        image, 
                        video) 
                VALUES (?, ?)",
                array(
                    $image,  
                    0)
            );          
   //$this->tpl->display('multimedia/add.php');

}

使用此功能我上传图片，现在如何修改此方法上传和视频。请帮助我们我明白这个：

 if ($_FILES["userfile1"]["name"]) 
    {
        $filename_v       = $_FILES["userfile1"]["name"];
        $filenamev_2      = $filename;
        $config['upload_path'] = 'videos/mp4/'.$filename_v;
        $config['allowed_types'] = 'mov|mpeg|mp3|avi|mp4';

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

        if (!$this->upload->do_upload()) 
        {
            $error = array('error' => $this->upload->display_errors());
        }
        else 
        {
            $data = array('upload_data' => $this->upload->data());

        }
    }

我没有收到错误，但视频没有在指定路径中上传

默认情况下，上传例程要求文件来自名为userfile的表单字段，表单必须是＆＃34;多部分类型：

如果您想设置自己的字段名称，只需将其值传递给do_upload函数：

 $field_name = "some_field_name";
 $this->upload->do_upload($field_name)

了解详情

因此，在上面的视频文件上传方案中，应该有以下代码。

$this->upload->do_upload('video');

在codeigniter中上传图片和视频
