本文主要为大家分享一篇thinkphp5上传图片及生成缩略图公共方法,具有很好的参考价值,希望对大家有所帮助。一起跟随小编过来看看吧,希望能帮助到大家。

直接上代码,可以写在公共文件common和继承的基础类中,方便调用

/*
   * $name为表单上传的name值
   * $filePath为为保存在入口文件夹public下面uploads/下面的文件夹名称,没有的话会自动创建
   * $width指定缩略宽度
   * $height指定缩略高度
   * 自动生成的缩略图保存在$filePath文件夹下面的thumb文件夹里,自动创建
   * @return array 一个是图片路径,一个是缩略图路径,如下:
   * array(2) {
     ["img"] => string(57) "uploads/img/20171211\3d4ca4098a8fb0f90e5f53fd7cd71535.jpg"
     ["thumb_img"] => string(63) "uploads/img/thumb/20171211/3d4ca4098a8fb0f90e5f53fd7cd71535.jpg"
    }
   */
  protected function uploadFile($name,$filePath,$width,$height)
  {
    $file = request()->file($name);
    if($file){
      $filePaths = ROOT_PATH . 'public' . DS . 'uploads' . DS .$filePath;
      if(!file_exists($filePaths)){
        mkdir($filePaths,0777,true);
      }
      $info = $file->move($filePaths);
      if($info){
        $imgpath = 'uploads/'.$filePath.'/'.$info->getSaveName();
        $image = \think\Image::open($imgpath);
        $date_path = 'uploads/'.$filePath.'/thumb/'.date('Ymd');
        if(!file_exists($date_path)){
          mkdir($date_path,0777,true);
        }
        $thumb_path = $date_path.'/'.$info->getFilename();
        $image->thumb($width, $height)->save($thumb_path);
        $data['img'] = $imgpath;
        $data['thumb_img'] = $thumb_path;
        return $data;
      }else{
        // 上传失败获取错误信息
        return $file->getError();
      }
    }
  }
