多个图像上传，调整大小并使用codeigniter保存到数据库

Question

我正在尝试使用codeigniter上传多个图片。这是场景

我如何上传多个图像并将图像位置保存到数据库中（因为我想在我的视图文件中显示上传的图像），在上传之前我还想重命名我的图像并将它们调整为大拇指＆＃39;大小

这是我的控制器：

    function uploadRoomImage(){

    $i = 0;
    $files = array();
    foreach ($_FILES as $key => $value) {
        if(!empty($value['name']))
        {

            $config['upload_path'] = 'assets/img/upload/rooms/';
            $config['allowed_types'] = 'jpg|jpeg';
            $config['file_name'] = $filename;
            $config['max_size'] = '2000';
            $config['remove_spaces'] = true;
            $config['overwrite'] = false;

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

            if (!$this->upload->do_upload($key))
            {
                $error = array('error' => $this->upload->display_errors());
            }
            else
            {
                $files[$i] = $this->upload->data();
                $i++;

                //load image library
                $this->load->library('image_lib');

                $config['image_library'] = 'gd2';
                $config['source_image'] = $image_data['full_path'];
                $config['new_image'] = $image_data['file_path'].'room_thumb/';
                $config['maintain_ratio'] = FALSE;
                $config['create_thumb'] = TRUE;
                $config['thumb_marker'] = '_thumb';
                // $config['overwrite'] = false;
                $config['width'] = 280;
                $config['height'] = 280;

                //initialize upload library using the config settings defined above.
                $this->image_lib->initialize($config);

                if (!$this->image_lib->resize()) {
                    $error = array('error' => $this->image_lib->display_errors());
                } else {
                    $this->image_lib->resize();
                }
                //i want send each image file location into db in here after resizing each image
            }
        }           
    }       

我可以上传多张图片，但我无法将他们的位置发送到我的数据库中，我也无法调整它们的大小。请帮忙

看起来您的$config['source_image'] = $image_data['full_path'];错过了附加到完整路径的文件名。您还应该为$config['new_image']添加该内容。

如果您想将数据上传到数据库，可能会create a model处理该操作。
