上传文件时显示未定义的索引

我有一个错误说：

上传图片时未定义索引。

所有其他字段都在获取，但文件类型未设置。

下面的代码是我发布图像的第 1 页

<form name="adduser" id="adduser" class="form-horizontal form-bordered" action="{$ROOT_OBJECT}/addpointtypetodo/save" enctype="multipart/form-data">
                    <div class="form-group">
                        <label class="col-sm-2 control-label">Point Type Tittle*</label>
                        <div class="col-sm-4">
                            <input type="text" class="form-control" placeholder="Name" name="addPointTypeTittle" id="addPointTypeTittle" required>
                    </div>
                </div>
                <div class="form-group">

                </div>

                    <div class="col-sm-4">
                        <input type="file" class="form-control" placeholder="select file.." id="addPointTypeIcon" name="addPointTypeIcon">

                </div>
                <div class="form-group">
                    <label class="col-sm-2 control-label">Point Type Marker URL</label>
                    <div class="col-sm-4">
                        <input type="file" class="form-control" placeholder="select file.." id="addPointTypeMarker" name="addPointTypeMarker">
                    </div>

                <div class="form-group">
                    <div class="col-sm-4">
                        <input type="submit" class="btn btn-primary"  name="addPointTypeSubmit" id="addPointTypeSubmit" value="Save">
                    </div>
                </div>
            </form>

这是获取此图像的页面：

$uploadedFile = $_FILES['addPointTypeIcon']['tmp_name'];
            $pointTypeIcon = 'images/category/' . $_FILES['addPointTypeIcon']['name'];
            if (is_uploaded_file($uploadedFile))
            {
                $this->model->fields = array();
                move_uploaded_file($uploadedFile, $pointTypeIcon);
                array_push($this->model->fields, $pointTypeIndex);
                array_push($this->model->fields,  $pointTypeIcon);
                $this->model->saveIcon();

            }
//        }
//        if(isset($_FILES['addPointTypeMarker']))
//        {
            $uploadedFile = $_FILES['addPointTypeIcon']['tmp_name'];
            $pointTypeIcon = 'images/marker/' . $_FILES['addPointTypeMarker']['name'];
            if (is_uploaded_file($uploadedFile))
            {
                $this->model->fields = array();
                move_uploaded_file($uploadedFile, $pointTypeIcon);
                array_push($this->model->fields, $pointTypeIndex);
                array_push($this->model->fields,  $pointTypeIcon);
                $this->model->saveMarker();

            }

它说图像未设置。请帮忙。
