如何通过常量uploadpath上传多个imges

Question

我使用下面的代码上传多张图片，但是当我通过不同的表单字段上传多张图片时显示错误。我的代码是：

$image = 'image'.$i.$j;
      $image_store = $_FILES[$image]['name'];
define('uploadpath','../images/');
      $target = uploadpath. $image_store ;

，错误是

CONSTANT uploadpath Already defined

Answer 1

与错误相同，您多次定义uploadpath，因为这一行：

define('uploadpath','../images/');

它必须在某个地方循环。从那里删除它（你只需要定义一次，所以把它放出循环），或者检查一下：

if(!defined('uploadpath')) define('uploadpath','../images/');
