php - 如何通过恒定的上传路径上传多个图像

Question

我使用下面的代码上传多张图像，但当我通过不同的表单字段上传多张图像时显示错误。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

就像错误所说，由于这一行，您多次定义 uploadpath :

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

它一定在某个地方循环。从那里删除它(您只需要定义它一次，因此将其放在循环之外)，或者进行检查:

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