在codeigniter中上传多张图片

Question

我已经上传了我的 web 目录中的图像和数据库中的图像名称。当我上传图像时，目录中只有图像图像上传，数据库一个文件没有更新，但我想上传多个图像并更新多个数据库字段。

public function add_use_image(){
    include_once( dirname( __FILE__ ). '/SimpleImage.php' );
    include_once( dirname( __FILE__ ).'/_inc.php' );
    if(!empty( $_FILES['image']['name'] ) ){
    for( $i = 0; $i < count( $_FILES['image']['name'] ); $i++ ){
        $target= FCPATH. '/assets/uploads/ads/';
        $target1=$target.basename(date('m-d-Y_H:i:s').'_'.$_REQUEST['id'].'_'.@$_FILES['image']['name']);
        $img=basename(date('m-d-Y_H:i:s').'_'.$_REQUEST['id'].'_'.@$_FILES['image']['name']);
        move_uploaded_file(@$_FILES['image']['tmp_name'],$target1);
        $this->load->model( 'mads' );
        $this->mads->update( $_REQUEST['id'], array( 'image'. ( $i + 1 ) =>$img ), true );

    }
    }
        $response["success"] = 1;
        $response["image"]=$this->image_url('ads',$img);
        $response["message"] = "successfull.";

        echo json_encode($response);


}
