下面是yii框架实现图片上传功能的源码，希望能对大家有所帮助。

（学习视频分享：编程视频）

1、model

 false, 'extensions' => 'png, jpg,bmp,jpeg'],
        ];
    }
    public function attributeLabels()
    {
        return [
            't_img'=>'请上传文章图片',
            'verifyCode' => '请在右面输入验证码',
        ];
    }
 
 
    public function upload()
    {
        $imgName=time().rand(100,999).".".$this->t_img->extension;
        if ($this->validate()) {
            $this->t_img->saveAs('uploads/' .$imgName);
            $path='uploads/' .$imgName;
            return $path;
        } else {
            return false;
        }
    }
}
 
?>

2、控制器

 $data=Yii::$app->request->post();
            $data['t_addtime']=date('Y-m-d H:i:s');
            $upload->t_img = UploadedFile::getInstance($upload, 't_img');
            $path=$upload->upload();

3、视图层

 ['enctype' => 'multipart/form-data'],
        'method'=>'POST',
    ]
);?>

 
    

        

 
               >
        
        
    

        

            <?=$coursedraft['d_content']?>
        
    
    

        

           field($upload,'t_img')->fileInput()?>
        
    
    

        
            

                'btn btn-success'])?>
            
        
 
    


  id="c_id" />



registerJs($js);
?>
