问题描述:

在godaddy空间，出现ecshop相册无法生成，经调试发现是 function move_image_file 内部copy函数出错 ,纠结原因是目标目录内文件过多，修改 reformat_image_name 让再分出一个目录来安置图片

function reformat_image_name($type, $goods_id, $source_img, $position='')
{
    $rand_name = gmtime() . sprintf("%03d", mt_rand(1,999));
    $img_ext = substr($source_img, strrpos($source_img, '.'));
    $dir = 'images';
    if (defined('IMAGE_DIR'))
    {
        $dir = IMAGE_DIR;
    }
    $sub_dir = date('Ym', gmtime());
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir))
    {
        return false;
    }
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir.'/source_img'))
    {
        return false;
    }
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir.'/goods_img'))
    {
        return false;
    }
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir.'/goods_img_2'))
    {
        return false;
    }
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir.'/thumb_img'))
    {
        return false;
    }
    if (!make_dir(ROOT_PATH.$dir.'/'.$sub_dir.'/thumb_img_2'))
    {
        return false;
    }
    switch($type)
    {
        case 'goods':
            $img_name = $goods_id . '_G_' . $rand_name;
            break;
        case 'goods_thumb':
            $img_name = $goods_id . '_thumb_G_' . $rand_name;
            break;
        case 'gallery':
            $img_name = $goods_id . '_P_' . $rand_name;
            break;
        case 'gallery_thumb':
            $img_name = $goods_id . '_thumb_P_' . $rand_name;
            break;
    }
    if ($position == 'source')
    {
        if (move_image_file(ROOT_PATH.$source_img, ROOT_PATH.$dir.'/'.$sub_dir.'/source_img/'.$img_name.$img_ext))
        {
            return $dir.'/'.$sub_dir.'/source_img/'.$img_name.$img_ext;
        }
    }
    elseif ($position == 'thumb')
    {
        if (move_image_file(ROOT_PATH.$source_img, ROOT_PATH.$dir.'/'.$sub_dir.'/thumb_img/'.$img_name.$img_ext))
        {
            return $dir.'/'.$sub_dir.'/thumb_img/'.$img_name.$img_ext;
        }else{
           if (move_image_file(ROOT_PATH.$source_img, ROOT_PATH.$dir.'/'.$sub_dir.'/thumb_img_2/'.$img_name.$img_ext))
           {
            return $dir.'/'.$sub_dir.'/thumb_img_2/'.$img_name.$img_ext;
           }
        }
    }
    else
    {
        if (move_image_file(ROOT_PATH.$source_img, ROOT_PATH.$dir.'/'.$sub_dir.'/goods_img/'.$img_name.$img_ext))
        {
            return $dir.'/'.$sub_dir.'/goods_img/'.$img_name.$img_ext;
        }else{
            if (move_image_file(ROOT_PATH.$source_img, ROOT_PATH.$dir.'/'.$sub_dir.'/goods_img_2/'.$img_name.$img_ext))
            {
                return $dir.'/'.$sub_dir.'/goods_img_2/'.$img_name.$img_ext;
            }
        }
    }
    return false;
}

上面代码中 goods_img_2 和 thumb_img_2 就是转存目录
