ajaxfileUpload ajax 上传图片使用

前台html:

<div class="b-mg15 img-text" room_id="<?= $items['id'] ?>">
                                <a class="modal-get">
                                    <img <?php if ($items['room_image']) {
                                        $url = Url::to('@web' . '/' . $items['room_image']);
                                        echo 'src' . '=' . $url;
                                    } ?> id="room_image">
                                </a>
                                <div class="pull-txt upload_image"
                                     room_id="<?= $items['id'] ?>" <?php if ($items['room_image']) echo "style="display: none"" ?>>
                                    <div class="b-mg15 t-mg60">
                                    <span class="glyphicon glyphicon-user f50">
                                    </span>
                                    </div>
                                    <a class="">
                                        点击上传会议室图片
                                    </a>
                                </div>

js代码：

  $(".img-text").click(function () {
        $("#fileToUpload").click();
        $("#fileToUpload").attr('room_id', $(this).attr('room_id'));
    });
    //选择文件之后执行上传
    $('#fileToUpload').on('change', function () {
        $.ajaxFileUpload({
            url: "<?=Url::toRoute('ajax-upload')?>",
            secureuri: false,
            fileElementId: 'fileToUpload',//file标签的id
            dataType: 'json',//返回数据的类型
            data: {_csrf: "<?=Yii::$app->request->getCsrfToken()?>", room_id: $(this).attr('room_id')},//一同上传的数据
            success: function (data) {
                //把图片替换
                $("#room_image").attr('src', data.result);
                window.location.reload();
            },
            error: function (data, status, e) {
                alert(e);
            }
        });
    });

后台 php 代码：

 /**
     * ajax 上传图片
     * @return string
     */
    public function actionAjaxUpload()
    {
        return json_encode(MeetRoomService::AjaxUploadImage());
    }

  /**
     * ajax 上传图片
     * @return string
     */
    public static function AjaxUploadImage()
    {
        $returnData = [];
        $company_id = Yii::$app->company->getId();
        $room_id = Yii::$app->request->post('room_id','');
        $room = MeetRooms::find()->where(['id'=>$room_id])->one();
        $typeArr = array("jpg", "png", "gif");//允许上传文件格式
        $path = 'meetRoomImg/' . $company_id.'/';
        $dirPath = 'meetRoomImg';
        if(!file_exists($dirPath))
        {
            mkdir($dirPath, 0777);
            chmod($dirPath, 0777);
        }
        if (!file_exists($path)) {

            mkdir($path, 0777);
            chmod($path, 0777);
        }
        if (isset($_POST)) {
            $name = $_FILES['upfile']['name'];
            $size = $_FILES['upfile']['size'];
            $name_tmp = $_FILES['upfile']['tmp_name'];
            if (empty($name)) {
                $returnData['error'] = '您还未选择图片';
                $returnData['code'] = 400;
                return $returnData;
            }
            $type = strtolower(substr(strrchr($name, '.'), 1)); //获取文件类型
            if (!in_array($type, $typeArr)) {
                $returnData['error'] = '请上传jpg,png或gif类型的图片！';
                $returnData['code'] = 400;
                return $returnData;
            }
            if ($size > (5000 * 1024)) {
                $returnData['error'] = '图片大小已超过5000KB';
                $returnData['code'] = 400;
                return $returnData;
            }
            $yCode = array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J');
            $orderSn = $yCode[intval(date('Y')) - 2011] . strtoupper(dechex(date('m'))) . date('d') . substr(time(), -5) . substr(microtime(), 2, 5) . sprintf('%02d', rand(0, 99));
            $pic_url = $path . '/' . date('Y-m-d') . $orderSn . '.' .$type;
            $pic_name = date('Y-m-d') . $orderSn . '.' .$type;
            if (move_uploaded_file($name_tmp, $pic_url)) { //临时文件转移到目标文件夹
                $room->room_image = $pic_url;
                $room->save(false);
                $returnData['error'] = '0';
                $returnData['result'] = $pic_url;
                $returnData['code'] = 200;
            } else {
                $returnData['error'] = '上传有误，清检查服务器配置！';
                $returnData['code'] = 400;
            }
            return $returnData;
        }
    }

注意问题：

上传成功之后没有执行回调函数。

打开ajaxfileupload.js拉到底下找到

[javascript] view plain copy
if ( type == "json" ) {
eval( "data = " + data );
}

改成：
[javascript] view plain copy
if ( type == "json" ) {
data = data.replace("<pre>","").replace("</pre>","");
//data = eval("("+data.replace("<pre>","").replace("</pre>","")+")");
