        $flag=$objUser->addadmin();


    }
    elseif($img_return==$errors)

                echo $img_return;

            //Errorrs are not shown

                //new locate('../index.php?error='.base64_encode());
    else
        new locate('../../index');

我已经检查了上传之前的图片，当check_img（）函数返回true 图像被上传并且它正确并且当返回$ errors时我想显示返回相同的错误为 $ errors 。 echo $ errors 无效。

要显示数组，您可以var_dump()或print_r()

试试这个......

if(isset($this->img)){
    ...any of this stuff...
}
      else{
         return $errors;
         print_r($errors);
      }
   }
}

应该这样做。

快乐的编码！

注意：我强烈建议您对此进行错误处理。页面的输出很难看，只是用户友好或优雅的方式来处理错误。

process_add_user.php文件中的错误未显示。当值为true但是返回为$ errors时将上载文件错误值不显示？
