codeigniter图片上传并调整大小-swfupload

如何解决codeigniter图片上传并调整大小-swfupload

|| 目前，我正在对网站的一部分进行编码，允许用户上传图片，然后选择要裁剪的图片区域。我想要这样的图像，而无需用户提交表单即可上传图像，因此我使用了名为swfupload的工具，可以成功上传图像，但是无法获得swfupload来创建缩略图或什至无法阅读缩略图方法。 下面是我的代码， 的PHP

public function upload()
    {
        $config[\'upload_path\'] = \"./media/uploads/users\";
        $config[\'allowed_types\'] = \'gif|jpg|png\';
        $config[\'max_size\']    = \'1000\';
        $config[\'max_width\']  = \'1024\';
        $config[\'max_height\']  = \'768\';
        $config[\'encrypt_name\']  = TRUE;

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


        if ( ! $this->upload->do_upload(\'Filedata\'))
        {
            $error = array(\'error\' => $this->upload->display_errors());
            //die(print_r($error));
        }
        else
        {
            $this->file = $this->upload->data();
            echo $this->file[\'file_name\'];
        }
    }

    public function thumbnail()
    {
                //lets just try and get thumbnail() talking to swfupload
        echo 1;
    }

swfupload js

window.onload = function () {
            swfu = new SWFUpload({
                // Backend Settings
                upload_url: \"http://lcl.moovjob.com/index.php/admin/users/upload\",post_params: {\"PHPSESSID\": \"<?php echo $this->session->userdata(\'session_id\'); ?>\" },// File Upload Settings
                file_size_limit : \"5 MB\",// 5MB
                file_types : \"*.jpg\",file_types_description : \"JPG Images\",file_upload_limit : \"0\",// Event Handler Settings - these functions as defined in Handlers.js
                //  The handlers are not part of SWFUpload but are part of my website and control how
                //  my website reacts to the SWFUpload events.
                file_queue_error_handler : fileQueueError,file_dialog_complete_handler : fileDialogComplete,upload_progress_handler : uploadProgress,upload_error_handler : uploadError,upload_success_handler : uploadSuccess,upload_complete_handler : uploadComplete,// Button Settings
                button_image_url : \"images/SmallSpyGlassWithTransperancy_17x18.png\",button_placeholder_id : \"spanButtonPlaceholder\",button_width: 180,button_height: 18,button_text : \'<span class=\"button\">Select Images <span class=\"buttonSmall\">(2 MB Max)</span></span>\',button_text_style : \'.button { font-family: Helvetica,Arial,sans-serif; font-size: 12pt; } .buttonSmall { font-size: 10pt; }\',button_text_top_padding: 0,button_text_left_padding: 18,button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,button_cursor: SWFUpload.CURSOR.HAND,// Flash Settings
                flash_url : \"/media/flash/swfupload.swf\",custom_settings : {
                    upload_target : \"divFileProgressContainer\"
                },// Debug Settings
                debug: true
            });
        };

我的Handlers js，尤其是上传成功方法，

function uploadSuccess(file,serverData) {
    try {
        var progress = new FileProgress(file,this.customSettings.upload_target);

        if (serverData.substring(0,7) === \"FILEID:\") {
            addImage(\"http://local.test.com/index.php/admin/users/thumbnail\");

            progress.setStatus(\"Thumbnail Created.\");
            progress.toggleCancel(false);
        } else {
            addImage(\"images/error.gif\");
            progress.setStatus(\"Error.\");
            progress.toggleCancel(false);
            alert(serverData);

        }


    } catch (ex) {
        this.debug(ex);
    }
}

我暂时要做的就是上传图像，然后返回1，所以我知道swfupload正在与控制器通信。我得到的只是上传成功或错误。     

解决方法

您可以将jquery文件uplaoder与jquery的Image area select插件一起使用。 这是图像区域选择插件的URL： http://odyniec.net/projects/imgareaselect/     ,我有些困惑，为什么不将缩略图方法添加到上传功能的末尾？据我所料，没有必要单独进行这些操作。 您已经在上传函数中检查了上传是否成功，因此在返回任何数据之前，请将文件名/目录传递给缩略图函数，创建缩略图，然后以这种方式将成功或失败返回给您的js。
