thinkphp表单上传文件并将文件路径保存到数据库中

上传单个文件，此文以上传图片为例，上传效果如图所示

创建数据库upload_img,用于保存上传路径

CREATE TABLE `seminar_upload_img` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`img_name` varchar(255) DEFAULT NULL COMMENT \'图片名称\',
`img_url` varchar(255) DEFAULT NULL COMMENT \'图片路径\',
`create_time` text,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=23 DEFAULT CHARSET=utf8;
在公共配置文件Common/Conf.php中连接数据库，并配置地址

return array(
        \'DB_TYPE\'=>\'mysql\',
    \'DB_HOST\'=>\'127.0.0.1\',
    \'DB_NAME\'=>\'seminar\',
    \'DB_USER\'=>\'root\',
    \'DB_PWD\'=>\'root\',
    \'DB_PORT\'=>3306,
    \'DB_PREFIX\'=>\'seminar_\',
    \'DB_CHARSET\'=>\'utf8\',
    
    \'SHOW_PAGE_TRACE\'=>true,
    
    /*地址替换*/
    \'TMPL_PARSE_STRING\'=>array(
        \'__UPLOAD__\'=>__ROOT__.\'/Public/Uploads\',
    ),
);

视图文件Upload/index.html中

<!DOCTYPE html>
<html>
    <head>
        <title></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <style type="text/css">
            #img{height:22px; border:#000 2px solid}
            #button{height:30px; width:100px;}
        </style>
    </head>
    <body>
        <div><notemply name="data">
                <img src="__UPLOAD__/{$data[\'img_url\']}" width="200" height="100"/>
            </notemply></div>
        <div class="result" >上传允许文件类型：\'jpg\', \'gif\', \'png\', \'jpeg\'图像文件后</div><br>
        <form action="{:U(\'upload/Upload\')}" method="post" enctype="multipart/form-data">
            <input type="file" name="image"/>
            <input type="submit" value="上传" id="button">
        </form>
    </body>
</html>

控制器UploadController.class.php中实现上传文件

namespace Home\Controller;
use Think\Controller;
class UploadController extends Controller {
    public function index() {
        $img=M(\'upload_img\');
        $sel=$img->order(\'create_time desc\')->find();
        $this->assign(\'data\', $sel);
        $this->display();
    }
    public function upload(){
         $upload_img=M(\'upload_img\');
          if(!empty($_FILES)){
              //上传单个图像
                $upload = new \Think\Upload();// 实例化上传类
                $upload->maxSize   =     1*1024*1024 ;// 设置附件上传大小
                $upload->exts      =     array(\'jpg\', \'gif\', \'png\', \'jpeg\');// 设置附件上传类型
                $upload->rootPath  =      \'Public/Uploads/\'; // 设置附件上传根目录
                $upload->savePath  =      \'\'; // 设置附件上传（子）目录
                $upload->saveName=array(\'uniqid\',\'\');//上传文件的保存规则
                $upload->autoSub  = true;//自动使用子目录保存上传文件 
                $upload->subName  = array(\'date\',\'Ymd\');
                // 上传单个图片
                $info   =   $upload->uploadOne($_FILES[\'image\']);
                if(!$info) {// 上传错误提示错误信息
                    $this->error($upload->getError());
                }else{// 上传成功 获取上传文件信息
                     $img_url=$info[\'savepath\'].$info[\'savename\'];
                     $data[\'img_url\']=$img_url;
                     $data[\'img_name\']=$info[\'savename\'];
                     $data[\'create_time\']=NOW_TIME;
                     $upload_img->create($data);
                     $result=$upload_img->add();
                     if(!$result){
                         $this->error(\'上传失败！\');
                     }else{
                         $this->success(\'上传成功\');
                     }
                }
          }
    }
}
